Pickens says natural gas “only option” for U.S.

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.

NTPC Bangladesh Power Supply Tender sees NVVN win 300 MW, long-term cross-border electricity trade to BPDB, enabled by 500 MW HVDC interconnection; rivals included Adani, PTC, and Sembcorp in the competitive bidding process.

Key Points

It is NTPC's NVVN win to supply 300 MW to Bangladesh's BPDB for 15 years via a 500 MW HVDC link.

✅ NVVN selected as L1 for short and long-term supply

✅ 300 MW to BPDB; delivery via India-Bangladesh HVDC link

✅ Competing bidders: Adani, PTC, Sembcorp

NTPC, India’s biggest electricity producer in a nation that is now the third-largest electricity producer globally, on Tuesday said it has won a tender to supply 300 megawatts (MW) of electricity to Bangladesh for 15 years.

Bangladesh Power Development Board (BPDP), in a market where Bangladesh's nuclear power is expanding with IAEA assistance, had invited tenders for supply of 500 MW power from India for short term (1 June, 2018 to 31 December, 2019) and long term (1 January, 2020 to 31 May, 2033). NTPC Vidyut Vyapar Nigam (NVVN), Adani Group, PTC and Singapore-bases Sembcorp submitted bids by the scheduled date of 11 January.

Financial bid was opened on 11 February, the company said in a statement, amid rising electricity prices domestically. “NVVN, wholly-owned subsidiary of NTPC Limited, emerged as successful bidder (L1), both in short term and long term for 300 MW power,” it said.

Without giving details of the rate at which power will be supplied, NTPC said supply of electricity is likely to commence from June 2018 after commissioning of 500 MW HVDC inter-connection project between India and Bangladesh, and as the government advances nuclear power initiatives to bolster capacity in the sector. India currently exports approximately 600 MW electricity to Bangladesh even as authorities weigh coal rationing measures to meet surging demand domestically.

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.

Black Hills Energy Corriedale Wind Farm Expansion earns regulatory approval in Wyoming, boosting capacity to over 52MW near Cheyenne with five turbines, supporting Renewable Ready customers and wind power goals under PUC and PSC oversight.

Key Points

An approved Wyoming wind project upgrade to over 52MW, adding five turbines to serve Renewable Ready customers.

✅ Adds 12.5MW via five new wind turbines near Cheyenne

✅ Cost increases to $79m; prior estimate $57m

✅ Approved by SD PUC after Wyoming PSC review

US company Black Hills Energy has received regulatory approval to increase the size of its Corriedale wind farm in Wyoming, where Wyoming wind exports to California are advancing, to over 52MW from 40MW previously.

The South Dakota Public Utilities Commission approved the additional 12.5MW capacity after the Wyoming Public Service Commission determined the boost was within commission rules, as federal initiatives like DOE wind energy awards continue to support the sector.

Black Hills Energy will install five additional turbines, raising the project cost to $79m from $57m, amid growing heartland wind investment across the region.
Corriedale will be built near Cheyenne and is expected to be placed in service in late 2020.

Similar market momentum is seen in Canada, where a Warren Buffett-linked Alberta wind farm is planned to expand capacity across the region.

Black Hills said that during the initial subscription period for its Renewable Ready program, applications of interest from eligible commercial, industrial and governmental agency customers were received in excess of the program's 40MW, underscoring the view that more energy sources can make stronger projects.

Black Hills Corporations chief executive and president Linden Evans said: “We are pleased with the opportunity to expand our Renewable Ready program, allowing us to meet our customers’ interest in renewable wind energy, which co-op members increasingly support.

“This innovative program expands our clean energy portfolio while meeting our customers’ evolving needs, particularly around cleaner and more sustainable energy, as projects like new energy generation coming online demonstrate.”

Shift from Fossil Fuels to Renewables signals an energy transition and decarbonization, as investors favor wind and solar over coal, oil, and gas due to falling ROI, policy shifts, and accelerating clean-tech innovation.

Key Points

An economic and policy-driven move redirecting capital from coal, oil, and gas to scalable wind and solar power.

✅ Driven by ROI, risk, and protests curbing fossil fuel projects

✅ Coal declines as wind and solar capacity surges globally

✅ Policy, technology, and markets speed the energy transition

This article is an excerpt from "Changing Tides: An Ecologist's Journey to Make Peace with the Anthropocene" by Alejandro Frid. Reproduced with permission from New Society Publishers. The book releases Oct. 15.

The climate and biodiversity crises reflect the stories that we have allowed to infiltrate the collective psyche of industrial civilization. It is high time to let go of these stories. Unclutter ourselves. Regain clarity. Make room for other stories that can help us reshape our ways of being in the world.

For starters, I’d love to let go of what has been our most venerated and ingrained story since the mid-1700s: that burning more fossil fuels is synonymous with prosperity. Letting go of that story shouldn’t be too hard these days. Financial investment over the past decade has been shifting very quickly away from fossil fuels and towards renewable energies, as Europe's oil majors increasingly pivot to electrification. Even Bob Dudley, group chief executive of BP — one of the largest fossil fuel corporations in the world — acknowledged the trend, writing in the "BP Statistical Review of World Energy 2017": "The relentless drive to improve energy efficiency is causing global energy consumption overall to decelerate. And, of course, the energy mix is shifting towards cleaner, lower carbon fuels, driven by environmental needs and technological advances." Dudley went on:

Coal consumption fell sharply for the second consecutive year, with its share within primary energy falling to its lowest level since 2004. Indeed, coal production and consumption in the U.K. completed an entire cycle, falling back to levels last seen almost 200 years ago around the time of the Industrial Revolution, with the U.K. power sector recording its first-ever coal-free day in April of this year. In contrast, renewable energy globally led by wind and solar power grew strongly, helped by continuing technological advances.

According to Dudley’s team, global production of oil and natural gas also slowed down in 2016. Meanwhile, that same year, the combined power provided by wind and solar energy increased by 14.6 percent: the biggest jump on record. All in all, since 2005, the installed capacity for renewable energy has grown exponentially, doubling every 5.5 years, as investment incentives expand to accelerate clean power.

The shift away from fossil fuels and towards renewables has been happening not because investors suddenly became science-literate, ethical beings, but because most investors follow the money, and Trump-era oil policies even reshaped Wall Street’s energy strategies.

It is important to celebrate that King Coal — that grand initiator of the Industrial Revolution and nastiest of fossil fuels — has just begun to lose its power over people and the atmosphere. But it is even more important to understand the underlying causes for these changes. The shift away from fossil fuels and towards renewables has been happening not because the bulk of investors suddenly became science-literate, ethical beings, but because most investors follow the money.

The easy fossil fuels — the kind you used to be able to extract with a large profit margin and relatively low risk of disaster — are essentially gone. Almost all that is left are the dregs: unconventional fossil fuels such as bitumen, or untapped offshore oil reserves in very deep water or otherwise challenging environments, like the Arctic. Sure, the dregs are massive enough to keep tempting investors. There is so much unconventional oil and shale gas left underground that, if we burned it, we would warm the world by 6 degrees or more. But unconventional fossil fuels are very expensive and energy-intensive to extract, refine and market. Additionally, new fossil fuel projects, at least in my part of the world, have become hair triggers for social unrest. For instance, Burnaby Mountain, near my home in British Columbia, where renewable electricity in B.C. is expanding, is the site of a proposed bitumen pipeline expansion where hundreds of people have been arrested since 2015 during multiple acts of civil disobedience against new fossil fuel infrastructure. By triggering legal action and delaying the project, these protests have dented corporate profits. So return on investment for fossil fuels has been dropping.

It is no coincidence that in 2017, Petronas, a huge transnational energy corporation, withdrew their massive proposal to build liquefied natural gas infrastructure on the north coast of British Columbia, as Canada's race to net-zero gathers pace across industry. Petronas backed out not because of climate change or to protect essential rearing habitat for salmon, but to backpedal from a deal that would fail to make them richer.

Shifting investment away from fossil fuels and towards renewable energy, even as fossil-fuel workers signal readiness to support the transition, does not mean we have entirely ditched that tired old story about fossil fuel prosperity.

Neoliberal shifts to favor renewable energies can be completely devoid of concern for climate change. While in office, former Texas Gov. Rick Perry questioned climate science and cheered for the oil industry, yet that did not stop him from directing his state towards an expansion of wind and solar energy, even as President Obama argued that decarbonization is irreversible and anchored in long-term economics. Perry saw money to be made by batting for both teams, and merely did what most neoliberal entrepreneurs would have done.

The right change for the wrong reasons brings no guarantees. Shifting investment away from fossil fuels and towards renewable energy does not mean we have entirely ditched that tired old story about fossil fuel prosperity. Once again, let’s look at Perry. As U.S. secretary of energy under Trump’s presidency, in 2017 he called the global shift from fossil fuels "immoral" and said the United States was "blessed" to provide fossil fuels for the world.

Turkey Point Subsequent License Renewal seeks NRC approval for FP&L to extend Units 3 and 4, three-loop pressurized water reactors near Homestead, Miami; public review, docketing, and an Atomic Safety and Licensing Board hearing.

Key Points

The NRC is reviewing FP&L's request to extend Turkey Point Units 3 and 4 operating licenses by 20 years.

✅ NRC will docket if application is complete

✅ Public review and opportunity for adjudicatory hearing

✅ Units commissioned in 1972 and 1973, near Miami

The U.S. Nuclear Regulatory Commission said Thursday that it had made available the first-ever "subsequent license renewal application," amid milestones at nuclear power projects worldwide, which came from Florida Power and Light and applies to the company's Turkey Point Nuclear Generating Station's Units 3 and 4.

The Nuclear Regulatory Commission recently made available for public review the first-ever subsequent license renewal application, which Florida Power & Light Company submitted on Jan. 1.

In the application, FP&L requests an additional 20 years for the operating licenses of Turkey Point Nuclear Generating Units 3 and 4, three-loop, pressurized water reactors located in Homestead, Florida, where the Florida PSC recently approved a municipal solid waste energy purchase, approximately 40 miles south of Miami.

The NRC approved the initial license renewal in June 2002, as new reactors at Georgia's Vogtle plant continue to take shape nationwide. Unit 3 is currently licensed to operate through July 19, 2032. Unit 4 is licensed to operate through April 10, 2033.

NRC staff is currently reviewing the application, while a new U.S. reactor has recently started up, underscoring broader industry momentum. If the staff determines the application is complete, they will docket it and publish a notice of opportunity to request an adjudicatory hearing before the NRC’s Atomic Safety and Licensing Board.

The first-ever subsequent license renewal application, submitted by Florida Power & Light Company asks for an additional 20 years for the already-renewed operating licenses of Turkey Point, even as India moves to revive its nuclear program internationally, which are currently set to expire in July of 2032 and April of 2033. The two thee-loop, pressurized water reactors, located about 40 miles south of Miami, were commissioned in July 1972 and April 1973.

If the application is determined to be complete, the staff will docket it and publish a notice of opportunity to request an adjudicatory hearing before the NRC’s Atomic Safety and Licensing Board, the agency said.

The application is available for public review on the NRC website. Copies of the application will be available at the Homestead Branch Library in Homestead, the Naraja Branch Library in Homestead and the South Dade Regional Library in Miami.
