China has announced new plans to confront environmental and geological problems around the Three Gorges Dam, even as a recent landslide in the region killed one construction worker, injured a second and trapped two others beneath a mound of fallen earth.

The fatal incident comes as Chinese officials are facing growing questions about the dam project, which has been dogged for years by controversy and discord. Water pollution, soil erosion and landslides are becoming recurrent issues as rising water continues to inundate more land in the reservoir behind the mammoth dam.

State-run news outlets announced a host of new environmental measures from the Three Gorges Project Committee of the State Council, the highest executive body in the Chinese government. Specifics were scarce, but the announcements described “seven projects” focused on guaranteeing safe drinking water, curbing municipal and industrial dumping and instituting an environmental monitoring system.

The proposal appears to be the same basic plan that was discussed privately in late September by select officials and experts at a closed forum about the dam. At that meeting, Wang Xiaofeng, director of the Three Gorges Project Committee, described seven environmental pilot projects that would constitute a “seven plus one” plan to “create a model for a friendly society and environment where man and nature coexist harmoniously.”

But according to a transcript of his September speech obtained by The New York Times, Mr. Wang also suggested that financing for any new environmental initiatives had not yet been approved. “My office is making an effort to push ahead with a ‘seven plus one’ special plan,” Mr. Wang said, adding that he hoped the State Council and regional government “will support it.”

In September, Mr. Wang also said that future environmental protection efforts in the Three Gorges region must focus on curbing industrial and municipal pollution into tributaries and bays of the reservoir behind the dam. Those discharges have caused algal blooms that have contaminated drinking water in certain areas, Mr. Wang said.

Other high priorities included improved efforts at water and sewage treatment; creating ecological buffer zones along the shoreline of the reservoir; and improving treatment and monitoring of geological problems such as landslides in the steep mountains above the reservoir. He said treating geological hazards was vital “to ensure the lives and property of the people in the reservoir region.”

The account from Xinhua, the official news agency, listed many of the same priorities, if with fewer details, but also cast the broader environmental situation in a more measured tone. Mr. Wang was described as saying that the dam’s environmental impact “has been less damaging than feared.”

Xinhua also stated that the current environmental issues were consistent with — or, in some cases, less severe than — predictions made in a 1991 government feasibility report about the project. Xinhua said a new official environmental assessment of the project found “positive impacts of the gigantic dam should on the whole outweigh the negatives.” That new report also said benefits such as flood prevention and power generation would not be impaired.

For years, critics have warned that the dam project would cause environmental problems like water pollution, soil erosion, geological instability and sedimentation. Chinese officials, in turn, mostly brushed aside the criticisms and usually refrained from publicly voicing any concerns about the dam project.

But after the September forum, Xinhua carried a startling account that quoted officials and experts warning of a future “catastrophe” if environmental problems were not addressed. The public airing of the controversy stunned many critics, who claimed vindication. The dam, the largest in the world, was completed last year, though the hydropower complex connected with it will not be entirely finished until 2009.

Now, Chinese officials are emphasizing that the environmental concerns are manageable, and have scheduled a news conference to discuss the situation at the Three Gorges.

Meanwhile, another landslide in the region served as a reminder of the spate of environmental problems. Xinhua reported that the slide happened in Badong County, a sloped region along the shoreline of the reservoir. A cascade of rocks and mud smashed into a construction crew working on a rail tunnel near the reservoir. The landslide crushed the four workers. No information was provided about the two men still trapped under the rubble.

In a major move to expand its renewable energy portfolio, French energy giant TotalEnergies has announced its decision to acquire German renewable energy developer VSB for US$1.65 billion. This acquisition represents a significant step in TotalEnergies' strategy to accelerate its transition from fossil fuels to greener energy sources, aligning with the global push towards sustainability and carbon reduction, as reflected in Europe's green surge across key markets.

Strengthening TotalEnergies’ Renewable Energy Portfolio

TotalEnergies has long been one of the largest players in the global energy market, historically known for its oil and gas operations. However, in recent years, the company has made a concerted effort to diversify its portfolio and shift its focus toward renewable energy. The purchase of VSB, a leading developer of wind and solar energy projects, occurs amid rising European wind investment trends and is a clear reflection of TotalEnergies' commitment to this green energy transition.

VSB, based in Dresden, Germany, specializes in the development, construction, and operation of renewable energy projects, particularly wind and solar power. The company has a significant presence in Europe, with a growing portfolio of projects in countries like Germany, where clean energy accounts for 50% of electricity today, Poland, and the Czech Republic. The acquisition will allow TotalEnergies to bolster its renewable energy capacity, particularly in the wind and solar sectors, which are key components of its long-term sustainability goals.

By acquiring VSB, TotalEnergies is not only increasing its renewable energy output but also gaining access to a highly experienced team with a proven track record in energy project development. This move is expected to expedite TotalEnergies’ renewable energy ambitions, enabling the company to build on VSB’s strong market presence and established partnerships across Europe.

VSB’s Strategic Role in the Energy Transition

VSB’s expertise in the renewable energy sector makes it a valuable addition to TotalEnergies' green energy strategy. The company has been at the forefront of the energy transition in Europe, particularly in wind energy development, as offshore wind is set to become a $1 trillion business over the coming decades. Over the years, VSB has completed numerous large-scale wind projects, including both onshore and offshore installations.

The acquisition also positions TotalEnergies to better compete in the rapidly growing European renewable energy market, including the UK, where offshore wind is powering up alongside strong demand due to increased governmental focus on achieving net-zero emissions by 2050. Germany, in particular, has set ambitious renewable energy targets as part of its Energiewende initiative, which aims to reduce the country’s carbon emissions and increase the share of renewables in its energy mix. By acquiring VSB, TotalEnergies is not only enhancing its capabilities in Germany but also gaining a foothold in other European markets where VSB has operations.

With Europe increasingly shifting toward wind and solar power as part of its decarbonization efforts, including emerging solutions like offshore green hydrogen that complement wind buildouts, VSB’s track record of developing large-scale, sustainable energy projects provides TotalEnergies with a strong competitive edge. The acquisition will further TotalEnergies' position as a leader in the renewable energy space, especially in wind and solar power generation.

Financial and Market Implications

The US$1.65 billion deal marks TotalEnergies' largest renewable energy acquisition in recent years and underscores the growing importance of green energy investments within the company’s broader business strategy. TotalEnergies plans to use this acquisition to scale up its renewable energy assets and move closer to its target of achieving net-zero emissions by 2050. The deal also positions TotalEnergies to capitalize on the expected growth of renewable energy across Europe, particularly in countries with aggressive renewable energy targets and incentives.

The transaction is also expected to boost TotalEnergies’ presence in the global renewable energy market. As the world increasingly turns to wind, solar, and other sustainable energy sources, TotalEnergies is positioning itself to be a major player in the global energy transition. The acquisition of VSB complements TotalEnergies' previous investments in renewable energy and further aligns its portfolio with international sustainability trends.

From a financial standpoint, TotalEnergies’ purchase of VSB reflects the growing trend of large energy companies investing heavily in renewable energy. With wind and solar power becoming more economically competitive with fossil fuels, this investment is seen as a prudent long-term strategy, one that is likely to yield strong returns as demand for clean energy continues to rise.

Looking Ahead: TotalEnergies' Green Transition

TotalEnergies' acquisition of VSB is part of the company’s broader strategy to diversify its energy offerings and shift away from its traditional reliance on oil and gas. The company has already made significant strides in renewable energy, with investments in solar, wind, and battery storage projects across the globe, as developments like France's largest battery storage platform underline this momentum. The VSB acquisition will only accelerate these efforts, positioning TotalEnergies as one of the foremost leaders in the clean energy revolution.

By 2030, TotalEnergies plans to allocate more than 25% of its total capital expenditure to renewable energies and electricity. The company has already set ambitious goals to reduce its carbon footprint and shift its business model to align with the global drive toward sustainability. The integration of VSB into TotalEnergies’ portfolio signals a firm commitment to these goals, ensuring the company remains at the forefront of the energy transition.

In conclusion, TotalEnergies’ purchase of VSB for US$1.65 billion marks a significant milestone in the company’s renewable energy journey. By acquiring a company with deep expertise in wind and solar power development, TotalEnergies is taking decisive steps to strengthen its position in the renewable energy market and further its ambitions of achieving net-zero emissions by 2050. This acquisition will not only enhance the company’s growth prospects but also contribute to the ongoing global shift toward clean, sustainable energy sources.

Cleaning up Canada's electricity is critical to meeting climate pledges

Canada Clean Electricity Standard targets a net-zero grid by 2035, using carbon pricing, CO2 caps, and carbon capture while expanding renewables and interprovincial trade to decarbonize power in Alberta, Saskatchewan, and Ontario.

 

Key Points

A federal plan to reach a net-zero grid by 2035 using CO2 caps, carbon pricing, carbon capture, renewables, and trade.

✅ CO2 caps and rising carbon prices through 2050

✅ Carbon capture required on gas plants in high-emitting provinces

✅ Renewables build-out and interprovincial trade to balance supply

 

A new tool has been proposed in the federal election campaign as a way of eradicating the carbon emissions from Canada’s patchwork electricity system. 

As the country’s need for power grows through the decarbonization of transportation, industry and space heating, the Liberal Party climate plan is proposing a clean energy standard to help Canada achieve a 100% net-zero-electricity system by 2035, aligning with Canada’s net-zero by 2050 target overall. 

The proposal echoes a report released August 19 by the David Suzuki Foundation and a group of environmental NGOs that also calls for a clean electricity standard, capping power-sector emissions, and tighter carbon-pricing regulations. The report, written by Simon Fraser University climate economist Mark Jaccard and data analyst Brad Griffin, asserts that these policies would effectively decarbonize Canada’s electricity system by 2035.

“Fuel switching from dirty fossil fuels to clean electricity is an essential part of any serious pathway to transition to a net-zero energy system by 2050,” writes Tom Green, climate policy advisor to the Suzuki Foundation, in a foreword to the report. The pathway to a net-zero grid is even more important as Canada switches from fossil fuels to electric vehicles, space heating and industrial processes, even as the Canadian Gas Association warns of high transition costs.

Under Jaccard and Griffin’s proposal, a clean electricity standard would be established to regulate CO2 emissions specifically from power plants across Canada. In addition, the plan includes an increase in the carbon price imposed on electricity system releases, combined with tighter regulation to ensure that 100% of the carbon price set by the federal government is charged to electricity producers. The authors propose that the current scheduled carbon price of $170 per tonne of CO2 in 2030 should rise to at least $300 per tonne by 2050.

In Alberta, Saskatchewan, Ontario, New Brunswick and Nova Scotia, the 2030 standard would mean that all fossil-fuel-powered electricity plants would require carbon capture in order to comply with the standard. The provinces would be given until 2035 to drop to zero grams CO2 per kilowatt hour, matching the 2030 standard for low-carbon provinces (Quebec, British Columbia, Manitoba, Newfoundland and Labrador and Prince Edward Island). 

Alberta and Saskatchewan targeted 
Canada has a relatively clean electricity system, as shown by nationwide progress in electricity, with about 80% of the country’s power generated from low- or zero-emission sources. So the biggest impacts of the proposal will be felt in the higher-carbon provinces of Alberta and Saskatchewan. Alberta has a plan to switch from coal-based electric power to natural gas generation by 2023. But Saskatchewan is still working on its plan. Under the Jaccard-Griffin proposal, these provinces would need to install carbon capture on their gas-fired plants by 2030 and carbon-negative technology (biomass with carbon capture, for instance) by 2035. Saskatchewan has been operating carbon capture and storage technology at its Boundary Dam power station since 2014, but large-scale rollout at power plants has not yet been achieved in Canada. 

With its heavy reliance on nuclear and hydro generation, Ontario’s electricity supply is already low carbon. Natural gas now accounts for about 7% of the province’s grid, but the clean electricity standard could pose a big challenge for the province as it ramps up natural-gas-generated power to replace electricity from its aging Pickering station, scheduled to go out of service in 2025, even as a fully renewable grid by 2030 remains a debated goal. Pickering currently supplies about 14% of Ontario’s power. 

Ontario doesn’t have large geological basins for underground CO2 storage, as Alberta and Saskatchewan do, so the report says Ontario will have to build up its solar and wind generation significantly as part of Canada’s renewable energy race, or find a solution to capture CO2 from its gas plants. The Ontario Clean Air Alliance has kicked off a campaign to encourage the Ontario government to phase out gas-fired generation by purchasing power from Quebec or installing new solar or wind power.

As the report points out, the federal government has Supreme Court–sanctioned authority to impose carbon regulations, such as a clean electricity standard, and carbon pricing on the provinces, with significant policy implications for electricity grids nationwide.

The federal government can also mandate a national approach to CO2 reduction regardless of fuel source, encouraging higher-carbon provinces to work with their lower-carbon neighbours. The Atlantic provinces would be encouraged to buy power from hydro-heavy Newfoundland, for example, while Ontario would be encouraged to buy power from Quebec, Saskatchewan from Manitoba, and Alberta from British Columbia.

The Canadian Electricity Association, the umbrella organization for Canada’s power sector, did not respond to a request for comment on the Jaccard-Griffin report or the Liberal net-zero grid proposal.

Just how much more clean power will Canada need? 
The proposal has also kicked off a debate, and an IEA report underscores rising demand, about exactly how much additional electricity Canada will need in coming decades.

In his 2015 report, Pathways to Deep Decarbonization in Canada, energy and climate analyst Chris Bataille estimated that to achieve Canada’s climate net-zero target by 2050 the country will need to double its electricity use by that year.

Jaccard and Griffin agree with this estimate, saying that Canada will need more than 1,200 terawatt hours of electricity per year in 2050, up from about 640 terawatt hours currently.

But energy and climate consultant Ralph Torrie (also director of research at Corporate Knights) disputes this analysis.

He says large-scale programs to make the economy more energy efficient could substantially reduce electricity demand. A major program to install heat pumps and replace inefficient electric heating in homes and businesses could save 50 terawatt hours of consumption on its own, according to a recent report from Torrie and colleague Brendan Haley. 

Put in context, 50 terawatt hours would require generation from 7,500 large wind turbines. Applied to electric vehicle charging, 50 terawatt hours could power 10 million electric vehicles.

While Torrie doesn’t dispute the need to bring the power system to net-zero, he also doesn’t believe the “arm-waving argument that the demand for electricity is necessarily going to double because of the electrification associated with decarbonization.”

Soaring Electricity And Coal Use Are Proving Once Again, Roger Pielke Jr's "Iron Law Of Climate"

Global Electricity Demand Surge underscores rising coal generation, lagging renewables deployment, and escalating emissions, as nations prioritize reliable power; nuclear energy and grid decarbonization emerge as pivotal solutions to the electricity transition.

 

Key Points

A rapid post-lockdown rise in power consumption, outpacing renewables growth and driving higher coal use and emissions.

✅ Coal generation rises faster than wind and solar additions

✅ Emissions increase as economies prioritize reliable baseload power

✅ Nuclear power touted for rapid grid decarbonization

 

By Robert Bryce

As the Covid lockdowns are easing, the global economy is recovering and that recovery is fueling blistering growth in electricity use. The latest data from Ember, the London-based “climate and energy think tank focused on accelerating the global electricity transition,” show that global power demand soared by about 5% in the first half of 2021. That’s faster growth than was happening back in 2018 when electricity use was increasing by about 4% per year.

The numbers from Ember also show that despite lots of talk about the urgent need to reduce greenhouse gas emissions, coal demand for power generation continues to grow and emissions from the electric sector continue to grow: up by 5% over the first half of 2019. In addition, they show that while about half of the growth in electricity demand was met by wind and solar, as low-emissions sources are set to cover almost all new demand over the next three years, overall growth in electricity use is still outstripping the growth in renewables. 

The soaring use of electricity, and increasing emissions from power generation confirm the sage wisdom of Rasheed Wallace, the volatile former power forward with the Detroit Pistons and other NBA teams, and now an assistant coach at the  University of Memphis, who coined the catchphrase: “Ball don’t lie.” If Wallace or one of his teammates was called for a foul during a basketball game that he thought was undeserved, and the opposing player missed the ensuing free throws, Wallace would often holler, “ball don’t lie,” as if the basketball itself was pronouncing judgment on the referee’s errant call. 

I often think about Wallace’s catchphrase while looking at global energy and power trends and substitute my own phrase: numbers don’t lie.

Over the past few weeks Ember, BP, and the International Energy Agency have all published reports which come to the same two conclusions: that countries all around the world — and China's electricity sector in particular — are doing whatever they need to do to get the electricity they need to grow their economies. Second, they are using lots of coal to get that juice. 

As I discuss in my recent book, A Question of Power: Electricity and the Wealth of Nations, Electricity is the world’s most important and fastest-growing form of energy. The Ember data proves that. At a growth rate of 5%, global electricity use will double in about 14 years, and as surging electricity demand is putting power systems under strain around the world, the electricity sector also accounts for the biggest single share of global carbon dioxide emissions: about 25 percent. Thus, if we are to have any hope of cutting global emissions, the electricity sector is pivotal. Further, the soaring use of electricity shows that low-income people and countries around the world are not content to stay in the dark. They want to live high-energy lives with access to all the electronic riches that we take for granted.  

 Ember’s data clearly shows that decarbonizing the global electric grid will require finding a substitute for coal. Indeed, coal use may be plummeting in the U.S. and western Europe, where U.S. electricity consumption has been declining, but over the past two years, several developing countries including Mongolia, China, Bangladesh, Vietnam, Kazakhstan, Pakistan, and India, all boosted their use of coal. This was particularly obvious in China, where, between the first half of 2019 and the first half of 2021, electricity demand jumped by about 14%. Of that increase, coal-fired generation provided roughly twice as much new electricity as wind and solar combined. In Pakistan, electricity demand jumped by about 7%, and coal provided more than three times as much new electricity as nuclear and about three times as much as hydro. (Wind and solar did not grow at all in Pakistan over that period.) 

Hate coal all you like, but its century-long persistence in power generation proves its importance. That persistence proves that climate change concerns are not as important to most consumers and policymakers as reliable electricity. In 2010, Roger Pielke Jr. dubbed this the Iron Law of Climate Policy which says “When policies on emissions reductions collide with policies focused on economic growth, economic growth will win out every time.” Pielke elaborated on that point, saying the Iron Law is a “boundary condition on policy design that is every bit as limiting as is the second law of thermodynamics, and it holds everywhere around the world, in rich and poor countries alike. It says that even if people are willing to bear some costs to reduce emissions (and experience shows that they are), they are willing to go only so far.”

Over the past five years, I’ve written a book about electricity, co-produced a feature-length documentary film about it (Juice: How Electricity Explains the World), and launched a podcast that focuses largely on energy and power. I’m convinced that Pielke’s claim is exactly right and should be extended to electricity and dubbed the Iron Law of Electricity which says, “when forced to choose between dirty electricity and no electricity, people will choose dirty electricity every time.” I saw this at work in electricity-poor places all over the world, including India, Lebanon, and Puerto Rico. 

Pielke, a professor at the University of Colorado as well as a highly regarded author on the politics of climate change and sports governance, has since elaborated on the Iron Law. During an interview in Juice, he explained it thusly: “The Iron Law says we’re not going to reduce emissions by willingly getting poor. Rich people aren't going to want to get poorer, poor people aren't going to want to get poorer.” He continued, “If there is one thing that we can count on it is that policymakers will be rewarded by populations if they make people wealthier. We're doing everything we can to try to get richer as nations, as communities, as individuals. If we want to reduce emissions, we really have only one place to go and that's technology.”

Pielke’s point reminds me of another of my favorite energy analysts, Robert Rapier, who made a salient point in his Forbes column last week. He wrote, “Despite the blistering growth rate of renewables, it’s important to keep in mind that overall global energy consumption is growing. Even though global renewable energy consumption has increased by about 21 exajoules in the past decade, overall energy consumption has increased by 51 exajoules. Increased fossil fuel consumption made up most of this growth, with every category of fossil fuels showing increased consumption over the decade.” 

The punchline here – despite my tangential reference to Rasheed Wallace — is obvious: The claims that massive reductions in global carbon dioxide emissions must happen soon are being mocked by the numbers. Countries around the world are acting in their interest, particularly when it comes to their electricity needs and that is resulting in big increases in emissions. As Ember concludes in their report, wind and solar are growing, and some analyses suggest renewables could eclipse coal by 2025, but the “electricity transition” is “not happening fast enough.”

Ember explains that in the first half of 2021, wind and solar output exceeded the output of the world’s nuclear reactors for the first time. It also noted that over the past two years, “Nuclear generation fell by 2% compared to pre-pandemic levels, as closures at older plants across the OECD, especially amid debates over European nuclear trends, exceeded the new capacity in China.” While that may cheer anti-nuclear activists at groups like Greenpeace and Friends of the Earth, the truth is obvious: the only way – repeat, the only way – the electric sector will achieve significant reductions in carbon dioxide emissions is if we can replace lots of coal-fired generation with nuclear reactors and do so in relatively short order, meaning the next decade or so. Renewables are politically popular and they are growing, but they cannot, will not, be able to match the soaring demand for the electricity that is needed to sustain modern economies and bring developing countries out of the darkness and into modernity. 

Countries like China, Vietnam, India, and others need an alternative to coal for power generation. They need new nuclear reactors that are smaller, safer, and cheaper than the existing designs. And they need it soon. I will be writing about those reactors in future columns.

Japan's power demand hit by coronavirus outbreak: industry head

Japan Power Demand Slowdown highlights reduced electricity consumption as industrial activity stalls amid the coronavirus pandemic, pressuring utilities, the grid, and manufacturing, with economic impacts monitored by Chubu Electric and the federation of electric utilities.

 

Key Points

A drop in Japan's electricity use as industrial activity slows during the coronavirus pandemic, pressuring utilities.

✅ Industrial slowdown cuts electricity consumption

✅ Utilities monitor grid stability and demand trends

✅ Pandemic-linked economic risks weigh on power sector

 

Japan's power demand has been hit by a slowdown in industrial activity due to the coronavirus outbreak, reflecting broader shifts in electricity demand worldwide, Japanese utilities federation's head said on Friday, without giving specific figures.

Electricity load profiles during lockdowns revealed changes in daily routines, as shown by lockdown electricity data across multiple regions.

Analysts have identified key shifts in U.S. electricity consumption patterns that mirror industrial slowdowns.

"We are closely watching development of the pandemic, underscoring the need for electricity during such crises, as further reduction in corporate and economic activities would lead to serious impacts," Satoru Katsuno, the chairman of Japan's federation of electric utilities and president of Chubu Electric Power Co Inc, told a news conference.

In parallel, the power industry has intensified coordination with federal partners to sustain grid reliability and protect critical workers.

Some governments, including Brazil, considered emergency loans for the power sector to stabilize utilities amid revenue pressures.

Consumer advocates warned that pandemic-related electricity shut-offs and bill burdens could exacerbate energy insecurity for vulnerable households.

Current Model For Storing Nuclear Waste Is Incomplete

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.

UAE’s nuclear power plant connects to the national grid in a major regional milestone

UAE Barakah Nuclear Plant connects Unit 1 to the grid, supplying clean electricity, nuclear baseload power, and lower carbon emissions, with IAEA oversight, FANR regulation, and South Korea collaboration, supporting energy security and economic diversification.

 

Key Points

The UAE Barakah Nuclear Plant is a four-reactor project delivering clean baseload power and reducing CO2.

✅ Unit 1 online; four reactors to supply 25% of UAE electricity

✅ Cuts 21 million tons CO2 annually; clean baseload for grid

✅ FANR-licensed; IAEA and WANO oversight ensure safety

 

Unit 1 of the UAE’s Barakah plant — the Arab world’s first nuclear energy plant in the region — has connected to the national power grid, in a historic moment enabling it to provide cleaner electricity to millions of residents and help reduce the oil-rich country’s reliance on fossil fuels. 

“This is a major milestone, we’ve been planning for this for the last 12 years now,” Mohamed Al Hammadi, CEO of Emirates Nuclear Energy Corporation (ENEC), told CNBC’s Dan Murphy in an exclusive interview ahead of the news.

Unit 1, which has reached 100% power as it steps closer to commercial operations, is the first of what will eventually be four reactors, which when fully operational are expected to provide 25% of the UAE’s electricity and reduce its carbon emissions by 21 million tons a year, according to ENEC. That’s roughly equivalent to the carbon emissions of 3.2 million cars annually.

The Gulf country of nearly 10 million is the newest member of a group of now 31 countries running nuclear power operations. It’s also the first new country to launch a nuclear power plant in three decades, the last being China’s nuclear energy program in 1990.

“The UAE has been growing from an electricity demand standpoint,”  Al Hammadi said. “That’s why we are trying to meet the demand (and) at the same time have it with less carbon emissions.”

The UAE’s electricity mix will continue to include gas and renewable energy, with “the baseload from nuclear,” including emerging next-gen nuclear designs, the CEO added, which he described as a “safe, clean and reliable source of electricity” for the country.

The project is also providing “highly compensated jobs” for the Emiratis and will introduce new industries for the country’s economy, Al Hammadi said. The company noted that it has awarded roughly 2,000 contracts worth more than $4.8 billion for local companies.

International collaboration
The UAE’s nuclear watchdog FANR, the Federal Authority for Nuclear Regulation, granted the operating license for Unit 1 in February, after an extensive inspection process to ensure the plant’s compliance with regulatory requirements. The license is expected to last 60 years. The program also involved collaboration with external bodies including the U.N.’s International Atomic Energy Agency (IAEA) and the government of South Korea, and its pre-start-up review was completed in January by the World Association of Nuclear Operators (WANO). The WANO and the IAEA have conducted over 40 inspection and review missions at Barakah.   

But the project has its critics, particularly some experts from the independent Nuclear Consulting Group non-profit, who have expressed concern about Barakah’s safety features and potential environmental risks.  

In response, ENEC said the “adherence to the highest standards of safety, quality and security is deeply embedded within the fabric of the UAE Peaceful Nuclear Energy Program.”

“The Barakah Plant meets all national and international regulatory requirements and standards for nuclear safety,” a  company statement said. It added that the reactor design had been certified by the Korea Institute of Nuclear Safety, FANR and the US-based Nuclear Regulatory Commission, “demonstrating the robustness of this design for safety and operating reliability.”

Worries of regional proliferation 
The achievement for the UAE is particularly significant given tensions in the wider region over nuclear proliferation. 

Some observers have warned of a regional arms race, though the UAE already partakes in what nuclear energy experts call the “gold standard” of civilian nuclear partnerships: The U.S.-UAE 123 Agreement for Peaceful Civilian Nuclear Energy Cooperation. It allows the UAE to receive nuclear materials, equipment and know-how from the U.S. while precluding it from developing dual-use technology by barring uranium enrichment and fuel reprocessing, the processes required for building a bomb.

By contrast, nearby Iran has suspended its compliance to the multilateral 2015 deal that regulated its nuclear power development and many fear its approach toward bomb-making capability. Meanwhile, Saudi Arabia has voiced its desire to develop a nuclear energy program without adhering to a 123 agreement.

And most recently, in the wake of a historic deal that has seen the UAE become the first Gulf country to normalize relations with Israel, Iran responded by warning the agreement would bring a “dangerous future” for the Emirati government. 

But ENEC and UAE officials emphasize the program’s commitment to safety, transparency and international cooperation, and its necessity for meeting growing electricity demand by cleaner means. 

“The nuclear industry is growing, with milestones around the world being reached, and the UAE is no exception. We are pursuing our electricity demand to meet that in a safe, secure and stable manner, and also doing it in an environmentally friendly way,” Al Hammadi said.

“Having four reactors that will provide 25% of electricity for the nation and will avoid us emitting 21 million tons of CO2 on an annual basis, as part of a broader green industrial revolution approach, is a very serious step to take — and the UAE is not talking about it, it is doing it, and we are reaping the benefits of it as we speak right now.”
