Twiggy Forrest sets sights on making the impossible possible when it comes to ‘pure green energy’

Twiggy Forrest sets sights on making the impossible possible when it comes to ‘pure green energy’

In the second half of last year, while most of the world was in pandemic lockdown, Andrew “Twiggy” Forrest and a team of 50 staff did what others couldn’t. He spent five months crisscrossing the globe in a private jet, visiting more than 40 countries.

It set Australia’s second-richest person on a path to an outcome that, if delivered, could transform the energy landscape of not just Australia, but the globe.

The iron ore billionaire says after his private discussions with sovereign leaders, politicians, business people and investors across the world he was convinced of their “genuine thirst for our green energy”.

“It made me strongly, and no longer hesitantly, optimistic,” he told Guardian Australia. “I felt a change in the global mood, a shift in belief, that the impossible could be possible.”

Forrest’s response was to announce in November that his Fortescue Metals Group would aggressively support zero-emissions energy through its new green arm, Fortescue Future Industries.

The initial pledge was that it would back 235 gigawatts of clean energy capacity – more than three times the entire Australian electricity grid – across the globe, with $1bn committed over the next two years. Four months on, that has expanded to a promise to explore more than 500GW of hydro, geothermal, wind and solar with a goal of being involved in the creation of 1,000GW.

 

Forrest estimates the world will need at least 5,000GW of pure green energy to really slow the climate crisis. He has committed himself to helping develop a fifth of that by providing capital, technology and encouragement.

It will, he claims, “create so much momentum and value that consuming energy from a polluting source becomes commercial nonsense”. He has big-name support: the former Australian prime minister, Malcolm Turnbull, has signed on as chairman of the future industries arm, and the ex-Australian Secret Intelligence Service director general, Nick Warner, is a special advisor on international affairs.

“We figure if we are able to set an example of a 1,000GW target then people will realise that the impossible isn’t actually impossible,” Forrest. “We’re hoping that other companies will get in and vigorously compete with us, and maybe even challenge and beat us, but what will happen in that process is global warming will slow and eventually stop. That’s our mission.”

It is a pledge that sits alongside – and in some cases outstrips – support for fixing the climate crisis from some of the world’s richest people, including Elon Musk and Jeff Bezos. Like some of their commitments, it has drawn widespread praise for the agenda-setting and potentially transformative role it could play – and a fair dose of scepticism about whether it is possible.

Forrest’s green ambition is too vast to quickly summarise. In addition to the global push, which he says has already led to deals in 17 countries, FMG this month set a domestic target of reaching net zero emissions by 2030, a decade earlier than it had previously promised, and 20 years before most competitors.

Underpinning it is Forrest’s belief that green hydrogen, created using renewable energy, will change energy systems much faster than some analysts believe is possible. From there, he says, it can be used to create zero-emissions liquid green ammonia and turn iron ore into the holy grail of “green steel” – made without the current reliance on coking coal.

 

Some of his goals will be tested in the short-term. In a speech to a Credit Suisse investment conference on Wednesday, Forrest said that by 30 June this year the company will have developed a green iron ore train that either runs on renewable electricity or a combustion engine powered by green ammonia.

It also plans to be trialling a ship run on green ammonia, a shift that could lead to the replacement of the notoriously dirty bunker fuel currently used by fleets across the globe. Forrest says the pace of what he is proposing on shipping surprised and impressed the climate activist and former US vice-president, Al Gore, and puts him at least five years ahead of the global competition.

Dan Gocher, from shareholder activists the Australasian Centre for Corporate Responsibility, is among those impressed. He says Forrest’s vision for FMG is “literally decades ahead” of other major companies.

“They’re clearly the leading company on the Australian Stock Exchange in terms of ambition – and probably globally,” he said. “What he’s saying is what we’ve been calling on BHP and Rio [Tinto] to commit to – heavy investment in renewables to really kickstart the green hydrogen economy.”

While his focus is on a green future, Forrest has not completely abandoned fossil fuels – at least not yet. This week, he was also speaking with the federal and New South Wales energy ministers, Angus Taylor and Matt Kean, about a proposal by his private company, Squadron Energy, to build a new 635-megawatt gas-fired power station at Port Kembla.

If approved, it would initially run on liquefied natural gas (LNG) brought in via a new floating gas import terminal at the port. Forrest stresses both the plant and the terminal would be “dual-fuel” – a more expensive option that would give them the capacity to use green hydrogen once it is ready – but says he is making “an allowance for natural gas as a critical stepping-stone” to get the developments moving.

The continued inclusion of gas in Forrest’s portfolio has drawn criticism. Gocher says it is at odds with Forrest’s green ambition, which he believes FMG has the capacity to deliver.

“It is a bit hypocritical given the language he has used around the climate crisis,” Gocher said.

“He’s clearly saying we need to take action in the next 10 years, but he wants to build a terminal that will supply more gas. It means he’s not talking about electrification [of industry] or trying to reduce [gas] demand, which is what we should be talking about.”

Forrest takes umbrage when asked whether his gas developments are at odds with his climate push.

“If it was just a gas-fired power station and a gas importation system, sure, take me to task,” he said. “But if I’m spending the huge amount of capital to make it dual-fuel – that’s hundreds of millions – and then on the other side of my life [spending] tens of billions to create that green energy and green hydrogen, then the Guardian really has to be responsible, and encourage people to take that big step and build dual-fuel so that they can switch to hydrogen when it’s available.”

While the Morrison government has said it will back a “gas-led recovery” from recession, Forrest believes there is now no justification for leaders to support developments unless they also have the capacity to become zero emissions “when the fuel is available”.

“It might be green electricity, it might be green ammonia, it might be green hydrogen. If you really care for what your citizens want, make sure you’re not building a dinosaur or licensing a dinosaur.”

The bigger question about Forrest’s vision is whether the rise of green hydrogen is as inevitable as he believes.

The nascent technology is now receiving significant support across the globe, and the Morrison government has named it a priority under its low-emissions technology roadmap. But it is still early days – relatively little hydrogen from any source is being produced and less than 1% of that is created using renewable energy.

Tony Wood, the energy program director at the Grattan Institute, is among those who believe that while green hydrogen has a future, its ubiquity in a low-emissions world is not guaranteed. He doesn’t see a future for hydrogen-fuelled electricity, for example.

“There are better ways to produce low-emissions power than with hydrogen and if we could produce low-cost green hydrogen there are better uses for it than electricity,” he said.

Singapore renewable energy finance firm Positive Energy scales back as Covid stymies investment

Singapore renewable energy finance firm Positive Energy scales back as Covid stymies investment

The startup endured a tough 2020, shed staff and its co-founder relocated to the Netherlands as the firm’s only remaining employee. The startup’s struggles reflect the difficulties of renewables entrepreneurship in the Covid era.

Singapore-based renewable energy financing company Positive Energy has scaled back operations after enduring a difficult year impacted by the Covid-19 pandemic.

Positive Energy is a digital platform that connects renewable energy projects to investors, and aims to simplify and speed-up renewable energy project financing. Founded in 2017, the Asia-focused firm makes money by taking a cut of deals made on its platform.

Having raised seed funding and launched the platform in 2019, the firm ran into difficulties after failing to secure further financing in 2020. The platform was suspended late last year, and the company let go employees in Singapore, where it was headquartered, as well as business heads in Vietnam and India.

Co-founder and chief finance officer Vincent Bakker joined another firm at the start of this year. Co-founder and chief executive Nicolas Payen is now the sole employee, and has relocated from Singapore to the Netherlands.

Positive Energy recently landed a waste-to-energy deal that saved the company, and the platform is up and running again, Payen told Eco-Business.

Positive Energy is not the only player in the renewables space to face difficulties over the last year. The pandemic has applied the brakes to development capital, and investors have pulled back in emerging markets, meaning fewer potential deals to run on Positive Energy’s platform. The Covid-induced fall in electricity demand has also slowed the planning and execution of energy deals.

Payen said that although 2021 still presented uncertainties, if Covid vaccinations are rolled out quickly, a return to peak energy demand would follow, and that would mean a need for additional clean energy generation and investment.

“We have seen a number of countries declare net zero ambitions, and a lot of investment will be oriented towards climate friendly technology. So the fundamentals of our business are very strong,” he said.

“We will see growing momentum among climate technology venture capitalists this year. If we get the capital support we need, we can play our role in the energy transition.”

Payen said he remained focused on the company’s mission — rethinking the energy funding process to accelerate the deployment of renewable energy assets globally.

IEA: Renewables Will Lead Global Generation in 2025

IEA: Renewables Will Lead Global Generation in 2025

The world’s power generation is about to become even more green, according to a new publication from the International Energy Agency (IEA).

The group on Nov. 10 published its “Renewables 2020″ report, and highlighted how generation capacity from both wind and solar will double across the next five years and surpass global generation from both coal and natural gas. The IEA said renewable energy this year is growing at its fastest annual pace in the past six years, despite the COVID-19 pandemic. The agency said the pandemic has in fact hastened the closure of older thermal power generation infrastructure; as an example, American Electric Power this week announced it would shut down nearly half its entire fleet of U.S. coal-fired power plants.

The IEA in the report said “the COVID-19 crisis is hurting—but not halting—global renewable energy growth,” noting that “renewable markets, especially electricity-generating technologies, have already shown their resilience to the crisis.”

 

90% of New Generation Is Renewable

“From January to October 2020, auctioned renewable capacity was 15% higher than for the same period last year, a new record,” the report said. “At the same time, the shares of publicly listed renewable equipment manufacturers and project developers have been outperforming most major stock market indices and the overall energy sector.”

The report said almost 90% of new power generation in 2020 will be renewable, with about 10% of new output coming from natural gas- and coal-fired plants. The IEA said a continuance of that trend would make renewables the world’s largest power source in 2025.

Fatih Birol, the agency’s executive director, in a statement, said, “Renewable power is defying the difficulties caused by the pandemic, showing robust growth while other fuels struggle. The resilience and positive prospects of the sector are clearly reflected by continued strong appetite from investors—and the future looks even brighter with new capacity additions on course to set fresh records this year and next.”

Birol continued: “Governments can tackle these issues to help bring about a sustainable recovery and accelerate clean energy transitions. In the United States, for instance, if the proposed clean electricity policies of the next U.S. administration are implemented, they could lead to much more rapid deployment of solar PV [photovoltaic] and wind, contributing to faster decarbonization of the power sector.”

John Lichtenberger, senior vice president of Core Solar, an Austin, Texas-based developer of solar power projects, recently told POWER, “the cost of solar technology has come down so much” that developing solar power is a “no-brainer, from an environmental standpoint and an economic standpoint. Renewables are not a novelty, they’re a legitimate cost-effective, environmental way to generate power. Solar technology [has] been refined and improved, and the cost has come down. The technology has become a commodity, [and] we’re seeing production across the globe.”

 

Global Energy Demand Falls

The IEA said the coronavirus pandemic is a major factor in a 5% decline this year in global demand for energy. The report, though, said “priority access to the grid and continuous installation of new plants are all underpinning strong growth in renewable electricity. This more than compensates for declines in bioenergy for industry and biofuels for transport—mostly the result of lower economic activity. The net result is an overall increase of 1% in renewable energy demand in 2020.”

The report said new deployments of renewable energy, led by China and the U.S., mean that “net installed renewable capacity will grow by nearly 4% globally in 2020, reaching almost 200 GW. Higher additions of wind and hydropower are taking global renewable capacity additions to a new record this year, accounting for almost 90% of the increase in total power capacity worldwide. Solar PV growth is expected to remain stable as a faster expansion of utility-scale projects compensates for the decline in rooftop additions resulting from individuals and companies reprioritizing investments. Wind and solar PV additions are set to jump by 30% in both the People’s Republic of China and the United States as developers rush to complete projects before changes in policy take effect.”

The agency said India and the European Union also will drive increases in renewable energy, which the report said will result in a record expansion of global renewable capacity additions of nearly 10% next year, the fastest growth since 2015. The IEA recently said that solar power today is now the cheapest source of electricity in history.

The report said that total installed wind and solar PV capacity is on track to overtake natural gas in 2023, and coal in 2024—and said that generation from all renewable resources will become the “largest source of electricity generation worldwide in 2025,” supplying one-third of global power output.

The IEA report said, “Solar PV alone accounts for 60% of all renewable capacity additions through 2025, and wind provides another 30%. Driven by further cost declines, annual offshore wind additions are set to surge, accounting for one-fifth of the total wind annual market in 2025.”

Do you have an idea to make buildings part of the fight against climate change?

Do you have an idea to make buildings part of the fight against climate change?

The inaugural CapitaLand Sustainability X Challenge is searching the globe for the most innovative solutions to make buildings more climate-resilient and resource-efficient.

In less than a decade, 60 per cent of the global population will live in cities. How can the built environment innovate and adapt to accommodate 360 million more people projected to live in urban areas by 2030 and build within planetary boundaries?

On Tuesday (10 November), real estate group CapitaLand launched the inaugural CapitaLand Sustainability X Challenge, a global search for innovations to make buildings more climate-resilient and resource-efficient from their initial design to construction.

Launched in conjunction with CapitaLand’s 2030 Sustainability Master Plan, the innovation challenge will source for solutions to meet its new sustainability targets.

The challenge falls under four key themes that address important pain points of the built environment: low carbon transition, water conservation and resilience, waste management and the circular economy, and healthy and safe buildings.

“Through the CXSC, we are inviting individuals and companies worldwide to contribute their impactful and scalable innovations. We are also discussing with local and international organisations on opportunities to partner us for the challenge. We look forward to working with our partners and the participants to bring great ideas to life and to co-create a more sustainable built environment across the global communities we operate in,” said Lynette Leong, chief sustainability officer of CapitaLand Group.

“In addition to tackling the challenges of lowering carbon emissions and water conservation as well as promoting circularity in our waste management practices, threats such as Covid-19 and the haze have sharpened our focus on further improving the health and safety of our building occupants and customers, beginning with elevating the indoor air quality at our properties. This will reinforce our leading position as a sustainable global real estate company,” she added.

Two winners will be selected for the High Impact Award and Most Innovative Award, and will receive up to S$50,000 (US$37,200) in project funding and mentoring.

Winning submissions will be assessed based on the impact, potential outcomes, and depth of innovation. Other judging criteria include the solutions’ ability to be scaled and deployed across the different geographies and asset types of CapitaLand’s properties.

As well as prizes for the winners, other shortlisted participants will stand a chance to trial their innovations on selected CapitaLand properties.

Shortlisted teams will pitch their projects to a panel of judges at a finale event held in May 2021. The challenge is currently accepting submissions until 1 February 2021.

Ideas for CapitaLand Sustainability X Challenge can be submitted here.

Toshiba to end construction of new coal-fired power plants

Toshiba to end construction of new coal-fired power plants

Toshiba Corp. has said it will stop taking orders for new coal-fired power plants as it makes a wider push to embrace renewable energy, though it will still complete work on about 10 further facilities.

The engineering and technology giant will continue to manufacture steam turbines, offer maintenance services for existing coal-power plants and work on the construction of plants that have already been ordered.

The shift away from coal highlights differences between equipment suppliers as they move to leave the sector behind and focus on gas turbines and renewable energy.

Samsung C&T Corp. has faced criticism over its intention to complete further coal projects before quitting the fuel, while General Electric Co. said in September it will pursue an exit from its existing obligations.

The firms are under pressure amid investor demands for action on climate change and over the prospect that tighter government policy on greenhouse gas emissions will limit scope for new coal-fired plants — even in Asia, where nations currently remain reliant on the fuel as a form of cheap electricity generation.

“Demand for new coal-power plants has been dwindling,” Toshiba President Nobuaki Kurumatani said during a media briefing Wednesday. “We started considering withdrawing from new coal-plant construction in the previous fiscal year, and finally made the decision” after the government pledged last month to become greenhouse gas neutral by 2050.

Renewable energy-related investments in Japan could total as much as ¥80 trillion ($760.6 billion) over the next decade amid national efforts to lower emissions, Kurumatani estimated.

Toshiba has existing orders for the installation of coal-fired plant facilities in countries including Indonesia and India, according to details listed on its website.

Shares in the firm rose 0.8% in Tokyo trading on Wednesday. The company also released its second quarter earnings the same day, announcing an annual dividend forecast that beat analyst estimates.

Toshiba “needs to change strategy to take advantage of growth sectors,” wrote Llewelyn Hughes, an associate professor at the Australian National University’s Crawford School of Public Policy, in an email. “Toshiba is able to make this shift because it is a diversified company, so exiting coal is not existential for them.”

The company plans to invest ¥160 billion in renewable energy for its operations through the fiscal year ending March 2023, and also aims to halve carbon dioxide emissions by 2030, including so-called Scope 3 pollution, spokesman Takashi Ebina said Wednesday.

Toshiba aims to increase annual sales from its renewable energy business to ¥650 billion by March 2031, compared to about ¥190 billion in the most recent full year. Sales from thermal coal power and hydrogen businesses amounted to ¥222.5 billion in the year ended March 31, representing 6.6% of total sales.

When is solar tech more than an energy play? When it also helping tackle homelessness.

When is solar tech more than an energy play? When it also helping tackle homelessness.

An interview with Prasoon Kumar

 

 

What if solar panels not only powered homes – but also paid for them, too?

The company BillionBricks is building solar home communities (solar farms, with homes built underneath them) that can do just that.

BillionBricks CEO Prasoon Kumar says his company challenged themselves to build solar communities that “produce about 40 times more energy than what the community would consume,” and then “push that energy out into the grid.”

In this Impact Interview, we take a deep dive into BillionBrick’s mission to tackle the growing homelessness problem and provide sustainable housing innovations for a region that desperately needs them.

Super-charged: How Australia’s biggest renewables project will change the energy game

Super-charged: How Australia’s biggest renewables project will change the energy game

Australia doesn’t yet export renewable energy. But the writing is on the wall: demand for Australia’s fossil fuel exports is likely to dwindle soon, and we must replace it at massive scale.

The proposed Asian Renewable Energy Hub (AREH) will be a huge step forward. It would eventually comprise 26,000 megawatts (MW) of wind and solar energy, generated in Western Australia’s Pilbara region. Once complete, it would be Australia’s biggest renewable energy development, and potentially the largest of its type in the world.

Late last week, the federal government granted AREH “major project” status, meaning it will be fast-tracked through the approvals process. And in another significant step, the WA government this month gave environmental approval for the project’s first stage.

The mega-venture still faces sizeable challenges. But it promises to be a game-changer for Australia’s lucrative energy export business and will reshape the local renewables sector.

 

The projects promise enormous clean development opportunities for Australia’s north and will create thousands of jobs in Australia – especially in high-tech manufacturing.

 

Writing on the wall

Australia’s coal and gas exports have been growing for decades, and in 2019-20 reached almost A$110 billion. Much of this energy has fuelled Asia’s rapid growth. However, in recent weeks, two of Australia’s largest Asian energy markets announced big moves away from fossil fuels.

China adopted a target of net-zero greenhouse emissions by 2060. Japan will retire its fleet of old coal-fired generation by 2030, and will introduce legally binding targets to reach net-zero emissions by 2050.

There are signs other Asian nations are also moving. Singapore has weak climate targets, but on Monday inked a deal with Australia to cooperate on low-emissions technologies.

 

Export evolution

The Asian Renewable Energy Hub (AREH) would be built across 6,500 square kilometres in the East Pilbara. The first stage involves a 10,000MW wind farm plus 5,000MW of solar generation – which the federal government says would make it the world’s largest wind and solar electricity plant.

The first stage would be capable of generating 100 terawatt-hours of renewable electricity each year. That equates to about 40 per cent of Australia’s total electricity generation in 2019. AREH recently expanded its longer term plans to 26,000MW.

The project is backed by a consortium of global renewables developers. Most energy from AREH will be used to produce green hydrogen and ammonia to be used both domestically, and for shipping to export markets. Some energy from AREH will also be exported as electricity, carried by an undersea electrical cable.

Another Australian project is also seeking to export renewable power to Asia. The 10-gigawatt Sun Cable project, backed by tech entrepreneur Mike Cannon-Brookes, involves a solar farm across 15,000 hectares near Tennant Creek, in the Northern Territory. Power generated will supply Darwin and be exported to Singapore via a 3,800km electrical cable along the sea floor.

The export markets for both AREH and Sun Cable are there. For example, both South Korea and Japan have indicated strong interest in Australia’s green hydrogen to decarbonise their economies and secure energy supplies.

But we should not underestimate the obstacles standing in the way of the projects. Both will require massive investment. Sun Cable, for example, will cost an estimated A$20 billion to build. The Asian Renewable Energy Hub will reportedly require as much as A$50 billion.

The projects are also at the cutting edge of technology, in terms of the assembly of the solar array, the wind turbines and batteries. Transport of hydrogen by ship is still at the pilot stage, and commercially unproven. And the projects must navigate complex approvals and regulatory processes, in both Australia and Asia.

But the projects have good strategic leadership, and a clear mission to put Australian green energy exports on the map.

 

Shifting winds

Together, the AREH and Sun Cable projects do not yet make a trend. But they clearly indicate a shift in mindset on the part of investors.

The projects promise enormous clean development opportunities for Australia’s north, and will create thousands of jobs in Australia – especially in high-tech manufacturing. As we look to rebuild the economy after the Covid-19 pandemic, such stimulus will be key. All up, AREH is expected to support more than 20,000 jobs during a decade of construction, and 3,000 jobs when fully operating.

To make smart policies and investments, the federal government must have a clear view of the future global economy. Patterns of energy consumption in Asia are shifting away from fossil fuels, and Australia’s exports must move with them.

Australian outback cattle station to house world’s largest solar farm, powering Singapore

Australian outback cattle station to house world’s largest solar farm, powering Singapore

A cattle station halfway between Alice Springs and Darwin is set to house the world’s largest solar farm, with energy generated from the project to ultimately power Singapore.

Newcastle Waters, where casino mogul James Packer worked as a jackaroo for a year when his father, Kerry, owned the 10,000 sq km property, has been earmarked for the $20bn solar farm, according to the company responsible for the project, Sun Cable.

The 10-gigawatt solar farm, which will be visible from space if built, was granted major project status from the Morrison government in July and has attracted billionaire investors including Andrew Forrest and Mike Cannon-Brookes.

Sun Cable’s chief executive, David Griffin, told Guardian Australia the site would take up about 12,000 hectares, and that a referral for the project has been submitted to the Northern Territory’s Environmental Protection Authority – the first stage of a lengthy approvals process that is expected to allow construction to begin in late 2023, energy production by 2026 and export by 2027.

Speaking about the reasons for proposing the Newcastle Waters site, Griffin said its location was “a meeting point of a few key criteria”.

“It’s on the Adelaide to Darwin rail corridor, which is brilliant for our logistics given the enormous amount of material we’ll have to transport to the site,” he said. It was also within 30km of the Stuart highway, the main highway running through the sparsely populated Northern Territory.

“It’s a bit of a balancing act too, because it’s far south enough to get away from the main patch affected by the wet season, so it’s a steady solar resource throughout the year,” he said. “There’s plenty of sun and not many clouds.”

Griffin also said the site was not so far south that it made the costs of transmitting the electricity to Darwin too high, and that the existing land was “really ideal for construction of a solar farm as it’s extremely flat”.

Sun Cable has entered into an agreement with the current owners of Newcastle Waters, Consolidated Pastoral Company, to use the land. However, Griffin said he could not reveal the financial details of the deal.

Overhead transmission lines will send the electricity generated by Sun Cable to Darwin and feed into the state’s power grid, but Griffin said two-thirds of the power would be exported to Singapore by high-voltage direct current undersea cables.

There will be at least two cables, each with a diameter slightly smaller than a soccer ball, with Sun Cable able to provide about a fifth of Singapore’s electricity needs as the country looks to move away from its increasingly expensive gas-fired power system.

 

 

Griffin has also said the solar farm could supply power to remote communities in the Northern Territory that currently rely on expensive diesel generators for electricity.

Sun Cable expects the project will generate 1,500 direct jobs and 10,000 indirect jobs during construction, and about 350 permanent jobs once in operation.

Griffin said Sun Cable was working on a training and employment opportunities plan so part of the workforce could be sourced from nearby Indigenous communities, and that supplies would be produced by local businesses.

Exporting solar energy has been flagged as a way Australia can expand its energy production while significantly reducing global emissions. Australia is responsible for about 1.4% of greenhouse gas emissions, which increases by 5% if fossil fuel exports are counted.

Superconductors: Material raises hope of energy revolution

Superconductors: Material raises hope of energy revolution

Scientists have found the first material that displays a much sought-after property at room temperature.

It is superconducting, which means electrical current flows through it with perfect efficiency – with no energy wasted as heat.

At the moment, a lot of the energy we produce is lost as heat because of electrical resistance.

So room temperature “superconducting” materials could revolutionise the electrical grid.

Until this point, achieving superconductivity has required cooling materials to very low temperatures. When the property was discovered in 1911, it was found only at close to the temperature known as absolute zero (-273.15C).

Since then, physicists have found materials that superconduct at higher – but still very cold – temperatures.

The team behind this latest discovery says it’s a major advance in a search that has already gone on for a century.

“Because of the limits of low temperature, materials with such extraordinary properties have not quite transformed the world in the way that many might have imagined,” said Dr Ranga Dias, from the University of Rochester, in New York State.

“However, our discovery will break down these barriers and open the door to many potential applications.”

Dr Dias added that room temperature superconductors “can definitely change the world as we know it”.

In the US, electrical grids lose more than 5% of their energy through the process of transmission. So tackling this loss could potentially save billions of dollars and have an effect on the climate.

The scientists observed the superconducting behaviour in a carbonaceous sulphur hydride compound at a temperature of 15C.

However, the property only appeared at extremely high pressures of 267 billion pascals – about a million times higher than typical tyre pressure. This obviously limits its practical usefulness.

So Dr Dias says the next goal will be to find ways to create room temperature superconductors at lower pressures, so they will be economical to produce in greater volume.

These materials could have many other applications. These include a new way to propel levitated trains – like the Maglev trains that “float” above the track in Japan and Shanghai, China. Magnetic levitation is a feature of some superconducting materials.

Another application would be faster, more efficient electronics.

“With this kind of technology, you can take society into a superconducting society where you’ll never need things like batteries again,” said co-author Ashkan Salamat of the University of Nevada, Las Vegas.
