Aquifer Thermal Energy Storage for Renewables

Aquifer Thermal Energy Storage for Renewables

It’s Not All About Energy Generation

When the topic of decarbonization comes up, oftentimes, we think of transportation or energy generation. These issues are important, as vehicle emissions are a major problem, as well as emissions from fossil fuel power generation. However, while important, these issues only partially show the roadblocks to moving towards a green future.

Another component that needs to be addressed in the conversation is energy storage and efficiency in renewable energy.

Wind and solar energy are important and rapidly developing technologies but are dependent on weather conditions that vary from month to month and from year to year. In colder months, when houses need to heat, that is when significantly less sunlight is present, thus driving down the available energy to heat them.

This is why energy storage is crucial to the conversation regarding renewable energy, but other solutions might mitigate this problem if properly implemented. This is how aquifer thermal energy storage (ATES) could help assist in cooling and heating buildings, reducing the reliance on other renewable energy sources.

How About Aquifer Thermal Energy Storage?

Energy storage is a difficult topic to address, as the technologies required to implement large-scale grid energy storage require, ironically, a lot of energy. This isn’t helped by the fact that hydrogen energy storage systems right now lose a significant amount of the energy stored.

This is why reducing the grid energy demand is important to implement renewable energy systems successfully. Aquifer thermal energy storage is an interesting form of renewable energy specific to the heating and cooling of buildings because it ties in directly with the seasons that affect solar energy so much.

It works by utilizing two wells connected to the same groundwater reservoir. Cold groundwater is pumped up to cool the building during the summer, then stored. The same process happens in winter but in reverse. Warm groundwater is pumped up into the building, then stored.

Aquifer thermal energy storage systems can also store excess heat from industrial operations, similar to the geothermal systems being deployed in decommissioned oil wells. This process can help bridge the gap between the seasonal availability of renewable energy while at the same time decarbonizing the heating and cooling sector.

This system is also useful because it can make energy infrastructure more resilient by reducing the demand currently placed upon it by heating and cooling. According to a study in Science Direct, Aquifer thermal energy storage systems could reduce reliance on fossil fuels for energy by up to 40%.

New Tech can Help but not Solve Inherent Limits

The importance of renewable energy in the transition to a greener world cannot be understated. However, it is also important to recognize that there are limitations to the technology currently available.

Going forward, there are certainly ways that renewable energy, specifically solar, can become more efficient; the issue of seasonal availability will always be there. This is why alternative methods of addressing needs like heating and cooling are as important.

The issue of energy storage is also important because bridging the gap between availability and need is necessary for making renewable energy a viable alternative to our current fossil fuel energy generation system.

Kimberly-Clark firms up plans for three UK-based green hydrogen projects

Kimberly-Clark firms up plans for three UK-based green hydrogen projects

The firm, which owns brands such as Andrex and Huggies, is celebrating the fact that the project near Barrow-in-Furness was successful in securing a place on the UK Government’s Hydrogen Business Model Strategy Shortlist. The Shortlist was announced last week as part of a bumper day of green policy publications, detailing 20 projects set to share public funding support and benefit from streamlined planning processes.

Led by Carlton Power, the project is seeking to co-locate 35MW of electrolyser facilities and a 40MW energy storage system at the Cumberhead West Wind Farm. The 126MW wind farm is currently under construction and completion is expected later this year. Green hydrogen production should then be able to commence in 2025.

Kimberly-Clark is planning to offtake green hydrogen from the project to serve its paper mill in Cumbria, replacing natural gas. This plan was first announced to the general public in the summer of 2022, but the confirmation of Government support is a significant step forward.

Until the hydrogen production begins, Kimberly-Clark will offtake renewable electricity from the wind farm via a Power Purchase Agreement (PPA). It will use this electricity at three manufacturing sites and two distribution centres across the UK.

HYRO

Two additional green hydrogen projects involving Kimberly-Clark were also detailed on the UK Government’s Hydrogen Business Model Strategy Shortlist – one in Northfleet, Kent, and the other in Flint, North Wales.

Both of these projects are being led by HYRO, a joint venture between RES and Octopus Energy’s generation arm. HYRO’s long-term vision is to invest £3bn green hydrogen in the UK.

The two electrolyser projects will have a combined capacity of 22.5MW. As with the project in Cumbria, they will use renewable electricity to electrolyse water, thus producing green hydrogen. The hydrogen will be stored and fed into hydrogen-ready boilers within Kimberly Clark sites. A timeline has not yet been announced for the completion of the renewable arrays nor the electrolysers.

Kimberly-Clark’s managing director for the UK and Ireland, Dan Howells, said: “A lot of hard work has gone into developing the green hydrogen projects and it’s fantastic to see the UK government selecting them for the funding shortlist.

“These developments represent a significant stepping stone towards our big ambition to move solely to renewable energy to manufacture Andrex, Kleenex, Huggies, WypAll and Scott in the UK by 2030. We can only reach our decarbonization goals via innovative partnerships and cutting-edge technology.”

Other manufacturers exploring hydrogen as a natural gas replacement in the UK include Unilever, Pilkington Glass, Quorn Foods, Kelloggs, PepsiCo, Essity, Encirc and Jaguar Land Rover.

Schneider Electric moves forward on sustainability plan

Schneider Electric – a European multinational based in France that produces specialised digital automation and energy management solutions – has been making headway in the march of electricity use. All and all, it is part of a grand plan of sustainability for the company.

In a sustainability impact report covering the years 2021-2025, the company has laid out a number of targets which it hopes to achieve. Among these are the following: 80% green revenue; saving 800 million tonnes of CO2 emissions for its customers; having 1,000 top suppliers to reduce emissions by 50%; getting 50% of green material into its products; and having all of its packaging free from single-use plastic.

 

A new approach to PE

Lately, Schneider has been doubling down on its efforts.

Last month it introduced ‘Innovation at the Edge,’ in which it seeks to partner with, invest in and incubate start ups via its venture capital fund, SE Ventures. Pivoting on its strengths, the fund aims to address the problems of the future. As it said in a statement: “We know to solve the climate crisis the world must become more sustainable, digital and electric. We also know the technologies exist today, but we have to move faster. Therefore, we pursue combinations of climate technology that address this challenge, and initiatives and business models to speed their deployment.”

Another measure Schneider has adopted to spur sustainable transformation is its Industrial Digital Transformation Consulting and Deployment Service, itself launched just last week. The remit of this “specialised global service” is, according to a press release, “to help industrial enterprises achieve future-ready, innovative, sustainable, and effective end-to-end digital transformation.”

Among the areas in which it hopes to guide its clients are in discovery, diagnosis, strategy, design, implementation, and ongoing customer success.

According to Marc Fromager, SVP Industrial Automation Services, Schneider Electric: “Successful industrial digital transformation requires a global vision that is agile enough to support local neds. Successful programmes encompass efficiency, sustainability, and employee empowerment, underpinned by robust cybersecurity.

“What elevates Schneider Electric isn’t our unmatched combination of digital transformation experience across a myriad of industries, supported by our world-leading energy management and automation technology and software – all delivered by local experts with the full backing of our global teams.”

Made in America: A lithium supply chain for EV batteries

Made in America: A lithium supply chain for EV batteries

With the U.S. supplying 1 percent of the world’s lithium, there’s nowhere to go but up.

About 30 miles east of Reno, Nevada — past Tesla’s sprawling Gigafactory battery plant and the arid dusty grasslands of Northern Nevada — a startup is developing a large factory that could help unlock lithium, a key ingredient in electric vehicle batteries, from the earth.

The six-year-old company, Lilac Solutions, makes small white beads that can extract lithium from salty water deposits called brines, found around the world in places such as Argentina and Chile — and also Nevada and California. So-called ion-exchange beads are already used for various industrial applications such as cleaning water, but these are the first used for extracting lithium.

The U.S. is a bit player in the global lithium mining and processing game, dwarfed by other countries. The U.S. produces about 1 percent of the world’s lithium, while Australia, Chile, Argentina and China collectively produce over 90 percent. For decades, the only lithium that trickled out of the U.S. came from a small mine in Nevada run by chemical company Albemarle.

But as global sales of EVs have begun to rise dramatically — expected to grow from just under 10 percent of new passenger vehicle sales in 2021 to 23 percent by 2025 — lithium demand has gone through the roof. The global demand for lithium is expected to rise from 500,000 metric tons of lithium carbonate equivalent in 2021 to 3 to 4 million metric tons by 2030. The problem is clear: Relying on other countries for essentially all the critical minerals that make up EV batteries is not just a liability, it’s a missed opportunity.

That’s why a collective effort is underway to shift the tectonic plates under the world’s lithium supply chain to include the U.S. Mining giants, automakers, tech startups, lithium speculators, state and local governments and the Biden administration have all been trying to kickstart America’s domestic lithium initiatives. New lithium projects, from mining to processing, are proposed across states including California, Nevada, North Carolina, Tennessee and Maine.

American automakers including General Motors, Tesla and Ford will need hundreds of thousands of tons of lithium to meet growing demand for lithium-ion-powered electric vehicles.
Earlier this month, President Joe Biden unveiled a plan to dole out close to $3 billion in grants to 20 companies that are manufacturing, processing or mining key minerals, including lithium, for electric vehicle batteries. Lilac Solutions was chosen to negotiate a $50 million grant to help build its planned factory in Fernley, Nevada, near Reno.

The Biden administration’s Department of Energy funding follows the newly established law, the Inflation Reduction Act, which ties some tax credits for electric vehicles to battery minerals that are extracted, processed or recycled in the U.S. This spring the administration also used the Defense Production Act to increase the American production of battery minerals.

While China, Australia, Chile, Argentina and others are likely to dominate the lithium supply chain for the foreseeable future, domestic U.S. sources for mining, processing and recycling lithium will be important to help bolster the emerging American EV industry.

 

Mine the brine

Lilac, founded in 2016 and based in Oakland, California, has been quietly attracting interest from mining partners such as Australia’s Lake Resources as well as big-name investors. Last year, the company closed on a $150 million round of series B funding from Bill Gates’ Breakthrough Energy Ventures and Chris Sacca’s Lowercarbon Capital. Lilac’s investors also include T. Rowe Price, MIT’s The Engine and Tesla backer Valor Equity Partners.

The startup has drawn a who’s who of funders because of its potential ability to unlock lithium from the world’s brines. Much of the current global lithium supply is dug out of hard rock in mines like in Australia. But there are untapped resources in salty water deposits, where the lithium exists in low concentration and the mixture has high impurities. Lilac says its beads can suck out the lithium from the solution and leave the rest of the brine mixture intact to be returned back to the environment.

The massive brine lithium mines of South America — found in places such as Chile’s Atacama desert — use huge amounts of water and land and take 12 to 18 months to produce lithium through solar evaporation. A technology like Lilac’s could offer a more efficient, more sustainable method across a much smaller footprint.

Part of Lilac’s Series B funding is being spent on getting the Fernley factory into production, Lilac CEO Dave Snydacker told GreenBiz last month. The $50 million from the DOE will help accelerate production, and the agency said Lilac’s funding will create 150 new jobs.

Snydacker said the plant will come online in phases over the next two years and eventually will be able to make enough beads to support the extraction of 200,000 tons per year of lithium. That’s the equivalent of close to half of the amount of lithium produced globally last year. The funding doesn’t just add to Lilac’s war chest, it also adds validation and the spotlight of the White House.

At the event where Biden unveiled the EV battery minerals grants, 10 executives of companies, many of them startups, appeared behind Biden on a screen and four made remarks about how the funding would be used. Three of the four speakers were leaders of lithium production and processing companies: Albemarle; American Battery Technology Company; and ICL-IP America.

Albemarle plans to use a $150 million grant from the DOE to build a lithium concentrator plant at a mine in Kings Mountain, North Carolina. A concentrator increases the amount of lithium per volume and is one step in the process to get it ready to put into batteries. When it’s up and running, the Kings Mountain lithium supply chain would be able to produce and process enough lithium for 750,000 electric cars per year.

It makes sense for U.S. companies to try to tap into domestic lithium when it’s done sustainably and in a sensitive way for local communities.
Albemarle is also doubling the size of its lithium mine, Silver Peak, in Nevada, about 200 miles southeast from Fernley and Tesla’s Gigafactory. In Nevada alone, there are 17,000 prospecting claims for lithium, the Guardian recently reported.

 

Long road for U.S. lithium

Becoming a player in the global lithium supply chain won’t be easy for U.S. stakeholders. Companies looking to build new mines or reopen older ones face lengthy environmental review processes and are often challenged by local Indigenous communities. And rightly so, mining companies have long histories of polluting lands and neglecting the needs of groups that might use the lands as sacred sites, communal purposes or for hunting and fishing.

Most of the domestic critical mineral deposits needed for EV batteries — lithium, cobalt, nickel, copper — are near Native American reservations. Lithium Americas Corp. has faced resistance from both Native American tribes and environmentalists over its proposed lithium mine, Thacker Pass, in Nevada. By some estimates, Thacker Pass could contain the largest hard rock lithium deposit in the U.S.

American automakers including General Motors, Tesla and Ford will need hundreds of thousands of tons of lithium to meet growing demand for lithium-ion-powered electric vehicles. The industry won’t be able to source all of that domestically and fast enough, and South American lithium mines are likely to play a key role in the growing American EV boom.

But it makes sense for U.S. companies to try to tap into domestic lithium when it’s done sustainably and in a sensitive way for local communities. Investors are eager to put money into U.S. lithium initiatives — it can be cheaper to finance U.S. projects versus international ones — and there are shipping efficiencies if mining, processing and battery production projects can all be on the same continent.

With America supplying just 1 percent of the world’s lithium, there’s nowhere to go but up when it comes to American-made and -processed lithium. And for Lilac Solutions, if the technology works economically at a commercial scale as its supporters hope it does, its Nevada factory could be a key way for an American-made tech to be the one to help unlock the world’s lithium.

Solar Blanket: Sustainable, Self-Sufficient Renewable Energy

Solar Blanket: Sustainable, Self-Sufficient Renewable Energy

Access to sustainable living and greener choices is still fairly limited to those that can afford to do so, often raising questions around inclusivity and accessibility in relation to sustainable, self-sufficient living.

If the aim is to move towards a greener future, including the widespread adoption of sustainable energy choices at both the macro and micro scale, the opportunity for everyone to access the renewable energy solution is absolutely vital.

A recent graduate of the MA Material Futures at Central Saint Martin’s (CSM), London, Mirielle Steinhage has conceived of a solar-powered blanket that could grant access to renewable energy to those in need. The blanket is made from a conductive material that can be used to warm a person using solar power as the energy source.

People Power
Steinhage was inspired to develop the project – People Power – as a way of making sustainable energy more accessible and by exploring ways in which to introduce people to affordable renewable energy products.

This is because often, there is an imbalance in the emphasis placed on individuals to take personal responsibility versus being able to access the resources to do so. This is far from the ideal scenario in a world trying to combat climate change.

This is where Steinhage’s ‘People Power’ could prove to be crucial, as it offers those living close or beneath the breadline access to technology that would benefit them in a practical scenario.

 

Cost Savings and Circularity
The energy-saving ‘Solar Blanket’ directs heat toward the user and isolates the warmth in their immediate periphery, which avoids wasting energy on heating up an entire space. Furthermore, the blanket could retail for around 10 GBP (roughly 12 USD), and as it is solar-powered, it does not incur any extra costs for charging either via a power supply or buying replacement batteries.

The solar panel which charges the blanket remains functional in almost all weather conditions and has been designed for easy positioning in front of a window. Currently, Steinhage has three low voltage prototypes, between 5 and 12 volts. The 12-volt blanket has the capacity to heat to around 30 degrees Celsius, and the power bank remains functional for two hours on a single full charge.

The blanket’s portable power bank has the potential to be used with other compatible objects in the home. Additionally, portability means that the blanket can be used in a wide range of scenarios and environments as it is not restricted to a single room.

Steinhage’s design is made from polyester fabric combined with a conductive yarn that helps generate heat. A polyester ribbon is also part of the fabrication to prevent any damage when the yarn comes into contact with itself when folded or in use.

Steinhage specifically chose these materials for their cost-effectiveness, functionality, and durability. Moreover, they can be easily separated for recycling, making the blanket a circular product that could be later converted into other useful products.

In the future, Steinhage is focused on developing more sustainable, self-sufficient renewable energy products that are accessible to all. She hopes she can extend the People Power range to include household lighting solutions and fans that would be compatible with the same solar panel and power bank.

Hornsea 2 offshore wind farm now fully operational, making it the world’s largest

Hornsea 2 offshore wind farm now fully operational, making it the world’s largest

Construction began at the 165-turbine project, 89km off the coast of Yorkshire, in 2018. Ørsted announced on Wednesday (31 August) that it is now fully operational.

The Dutch business now has 13 fully operational offshore wind farms in the UK that it either fully or partly owned, with a combined capacity of 6.2GW. Its other British projects include Hornsea 1, Walney and the Walney Extension, and Burbo Bank and the Burbo Bank Extension.

“The UK is truly a world leader in offshore wind and the completion of Hornsea 2 is a tremendous milestone for the offshore wind industry, not just in the UK but globally,” said Ørsted,’s head of region for the UK Duncan Clark.

 

 

 

“Current global events highlight more than ever the importance of landmark renewable energy projects like Hornsea 2, helping the UK increase the security and resilience of its energy supply and drive down costs for consumers by reducing dependence on expensive fossil fuels.”

To Clark’s point on cost, the Government is currently consulting on what it describes as the broadest plans for electricity market reform in a generation. Among the measures proposed in the Review of Electricity Market Agreements (REMA) are interventions to de-couple global gas prices from electricity prices. Prime Minister Boris Johnson spoke out in favour of change at last month’s G7 Summit in Germany.

In the UK, wholesale electricity prices are informed by gas prices, partly due to the historic and present extent of gas-fired generation in the energy mix. It has been pointed out that this is not fair on domestic and business customers who purchase 100% renewable energy. Under the latest CfD round, offshore wind operators will sell power for as little as £37.35 per MWh.

 

Offshore wind expansion

The UK is aiming to host 50GW of offshore wind by 2030 in contribution to its ambitions on net-zero emissions and energy security. This target was announced in April’s Energy Security Strategy, increasing the previous 40GW target set by Johnson through the Ten-Point Plan. The Strategy envisions 95% of the UK’s electricity mix being low-carbon by 2030, rising to 100% by 2035.

A further extension in the Hornsea zone is set to help deliver on the 50MW by 2030 goal. Last year, Ørsted received allocation through the Contracts for Difference (CfD) auction scheme for Hornsea 3, after the project received consent for development in December 2020. Up to 231 turbines will be installed for Hornsea 3 and Ørsted expects to commission the project in 2027. In total, the three Hornsea projects will have a combined capacity exceeding 5GW.

In the UK government’s latest CfD auction round in July, 11GW of renewable energy was commissioned in total. The lion’s share, as usual, went to offshore wind developers.

Crab and lobster shells could be used to make renewable batteries

Crab and lobster shells could be used to make renewable batteries

Scientists want to use a chemical found in crab and lobster shells to make batteries more sustainable, according to research.

“We think both biodegradability of material, or environmental impact, and the performance of the batteries are important for a product, which has the potential to be commercialised,” said Liangbing Hu, the director of the University of Maryland’s Center for Materials Innovation and lead author of the paper, published in the journal Matter.

As the world transitions towards deploying green energy solutions and electric vehicles, the batteries being used for such technology also need to be eco-friendly.

But the chemicals used in conventional batteries such as lithium-ion can take hundreds or thousands of years to break down. These chemicals are also often corrosive and flammable. In some cases consumer-gadget batteries have caught fire on aircrafts, or caused fires in waste and recycling sites.

The researchers in Maryland have developed batteries that use a product derived from crustacean shells to store energy.

Crustaceans such as crabs, shrimps and lobsters have exoskeletons made of cells that contain chitin, a kind of polysaccharide that makes their shells hard and resistant. This valuable material is abundant in nature and can also be found in fungi and insects, but is usually thrown away as food waste from restaurants and a byproduct of the food industry. Scientists have long been researching its various applications – in biomedical engineering, for example, for wound dressing as well as anti-inflammatory treatments – and now, electrical engineering.

Through chemical processing and adding acetic acid aqueous solution, chitin can ultimately be synthesized into a firm gel membrane and used as an electrolyte for a battery. An electrolyte is the liquid, paste, or gel inside a battery that helps ions – charged molecules – travel between one end and the other of a battery, allowing it to store energy.

By combining this chitosan electrolyte with zinc, a naturally occurring metal increasingly used to make batteries that are cheap and safe, Hu’s team was able to create a renewable battery.

The battery is 99.7% energy efficient even after 1,000 battery cycles, which is about 400 hours. This means they can be quickly charged and discharged without significantly affecting their performance. “It is not an easy thing for batteries to operate at high current density. The displayed performance suggests the merit of chitosan-based material in this work,” said Hu.

 

The batteries are not flammable and the two-thirds of the battery made of chitosan can break down in soil thanks to microbial degradation in just five months, leaving behind recyclable zinc. Antonio J Fernández Romero, a professor of material sciences for energy production at the University of Cartagena in Spain, who was not involved in the study, said these were “outstanding properties”.

He said: “The design of new batteries that are respectful of the environment, cheap and producing high discharge capacity, is one of the more important items that must be developed in the coming years.” He added that biodegradability was key, and at this level the system seemed to work very well but it would have to be tested on a larger scale and under commercial use conditions.

The design may pave the way for developing high-performance and sustainable batteries for green energy storage, according to Hu and the study authors.

“When you develop new materials for battery technologies there tends to be a significant gap between promising lab results and a demonstrable and scalable technology,” said Graham Newton, a professor of materials chemistry at the University of Nottingham, who was not involved in the study. He is an expert in sustainable batteries and researches how they can be improved.

So far, according to Newton, the chitosan-zinc battery results are promising. “There are some examples of batteries like this that have been commercialized and are being trialed as stationary energy storage systems,” said Newton. “There are still quite a few challenges to be met in the development of zinc ion batteries, but fundamental studies such as this are hugely important.”

Shell Oil Asks What Public Is Willing to Do to Reduce Emissions

Shell Oil Asks What Public Is Willing to Do to Reduce Emissions

Rep. Alexandria Ocasio-Cortez on Monday denounced the “audacity” of oil giant Shell after it waded into the global discussion about the climate crisis by asking members of the public what they would do to reduce carbon emissions.

“I’m willing to hold you accountable for lying about climate change for 30 years when you secretly knew the entire time that fossil fuels emissions would destroy our planet,” the New York Democrat and co-sponsor of the Green New Deal legislation replied.

 

 

In the poll it posted to Twitter, Shell offered choices to the public including “stop flying,” “buy an electric vehicle,” and shifting to renewable electricity.

 

 

Coming from the world’s third-largest company, which knew as early as 1988 that its extraction of oil and gas was linked to the heating of the planet, the question was seen by Ocasio-Cortez and other critics as a gross deflection of Shell’s own responsibility.

“The audacity of Shell asking YOU what YOU’RE willing to do to reduce emissions,” Ocasio-Cortez tweeted. “They’re showing you RIGHT HERE how the suggestion that individual choices—not systems—are a main driver of climate change is a fossil fuel talking point.”

The “good choices” American voters and lawmakers can make, the congresswoman added, are ones that will help “reign in fossil fuel corporations” that are actually fueling the destruction of the planet.

The journalism initiative Covering Climate Now called Shell’s tweet “a textbook example of greenwashing.”

Prof. Katharine Hayhoe, director of the Texas Tech Climate Center, echoed Ocasio-Cortez’s disgust at the company as she noted that out of 90 companies in the world, Shell is the sixth-highest contributor to fossil fuel emissions in history.

“Yes, everyone must do their part—starting with the biggest emitters,” Hayhoe tweeted, adding that the company has previously publicly suggested that individuals making changes to their daily habits is what will help save the planet.

 

 

Shell’s tweet drew outrage from international climate action group Greenpeace, international lawmakers, and climate experts.

 

 

 

 

“What am I willing to do?” Hayhoe wrote in reply to Shell’s poll question, which she later said was hidden on Twitter by the company. “Hold you accountable for 2% of cumulative global greenhouse gas emissions, equivalent to those of my entire home country of Canada. When you have a concrete plan to address that, I’d be happy to chat about what I’m doing to reduce my personal emissions.”
