Proton Conducting Fuel Cells enable reversible hydrogen energy storage, coupling electrolyzers and fuel cells with ceramic catalysts and proton-conducting membranes to convert wind and solar electricity into fuel and back to reliable grid power.

Key Points

Proton conducting fuel cells store renewable power as hydrogen and generate electricity using reversible catalysts.

✅ Reversible electrolysis and fuel-cell operation in one device

✅ Ceramic air electrodes hit up to 98% splitting efficiency

✅ Scalable path to low-cost grid energy storage with hydrogen

If we want a shot at transitioning to renewable energy, we’ll need one crucial thing: technologies that can convert electricity from wind, sun, and even electricity from raindrops into a chemical fuel for storage and vice versa. Commercial devices that do this exist, but most are costly and perform only half of the equation. Now, researchers have created lab-scale gadgets that do both jobs. If larger versions work as well, they would help make it possible—or at least more affordable—to run the world on renewables.

The market for such technologies has grown along with renewables: In 2007, solar and wind provided just 0.8% of all power in the United States; in 2017, that number was 8%, according to the U.S. Energy Information Administration. But the demand for electricity often doesn’t match the supply from solar and wind, a key reason why the U.S. grid isn't 100% renewable today. In sunny California, for example, solar panels regularly produce more power than needed in the middle of the day, but none at night, after most workers and students return home.

Some utilities are beginning to install massive banks of cheaper solar batteries in hopes of storing excess energy and evening out the balance sheet. But batteries are costly and store only enough energy to back up the grid for a few hours at most. Another option is to store the energy by converting it into hydrogen fuel. Devices called electrolyzers do this by using electricity—ideally from solar and wind power—to split water into oxygen and hydrogen gas, a carbon-free fuel. A second set of devices called fuel cells can then convert that hydrogen back to electricity to power cars, trucks, and buses, or to feed it to the grid.

But commercial electrolyzers and fuel cells use different catalysts to speed up the two reactions, meaning a single device can’t do both jobs. To get around this, researchers have been experimenting with a newer type of fuel cell, called a proton conducting fuel cell (PCFC), which can make fuel or convert it back into electricity using just one set of catalysts.

PCFCs consist of two electrodes separated by a membrane that allows protons across. At the first electrode, known as the air electrode, steam and electricity are fed into a ceramic catalyst, which splits the steam’s water molecules into positively charged hydrogen ions (protons), electrons, and oxygen molecules. The electrons travel through an external wire to the second electrode—the fuel electrode—where they meet up with the protons that crossed through the membrane. There, a nickel-based catalyst stitches them together to make hydrogen gas (H2). In previous PCFCs, the nickel catalysts performed well, but the ceramic catalysts were inefficient, using less than 70% of the electricity to split the water molecules. Much of the energy was lost as heat.

Now, two research teams have made key strides in improving this efficiency, and a new fuel cell concept brings biological design ideas into the mix. They both focused on making improvements to the air electrode, because the nickel-based fuel electrode did a good enough job. In January, researchers led by chemist Sossina Haile at Northwestern University in Evanston, Illinois, reported in Energy & Environmental Science that they came up with a fuel electrode made from a ceramic alloy containing six elements that harnessed 76% of its electricity to split water molecules. And in today’s issue of Nature Energy, Ryan O’Hayre, a chemist at the Colorado School of Mines in Golden, reports that his team has done one better. Their ceramic alloy electrode, made up of five elements, harnesses as much as 98% of the energy it’s fed to split water.

When both teams run their setups in reverse, the fuel electrode splits H2 molecules into protons and electrons. The electrons travel through an external wire to the air electrode—providing electricity to power devices. When they reach the electrode, they combine with oxygen from the air and protons that crossed back over the membrane to produce water.

The O’Hayre group’s latest work is “impressive,” Haile says. “The electricity you are putting in is making H2 and not heating up your system. They did a really good job with that.” Still, she cautions, both her new device and the one from the O’Hayre lab are small laboratory demonstrations. For the technology to have a societal impact, researchers will need to scale up the button-size devices, a process that typically reduces performance. If engineers can make that happen, the cost of storing renewable energy could drop precipitously, thereby moving us closer to cheap abundant electricity at scale, helping utilities do away with their dependence on fossil fuels.

France Electricity Pricing Mechanism aligns with EU rules, leveraging nuclear energy and EDF profits, avoiding Contracts for Difference, redistributing windfalls to industry and households, targeting €70/MWh amid electricity market reform and Brussels oversight.

Key Points

A framework to keep power near €70/MWh by reclaiming EDF windfalls and redistributing them under EU market rules.

✅ Targets average price near €70/MWh from 2026

✅ Skims EDF profits above €78-80 and €110/MWh thresholds

✅ Aligns with EU rules; avoids nuclear CfDs and state aid clashes

France has unveiled a new electricity pricing mechanism, hoping to defuse months of tension over energy subsidies with Brussels and its neighbors.

The strain has included a Franco-German fight over EU electricity reform with Germany accusing France of wanting to subsidize its industry via artificially low energy prices, while Paris maintained it should have the right to make the most of its relatively cheap nuclear energy. That fight has now been settled.

On Tuesday, the French government presented a new mechanism — complex, and still-to-be-detailed — to bring the average price of electricity closer to €70 per megawatt hour (MWh) as of 2026, amid Europe's electricity market revamp efforts.

"The agreement has been defined to comply with European rules and avoid difficulties with the European Commission," said France's Economy and Finance Minister Bruno Le Maire, noting that France had ruled out other "simpler" options that would have caused tension with Brussels.

For example, France has not yet envisaged the use of state-backed investment schemes called Contracts for Difference (CfD), which were the main source of discord in talks with Germany on the electricity market reform and the EU push for more fixed-price contracts in generation. The compromise agreed by EU ministers last month gives the Commission the power to monitor CfDs in the nuclear sector.

"France wanted to limit as much as possible the European Commission's nuisance power," said Phuc-Vinh Nguyen, an energy expert at the Jacques Delors Institute think tank in Paris.

The announcement came weeks after French President Emmanuel Macron promised that France would "take back control" of its electricity prices to allow its industry to make the most of the country's relatively cheap nuclear energy.

Germany, by contrast, has moved to support energy-intensive industries with an industrial electricity subsidy, underscoring the policy divergence.

“The price of electricity has always been a major competitive advantage for the French nation, and it must remain so,” Le Maire said.

Under the new mechanism, part of a broader deal on electricity prices between the state and EDF, the government will seize EDF profits above certain thresholds and redistribute them directly to industry and households to bring prices closer to the desired level. Specifically, the government will redistribute 50 percent of EDF’s additional profits if prices rise above €78-€80 per MWh, and 90 percent of extra profits if prices rise above €110 per MWh.

The move also marks a new step in the government's power grab at EDF, after the company was fully nationalized earlier this year.

For years, France has been discussing an EDF reform with the Commission in order to address concerns by Brussels regarding disguised state aid to the company. In particular, the Commission wanted assurances that any state aid given to nuclear would be kept separate from those parts of the business subject to competition, such as renewable energy development.

An economy ministry official close to Le Maire argued that the new pricing mechanism would settle matters with Brussels on that front. A Commission spokesperson said Brussels was in contact with France on the file, but declined further comment.

The mechanism will replace the existing EU-mandated energy pricing mechanism, dubbed ARENH, which was set to expire at the end of 2025, and which has forced EDF to sell some of its electricity to competitors at a fixed low price since 2010, and comes amid contested electricity market reforms at EU level.

The new system could benefit EDF because it won't be bound to sell energy at a lower price, but instead will be allowed to auction off its energy to competitors. On the other hand, the redistribution system would deprive the company of some profits when electricity prices are higher. No wonder, then, that negotiations between the government and EDF have been "difficult," as Le Maire put it.

Ukraine Winter Energy Strategy strengthens the power grid through infrastructure repairs, electricity imports, renewable integration, nuclear output, and conservation to ensure reliable heating, blackout mitigation, and grid resilience with international aid, generators, and transmission lines.

Key Points

A wartime plan to stabilize Ukraine's grid via repairs, imports, renewables, and nuclear to deliver reliable electricity.

✅ Repairs, imports, and demand management stabilize the grid.

✅ Renewables and nuclear reduce outage risks in winter.

✅ International aid supplies transformers, generators, expertise.

As Ukraine braces for the winter months, the question of how the country will keep the lights on has become a pressing concern, as the country fights to keep the lights on amid ongoing strikes. The ongoing war with Russia has severely disrupted Ukraine's energy infrastructure, leading to widespread damage to power plants, transmission lines, and other critical energy facilities. Despite these challenges, Ukraine has been working tirelessly to maintain its energy supply during the cold winter months, which are essential not only for heating but also for the functioning of homes, businesses, hospitals, and schools. Here's a closer look at the steps Ukraine is taking to keep the lights on this winter and ensure that its people have access to reliable electricity.

1. Repairing Damaged Infrastructure

One of the most immediate concerns for Ukraine's energy sector is the extensive damage inflicted on its power infrastructure by Russian missile and drone attacks. Since the war began in 2022, Ukraine has faced repeated attacks targeting power plants, substations, and power lines, including strikes on western regions that caused widespread outages across communities. These attacks have left parts of the country with intermittent or no electricity, and repairing the damage has been a monumental task.

However, Ukraine has made significant progress in restoring its energy infrastructure. Government agencies and energy companies have been working around the clock to repair power plants and transmission networks. Teams of technicians and engineers have been deployed to restore power to areas that have been hardest hit by Russian attacks, often under difficult and dangerous conditions. While some areas may continue to face outages, efforts to rebuild the energy grid are ongoing, with the government prioritizing critical infrastructure to ensure that hospitals, military facilities, and essential services have access to power.

2. Energy Efficiency and Conservation Measures

To cope with reduced energy availability and avoid overloading the grid, Ukrainian authorities have been encouraging energy efficiency and conservation measures. These efforts are particularly important during the winter when demand for electricity and heating is at its peak.

The government has implemented energy-saving programs, urging citizens and businesses to reduce their consumption and adopt new energy solutions that can be deployed quickly. Measures include limiting electricity use during peak hours, setting thermostats lower in homes and businesses, and encouraging the use of energy-efficient appliances. Ukrainian officials have also been promoting public awareness campaigns to educate people about the importance of energy conservation, which is crucial to avoid grid overload and ensure the distribution of power across the country.

3. Importing Energy from Abroad

To supplement domestic energy production, Ukraine has been working to secure electricity imports from neighboring countries. Ukraine has long been interconnected with energy grids in countries such as Poland, Slovakia, and Hungary, which allows it to import electricity during times of shortage. In recent months, Ukraine has ramped up efforts to strengthen these connections, ensuring that it can import electricity when domestic production is insufficient to meet demand, and in a notable instance, helped Spain during blackouts through coordinated cross-border support.

While electricity imports from neighboring countries provide a temporary solution, this is not without its challenges. The cost of importing electricity can be high, and the country’s ability to import large amounts of power depends on the availability of energy in neighboring nations; officials say there are electricity reserves and no scheduled outages if strikes do not resume. Ukraine has been actively seeking new energy partnerships and working with international organizations to secure access to electricity, including exploring the potential for importing energy from the European Union.

4. Harnessing Renewable Energy Sources

Another key part of Ukraine's strategy to keep the lights on this winter is tapping into renewable energy sources, particularly wind and solar power. While Ukraine’s energy sector has historically been dependent on fossil fuels, the country has been making strides in integrating renewable energy into its grid. Solar and wind energy are particularly useful in supplementing the national grid, especially during the winter months when demand is high.

Renewable energy sources are less vulnerable to missile strikes compared to traditional power plants, making them an attractive option for Ukraine's energy strategy. Although renewable energy currently represents a smaller portion of Ukraine’s overall energy mix, its contribution is expected to increase as the country invests more in clean energy infrastructure. In addition to reducing dependence on fossil fuels, this shift is aligned with Ukraine’s broader environmental goals and will be important for the long-term sustainability of its energy sector.

5. International Aid and Support

International support has been crucial in helping Ukraine keep the lights on during the war. Western allies, including the European Union and the United States, have provided financial assistance, technical expertise, and equipment to help restore the energy infrastructure, though Washington recently ended some grid restoration support as priorities shifted. In addition to rebuilding power plants and transmission lines, Ukraine has received advanced energy technologies and materials to strengthen its energy security.

The U.S. has sent electrical transformers, backup generators, and other essential equipment to help Ukraine restore its energy grid. The European Union has also provided both financial and technical assistance, supporting Ukraine’s efforts to integrate more renewable energy into its grid and enhancing the country’s ability to import electricity from neighboring states.

6. The Role of Nuclear Energy

Ukraine’s nuclear energy plants play a critical role in the country’s electricity supply. Before the war, nuclear power accounted for around 50% of Ukraine’s total electricity generation, and for communities near the front line, electricity is civilization that depends on reliable baseload. Despite the ongoing conflict, Ukrainian nuclear plants have remained operational, though they face heightened security risks due to the proximity of active combat zones.

In the winter months, nuclear plants are expected to continue providing a significant portion of Ukraine's electricity, which is essential for meeting the country's heating and power needs. The government has made efforts to ensure the safety and security of these plants, which remain a vital part of the country's energy strategy.

Keeping the lights on in Ukraine during the winter of 2024 is no small feat, given the war-related damage to energy infrastructure, rising energy demands, and ongoing security risks. However, the Ukrainian government has taken proactive steps to address these challenges, including repairing critical infrastructure, importing energy from neighboring countries, promoting energy efficiency, and expanding renewable energy sources. International aid and the continued operation of nuclear plants also play a vital role in ensuring a reliable energy supply. While challenges remain, Ukraine’s resilience and determination to overcome its energy crisis are clear, and the country is doing everything it can to keep the lights on through this difficult winter.

Romania Ends CGN Cernavoda Nuclear Deal, as Nuclearelectrica moves to terminate negotiations on reactors 3 and 4, citing the EU Green Deal, US partnership, NATO, and a shift to alternative nuclear capacity options.

Key Points

Romania orders Nuclearelectrica to end CGN talks on Cernavoda units 3-4 and pursue alternative nuclear options.

✅ Negotiations on Cernavoda units 3-4 to be formally terminated

✅ EU Green Deal and US partnership cited over security concerns

✅ Board to draft strategies for new domestic nuclear capacity

Romania's government has mandated the managing board of local nuclear power producer Nuclearelectrica to initiate procedures for terminating negotiations with China General Nuclear Power Group (CGN) on building two new reactors at the Cernavoda nuclear power plant, where IAEA safety reports continue to shape operations.

The government also mandated the managing board to analyse and draw up strategic options on the construction of new electricity generation capacities from nuclear sources, as other countries such as India take steps to get nuclear back on track in response to demand.

The company will negotiate the termination of the agreement signed in 2015 for developing and operating units 3 and 4 at Cernavoda, even as Germany turns away from nuclear within the European landscape. 

At the end of last month, Economy Minister Virgil Popescu said that the collaboration with the Chinese company couldn't continue as it has yielded no results in seven years, despite China's nuclear program expanding steadily elsewhere.

"We have a strategic partnership with the US, and we hold on to it, we respect our partners. We are members of the EU and Nato, even as Germany's final reactor closures unfold in Europe. Aside from that, I think that seven years since this collaboration with the Chinese company began is enough to realise that we can't move on," Popescu said at that time.

Liberal Prime Minister Ludovic Orban announced in January that the government would exit the deal with its Chinese partner. He invoked the European Union's Green Deal rather than security issues or cost concerns circulated previously as the main reason behind a potential end of the deal with CGN to expand Romania's only nuclear power plant, amid concerns that Europe is losing nuclear power when it needs energy.

In August last year, the US included CGN on a blacklist for allegedly trying to get nuclear technology from the US to be used for military purposes in China, even as nuclear cooperation with Cambodia expands in the region.

IRENA Climate Investment Platform accelerates renewable energy financing through de-risking, bankable projects, and public-private partnerships, advancing Paris Agreement goals via grid integration, microgrids, and decarbonization while expanding access, jobs, and sustainable economic growth.

Key Points

A global platform linking bankable renewable projects with finance, derisking and partners to scale decarbonization.

✅ Connects developers with banks, funds, and insurers

✅ Promotes de-risking via policy, PPAs, and legal frameworks

✅ Targets Paris goals with grid, microgrids, and off-grid access

The heads-of-state and energy ministers from more than 120 nations just met in Abu Dhabi and they had one thing in common: a passion to increase the use of renewable energy to reduce the threat from global warming — one that will also boost economic output and spread prosperity. Access to finance, though, is critical to this goal. 

Indeed, the central message to emerge from the conference hosted by the International Renewable Energy Agency (IRENA) this week in the United Arab Emirates is that a global energy transition is underway that has the potential to revitalize economies and to lift people out of poverty. But such a conversion requires international cooperation and a common desire to address the climate cause. 

“The renewable energy sector created jobs employing 11 million people in 2019 and provided off-grid solutions, having helped bring the number of people with no access to electricity to under 1 billion,” the current president of the UN General Assembly Tiijani Muhammad-Bande of Nigeria told the audience. 

Today In: Business
While renewables are improving energy access and reducing inequities, they also have the potential to curb CO2 emissions globally. The goal is to shrink them by 45% by 2030 and 90% by 2050, with Canada's net-zero race highlighting the role of renewable energy in achieving those targets. Getting there, though, requires progressive government policies that will help to attract financing. 

According to IRENA, investment in the clean energy sector is now at $330 billion a year. But if the 2050 goals are to be reached, those levels must nearly double to $750 billion annually. The green energy sector does not want to compete with the oil and gas sectors but rather, it is seeking to diversify fuel sources — a strategy that could help make electricity systems more resilient to climate risks. To hit the Paris agreement’s targets, it says that renewable energy deployment must increase by a factor of six.  

To that end, IRENA is forming a “climate investment platform” that will bring ideas to the table and then introduce prospective parties. It will focus on those projects that it believes are “bankable.”

It’s about helping project developers find banks, private companies and pension funds to finance their worthy projects, IRENA Director General Francesco La Camera said in response to this reporter’s question. Moreover, he said that the platform would work to ensure there is a sound legal structure and that there is legislative support to “de-risk” the investments. 

“Overcoming investment needs for energy transformation infrastructure is one of the most notable barriers to the achievement of national goals,” La Camera says. “Therefore, the provision of capital to support the adoption of renewable energy is key to low-carbon sustainable economic development and plays a central role in bringing about positive social outcomes.”

If the monies are to flow into new projects, governments have to create an environment where innovation is to be rewarded: tax incentives for renewables along with the design and implementation of transition plans. The aim is to scale up which in turn, leads to new jobs and greater economic productivity — a payback of three-to-seven times the initial investment.  

The path of least resistance, for now, is off-grid green energy solutions, or providing electricity to rural areas by installing solar panels that may connect to localized microgrids. Africa, which has a half-billion people without reliable electricity, would benefit. However, “If you want to go to scale and have bankable projects, you have to be connected to the grid,” Moira Wahba, with the UN Development Program, told this writer. “That requires large capital and private enterprise.”

Public policy must thus work to create the knowledge base and the advocacy to help de-risk the investments. Government’s role is to reassure investors that they will not be subject to arbitrary laws or the crony allocation of contracts. Risk takers know there are no guarantees. But they want to compete on a level playing. 

Analyzing Risk Profiles

How do foreign investors square the role of utilities that are considered safe and sound with their potential expansion into new fields such as investing in carbon-free electricity and in new places? The elimination of risk is not possible, says Mohamed Jameel Al Ramahi, chief executive officer of UAE-based Masdar. But the need to decarbonize is paramount. The head of the renewable energy company says that every jurisdiction has its own risk profile but that each one must be fully transparent while also properly structuring their policies and regulations. And there needs to be insurance for political risks. 

The United States and China, for example, are already “de-risked,” because they are deploying “gigawatts of renewables,” he told this writer. “When we talk about doubling the amount of needed investment, we have to take into account the risk profile of the whole world. If it is a high-risk jurisdiction, it will be difficult to bring in foreign capital.” 

The most compelling factor that will drive investment is whether the global community can comply with the Paris agreement, says Dr. Thani Ahmed Al Zeyoudi, Minister of the Ministry of Climate Change and the Environment for the United Arab Emirates. The goal is to limit increases to 2 degrees Celsius by mid-century, with the understanding that the UN’s latest climate report emphasizes that positive results are urgently needed. 

One of the most effective mechanisms is the public-private model. Governments, for example, are signing long-term power purchase agreements, giving project developers the necessary income they need to operate, and in the EU plans to double electricity use by 2050 are reinforcing these commitments. They can also provide grants and bring in international partners such as the World Bank. 

“We are seeing the impact of climate change with the various extreme events: the Australian fires, the cyclones and the droughts,” the minister told reporters. “We can no longer pass this to future generations to deal with.” 

The United Arab Emirates is not just talking about it, adds Sultan Al Jabber, chief executive of Abu Dhabi’s national oil company, Adnoc, who is also the former head of subsidiary Masdar. It is acting now, and across Europe Big Oil is turning electric as traditional players pivot too. His comments came during Abu Dhabi’s Sustainability Week at the World Future Energy Summit. The country is “walking the walk” by investing in renewable projects around the globe and it is growing its own green energy portfolio. Addressing climate change is “right” while it is also making “perfect economic sense.” 

The green energy transition has taken root in advanced economies while it is making inroads in the developing world — a movement that has the twin effect of addressing climate change and creating economic opportunities, and one that aligns with calls to transform into a sustainable electric planet for long-term prosperity. But private investment must double, which requires proactive governments to limit unnecessary risks and to craft the incentives to attract risk-takers.

BC Fossil Fuel Phase-Out outlines a just transition to a green economy, meeting climate targets by mid-century through carbon budgets, ending subsidies for fracking, capping production, and investing in renewable energy, remediation, and resilient infrastructure.

Key Points

A strategic plan to wind down oil and gas, end subsidies, and achieve climate targets with a just transition in BC.

✅ End new leases, phase out subsidies, cap fossil production

✅ Carbon budgets and timelines to meet mid-century climate targets

✅ Just transition: income supports, retraining, site remediation jobs

Politicians in British Columbia aren't focused enough on phasing out fossil fuel industries, a new report says.

The report, authored by the left-leaning Canadian Centre for Policy Alternatives, says the province must move away from fossil fuel industries by mid-century in order to meet its climate targets, with B.C. projected to fall short of 2050 targets according to recent analysis, but adds that the B.C. government is ill prepared to transition to a green economy.

"We are totally moving in the wrong direction," said economist Marc Lee, one of the authors of the report, on The Early Edition Wednesday. 

He said most of the emphasis of B.C. government policy has been on slowing reductions in emissions from transportation or emissions from buildings, even though Canada will need more electricity to hit net-zero according to the IEA, while still subsidizing fossil fuel extraction, such as fracking projects, that Lee said should be phased out.

"What we are putting on the table is politically unthinkable right now," said Lee, adding that last month's provincial budget called for a 26 per cent increased gas production over the next three years, even though electrified LNG facilities could boost demand for clean power.

B.C.'s $830M in fossil fuel subsidies undermines efforts to fight climate crisis, report says
He said B.C. needs to start thinking instead about how its going to wind down its dependence on fossil fuel industries.

'Greener' job transition needed
The report said the provincial government's continued interest in expanding production and exporting fossil fuels, even as Canada's race to net-zero intensifies across the energy sector, suggests little political will to think about a plan to move away from them.

It suggests the threat of major job losses in those industries is contributing to the political inaction, but cited several examples of ways governments can help move workers into greener jobs, as many fossil-fuel workers are ready to support the transition according to recent commentary. 

Lee said early retirement provisions or income replacement for transitioning workers are options to consider.

"We actually have seen a lot of real-world policy around transition starting to happen, including in Alberta, which brought in a whole transition package for coal workers producing coal for electricity generation, and regional cooperation like bridging the electricity gap between Alberta and B.C. could further support reliability," Lee said.

Give cities the power to move more quickly on the environment, say Metro Van politicians
Make it easier for small businesses to go green, B.C. Chamber of Commerce urges government
Lee also said well-paying jobs could be created by, for example, remediating old coal mines and gas wells and building green infrastructure and renewable electricity projects in affected areas.

The report also calls for a moratorium on new fossil fuel leases and ending fossil fuel subsidies, as well as creating carbon budgets and fossil fuel production limits.

"Change is coming," said Lee. "We need to get out ahead of it."
