Water Based Battery Safer than Lithium

Water Based Battery Safer than Lithium

A novel water based battery is said to be safer than lithium at half the cost.
A Boston-area startup called Alsym Energy has introduced a rechargeable water based battery that could match lithium-ion batteries’ performance at a fraction of the price.

In addition to using inexpensive, easily accessible materials like manganese and metal oxide, the novel battery is based on water, according to an initial report from Fast Company.

Being a water based battery means it avoids some of the main drawbacks of current batteries, such as the potential for lithium-ion battery fires and the negative impact of mining on the environment. And thanks to the use of non-toxic materials, the water based battery design is simpler to recycle, which is always a bonus.

Electric vehicles are becoming more important as the world’s nations step up their efforts to decarbonize the grid. That’s because they can aid in decarbonizing both transportation and supply of electricity through reduced tailpipe emissions and offer flexibility. Naturally, many automakers are tapping into the market by producing luxurious EVs; however, the expensive price tag remains to be a problem to this day. The costs are partly due to the lithium-ion batteries that are used in electric vehicles, which are too costly to make EVs that can compete in price tag with cars that run on fossil fuels.

This is where Alsym Energy, which recently emerged from stealth and secured $32 million from investors, comes in. According to a press release, with its first partner being an automaker in India, the startup wants to make it possible for manufacturers to produce cheaper electric vehicles.

“Our motivation was to make it affordable so that it could be widely deployed as opposed to niche,” Mukesh Chatter, CEO and co-founder of the startup, told Fast Company.

The Alsym Energy water based battery is inexpensive enough that it might be used in developing countries to store off-grid solar power. This is especially crucial for individuals who do not currently have access to energy.

 

What Makes the Water Based Battery Special?
The water based zinc battery makes use of other affordable, easily accessible components like manganese and metal oxide. Crucially, it does not contain cobalt, an expensive critical component of lithium batteries that also contributes to supply-chain health and environmental issues due to unethical mining practices. It also doesn’t use lithium at all, which requires resource-intensive salar brine extraction methods, mainly concentrated in conflict-prone regions of South America. Avoiding lithium and cobalt reliance is incredibly important as both metals have seen extreme price increases recently amid surging EV demand.

Lithium carbonate prices have skyrocketed over 750% in the last two years. And cobalt more than doubled in cost since 2020. These unstable dynamics will likely drive up prices of lithium-ion batteries for the foreseeable future. By swapping water for expensive, ethically fraught raw materials, the aqueous zinc batter stands to radically transform the energy storage calculus in terms of affordability, local manufacturing potential, and stability of supply chains.

According to the team behind Alsym Energy, the new design has “lithium-like performance.” But unlike the latter, Alsym Energy’s batteries are not flammable. This saves money as it doesn’t require special protection to avoid fires and gives the batteries additional applications, such as use in ships, where the industry is particularly concerned about fire risk.

If all goes to plan, Alsym Energy will start beta testing with its first customers in early 2023, with high-volume production beginning as early as 2025. The novel battery design will surely make waves globally; however, the company’s priority is to first make it affordable in low-income regions.

Renewable energy battery systems could harness eggshell proteins for electricity conduction

Renewable energy battery systems could harness eggshell proteins for electricity conduction

Chicken eggshells may be the answer to developing safer, sustainable and cost-effective rechargeable battery storage systems, according to new research.

Murdoch University Associate Professor Dr. Manickam Minakshi Sundaram, from the Center for Water, Energy and Waste at Harry Butler Institute, for a doctoral thesis has successfully developed a new mechanism associated with electrode materials and electrolytes, offering an alternative to the expensive and impractical power storage technologies of the past and present.

“We’ve found that chicken eggshells can be used as electrodes—a conductor of electricity—in powering batteries. Eggshells contain a high level of calcium carbonate, and when they are baked and crushed, their chemical compositions change and they become a more efficient electrode and conductor of power,” Dr. Minakshi said.

“The current lithium-ion batteries used for renewable energy storage typically use fossil fuels.

“Repurposing a bio-waste product like eggshells could add considerable value to the renewable energy market. They also offer a potentially safer option, as the current lithium battery technologies are high-cost and potentially unsafe in the event of catastrophic failure.”

As the world continues to prioritize renewable energy sources, this breakthrough marks a significant step forward, offering hope for a greener and more sustainable future.

The study, conducted by Dr. Minakshi as part of his higher doctorate thesis with Flinders University, focused on the development of sustainable electrodes in aqueous-based energy storage technology.

“The implications of this study go beyond scientific discovery,” Dr. Minakshi said.

“Chicken eggs and related products are used in large quantities in the food processing and manufacturing sectors, households, the nutrition industry and even in the pharmaceutical industry, but their shells are typically sent as solid waste to landfill.

“However, eggshell and shell membranes contain a range of active chemical compounds that can be used. The reversibility of this new approach allows for efficient energy storage and retrieval. The study demonstrates that highly conductive aqueous lithium and sodium electrolytes with varying salt concentrations have the potential to replace existing non-rechargeable primary batteries. The discovery holds the promise of high energy capacity, long cycle life and affordability in aqueous batteries.”

By incorporating suitable additives such as biodegradable redox polymers, titanium boride/sulfide (TiB2, TiS2), or bismuth oxide (Bi2O3) compounds, the electrodes can be further modified to improve their performance.

“The potential applications of this breakthrough are immense,” Dr. Minakshi said. “We could transition from a linear economy to a circular economy, reducing, reusing and recycling waste improving both sustainable development and addressing waste management.”

The studies on sustainable electrode materials have also been extended to other biowaste including chitosan derived from crustaceans, mango seed husk, and grape marc from wineries. From these biowastes, N-doped carbon was derived, which exhibits excellent electrochemical performance.

UK Government launches first licensing round for carbon storage projects

UK Government launches first licensing round for carbon storage projects

Operated by the North Sea Transition Authority (NSTA), the licensing round is inviting bids for projects in 13 areas within the North Sea and will be open rob ifs until 13 September. Plots of land are being offered off the coast in Aberdeen, Teesside, Liverpool and Lincolnshire.

The chosen 13 areas are “a mixture of saline aquifers and depleted oil and gas field storage opportunities”, the NSTA said in a statement, adding that it has “fully considered issues including co-location with offshore wind… environmental issues and potential overlaps with existing or future [oil and gas] licences”.

It is expected that the new licences will be awarded in early 2023. Applicants will also need to secure a lease from The Crown Estate or Crown Estate Scotland, as they would if they were applying to host offshore wind. The timelines for commencing the injection of carbon dioxide will depend on the project sizes and the approaches of the bidding companies, but the NSTA expects some projects to come online within six years of being granted a license and lease.

To date, the UK Government has only issued six licences to carbon storage projects in the North Sea. It first began issuing licenses in 2010, under the Energy Act of 2008.

The launch of the new licencing round, which is set to be the first of many through to 2030 and beyond, has been taken “in response to unprecedented levels of interest from companies eager to enter the market”, the NSTA has stated. These companies include existing oil and gas firms and new firms created to develop CCS technologies, often working in partnership.

NSTA boss Andy Samuel said: “This is an important day on the path to net-zero emissions. In addition to the huge environmental benefits of significantly reducing carbon dioxide emissions into the atmosphere, the facilities will provide opportunities for many thousands of highly-skilled jobs.

“Carbon storage is going to be needed across the world. There is growing investor appetite and we are keen to accelerate the development of the carbon storage sector so that the UK is well-positioned to be a global leader.”

The NSTA was known as the Oil and Gas Authority (OGA) prior to this March. Oil and gas activities are still its primary remit.

 

Policy vision, market stimulation

The UK’s decision to legislate for net-zero by 2050, made under Theresa May’s Government in 2019, provided the foundation for a new groundswell of interest in carbon capture and storage (CCS). Efforts to scale the sector had been made in the 2010s, but the Government’s decision to axe a £1bn fund to commercialise CCS technologies in 2015 was a major spanner in the works.

On the policy piece, the UK Government’s Ten-Point Plan, published in November 2020, envisions the creation of four industrial clusters utilizing CCS – the first of which should come online fully this decade. Policymakers have emphasised the importance of public-private collaboration in commercialising CCS technologies and scaling them up rapidly. The Ten-Point Plan’s specific target is for the UK to capture at least 20 million tonnes of CO2 annually by 2030, but some believe that a capacity of just 10 million tonnes will be likely within this timeframe.

The Carbon Capture and Storage Association has pointed out that the Climate Change Committee (CCC) has recommended that the UK aims to bring 22-30 million tonnes of annual CCS capacity online by 2030. Achieving this aim will require at least £1.2bn of funding by the Association’s estimates.

CCS has been described by the CCC as a “non-optional” component of the UK’s net-zero transition.

However, significant concerns remain around whether it will truly be used to address emissions from hard-to-abate sectors. MPs and researchers have questioned whether sectors that are easier to abate could simply purchase up credits, leaving none for heavy emitting sectors like steel. There are also concerns that the use of CCS could be used as an excuse to de-prioritise emissions reductions, which could be risky in terms of climate impact, as CCS technologies are in their relative infancy at a commercial scale.

The workplace of the future: smart, sustainable, holistic

The workplace of the future: smart, sustainable, holistic

The workplace as we know it has evolved dramatically during the Covid-19 pandemic, expanding into our homes and complex digital-physical spaces. As organisations and their employees continue to navigate hybrid working arrangements this year, how can technology help to shape green and conducive workplaces of the future?

Many new innovations are aimed at helping workplaces save energy. While energy efficiency may not be the snazziest of climate solutions, it remains a potent and cost-effective way to slash emissions without major reworks of existing infrastructure. The International Energy Agency (IEA) has projected that low-cost measures, such as better ventilation and LED lighting, if implemented globally, could slash 3.5 gigatonnes worth of carbon emissions a year.

The savings would amount to 40 per cent of the emissions that need to be abated to limit global warming to 2 degrees Celsius. With the increased focus on climate mitigation, energy efficiency solutions for the built sector is now a US$340 billion market globally that is set to grow by over 8 per cent through 2027.

In addition, in Singapore, energy efficiency incentives like the Green Mark Incentive Scheme are encouraging companies to pursue smart, sustainable and predictive solutions in the workplace. Companies are paying closer attention to their carbon footprint to support sustainability goals, and this requires more tools to monitor and optimise utilities consumption.

These tools usually come in the form of building intelligence systems, such as SP Digital’s GET Control. The system uses AI and IoT to optimise and regulate air-conditioning and maximise energy efficiency in real-time, based on changes in occupancy, current weather conditions and forecast data. The smart damper system, for example, divides large open-plan office spaces into micro-zones to enable better air-flow distribution and control. With predictive intelligence working together with all the sensors and smart dampers, data is sent wirelessly to a central control unit that recommends and adjusts the dampers dynamically such that the desired temperatures are met, making the office energy efficient and comfortable.

Clement Cheong, SP Digital’s vice president of sales and customer operations, says that GET Control responds to the needs of corporate real estate owners and commercial landlords in Singapore.

“Landlords are seeing more occupants coming into work and at different times,” he says. “They need to adapt their buildings and systems to cope with this change dynamically. For example, they do not need as much cooling or fresh air supply at non-peak or low occupancy periods.”

Moreover, he adds that the pandemic has also made employees even more conscious of indoor environmental quality. “They want to have visibility into IAQ (Indoor Air Quality) and the building’s measures to monitor and improve IAQ. Even though occupants may spend less time in the office, they want a better, healthier indoor experience.”

He explains that currently, building owners or tenants have limited visibility into indoor air quality in offices and limited ability to intelligently control it. Traditional air side control and management technologies tend to be “reactive”, that is, facility managers make adjustments when occupants complain of any indoor thermal discomfort. Because such technologies do not take into account dynamic changes in ambient temperatures, they are not as energy efficient as a system with real-time tracking capabilities like GET Control.

He shares a case study from an educational institution in Singapore, where facility managers were faced with frequent occupant complaints about hot and cold spots in the office. Besides the fact that facility managers had to make time-consuming manual adjustments, the building’s cooling efficiency was poor, resulting in high energy use and carbon emissions. When SP Digital’s GET Control was deployed, the site saw more than 30 per cent airside cooling energy savings, enhanced thermal comfort and indoor air quality for employees, and improved operations and productivity.

On a larger scale, some multinational corporations are leading the way in greening their offices, and their examples might provide insights into the future of the sustainable workplace. One of them is Meta, which operates the social media platform Facebook and aims to achieve a 50 per cent reduction in carbon by 2030. At its 260,000 square-feet office in Singapore, spread over four floors at Marina One Tower, this target has translated into environmental control systems that use the latest in automated sensor technology, which can optimise even the smallest indicators of energy efficiency. Numerous sensors are in place to measure temperature, air, light and motion open spaces, meeting rooms and lifts.

Apart from office management, Meta Singapore also uses technology to assist employees to adopt carbon reducing behaviours, and, while in the workplace, to holistically analyse their carbon footprint across the product supply chain, recycling, water and waste management.

Looking ahead globally, the journey to make buildings more sustainable will be a long one. Currently, the built environment is responsible for nearly 40 per cent of all greenhouse gas emissions in the world. According to a report by the International Energy Agency (IEA), the 2020 pandemic caused a drop in the buildings sector carbon emissions, followed by a moderate rebound in 2021, but buildings are not on track to achieve carbon neutrality by 2050.

In Singapore, energy efficiency remains a core tenet of the city-state’s decarbonisation pathway, even as longer-term solutions such as carbon capture and clean energy imports are being considered for the next few decades. Power generation firms are provided subsidies to upgrade their turbines and software; a similar fund is in place for building owners to buy more efficient air-conditioning systems and install motion sensors that automatically switch off appliances when not needed. Buildings contribute close to 15 per cent of Singapore’s national emissions — the high fraction resulting from the almost complete urbanisation of the island-state.

As part of its efforts to reach net-zero emissions around 2050, the government wants 80 per cent of buildings in Singapore – both old and new – to adopt energy efficiency measures by 2030, up from 50 per cent today.

There is growing awareness among businesses that greening their offices makes economic and environmental sense. The Singapore Building and Construction Authority’s Green Mark Incentive for Existing Buildings – a $100 million fund started to co-sponsor the adoption of energy-efficient technologies in existing buildings – has been fully committed, as has a separate $50 million fund which does the same for small and medium enterprises.

This suggests that more landlords in Singapore understand that the initial outlays of such green investments may be high, but returns in the long run justify the cost, given the changes in expectations of workplace experience, energy efficiency and sustainability in post-pandemic times.

How big finance can scale up sustainability

How big finance can scale up sustainability

Addressing the ever-worsening climate crisis will require the largest sustained movement of capital in history. At least $100 trillion must be invested over the next 20-30 years to shift to a low-carbon economy, and $3-4 trillion of additional annual investment is needed to achieve the Sustainable Development Goals by 2030 and stabilise the world’s oceans.

Mobilising these huge sums and investing them efficiently is well within the capacity of the global economy and existing financial markets, but it will require fundamental changes to how these markets work. In particular, traditional financial institutions will need help in sourcing the right projects, simplifying the design and negotiation of transactions, and raising the capital to fund them.

Many sustainability ideas are small-scale, which partly reflects the nature of innovation, whereby ideas are developed, tested, and, if successful, eventually copied. But the disconnect between those developing sustainability projects and the world of traditional finance means that scaling such initiatives is not straightforward.

At the risk of oversimplifying, sustainability advocates may be suspicious of “Big Finance” and its history of funding unsustainable industries. Investors, on the other hand, may be wary of idealistic approaches that ignore bottom-line realities, and might not be interested in small-scale transactions.

Given this disconnect, how do we scale up sustainable projects from small investments to the $100 million-plus range that begins to attract Big Finance and thus the trillions of dollars needed to make a global difference?

 

The disconnect between those developing sustainability projects and the world of traditional finance means that scaling such initiatives is not straightforward.

 

Three steps, in particular, are necessary. First, securitisation techniques should be employed to aggregate many smaller projects into one that has enough critical mass to be relevant. Securitisation got a bad name in 2007-08 for its role in fueling the subprime mortgage crisis that brought the developed world to the brink of financial ruin.

But when properly managed, joint financing of many projects reduces risk, because the likelihood that all will have similar financial and operational issues simultaneously is low. For the resulting whole to interest investors, however, the numerous smaller projects need to have common characteristics so that they can be aggregated. This cannot be done after the fact.

For example, we need to develop common terms and conditions for pools of similar assets, as is already happening in the US residential solar market. Then, we need to explain the fundamentals of securitisation to more potential grassroots innovators through regional conferences that bring together financiers and sustainable-project developers.

Second, we must reduce the complexity of key transaction terms and make it easier to design and negotiate the specifics of instruments used to invest in sustainable projects. In established financial markets, replicating significant parts of previous successful deals is much easier than starting from scratch for each transaction. This approach works because many of the terms and conditions for subsequent deals have already been accepted by key financial players.

Making successful innovations more visible to investors is therefore crucial. To that end, we should establish a high-profile, open-source clearinghouse of previous sustainable projects, including those that have been successfully funded and those that failed. This would be similar to many existing financial-sector databases but freely available, with reputable third-party oversight to ensure accuracy.

Third, the range of funding sources for sustainable projects needs to be expanded and made more transparent. Because sustainability investments may offer lower returns according to historic financial-market metrics, traditional asset-allocation practices, against the backdrop of “efficient markets,” would imply reduced attractiveness.

But historic benchmarks do not sufficiently factor in the exploding field of impact investing, which embraces different return and time thresholds and now accounts for about $2.5 trillion of assets. Securitising tranches of different kinds of impact investing could prove to be a game changer for sustainability financing.

It would thus make sense to create an open-source database of investor appetite – similar to the project database mentioned above – that is searchable by innovators and designers of new sustainable projects. This would make it easier to identify investors – equity, credit, or some hybrid – who might commit funding. The database could be housed in an organization such as the International Finance Corporation, the United Nations, or the Global Impact Investing Network.

There are encouraging precedents. The green bond market started just over a decade ago, and total issuance already could reach $1 trillion this year. And a critical mass of the financial world attended the UN Climate Change Conference (COP26) in Glasgow last November. Under the leadership of UN Special Envoy Mark Carney, the Glasgow Financial Alliance for Net Zero (GFANZ) has made $130 trillion in climate-finance commitments.

In 1983, Muhammad Yunus founded Grameen Bank in order to provide banking services, and especially loans, to individuals (primarily women) previously considered to be “un-bankable.” By the time Yunus won the Nobel Peace Prize in 2006, “micro-lending” had become a global phenomenon, with traditional financial institutions involved in securitizing these loans.

The financial revolution that Yunus started transformed retail lending, streamlined how such transactions are structured, and tapped a new source of scaled investment capital. To help address today’s existential sustainability challenges, capital markets and their major players need to be more innovative still and open the door to non-traditional, even disruptive, voices and ideas.

Is Asia high on hydrogen?

Is Asia high on hydrogen?

Judging from how often the H-word came up during this week’s marathon dialogues held to discuss the energy transition in Asia, it is clear that hydrogen is having its big moment.

Even as players in the region acknowledge that it might take some time before their investments in low-carbon hydrogen pay off, many are pinning their hopes on the hydrogen economy redrawing the energy map of tomorrow.

At two separate conferences this week, high-level representatives from energy institutes based in Japan and Australia were especially bullish on the prospects of hydrogen. Both countries are leading the charge in Asia to roll out technological solutions to promote the alternative fuel as part of their energy transition strategies.

Speaking at the APAC Energy Conversations, a virtual event organised as part of the Energy Industries Council (EIC)’s biannual flagship conference, Miranda Taylor, who leads National Energy Resources Australia (NERA), said that her organisation is particularly focused on “the hydrogen journey”.

 

Australia’s energy institutes are now focused on helping the island continent build a renewable hydrogen industry, said Miranda Taylor, chief executive of NERA (top right in picture) at the recent EIC-APAC Energy Conversations. NERA is also working with authorities to ensure that the decommissioning of coal in Asia is up to standard. [Click to enlarge] Source: GE Gas Power

NERA is a non-profit working to support the island continent’s energy transition, by coordinating the provision of seed funding for companies and innovators. “Within the industry, we all know that the hydrogen story is a complex one. It is also an ‘unproven’ story, because there are doubts about how clean the fuel will finally be. Nonetheless, considerable investments in hydrogen are pouring in,” she said.

Professor Tatsuya Terazawa, chairman and chief executive of Japan’s Institute of Energy Economics, similarly believes that green hydrogen – hydrogen generated from renewables –  is the answer if Asia is seeking a “pragmatic approach”.

 

Not cheap nor lucrative yet

The region, unfortunately, cannot enjoy the growth potential of solar and wind power, due to its land and weather limitations, said Terazawa, at a Singapore International Energy Week (SIEW) dialogue session on Monday. “There are also no transmission lines connecting Asia with regions rich in these renewables. But we can innovate and find a way to lower the costs of transporting hydrogen and it will alter the calculus of the energy transition in Asia,” he said.

It remains unclear how clean or lucrative hydrogen can be. Hydrogen has been the promised fuel of the future since the 1970s but there have been many false starts in the past decade. More than 95 per cent of the hydrogen used today, commonly known as ‘grey hydrogen’, is extracted from natural gas. The process of manufacturing hydrogen involves electrolysing water to separate hydrogen atoms from oxygen and is hugely water and energy-intensive.

Over the past few years, the industry has been turning to low-carbon energy sources such as renewables and nuclear power to extract hydrogen, but it is still prohibitively expensive. Within the region, countries like Singapore are opting to develop subsea cables to import renewable energy from its neighbours, rather than hedge bets on hydrogen.

The International Energy Agency (IEA), in the Global Hydrogen Review, its new annual publication focused on tracking progress in hydrogen production and demand, estimates that putting the hydrogen sector on a path consistent with global net zero emissions by 2050 requires US$1.2 trillion in investments by 2030.

To curb climate change, about US$90 billion of public money needs to be channelled into clean energy innovation worldwide as quickly as possible – with around half of it dedicated to hydrogen-related technology, the report said.

 

Within the industry, we all know that the hydrogen story is a complex one. It is also an ‘unproven’ story, because there are doubts about how clean the fuel will finally be.

Miranda Taylor, CEO, National Energy Resources Australia (NERA)

 

In Asia, Japan is spearheading the Hydrogen Energy Ministerial (HEM) meeting, a multilateral initiative organised to create consensus on hydrogen-related collaborations. According to the Institute of Energy Economics, for the region to realise net-zero carbon emissions by 2050, annual costs could go up to 2.9 per cent of each country’s gross domestic product (GDP).

“It is difficult to get a region that is the growth centre of the world to give up on growth,” said Terazawa.

Japan is banking on transforming hydrogen into ammonia to make it much less expensive to carry in the absence of transmission pipelines, and Terazawa thinks it is the right way forward. To transport hydrogen as a liquid, it needs to be cooled to a temperature of -252 °C, while ammonia can be carried as a liquid at just -33 °C, explained Terazawa.

“It will be the cheapest option for Asia if it wants to decarbonise,” he said.

 

Where will the gold rush lead to? 

Referring to Malaysia’s energy ministry’s announcement this week that it will limit renewable energy exports to Singapore, Andrew Bedford, director of energy transition at US-based consultancy Jacobs, said that governments in Asia are feeling the heat to meet their net-zero targets. This might fuel a more nationalistic mindset when it comes to the way they think about renewables and energy, he said.

“At the same time, it means that [countries that used to be] major energy importers now have an opportunity to invest in emerging areas of opportunities, diversify their energy mix and own a share of a new market,” said Bedford.

Describing the surge of investments in hydrogen-related infrastructure as a “green gold rush”, Bedford said that bigger players are now snapping up “the best areas of land” that are suited to such development.

In terms of coming up with comprehensive hydrogen plans, Southeast Asia still has a lot of catching up to do, said Bedford. The number of countries with hydrogen strategies has increased from just three in 2019 to 17 today, but none are from the region.

Singapore is working on one right now, though it is also taking a cautious approach in doing so. The island state announced on Monday that it will be awarding S$55 million to research projects that are focused on improving the technical and economic feasibility of low-carbon technologies, particularly hydrogen and carbon capture, utilisation and storage (CCUS), to enable local deployment in the future.

By 2035, Singapore aims to import up to 30 per cent of its power supply by 2035 in a bid to diversify the gas-dependent nation’s energy mix with renewables.

Minister for Trade and Industry Gan Kim Yong, delivering a speech at SIEW, spoke about low-carbon hydrogen’s potential to “be a game-changer for Singapore’s energy transition”.

 

Speaking at the opening of Singapore International Energy Week (SIEW), Minister for Trade and Industry Gan Kim Yong said that the move to import low-carbon energy will be a “key needle mover” in Singapore’s energy transition in the near to medium term. Image: SIEW

 

For hydrogen to be deployed meaningfully, especially for the power sector, global supply chains and proper infrastructure for hydrogen need to be established and the costs of hydrogen transport, storage and use need to be competitive, said Gan.

 

Consigning coal to history 

Experts at the energy dialogues said that while the viability of green hydrogen is being hammered out, gas is likely to play a role as a bridging fuel in the region’s energy transition.

Shantanu Som, engineering director for GE Gas Power, advocates for a more measured approach. “Companies are getting mixed signals on where they should be headed for. On one hand, Australia is aspiring to be the hydrogen hub for Asia and the government is taking very bold steps. On the other hand, you have China, which has a five-year plan but is just putting small stepping stones in-between in a very cautious manner,” he said.

China’s new road map, launched on Tuesday, pledged to hit peak greenhouse gas emissions by the end of the decade but stopped short of firm commitments to reduce reliance on coal.

When leaders gather at the COP26 summit in Glasgow this weekend, hydrogen is unlikely to prominently feature on their discussion agenda. The world needs to work on phasing out coal first, said energy experts.

Organisations working with authorities on pushing for the energy transition will need to have the capacity to make sure that coal decommissioning is done to the highest standards, said Taylor.

“The Asia-Pacific region, including Australia, has a considerable amount of offshore oil and gas infrastructure, which will need to be decommissioned or repurposed in the next decades. For a just transition to happen, we have to be realistic and make sure that workers are retrained, that they will be equipped with different skills and capabilities to work in a different industry,” she said.

Hitting global climate target could create 8 million energy jobs

Hitting global climate target could create 8 million energy jobs

If some politicians are to be believed, taking sweeping action to meet the goals of the Paris climate agreement would be calamitous for jobs in the energy sector. But a study suggests that honouring the global climate target would, in fact, increase net jobs by about 8 million by 2050.

The study – in which researchers created a global dataset of the footprint of energy jobs in 50 countries including major fossil fuel-producing economies – found that currently an estimated 18 million people work in the energy industries, which is likely to increase to 26 million if climate targets are met.

Previous research suggests that pro-climate polices could increase net energy jobs by 20 million or more, but that work relied only on empirical data from the Organisation for Economic Co-operation and Development (OECD) countries and generalised the results for the rest of the world using a multiplier. But the data varies dramatically across regions, driven by differences in technology and rates of unionisation, among other factors. For instance, extracting 1m tonnes of coal in India takes 725 workers, versus 73 in the US.

The latest analysis, published in the journal One Earth, combined such employment factors across a global dataset (including key fossil fuel, non-OECD economies such as Russia, India and China) with an integrated assessment model, which combines climate and economic estimates to predict the costs of climate change.

“This dataset makes the analysis more grounded in … reality, rather than using a multiplier,” said one of the study’s authors, Dr Sandeep Pai, who led the analysis as part of his PhD at the institute for resources, environment and sustainability at the University of British Columbia in Canada.

Under the target scenario of global temperatures being held well below 2C of pre-industrial levels, of the total jobs in the energy sector in 2050, 84% would be in the renewables sector, 11% in fossil fuels, and 5% in nuclear, the analysis found. Although fossil-fuel extraction jobs – which constitute the lion’s share (80%) of current fossil fuel jobs – will decline steeply, those losses should be offset by gains in solar and wind manufacturing jobs that countries could compete for, the researchers estimated.

However, while most countries will experience a net job increase, China and fossil fuel-exporting countries such as Canada, Australia and Mexico could have net losses.

Undoubtedly, there will be winners and losers. The winners will be people who take these jobs in the renewable sector, and there are the health benefits of fresh air and cleaner cities – but there will also be people, companies and governments who lose out, said Pai.

“That’s why … we want to work towards a ‘just’ transition, make sure nobody’s left behind,” he said. “The point is that unless politics and social context of different countries align, I think this technological transition will not happen soon.”

Johannes Emmerling, an environmental economist at the RFF-CMCC European Institute on Economics and the Environment in Italy, another author of the study, acknowledged that the analysis did not account for the gaps in skills.

People working in the fossil fuel industry do not necessarily have the expertise or the experience to carry out jobs in the renewable sector, but given that there are few estimates of jobs as the world aims to forge a greener future, the focus was on firming up estimates, he said, adding that skills were the next avenue of research.

Climatech Corp and Inovues are the winners of the inaugural CapitaLand Sustainability X Challenge (CSXC) 2021, a global hunt for sustainability innovations in the built environment.  

Both winners will receive S$50,000 (US$38,000) each to fund, test and implement their innovations at selected CapitaLand properties worldwide, as well as mentorship by a CapitaLand business leader. 

Climatech won the Most Innovative Award for their water treatment process to treat cooling water without the use of chemicals or power, while Inovues won the High Impact Award for their insulating glass retrofit technology.  

Climatech’s solution, known as the ClimaControl Quantum Resonance Water, is a novel solution that allows cooling water to be recycled for other uses in buildings, such as plant irrigation or toilet flushing. Based in Singapore, the company’s solution uses photon vibration frequency technology to treat cooling tower, achieving 60 to over 90 per cent of water savings, and one to over five per cent of energy savings.

From the United States, Inovues’ insulating glass technology reduces energy consumption to heat or cool buildings by up to 40 per cent without compromising on the luminosity indoors. The smart glass technology can be retrofitted on to existing windows, and reduces noise and heat gain inside a building by up to 10 times. Windows are the Achilles’ heel of the built environment, said one of the judges, Rushad Nanavatty, managing director or urban transformation at RMI.

 

The two winners will also have the chance to showcase their innovations to senior global business leaders, investors and policymakers at the annual Ecosperity Week sustainability event organised by Temasek. 

“Research and innovation leading to commercialisation is a space where public and private sectors must collaborate. Research can be long-dated and involves high risk. Governments must support and fund it. Innovation and commercialisation of products of research require entrepreneurial acumen and nimble responses. This is where many enterprises have strengths,” said Minister for Sustainability and the Environment of Singapore, Grace Fu, who was the guest-of-honour at the grand finale.

The themes for the inaugural challenge were low carbon transition, water conservation and resilience, waste management and circular economy, and healthy and safe buildings. 

The winning solutions emerged from a shortlist that included a portable, self-powered energy generator cum chiller, a thermal insulation curtain wall, a smart waste bin which uses artificial intelligence to sort waste, and an indoor air disinfection solution. All six finalists and selected participants will have a chance to pilot their innovations at selected CapitaLand properties worldwide.

At the grand finale, CapitaLand also announced a S$50 million innovation fund to support the test-bedding of sustainability and other high-tech innovations in the built environment. 

Lee Chee Koon, CapitaLand’s group chief executive officer said: “The inaugural CapitaLand Sustainability X Challenge has allowed us to uncover promising innovations that we can potentially implement at our properties across the globe, and help us achieve our ambitious targets set out in our 2030 Sustainability Master Plan.”

MIT engineers have discovered a completely new way of generating electricity

MIT engineers have discovered a completely new way of generating electricity

Tiny Particles Power Chemical Reactions

A new material made from carbon nanotubes can generate electricity by scavenging energy from its environment.

MIT engineers have discovered a new way of generating electricity using tiny carbon particles that can create a current simply by interacting with liquid surrounding them.

The liquid, an organic solvent, draws electrons out of the particles, generating a current that could be used to drive chemical reactions or to power micro- or nanoscale robots, the researchers say.

“This mechanism is new, and this way of generating energy is completely new,” says Michael Strano, the Carbon P. Dubbs Professor of Chemical Engineering at MIT. “This technology is intriguing because all you have to do is flow a solvent through a bed of these particles. This allows you to do electrochemistry, but with no wires.”

In a new study describing this phenomenon, the researchers showed that they could use this electric current to drive a reaction known as alcohol oxidation — an organic chemical reaction that is important in the chemical industry.

Strano is the senior author of the paper, which appears today (June 7, 2021) in Nature Communications. The lead authors of the study are MIT graduate student Albert Tianxiang Liu and former MIT researcher Yuichiro Kunai. Other authors include former graduate student Anton Cottrill, postdocs Amir Kaplan and Hyunah Kim, graduate student Ge Zhang, and recent MIT graduates Rafid Mollah and Yannick Eatmon.

 

Unique properties

The new discovery grew out of Strano’s research on carbon nanotubes — hollow tubes made of a lattice of carbon atoms, which have unique electrical properties. In 2010, Strano demonstrated, for the first time, that carbon nanotubes can generate “thermopower waves.” When a carbon nanotube is coated with layer of fuel, moving pulses of heat, or thermopower waves, travel along the tube, creating an electrical current.

That work led Strano and his students to uncover a related feature of carbon nanotubes. They found that when part of a nanotube is coated with a Teflon-like polymer, it creates an asymmetry that makes it possible for electrons to flow from the coated to the uncoated part of the tube, generating an electrical current. Those electrons can be drawn out by submerging the particles in a solvent that is hungry for electrons.

To harness this special capability, the researchers created electricity-generating particles by grinding up carbon nanotubes and forming them into a sheet of paper-like material. One side of each sheet was coated with a Teflon-like polymer, and the researchers then cut out small particles, which can be any shape or size. For this study, they made particles that were 250 microns by 250 microns.

When these particles are submerged in an organic solvent such as acetonitrile, the solvent adheres to the uncoated surface of the particles and begins pulling electrons out of them.

“The solvent takes electrons away, and the system tries to equilibrate by moving electrons,” Strano says. “There’s no sophisticated battery chemistry inside. It’s just a particle and you put it into solvent and it starts generating an electric field.”

“This research cleverly shows how to extract the ubiquitous (and often unnoticed) electric energy stored in an electronic material for on-site electrochemical synthesis,” says Jun Yao, an assistant professor of electrical and computer engineering at the University of Massachusetts at Amherst, who was not involved in the study. “The beauty is that it points to a generic methodology that can be readily expanded to the use of different materials and applications in different synthetic systems.”

 

Particle power

The current version of the particles can generate about 0.7 volts of electricity per particle. In this study, the researchers also showed that they can form arrays of hundreds of particles in a small test tube. This “packed bed” reactor generates enough energy to power a chemical reaction called an alcohol oxidation, in which an alcohol is converted to an aldehyde or a ketone. Usually, this reaction is not performed using electrochemistry because it would require too much external current.

“Because the packed bed reactor is compact, it has more flexibility in terms of applications than a large electrochemical reactor,” Zhang says. “The particles can be made very small, and they don’t require any external wires in order to drive the electrochemical reaction.”

In future work, Strano hopes to use this kind of energy generation to build polymers using only carbon dioxide as a starting material. In a related project, he has already created polymers that can regenerate themselves using carbon dioxide as a building material, in a process powered by solar energy. This work is inspired by carbon fixation, the set of chemical reactions that plants use to build sugars from carbon dioxide, using energy from the sun.

In the longer term, this approach could also be used to power micro- or nanoscale robots. Strano’s lab has already begun building robots at that scale, which could one day be used as diagnostic or environmental sensors. The idea of being able to scavenge energy from the environment to power these kinds of robots is appealing, he says.

“It means you don’t have to put the energy storage on board,” he says. “What we like about this mechanism is that you can take the energy, at least in part, from the environment.”

Asian companies claim they are going net-zero — but are their targets realistic, ambitious or greenwash?

Asian companies claim they are going net-zero — but are their targets realistic, ambitious or greenwash?

The race is on for the business world to figure out how to sustain economic growth and go carbon-free.

The penny seems to be dropping that avoiding climate action comes with financial risks. Last October, 200 of the world’s largest multinational companies said they would achieve net-zero carbon emissions by 2050. Among them were Asian companies in sin industries linked with spotty environmental records such as Sinopec and Asia Pacific Resources International Limited (APRIL). Chevron, Philip Morris and DuPont were also among those that made pledges.

By 2050, climate change will shrink the global economy by 3 per cent as drought, flooding, crop failure and infrastructure damage become more severe — unless drastic action is taken to bend the curve on global warming, according to a report by the Economist Intelligence Unit.

The Covid-19 pandemic — which has been called a “dress rehearsal” for climate change — has accelerated the urgency to mitigate the impacts of climate change which cost the global economy billions every year.

“Suddenly, corporates have realised that if we’re going for a 1.5 degrees Celsius cap on global warming [the goal of the Paris Agreement on climate change], we have to hit net zero by 2030. It’ll be very expensive to decarbonise any later,” said Malavika Bambawale, Asia Pacific head of sustainability solutions at Engie Impact, a decarbonisation consultancy.

 

“What is the cost of not decarbonising? That is the question businesses should really be asking themselves.”
Pratima Divgi, director, Hong Kong, Asean, Oceania, CDP

 

Western businesses have led the way, with the likes of Microsoft saying it will make “the biggest commitment in our history” by removing all of the carbon it has put into the atmosphere since its founding in 1975. Asian companies have been slower to commit. “A lot of Asian companies are further down the supply chain, so they can hide for longer,” says Bambawale.

But climate action in a region that produces more than half of global emissions is cranking up. Of the 1,200 or so firms that have signed up to the Science-Based Targets initiative (SBTi), which helps companies cut their emissions in line with the Paris Agreement, 250 Asian companies have set carbon-cutting targets or are in the process of getting targets approved — a 57 per cent increase between 2019 and 2020. Forty-eight of those 250 firms have aligned their business models with the Paris agreement. 

“From a small base, corporate decarbonisation is growing in Asia Pacific,” says Pratima Divgi, Hong Kong, Southeast Asia, Australia and New Zealand director at CDP, a carbon disclosure non-proft that co-developed the SBTi. Companies that have signed up to the SBTi include Hong Kong real estate firm Swire Properties, Chinese computer giant Lenovo, and Malaysian textile firm Tai Wah Garments Industry.

National-level policy commitments, like China, Korea and Japan’s net-zero declarations over the past six months have set the tone for Asian corporate decarbonisation. Competition is helping. Australian supermarket chain Coles declared a 2050 net zero target six months after rival Woolworths did the same, and Singaporean real estate firm City Developments Limited (CDL) made a net zero pledge the week after competitor Frasers Property. Gojek and Grab are racing to be the first ride-hailing app in Southeast Asia to declare a decarbonisation target.

“Now that market leaders such as CDL have made net-zero commitments, it will be harder for their competitors to sit and wait,” says Bambawale.

Malaysian oil and gas giant Petronas announced in October that it would hit net-zero by 2050, a month after PetroChina, the region’s largest oil company, said it would be “near-zero” by mid-century.

 

Aspiration versus reality

But questions hang over how Asia’s big-polluters will realise their declared targets. Ensuring the big emitters share detailed plans and a budget to support their carbon neutral declarations is key for accountability.

PetroChina’s announcement came with “frustratingly little detail”, commented renewables consultancy Wood MacKenzie. The oil giant aims to spend just 1-2 per cent of its total budget on renewable energy between now and 2025. This compares to Italian oil major Eni’s planned 20 per cent of total spend on renewables by 2023 and BP’s 33 per cent by 2030.

Petronas’ own 2050 net-zero pledge is an “aspiration” and not a science-based target that aligns the firm with the Paris Agreement.

“Aspirational targets can only go so far — science-based targets also need to clearly allocate interim short- to medium-term targets to work out what this transformation means to your business and value chain,” says Divgi.

Setting a science-based carbon reduction target takes time. Singapore-based transport firm ComfortDelGro has given itself two years to set science-based goals, but the company avoided giving a carbon reduction timeline in its announcement earlier this month.

Other companies are also being selective with the information they make public. This could be because they do not want to reveal the extent to which they intend on decarbonising, or because they do not have a plan yet. CDL has pledged that it will be net-zero by 2030 — 20 years ahead of competitor Frasers Property — but has declined to give further detail on how it will meet this target.

CDL’s carbon commitment is limited to its wholly-owned assets and developments under its direct control, while Frasers Property is aiming to remove emissions from its entire value chain.

 

Why carbon dieting is difficult

For major emitters like oil and gas firms, decarbonising means transforming their business model without going out of business. Petronas told Eco-Business that meeting its 2050 target “won’t be easy”, and would require the company to “re-strategise how we do our business, with the focus no longer being on profitability or production capacity alone”.

Petronas plans include hydrocarbon flaring and venting, developing low and zero carbon fuels, capturing emissions and investing in nature-based solutions. It also plans to cap emissions to 49.5 million tonnes of carbon dioxide-equivalent for its Malaysia operations by 2024, and increase renewable energy capacity to 3,000 megawatts by the same year.

Meeting its target would “requires us to strike an equitable balance between providing low carbon solutions while still ensuring energy security and business profitability,” said the company’s group health, safety, security and environment vice-president, Dzafri Sham Ahmad.

But removing the carbon from a company’s operations is no longer deemed enough. The indirect emissions that occur in the entire value chain — known as scope 3 emissions — are becoming the new business imperative. A new report from CDP found that emissions from a company’s supply chain are on average 11.4 times higher than its operational emissions – double previous estimates. ExxonMobil’s scope 3 emissions from the use of its products exceed the national annual emissions of Canada, it was revealed in January.

 

“Achieving this aspiration will require us to re-strategise how we do our business, with the focus no longer being on profitability or production capacity alone.”

Dzafri Sham Ahmad, vice-president, group health, safety, security and environment, Petronas

 

Electric vehicle makers such as Telsa are now asking questions about the emissions of their nickel suppliers while computer giant Apple wants to source low-carbon semiconductor chips. But tackling scope 3 emissions is tricky. For instance, how do Singapore construction companies reduce the imported carbon of building materials sourced from China, where electricity is generated from coal? And how does a building owner persuade its tenants to turn down the air-conditioning?

“Reducing scope 3 emissions looks easy enough from the top down. But for people in the field operating the assets it can be a nightmare,” says J. Sarvaiya, an engineer who’s an expert in decarbonisation.

Balancing the carbon books by sourcing renewable energy is also difficult in a region where fossil fuels are still the dominant power source, and where a diversity of regulatory landscapes has made scaling renewables hard and where prices remain high in places. This has led Asian companies to focus on reducing energy consumption first, before looking at procuring renewables, notes Bambawale.

But energy capping is not easy in a high-growth region with escalating energy needs. Southeast Asia’s energy consumption is growing by 4 per cent a year — twice the rate of the rest of the world — and much of that demand comes through cooling as global temperatures rise. Some 30 per cent of a business’s energy bill in this region goes on cooling, says Bambawale.

 

Offset or cut?

Facing so many challenges, it’s tempting for businesses to buy their way to net-zero. Carbon offsets, where companies fund projects that capture or store greenhouse gas emissions to offset their own, are becoming an increasingly popular path to carbon neutrality. Singapore state investor Temasek was one of Asia’s first companies to neutralise the carbon emissions of its operations last year, and did so primarily by buying carbon offsets. Petronas is also relying on offsets as part of its ‘measure, reduce, offset’ net-zero drive.

But offsets are drawing growing scepticism because they enable businesses to carry on as usual, without reducing their actual footprint. “Many companies find that it’s cheaper to reach net-zero by purchasing offsets. It may cost more to replace old technology with more efficient kit than buying offsets,” says Sarvaiya.

Offsets are a necessary piece of the decarbonisation puzzle — but the quality of offset is key, says Bambawale. Companies should ensure that an offset is additional—that is, the carbon reduction would not have happened without the company’s effort. It should also have permanent, rather than temporary, impact. And it should not cause any sort of environmental or social harm. Proving all of that is difficult. “Companies could spend years checking and validating that an offset is actually happening,” says Bambawale.

Offsets will get more problematic the warmer the world gets, Sarvaiya points out. The ability of plants to absorb carbon declines in a warmer world, so more trees will have to be planted to balance the carbon books. Buying renewable energy faces a similar issue. Every one degree increase of surface temperature reduces the efficiency of solar panels by 0.5 per cent.

Companies are also looking to emerging technologies to help them hit carbon goals. In Singapore, concrete producer Pan-United and Keppel Data Centres are part of a consortium that is banking on carbon capture, use and storage technology that won’t be online for another five to 10 years to reduce the carbon impact of the city-state’s oil refining, petrochemicals and chemicals sectors.

Heavy-emitting sectors such as steel production, aviation and shipping have high hopes for hydrogen power, which is considered the missing piece of the renewables puzzle. But questions over cost and transportation make hydrogen a fuel for the future for now. “Moonshot ideas should be the last step,” says Bambawale.

 

Why net-zero is not just hot air

In Southeast Asia, where governments have shown little interest in decarbonising their economies in their post-pandemic recovery plans, there is less incentive for businesses to cut their carbon footprints amid the struggle to stay afloat.

But a wave of commitments to decarbonisation in the past 18 months will likely lead to more. Scores of businesses have signed up for science-based targets during the pandemic, which has played a part in pushing others towards net-zero, says Divgi, adding that a Southeast Asian bank recently committed to SBTi whose suppliers’ emissions were 400 times its own.

Another indicator of interest in corporate climate action is the Task Force on Climate-Related Financial Disclosures (TCFD), a global framework for companies to disclose the financial risks they face from climate change. CDP has seen a 20 per cent increase in TCFD disclosures in Asia over the last year, Divgi notes.

More companies are trying to assess the financial implications of the transition to a low-carbon economy, and the more progressive companies have recognised that calculating climate risk is not a reporting exercise, it’s a strategic one, says Divgi.

“We’re not saying that it [decarbonising] is without problems. There’s a huge level of transformation involved, but climate change presents both a financial and an existential challenge for many businesses,” she says.

“What is the cost of not decarbonising — that is the question that businesses should really be asking themselves.”
