Proposed power plant gets no static at meeting

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.

Vehicle-to-Grid Revenue helps EV owners earn income via V2G, demand response, and ancillary services by exporting stored energy, supporting grid balancing, smart charging, and renewable integration with two-way charging infrastructure.

Key Points

Income EV owners earn by selling battery power to the grid for balancing, response, and flexibility services.

✅ Earn up to about $1,530 annually in Denmark trials

✅ Requires V2G-compatible EVs and two-way smart chargers

✅ Provides ancillary services and supports renewable integration

Electric car owners are earning as much as $1,530 a year just by parking their vehicle and feeding excess power back into the grid, effectively selling electricity back to the grid under V2G schemes.

Trials in Denmark carried out by Nissan and Italy’s biggest utility Enel Spa showed how batteries inside electric cars could, using vehicle-to-grid technology, help balance supply and demand at times and provide a new revenue stream for those who own the vehicles.

Technology linking vehicles to the grid marks another challenge for utilities already struggling to integrate wind and solar power into their distribution system. As the use of plug-in cars spreads, grid managers will have to pay closer attention and, with proper management, to when motorists draw from the system and when they can smooth variable flows.

For example, California's grid stability efforts include leveraging EVs as programs expand.

“If you blindingly deploy in the market a massive number of electric cars without any visibility or control over the way they impact the electricity grid, you might create new problems,” said Francisco Carranza, director of energy services at Nissan Europe in an interview with Bloomberg New Energy Finance.

While the Tokyo-based automaker has trials with more than 100 cars across Europe, only those in Denmark are able to earn money by feeding power back into the grid. There, fleet operators collected about 1,300 euros ($1,530) a year using the two-way charge points, said Carranza.

Restrictions on accessing the market in the U.K. means the company needs to reach about 150 cars before they can get paid for power sent back to the grid. That could be achieved by the end of this year, he said.

“It’s feasible,” he said. “It’s just a matter of finding the appropriate business model to deploy the business wide-scale.’’

Electric car demand globally is expected to soar, challenging state power grids and putting further pressure on grid operators to find new ways of balancing demand. Power consumption from vehicles will grow to 1,800 terawatt-hours in 2040 from just 6 terawatt-hours now, according to Bloomberg New Energy Finance.

UK Electricity Interconnectors secure capacity market subsidies, supporting winter reliability with seabed cables to France and Belgium via the Channel Tunnel, lowering consumer costs, squeezing coal, and challenging new gas plants through cross-border energy trading.

Key Points

High-voltage cables linking Britain to Europe, securing backup capacity, cutting costs and boosting winter reliability.

✅ Won capacity market contracts at record-low prices

✅ Cables to France and Belgium via Channel Tunnel, seabed routes

✅ Squeezes coal, challenges new gas; renewables may join market

New electricity cables across the Channel to France and Belgium will be a key part of keeping Britain’s lights on during winter amid record electricity prices across Europe in the early 2020s, after their owners won backup power subsidies in a government auction this week.

For the first time, interconnector operators successfully bid for a slice of hundreds of millions’ worth of contracts in the capacity market. That will help cut costs for consumers, given how electricity is priced in Europe today, and squeeze out old coal power plants.

Three new interconnectors are currently being built to Europe, almost doubling existing capacity, with one along the Channel Tunnel and two on the seabed: one between Kent and Zeebrugge and one from Hampshire to Normandy. 

The interconnectors were success stories in this week’s capacity auction, which saw power firms bid to provide backup electricity in the winter of 2021/22. Prices for the four-year contracts hit a record low of £8.40 per kilowatt per year, which analysts described as a shock and well below expectations.

One industry source said the figure was “miles away” from what is needed to encourage companies to build big new gas power stations, which some argue are necessary to fill the gap when the UK’s ageing nuclear reactors close as Europe loses nuclear power across the region over the next decade.

While bad news for those firms, the low price is good for consumers. The subsidies will add about £525m to energy bills, or £5.68 for the average household, compared with £11 for the year before, according to analysts Cornwall Insight.

Existing gas power stations scooped up most of the contracts, but new gas ones lost out, as did several coal plants. Battery storage plants, a standout success in the last auction, fared comparatively poorly after changes to the rules.

Experts at Bernstein bank said the the misses by coal meant that around half the UK’s remaining coal power capacity could close from October 2019, when existing capacity market contracts run out. Chaitanya Kumar, policy adviser at thinktank Green Alliance, said: “Coal’s exit from the UK’s energy system just moved a step closer as coal contracts fell by half compared with last year.”

Tom Edwards, an analyst at Cornwall Insight, said that more interconnectors were likely to bid into future rounds of the capacity market, such as the cable being laid between Norway and the UK. Relying on foreign power supplies was fine, he said, provided Brexit did not make energy trading more difficult and the interconnectors delivered at times of need, where events like Irish grid price spikes illustrate the stress points.

However, one industry source, who wants to see new gas plants built in the UK, said the results showed that the system was not working, amid UK peak power prices that have climbed in recent trading. “That self-sufficiency doesn’t seem to be a priority at a time when we’re breaking away from Europe is a bit weird,” they said.

But the prospects for new gas plants in future rounds of the capacity market look bleak. They will very likely face a new source of competition next year, if energy regulator Ofgem approves a proposal to allow renewables to compete too.

Australia Clean Energy Target drives renewables in the National Electricity Market, with RepuTex modelling and the Finkel Review showing lower wholesale prices and emissions as gas generators set prices less often under ambitious targets.

Key Points

Policy boosting low emissions generation to cut electricity emissions and lower wholesale prices across Australia.

✅ Ambitious targets lower wholesale prices through added generation

✅ RepuTex modelling shows renewables displace costly gas peakers

✅ Finkel Review suggests CET cuts emissions and boosts reliability

The more ambitious a clean energy target is, the lower Australian wholesale electricity prices will be, according to new modelling by energy analysis firm RepuTex.

The Finkel review, released last month recommended the government introduce a clean energy target (CET), which it found would cut emissions from the national electricity market and put downward pressure on both wholesale and retail prices, aligning with calls to favor consumers over generators in market design.

The Finkel review only modelled a CET that would cut emissions from the electricity sector by 28% below 2005 levels by 2030. But all available analysis has demonstrated that such a cut would not be enough to meet Australia’s overall emissions reductions made as part of the Paris agreement, which themselves were too weak to help meet the central aim of that agreement – to keep global warming to “well below 2C”.

RepuTex modelled the effect of a CET that cut emissions from the electricity sector by 28% – like that modelled in the Finkel Review – as well as one it said was consistent with 2C of global warming, which would cut emissions from electricity by 45% below 2005 levels by 2030.

It found both scenarios caused wholesale prices to drop significantly compared to doing nothing, despite IEA warnings on falling energy investment that could lead to shortages, with the more ambitious scenario resulting in lower wholesale prices between 2025 and 2030.

In the “business as usual scenario”, RepuTex found wholesale prices would hover roughly around the current price of $100 per MWh.

Under a CET that reduced electricity emissions by 28%, prices would drop to under $40 around 2023, and then rise to nearly $60 by 2030.

The more ambitious CET had a broadly similar effect on wholesale prices. But RepuTex found it would drive prices down a little slower, but then keep them down for longer, stabilising at about $40 to $50 for most of the 2020s.

It found a CET would drive prices down by incentivising more generation into the market. The more ambitious CET would further suppress prices by introducing more renewable energy, resulting in expensive gas generators less often being able to set the price of electricity in the wholesale market, a dynamic seen with UK natural gas price pressures recently.

The downward pressure of a CET on wholesale prices was more dramatic in the RepuTex report than in Finkel’s own modelling. But that was largely because, as Alan Finkel himself acknowledged, the estimates of the costs of renewable energy in the Finkel review modelling were conservative.

Speaking at the National Press Club, Finkel said: “We were conservative in our estimates of wind and large-scale solar generator prices. Indeed, in recent months the prices for wind generation have already come in lower than what we modelled.”

The RepuTex modelling also found the economics of the national electricity market no longer supported traditional baseload generation – such as coal power plants that were unable to respond flexibly to demand, with debates over power market overhauls in Alberta underscoring similar tensions – and so they would not be built without the government distorting the market.

“With a premium placed on flexible generation that can ramp up or down, baseload only generation – irrespective of how clean or dirty it is – is likely to be too inflexible to compete in Australia’s future electricity system,” the report said.

“In this context, renewable energy remains attractive to the market given it is able to deliver energy reliability, with no emissions, at low cost prices, with clean grid and battery trends in Canada informing the shift for policymakers. This affirms that renewables are a lay down misere to out-compete traditionally fossil-fuel sources in Australia for the foreseeable future.”

EU Nuclear Reactor Life Extension focuses on energy security, carbon-free electricity, and safety as ageing reactors face gas shortages, high power prices, and regulatory approvals across the UK and EU amid winter supply risks.

Key Points

EU Nuclear Reactor Life Extension is the policy to keep ageing reactors safely generating affordable, low-carbon power.

✅ Extends reactor operation via inspections and component upgrades

✅ Addresses gas shortages, price volatility, and winter supply risks

✅ Requires national regulator approval and cost-benefit analysis

Shaken by the loss of Russian natural gas since the invasion of Ukraine, European countries are questioning whether they can extend the lives of their ageing nuclear reactors to maintain the supply of affordable, carbon-free electricity needed for net-zero across the bloc — but national regulators, companies and governments disagree on how long the atomic plants can be safely kept running.

Europe avoided large-scale blackouts last winter despite losing its largest supplier of natural gas, and as Germany temporarily extended nuclear operations to bolster stability, but industry is still grappling with high electricity prices and concerns about supply.

Given warnings from the International Energy Agency that the coming winters will be particularly at risk from a global gas shortage, governments have turned their attention to another major energy source — even as some officials argue nuclear would do little to solve the gas issue in the near term — that would exacerbate the problem if it too is disrupted: Europe’s ageing fleet of nuclear power plants.

Nuclear accounts for nearly 10% of energy consumed in the European Union, with transport, industry, heating and cooling traditionally relying on coal, oil and natural gas.

Historically nuclear has provided about a quarter of EU electricity and 15% of British power, even as Germany shut down its last three nuclear plants recently, underscoring diverging national paths.

Taken together, the UK and EU have 109 nuclear reactors running, even as Europe is losing nuclear power in several markets, most of which were built in the 1970s and 1980s and were commissioned to last about 30 years.

That means 95 of those reactors — nearly 90% of the fleet — have passed or are nearing the end of their original lifespan, igniting debates over how long they can safely continue to be granted operating extensions, with some arguing it remains a needed nuclear option for climate goals despite age-related concerns.

Regulations differ across borders, with some countries such as Germany turning its back on nuclear despite an ongoing energy crisis, but life extension discussions are usually a once-a-decade affair involving physical inspections, cost/benefit estimates for replacing major worn-out parts, legislative amendments, and approval from the national nuclear safety authority.

Port of Vancouver Wind Turbine Blades arrive from China for a Saskatchewan wind farm, showcasing record oversized cargo logistics, tandem crane handling, renewable energy capacity, and North America's longest blades from Goldwind.

Key Points

Record-length blades for a Canadian wind farm, boosting renewable energy and requiring heavy-lift logistics at the port.

✅ 27 blades unloaded via tandem cranes with cage supports

✅ 50 turbines headed to Assiniboia over 21 weeks

✅ Largest 250 ft blades to arrive; reduced CO2 vs coal

A set of 220-foot-long wind turbine blades arrived at the Port of Vancouver from China over the weekend as part a shipment bound for a wind farm in Canada, alongside BC generating stations coming online in the region.

They’re the largest blades ever handled by the port, and this summer, even larger blades will arrive as companies expand production such as GE’s blade factory in France to meet demand — the largest North America has ever seen.

Alex Strogen described the scene as crews used two tandem cranes to unload 27 giant white blades from the MV Star Kilimanjaro, which picked up the wind turbine assemblies in China. They were manufactured by Goldwind Co.

“When you see these things come off and put onto these trailers, it’s exceptional in the sheer length of them,” Strogen said. “It looks as long as an airplane.”

In fact, each blade is about as long as the wingspan of a Boeing 747.

Groups of longshoremen attached the cranes to each blade and hoisted it into the air and onto a waiting truck. Metal cage-like devices on both ends kept the blades from touching the ground. Once loaded onto the trucks, the blades and shaft parts head to a terminal to be unloaded by another group of workers.

Another fleet of trucks will drive the wind turbines, towers and blades to Assiniboia, Saskatchewan, Canada, over the course of 21 weeks. Potentia Renewables of Toronto is erecting the turbines on 34,000 acres of leased agriculture land, amid wind farm expansion in PEI elsewhere in the country, according to a news release from the Port of Vancouver.

Potentia’s project, called the Golden South Wind Project, will generate approximately 900,000 megawatt-hours of electricity. It also has greatly reduced CO2 emissions compared with a coal-fired plant, and complements tidal power in Nova Scotia in Canada’s clean energy mix, according to the news release.

The project is expected to be operating in 2021, similar to major UK offshore wind additions coming online.

The Port of Vancouver will receive 50 full turbines of two models for the project, as Manitoba invests in new turbines across Canada. In August, the larger of the models, with blades measuring 250 feet, will arrive. They’ll be the longest blades ever imported into any port in North America.

“It’s an exciting year for the port,” said Ryan Hart, chief external affairs officer.

The Port of Vancouver is following all the recommended safety precautions during the COVID-19 pandemic, including social distancing and face masks, Strogen said, with support from initiatives like Bruce Power’s PPE donation across Canada.
As for crews onboard the ships, the U.S. Coast Guard is the agency in charge, and it is monitoring the last port-of-call for all vessels seeking to enter the Columbia River, Hart wrote in an email.

Vessel masters on each ship are responsible for monitoring the health of the crew and are required to report sick or ill crew members to the USCG prior to arrival or face fines and potential arrest.
