China may bid for Jordan nuclear contract

Rolls-Royce SMR UK Approval underscores nuclear innovation as regulators review a 470 MW factory-built modular reactor, aiming for grid power by 2029 to boost energy security, cut fossil fuels, and accelerate decarbonization.

Key Points

UK regulatory clearance for Rolls-Royce's 470 MW modular reactor, targeting grid power by 2029 to support clean energy.

✅ UK design approval expected by mid 2024

✅ First 470 MW unit aims for grid power by 2029

✅ Modular, factory-built; est. £1.8b per 10-acre site

A Rolls-Royce (RR.L) design for a small modular nuclear reactor (SMR) will likely receive UK regulatory approval by mid-2024, reflecting progress seen in the US NRC safety evaluation for NuScale as a regulatory benchmark, and be able to produce grid power by 2029, Paul Stein, chairman of Rolls-Royce Small Modular Reactors.

The British government asked its nuclear regulator to start the approval process in March, in line with the UK's green industrial revolution agenda, having backed Rolls-Royce’s $546 million funding round in November to develop the country’s first SMR reactor.

Policymakers hope SMRs will help cut dependence on fossil fuels and lower carbon emissions, as projects like Ontario's first SMR move ahead in Canada, showing momentum.

Speaking to Reuters in an interview conducted virtually, Stein said the regulatory “process has been kicked off, amid broader moves such as a Canadian SMR initiative to coordinate development, and will likely be complete in the middle of 2024.

“We are trying to work with the UK Government, and others to get going now placing orders, echoing expansions like Darlington SMR plans in Ontario, so we can get power on grid by 2029.”

In the meantime, Rolls-Royce will start manufacturing parts of the design that are most unlikely to change, while advancing partnerships like a MoU with Exelon to support deployment, Stein added.

Each 470 megawatt (MW) SMR unit costs 1.8 billion pounds ($2.34 billion) and would be built on a 10-acre site, the size of around 10 football fields, though projects in New Brunswick SMR debate have prompted questions about costs and timelines.

Unlike traditional reactors, SMRs are cheaper and quicker to build and can also be deployed on ships and aircraft. Their “modular” format means they can be shipped by container from the factory and installed relatively quickly on any proposed site.

Nuclear Waste Corrosion accelerates as stainless steel, glass, and ceramics interact in aqueous conditions, driving localized corrosion in repositories like Yucca Mountain, according to Nature Materials research on high-level radioactive waste storage.

Key Points

Degradation of waste forms and canisters from water-driven chemistry, causing accelerated, localized corrosion in storage.

✅ Stainless steel-glass contact triggers severe localized attack

✅ Ceramics and steel co-corrosion observed under aqueous conditions

✅ Yucca Mountain-like chemistry accelerates waste form degradation

The materials the United States and other countries plan to use to store high-level nuclear waste, even as utilities expand carbon-free electricity portfolios, will likely degrade faster than anyone previously knew because of the way those materials interact, new research shows.

The findings, published today in the journal Nature Materials (https://www.nature.com/articles/s41563-019-0579-x), show that corrosion of nuclear waste storage materials accelerates because of changes in the chemistry of the nuclear waste solution, and because of the way the materials interact with one another.

"This indicates that the current models may not be sufficient to keep this waste safely stored," said Xiaolei Guo, lead author of the study and deputy director of Ohio State's Center for Performance and Design of Nuclear Waste Forms and Containers, part of the university's College of Engineering. "And it shows that we need to develop a new model for storing nuclear waste."

Beyond waste storage, options like carbon capture technologies are being explored to reduce atmospheric CO2 alongside nuclear energy.

The team's research focused on storage materials for high-level nuclear waste -- primarily defense waste, the legacy of past nuclear arms production. The waste is highly radioactive. While some types of the waste have half-lives of about 30 years, others -- for example, plutonium -- have a half-life that can be tens of thousands of years. The half-life of a radioactive element is the time needed for half of the material to decay.

The United States currently has no disposal site for that waste; according to the U.S. General Accountability Office, it is typically stored near the nuclear power plants where it is produced. A permanent site has been proposed for Yucca Mountain in Nevada, though plans have stalled. Countries around the world have debated the best way to deal with nuclear waste; only one, Finland, has started construction on a long-term repository for high-level nuclear waste.

But the long-term plan for high-level defense waste disposal and storage around the globe is largely the same, even as the U.S. works to sustain nuclear power for decarbonization efforts. It involves mixing the nuclear waste with other materials to form glass or ceramics, and then encasing those pieces of glass or ceramics -- now radioactive -- inside metallic canisters. The canisters then would be buried deep underground in a repository to isolate it.

At the generation level, regulators are advancing EPA power plant rules on carbon capture to curb emissions while nuclear waste strategies evolve.

In this study, the researchers found that when exposed to an aqueous environment, glass and ceramics interact with stainless steel to accelerate corrosion, especially of the glass and ceramic materials holding nuclear waste.

In parallel, the electrical grid's reliance on SF6 insulating gas has raised warming concerns across Europe.

The study qualitatively measured the difference between accelerated corrosion and natural corrosion of the storage materials. Guo called it "severe."

"In the real-life scenario, the glass or ceramic waste forms would be in close contact with stainless steel canisters. Under specific conditions, the corrosion of stainless steel will go crazy," he said. "It creates a super-aggressive environment that can corrode surrounding materials."

To analyze corrosion, the research team pressed glass or ceramic "waste forms" -- the shapes into which nuclear waste is encapsulated -- against stainless steel and immersed them in solutions for up to 30 days, under conditions that simulate those under Yucca Mountain, the proposed nuclear waste repository.

Those experiments showed that when glass and stainless steel were pressed against one another, stainless steel corrosion was "severe" and "localized," according to the study. The researchers also noted cracks and enhanced corrosion on the parts of the glass that had been in contact with stainless steel.

Part of the problem lies in the Periodic Table. Stainless steel is made primarily of iron mixed with other elements, including nickel and chromium. Iron has a chemical affinity for silicon, which is a key element of glass.

The experiments also showed that when ceramics -- another potential holder for nuclear waste -- were pressed against stainless steel under conditions that mimicked those beneath Yucca Mountain, both the ceramics and stainless steel corroded in a "severe localized" way.

Other Ohio State researchers involved in this study include Gopal Viswanathan, Tianshu Li and Gerald Frankel.

This work was funded in part by the U.S. Department of Energy Office of Science.

Meanwhile, U.S. monitoring shows potent greenhouse gas declines confirming the impact of control efforts across the energy sector.

Global Electricity Demand Surge strains power markets, fuels price volatility, and boosts coal and gas generation as renewables lag, driving emissions, according to the IEA, with grids and clean energy investment crucial through 2024.

Key Points

A surge in power use that strained supply, raised prices, and drove power-sector CO2 emissions to record highs.

✅ 6% demand growth in 2021; largest absolute rise ever

✅ Coal up 9%; gas +2%; renewables +6% could not meet demand

✅ Prices doubled vs 2020; volatility hit EU, China, India

Global electricity demand surged above pre-pandemic levels in 2021, creating strains in major markets, pushing prices to unprecedented levels and driving the power sector’s emissions to a record high. Electricity is central to modern life and clean electricity is pivotal to energy transitions, but in the absence of faster structural change in the sector, rising demand over the next three years could result in additional market volatility and continued high emissions, according an IEA report released today.

Driven by the rapid economic rebound, and more extreme weather conditions than in 2020, including a colder than average winter, last year’s 6% rise in global electricity demand was the largest in percentage terms since 2010 when the world was recovering from the global financial crisis. In absolute terms, last year’s increase of over 1 500 terawatt-hours was the largest ever, according to the January 2022 edition of the IEA’s semi-annual Electricity Market Report.

The steep increase in demand outstripped the ability of sources of electricity supply to keep pace in some major markets, with shortages of natural gas and coal leading to volatile prices, demand destruction and negative effects on power generators, retailers and end users, notably in China, Europe and India. Around half of last year’s global growth in electricity demand took place in China, where demand grew by an estimated 10%, highlighting that Asia is set to use half of global electricity by 2025 according to the IEA. China and India suffered from power cuts at certain points in the second half of the year because of coal shortages.

“Sharp spikes in electricity prices in recent times have been causing hardship for many households and businesses around the world and risk becoming a driver of social and political tensions,” said IEA Executive Director Fatih Birol. “Policy makers should be taking action now to soften the impacts on the most vulnerable and to address the underlying causes. Higher investment in low-carbon energy technologies including renewables, energy efficiency and nuclear power – alongside an expansion of robust and smart electricity grids – can help us get out of today’s difficulties.”

The IEA’s price index for major wholesale electricity markets almost doubled compared with 2020 and was up 64% from the 2016-2020 average. In Europe, average wholesale electricity prices in the fourth quarter of 2021 were more than four times their 2015-2020 average, and wind and solar generated more electricity than gas in the EU during the year.  Besides Europe, there were also sharp price increases in Japan and India, while they were more moderate in the United States where gas supplies were less perturbed.

Electricity produced from renewable sources grew by 6% in 2021, but it was not enough to keep up with galloping demand. Coal-fired generation grew by 9%, with soaring electricity and coal use serving more than half of the increase in demand and reaching a new all-time peak as high natural gas prices led to gas-to-coal switching. Gas-fired generation grew by 2%, while nuclear increased by 3.5%, almost reaching its 2019 levels. In total, carbon dioxide (CO2) emissions from power generation rose by 7%, also reaching a record high, after having declined the two previous years.

“Emissions from electricity need to decline by 55% by 2030 to meet our Net Zero Emissions by 2050 Scenario, but in the absence of major policy action from governments, those emissions are set to remain around the same level for the next three years,” said Dr Birol. “Not only does this highlight how far off track we currently are from a pathway to net zero emissions by 2050, but it also underscores the massive changes needed for the electricity sector to fulfil its critical role in decarbonising the broader energy system.”

For 2022-2024, the report anticipates electricity demand growing 2.7% a year on average, although the Covid-19 pandemic and high energy prices bring some uncertainty to this outlook. Renewables are set to grow by 8% per year on average, and low-emissions sources are expected to serve more than 90% of net demand growth during this period. We expect nuclear-based generation to grow by 1% annually during the same period.

As a consequence of slowing electricity demand growth and significant renewables additions, fossil fuel-based generation is expected to stagnate in the coming years, and renewables are set to surpass coal by 2025 with coal-fired generation falling slightly as phase-outs and declining competitiveness in the United States and Europe are balanced by growth in markets like China, where electricity demand trends remain a puzzle in recent analyses, and India. Gas-fired generation is seen growing by around 1% a year.

Minnesota Carbon-Free Power by 2050 aims to shift utilities to renewable energy, wind and solar, boosting efficiency while managing grid reliability, emissions, and costs under a clean energy mandate and statewide climate policy.

Key Points

A statewide goal to deliver 100% carbon-free power by 2050, prioritizing renewables, efficiency, and grid reliability.

✅ Targets 100% carbon-free electricity statewide by 2050

✅ Prioritizes wind, solar, and efficiency before fossil fuels

✅ Faces utility cost, reliability, and legislative challenges

Gov. Tim Walz's plan for Minnesota to get 100 percent of its electricity from carbon-free sources by 2050, similar to California's 100% carbon-free mandate in scope, was criticized Tuesday at its first legislative hearing, with representatives from some of the state's smaller utilities saying they can't meet that goal.

Commerce Commissioner Steve Kelley told the House climate committee that the Democratic governor's plan is ambitious. But he said the state's generating system is "aging and at a critical juncture," with plants that produce 70 percent of the state's electricity coming up for potential retirement over the next two decades. He said it will ensure that utilities replace them with wind, solar and other innovative sources, and increased energy efficiency, before turning to fossil fuels.

"Utilities will simply need to demonstrate why clean energy would not work whenever they propose to replace or add new generating capacity," he said.

Walz's plan, announced last week, seeks to build on the success of a 2007 law that required Minnesota utilities to get at least 25 percent of their electricity from renewable sources by 2025. The state largely achieved that goal in 2017 thanks to the growth of wind and solar power, and the topic of climate change has only grown hotter, with some proposals like a fully renewable grid by 2030 pushing even faster timelines, hence the new goal for 2050.

But Joel Johnson, a lobbyist for the Minnkota Power Cooperative, testified that the governor's plan is "misguided and unrealistic" even with new technology to capture carbon dioxide emissions from power plants. Johnson added that even the big utilities that have set goals of going carbon-free by mid-century, such as Minneapolis-based Xcel Energy, acknowledge they don't know yet how they'll hit the net-zero electricity by mid-century target they have set.

Minnkota serves northwestern Minnesota and eastern North Dakota.

Tim Sullivan, president and CEO of the Wright-Hennepin Cooperative Electric Association in the Twin Cities area, said the plan is a "bad idea" for the 1.7 million state electric consumers served by cooperatives. He said Minnesota is a "minuscule contributor" to total global carbon emissions, even as the EU plans to double electricity use by 2050 to meet electrification demands.

"The bill would have a devastating impact on electric consumers," Sullivan said. "It represents, in our view, nothing short of a first-order threat to the safety and reliability of Minnesota's grid."

Isaac Orr is a policy fellow at the Minnesota-based conservative think tank, the Center for the American Experiment, which released a report critical of the plan Tuesday. Orr said all Minnesota households would face higher energy costs and it would harm energy-intensive industries such as mining, manufacturing and health care, while doing little to reduce global warming.

"This does not pass a proper cost-benefit analysis," he testified.

Environmental groups, including Conservation Minnesota and the Sierra Club, supported the proposal while acknowledging the challenges, noting that cleaning up electricity is critical to climate pledges in many jurisdictions.

"Our governor has called climate change an existential crisis," said Kevin Lee, director of the climate and energy program at the Minnesota Center for Environmental Advocacy. "This problem is the defining challenge of our time, and it can feel overwhelming."

Rep. Jean Wagenius, the committee chairwoman and Minneapolis Democrat who's held several hearings on the threats that climate change poses, said she expected to table the bill for further consideration after taking more testimony in the evening and would not hold a vote Tuesday.

While the bill has support in the Democratic-controlled House, it's not scheduled for action in the Republican-led Senate. Rep. Pat Garofalo, a Farmington Republican, quipped that it "has a worse chance of becoming law than me being named the starting quarterback for the Minnesota Vikings."

Ontario Hydro Disconnection Ban ends May 1, prompting utilities and Hydro One to push payment plans, address arrears, and link low-income assistance, as Sudbury officials urge customers to avoid spring electricity disconnections.

Key Points

A seasonal policy halting winter shutoffs in Ontario, ending May 1 as utilities emphasize payment plans and assistance.

✅ Disconnections resume after winter moratorium ends May 1.

✅ Utilities offer payment plans, arrears management, relief funds.

✅ Hydro One delays shutoffs until June 1; arrears down 60%.

The first of May has taken on new meaning this year in Ontario.

It's when the province's ban on hydro disconnections during the winter months comes to an end, even as Ontario considers extending moratoriums in some cases.

Wendy Watson, the director of communications at Greater Sudbury Utilities, says signs of the approaching deadline could be seen in their office of the past few weeks.

"We've had quite an active stream of people into our front office to catch up on their accounts and also we've had a lot of people calling us to make payment arrangements or pay their bill or deal with their arrears," she says.

Watson says there are 590 customers in Sudbury who could face possible disconnection this spring, compared with just 60 when the ban started in November.

"They will put off until tomorrow what they can avoid today," she says.

Watson says they are hoping to work with customers to figure payment plans with more choice and flexibility and avoid the need to cut power to certain homes and businesses. 

"As we like to say we're in the distribution of energy business, not the disconnection of energy business. We want you to be able to turn the lights on," she says.

Joseph Leblanc from the Social Planning Council of Sudbury says the winter hydro disconnection ban is one of several government measures that keep low income families on the brink of disaster. (CBC)

Hydro One executive vice-president of customer care Ferio Pugilese, whose utility later extended disconnection bans across its service area, tells a different story.

He says the company has worked hard to configure payment plans for customers over the last three years amid unchanged peak-rate policies and find ways for them to pay "that fit their lifestyle."

"The threat of a disconnection is not on its own something that's going to motivate someone to pay their bills," says Pugilese.

He says Hydro One is also sending out notices this spring, but won't begin cutting anyone off until June 1st.

He says that disconnections and the amount owing from outstanding bills to Hydro One are down 60 per cent in the last year. 

Ontario Energy Minister Glenn Thibeault says there is plenty of help from government programs and utility financing options like Hydro One's relief fund for those having trouble paying their power bills. (CBC)

Sudbury MPP and Energy Minister Glenn Thibeault says his hope is that people having trouble paying their power bills will talk to their hydro utility and look at the numerous programs the government offers to help low-income citizens.

"You know, I really want every customer to have a conversation with their local utility about getting back on track and we do have those programs in place," he says.

However, Joseph Leblanc, the executive director of the Social Planning Council of Sudbury, says the winter disconnection ban is just another government policy that keeps the poor on the brink of disaster.

"It's a feel good story for the government to say that, but it's a band-aid solution. We can stop the bleeding for a little while, make sure people aren't freezing to death in Ontario," he says. 

"People choose between rent, hydro, medicine, food, and there's an option for one of those to take some pressure off for a little while."

Instead, Leblanc would like to see the government fast track the province-wide implementation of the basic income program it's testing out in a few cities.

Twin States Clean Energy Link connects New England to Hydro-Quebec via a 1,200 MW transmission line, DOE-backed capacity, underground segments, existing corridors, boosting renewable energy reliability across Vermont and New Hampshire with cross-border grid flexibility.

Key Points

DOE-backed 1,200 MW line linking Hydro-Quebec to New England, adding clean capacity with underground routes.

✅ 1,200 MW cross-border capacity for the New England grid

✅ Uses existing corridors; underground in VT and northern NH

✅ DOE capacity contract lowers risk and spurs investment

A proposal to build a new transmission line to connect New England with Canadian hydropower is one step closer to reality.

The U.S. Department of Energy announced Monday that it has selected the Twin States Clean Energy Link as one of three transmission projects that will be part of its $1.3 billion cross-border transmission initiative to add capacity to the grid.

WBUR is a nonprofit news organization. Our coverage relies on your financial support. If you value articles like the one you're reading right now, give today.

Twin States is a proposal from National Grid, a utility company that serves Massachusetts, New York, and Rhode Island, and also owns transmission in England and Wales as the region advances projects like the Scotland-to-England subsea link that expand renewable flows, and the non-profit Citizens Energy Corporation.

The transmission line would connect New England with power from Hydro-Quebec, moving into the United States from Canada in Northern Vermont and crossing into New Hampshire near Dalton. It would run through parts of Grafton, Merrimack, and Hillsborough counties, routing through a substation in Dunbarton and ending at a proposed new substation in Londonderry. (Here's a map of the Twin States proposal.)

The federal funding will allow the U.S. Department of Energy to purchase capacity on the planned transmission line, which officials say reduces the risk for other investors and can help encourage others to purchase capacity.

The project has gotten support from local officials in Vermont and New Hampshire, but there are still hurdles to cross. The contract negotiation process is beginning, National Grid said, and the proposal still needs approvals from regulators before construction could begin.

First Nations communities in Canada have opposed transmission lines connecting Hydro-Quebec with New England in the past, and the company has faced scrutiny from environmental groups.

What would Twin States look like?
Transmission projects, like the failed Northern Pass proposal, have been controversial in New England, though the Great Northern Transmission Line progressed in Minnesota.

But Reihaneh Irani-Famili, vice president of capital delivery, project management and construction at National Grid, said this one is different because the developers listened to community concerns before planning the project.

“They did not want new corridors of infrastructure, so we made sure that we're using existing right of way,” she said. “They did not want the visual impact and some of the newer corridors of infrastructure, we're making sure we're undergrounding portions of the line.”

In Vermont and northern New Hampshire, the transmission lines would be buried underground along state roads. South of Littleton, they would be located within existing transmission corridors.

The developers say the lines could provide 1,200 megawatts of transmission capacity. The project would have the ability to carry electricity from hydro facilities in Quebec to New England, and would also be able to bring electricity from New England into Quebec, a step toward broader macrogrid connectivity across regions.

“Those hydro dams become giant green batteries for the region, and they hold that water until we need the electrons,” Irani-Famili said. “So if you think about our energy system not as one that sees borders, but one that sees resources, this is connecting the Quebec resources to the New England resources and helping all of us get into that cleaner energy future with a lot less build than we otherwise would have.”

Irani-Famili says the transmission line could help facilitate more clean energy resources like offshore wind coming online. In a report released last week by New Hampshire’s Department of Energy, authors said importing Canadian hydropower could be one of the most cost-effective ways to move away from fossil fuels on the electric grid.

National Grid estimates the project will help save energy customers $8.3 billion in its first 12 years. The developers are constructing a $260 million “community benefits plan” that would take some profits from the transmission line and give that money back to communities that host the transmission lines and environmental justice communities in New England.
