Pacific Gas and Electric Company, or PG&E, recently expanded its commitment to clean energy by presenting its first 75MW of energy storage contracts to the California Public Utilities Commission for review and approval. California's Energy Storage Decision requires investor-owned utilities to procure 1,325MW of storage by 2020. PG&E's share is 580MW.

Storage is expected to play an increasingly important role for California utilities as they work to achieve the states ambitious clean energy goals. By the end of 2015, PG&E forecasts that about 30 percent of its retail electric deliveries will come from renewable sources. Energy storage will help integrate many of those resources, such as wind and solar, which are intermittent or provide peak output during times of low demand.

Energy storage has been a part of PG&E's power mix for decades, starting with the HelmÂ’s Hydroelectric Facility and continuing with pilot projects such as the 2MW Battery Storage Pilot at the Vacaville Substation and the 4MW Yerba Buena Battery Energy Storage System located on the property of Silicon Valley storage technology company HGST.

In December 2014, PG&E issued a request for offers RFO to solicit proposals for energy storage projects. In addition to third-party owned storage offers, PG&E issued a list of five distribution substations where it would like to consider energy storage projects on distribution circuits to defer distribution investments. PG&E also identified three sites where it owns and operates solar photovoltaic facilities where energy storage could be added.

Fong Wan, PG&E senior vice president for Energy Policy and Procurement, said he was pleased with the first list of projects, and the role storage will play as PG&E works to meet renewable energy and storage goals.

"PG&E supports the state's efforts to enable energy storage to play its appropriate role in the California electric grid to support the integration of utility scale and customer connected renewables, and is excited to take this first step in implementing these goals," Wan said.

Over the last 12 months PG&E staff reviewed applications from numerous vendors interested in participating in the storage market. In selecting offers for storage projects, PG&E looked for projects which met at least one of three goals – grid optimization, renewable energy integration and greenhouse gas reduction.

The seven projects selected include four Lithium Ion Battery projects, two Zinc/Air Battery storage facilities and one Flywheel project, a first for PG&E. Flywheel technology uses kinetic energy to store energy and later supply that energy to the grid.

The first projects are due to come online in May of 2017.

West Coast consumers won't benefit if Trump privatizes the electrical grid

BPA Privatization would sell the Bonneville Power Administration's transmission lines, raising FERC-regulated grid rates for ratepayers, impacting hydropower and the California-Oregon Intertie under the Trump 2018 budget proposal in the Pacific Northwest region.

 

Key Points

Selling Bonneville's transmission grid to private owners, raising rates and returns, shifting costs to ratepayers.

✅ Trump 2018 budget targets BPA transmission assets for sale.

✅ Higher capital costs, taxes, and profit would raise transmission rates.

✅ California-Oregon Intertie and hydropower flows face price impacts.

 

President Trump's 2018 budget proposal is so chock-full of noxious elements — replacing food stamps with "food boxes," drastically cutting Medicaid and Medicare, for a start — that it's unsurprising that one of its most misguided pieces has slipped under the radar.

That's the proposal to privatize the government-owned Bonneville Power Administration, which owns about three-quarters of the high-voltage electric transmission lines in a region that includes California, Washington state and Oregon, serving more than 13.5 million customers. By one authoritative estimate, any such sale would drive up the cost of transmission by 26%-44%.

The $5.2-billon price cited by the Trump administration, moreover, is nearly 20% below the actual value of the Bonneville grid — meaning that a private buyer would pocket an immediate windfall of $1.2 billion, at the expense of federal taxpayers and Bonneville customers.

Trump's plan for Portland, Ore.-based Bonneville is part of a larger proposal to sell off other government-owned electricity bodies, including the Colorado-based Western Area Power Administration and the Oklahoma-based Southwestern Power Administration. But Bonneville is by far the largest of the three, accounting for nearly 90% of the total $5.8 billion the budget anticipates collecting from the sales. The proposal is also part of the administration's

Both plans are said to be politically dead-on-arrival in Washington. But they offer a window into the thinking in the Trump White House.

"The word 'muddle' comes to mind," says Robert McCullough, a respected Portland energy consultant, referring to the justification for the privatization sale included in the Trump budget.

The White House suggests that selling the Bonneville grid would result in lower costs. But that narrative, McCullough wrote in a blistering assessment of the proposal, "displays a severe lack of understanding about the process of setting transmission rates."

McCullough's assessment is an update of a similar analysis he performed when the privatization scheme was first raised by the Trump administration last year. In that analysis issued in June, McCullough said the proposal "raises the question of why these valuable assets would be sold at a discount — and who would get the benefit of the discounted price."

The implications of a sale could be dire for Californians. Bonneville is the majority owner of the California-Oregon Intertie, an electrical transmission system that carries power, including Columbia River-generated hydropower and other clean-energy generation in British Columbia that supports the regional exchange, south to California in the summer and excess California generation to the Pacific Northwest in the winter.

But the idea has drawn fire throughout the region. When it was first broached last year, the Public Power Council, an association of utilities in the Northwest, assailed it as an apparent "transfer of value from the people of the Northwest to the U.S. Treasury," drawing parallels to Manitoba Hydro governance issues elsewhere.

The region's political leaders had especially harsh words for the idea this time around. "Oregonians raised hell last year when Trump tried to raise power bills for Pacific Northwesterners by selling off Bonneville Power, and yet his administration is back at it again," Sen. Ron Wyden (D-Ore.) said after the idea reappeared. "Our investment shouldn't be put up for sale to free up money for runaway military spending or tax cuts for billionaires." Sen. Maria Cantwell (D-Wash.) promised in a statement to work to "stop this bad idea in its tracks."

The notion of privatizing Bonneville predates the Trump administration; it was raised by Bill Clinton and again by George W. Bush, who thought the public would gain if the administration could sell its power at market rates. Both initiatives failed.

The same free-enterprise ideology underlies the Trump proposal. Privatizing the transmission lines "encourages a more efficient allocation of economic resources and mitigates unnecessary risk to taxpayers," the budget asserts. "Ownership of transmission assets is best carried out by the private sector where there are appropriate market and regulatory incentives."

But that's based on a misunderstanding of how transmission rates are set, McCullough says. Transmission is essentially a monopoly enterprise, with rates overseen by the Federal Energy Regulatory Commission based on the grid's costs, and with federal scrutiny of public utilities such as the TVA underscoring that oversight. There's very little in the way of market "incentives" involved in transmission, since no one has come forward to build a competing grid.

Those include the owners' cost of capital — which would be much higher for a private owner than a government agency, McCullough observes, as Hydro One investor uncertainty demonstrates in practice. A private owner, unlike the government-owned Bonneville, also would owe federal income taxes, which would be passed on to consumers.

Then there's the profit motive. Bonneville "currently sells and delivers its power at cost," McCullough wrote last year. "Under a private regime, an investor-owned utility would likely charge a higher rate of return, a pattern seen when UK network profits drew regulatory rebukes."

None of these considerations appears to have been factored into the White House budget proposal. "Either there's an unsophisticated person at the Office of Management and Budget thinking up these numbers himself," McCullough told me, "or there would seem to be ongoing negotiations with an unidentified third party." No such buyer has emerged in the past, however.

What's left is a blind faith in the magic of the market, compounded by ignorance about how the transmission market operates. Put it together, and there's reason to wonder if Trump is even serious about this plan.

Rooftop Solar Grids

Rooftop solar grids transform urban infrastructure with distributed generation, photovoltaic panels, smart grid integration and energy storage, cutting greenhouse gas emissions, lowering utility costs, enabling net metering and community solar for low-carbon energy systems.

 

Key Points

Rooftop solar grids are PV systems on buildings that generate power, cut emissions, and enable smart grid integration.

✅ Lowers utility bills via net metering and demand offset

✅ Reduces greenhouse gases and urban air pollution

✅ Enables resiliency with storage, smart inverters, and microgrids

 

As urban areas expand and the climate crisis intensifies, cities are seeking innovative ways to integrate renewable energy sources into their infrastructure. One such solution gaining traction is the installation of rooftop solar grids. A recent CBC News article highlights the significant impact of these solar systems on urban environments, showcasing their benefits and the challenges they present.

Harnessing Unused Space for Sustainable Energy

Rooftop solar panels are revolutionizing how cities approach energy consumption and environmental sustainability. By utilizing the often-overlooked space on rooftops, these systems provide a practical solution for generating renewable energy in densely populated areas. The CBC article emphasizes that this approach not only makes efficient use of available space but also contributes to reducing a city's reliance on non-renewable energy sources.

The ability to generate clean energy directly from buildings helps decrease greenhouse gas emissions and, as scientists work to improve solar and wind power, promotes a shift towards a more sustainable energy model. Solar panels absorb sunlight and convert it into electricity, reducing the need for fossil fuels and lowering overall carbon footprints. This transition is crucial as cities grapple with rising temperatures and air pollution.

Economic and Environmental Advantages

The economic benefits of rooftop solar grids are considerable. For homeowners and businesses, installing solar panels can lead to substantial savings on electricity bills. The initial investment in solar technology is often balanced by long-term energy savings and financial incentives, such as tax credits or rebates, and evidence that solar is cheaper than grid electricity in Chinese cities further illustrates the trend toward affordability. According to the CBC report, these financial benefits make solar energy a compelling option for many urban residents and enterprises.

Environmentally, the advantages are equally compelling. Solar energy is a renewable and clean resource, and increasing the number of rooftop solar installations can play a pivotal role in meeting local and national renewable energy targets, as illustrated when New York met its solar goals early in a recent milestone. The reduction in greenhouse gas emissions from fossil fuel energy sources directly contributes to mitigating climate change and improving air quality.

Challenges in Widespread Adoption

Despite the clear benefits, the adoption of rooftop solar grids is not without its challenges. One of the primary hurdles is the upfront cost of installation. While prices for solar panels have decreased over time, the initial financial outlay remains a barrier for some property owners, and regions like Alberta have faced solar expansion challenges that highlight these constraints. Additionally, the effectiveness of solar panels can vary based on factors such as geographic location, roof orientation, and local weather patterns.

The CBC article also highlights the importance of supportive infrastructure and policies for the success of rooftop solar grids. Cities need to invest in modernizing their energy grids to accommodate the influx of solar-generated electricity, and, in the U.S., record clean energy purchases by Southeast cities have signaled growing institutional demand. Furthermore, policies and regulations must support solar adoption, including issues related to net metering, which allows solar panel owners to sell excess energy back to the grid.

Innovative Solutions and Future Prospects

The future of rooftop solar grids looks promising, thanks to ongoing technological advancements. Innovations in photovoltaic cells and energy storage solutions are expected to enhance the efficiency and affordability of solar systems. The development of smart grid technology and advanced energy management systems, including peer-to-peer energy sharing, will also play a critical role in integrating solar power into urban infrastructures.

The CBC report also mentions the rise of community solar projects as a significant development. These projects allow multiple households or businesses to share a single solar installation, making solar energy more accessible to those who may not have suitable rooftops for solar panels. This model expands the reach of solar technology and fosters greater community engagement in renewable energy initiatives.

Conclusion

Rooftop solar grids are emerging as a key element in the transition to sustainable urban energy systems. By leveraging unused rooftop space, cities can harness clean, renewable energy, reduce greenhouse gas emissions, and, as developers learn that more energy sources make better projects, achieve long-term economic savings. While there are challenges to overcome, such as initial costs and regulatory hurdles, the benefits of rooftop solar grids make them a crucial component of the future energy landscape. As technology advances and policies evolve, rooftop solar grids will play an increasingly vital role in shaping greener, more resilient urban environments.

Electricity Prices Surge to Record as Europe Struggles to Keep Lights on

France Electricity Crisis drives record power prices as nuclear outages squeeze supply, forcing energy imports, fuel oil and coal generation, amid gas market shocks, weak wind output, and freezing weather straining the grid.

 

Key Points

A French power shortfall from nuclear outages, record prices, heavy imports, and oil-fired backup amid cold weather.

✅ EDF halted reactors; 10% capacity offline, 30% by January

✅ Imports surge; fuel oil and coal units dispatched

✅ Prices spike as gas reverses flow and wind output drops

 

Electricity prices surged to a fresh record as France scrambled to keep its lights on, sucking up supplies from the rest of Europe.

France, usually an exporter of power, is boosting electricity imports and even burning fuel oil, and has at times limited nuclear output due to high river temperatures during heatwaves. The crunch comes after Electricite de France SA said it would halt four reactors accounting for 10% of the nation’s nuclear capacity, straining power grids already facing cold weather. Six oil-fired units were turned on in France on Tuesday morning, according to a filing with Entsoe.

“It’s illustrating how severe it is when they’re actually starting to burn fuel oil and importing from all these countries,” said Fabian Ronningen, an analyst at Rystad Energy. The unexpected plant maintenance “is reflected in the market prices,” he said

Europe is facing an energy crisis, with utilities relying on coal and oil. Almost 30% of France’s nuclear capacity will be offline at the beginning of January, leaving the energy market at the mercy of the weather. To make matters worse, Germany is closing almost half of its nuclear capacity before the end of the year, as Europe loses nuclear power just when it really needs energy.

German power for delivery next year surged 10% to 278.50 euros a megawatt-hour, while the French contract for January added 9.5% to a record 700.60 euros. Prices also gained, under Europe’s marginal pricing system, as gas jumped after shipments from Russia via a key pipeline reversed direction, flowing eastward toward Poland instead.

Neighboring countries are boosting their exports to France this week to cover for lost nuclear output, with imports from Germany rising to highest level in at least four years. In the U.K., four coal power units were operating on Tuesday with as much as 1.5 gigawatts of hourly output being sent across the channel. 

The power crisis is so severe that the French government has asked EDF to restart some nuclear reactors earlier than planned amid outage risks for nuclear-powered France. Ecology Minister Barbara Pompili said last weekend that, in addition to the early reactor restarts and past river-temperature limits, the country had contracts with some companies in which they agreed to cut production during peak demand hours in exchange for payments from the government.

Higher energy prices threaten to derail Europe’s economic recovery just as the coronavirus omicron variety is spreading. Trafigura Group’s Nyrstar will pause production at its zinc smelter in France in the first week of January because of rising electricity prices. Norwegian fertilizer producer Yara International, which curbed output earlier this year, said it would continue to monitor the situation closely and curtail production where necessary.

Freezing weather this week is also sending short-term power prices surging as renewables can’t keep up, even though wind and solar overtook gas in the EU last year. German wind output plunged to a five-week low on Tuesday.

Biden administration pushes to revitalize coal communities with clean energy projects

Coal-to-Clean Energy Hubs leverage Bipartisan Infrastructure Law and Inflation Reduction Act funding to repurpose mine lands with microgrids, advanced nuclear, carbon capture, and rare earth processing, boosting energy security, jobs, and grid modernization.

 

Key Points

They are federal projects converting coal communities and mine lands into clean energy hubs, repurposing infrastructure.

✅ DOE demos on mine lands: microgrids, nuclear, carbon capture.

✅ Funding from BIL, CHIPS and IRA targets energy communities.

✅ Rare earths from coal waste bolster EV supply chains.

 

The Biden administration is channeling hundreds of millions of dollars in clean energy funding from recent legislation into its efforts to turn coal communities into clean energy hubs, the White House said.

The administration gave an update on its push across agencies to kick-start projects nationwide with funding Congress approved during Biden’s first two years in office. The effort includes $450 million from the Bipartisan Infrastructure Law that the Department of Energy will allocate to an array of new clean energy demonstration projects on former mine lands.

“These projects could focus on a range of technologies from microgrids to advanced nuclear to power plans with carbon capture,” Energy Secretary Jennifer Granholm said on a call with reporters Monday. “They’ll prove out the potential to reactivate or repurpose existing infrastructure like transmission lines and substations across an aging U.S. power grid, and these projects could spur new economic development in these communities.”

Among the projects the White House highlighted, it said $16 million from the infrastructure law will go to the University of North Dakota and West Virginia University to create design studies for the first-ever full-scale refinery facility in the U.S. that could extract and separate rare earth elements and minerals from coal mine waste streams. The materials are critical for electric vehicle-battery components that are currently heavily sourced from outside the U.S.

“Those efforts will pave the way toward building a first of its kind facility that produces essential materials for solar panels, wind turbines, EVs and more while cleaning up polluted land and water and creating good-paying jobs for local workers,” Granholm said.

Biden created an interagency working group focused on revitalizing coal-power communities through federal investments when he took office. In 2021, the group selected 25 priority areas ranging from West Virginia to Wyoming to focus on development, as high natural gas prices strengthened the case for clean electricity. There are nearly 18,000 identified mine sites across 1.5 million acres in the United States, according to the White House.

The massive effort fits into a broader Biden administration push to both fight climate change and support communities that have lost economic activity during a transition away from fossil fuel sources such as coal. While Biden’s most ambitious clean energy plans fell flat in Congress in the face of opposition from Republicans and some Democrats after the previous administration’s power plant overhaul, three major laws still unlocked funding for his administration to deploy.

Many of the initiatives are made possible through the Bipartisan Infrastructure Law, Chips and Science Act and the Inflation Reduction Act, even without a clean electricity standard on the books. The task force aims to make sure communities most affected by the changing energy landscape are taking maximum advantage of the federal benefits.

“Those new and expanded operations are coming to energy communities and creating good paying jobs,” Biden’s senior advisor for clean energy innovation and implementation John Podesta said on the call. “These laws can provide substantial federal support to energy communities like capping abandoned oil and gas wells, extracting critical minerals, building battery factories and launching demonstration projects in carbon capture or green hydrogen.”

The administration touted the potential benefits of the Inflation Reduction Act, a bill passed by Democrats to spur clean energy investments last year, even as early assessments show mixed results to date. At the time, U.S. consumers were dealing with decades-high inflation fueled in part by an energy crisis and high gas prices that drove debate — a point Republicans emphasized as the plan moved through Congress.

Deputy Treasury Secretary Wally Adeyemo said the Inflation Reduction Act aims to both “lower the deficit, as well as promote our energy security, lowering energy costs for consumers and combatting climate change.”

“As the Treasury works to implement the law, we’re focused on ensuring that all Americans benefit from the growth of the clean energy economy, particularly those who live in communities that have been dependent on the energy sector for job for a long time,” Adeyemo told reporters. “Economic growth and productivity are higher when all communities are able to reach their full potential.”

Europe's EV Slump Sounds Alarm for Climate Goals

Europe EV Sales Slowdown signals waning incentives, economic uncertainty, and supply chain constraints, threatening climate targets and net-zero emissions goals while highlighting the need for charging infrastructure, affordable batteries, and policy support across key markets.

 

Key Points

Europe's early-2024 EV registrations fell as incentives waned and supply gaps persisted, putting climate targets at risk.

✅ Fewer subsidies and tax breaks cut EV affordability

✅ Inflation and recession fears dampen car purchases

✅ Supply-chain and lithium constraints limit availability

 

A recent slowdown in Europe's electric vehicle (EV) sales raises serious concerns about the region's ability to achieve its ambitious climate targets.  After years of steady growth, new EV registrations declined in key markets like Norway, Germany, and the U.K. in early 2024. Experts are warning that this slump jeopardizes the transition away from fossil fuels and could undermine Europe's commitment to a net-zero emissions future.

 

Factors Behind the Decline

Several factors are contributing to the slowdown in EV sales:

  • Reduced Incentives: Many European countries have scaled back generous subsidies and tax breaks for EV purchases. While these incentives played a crucial role in driving early adoption, their reduction has made EVs less financially attractive for some consumers, with many U.K. buyers citing higher prices even after discounts.
  • End of ICE Ban Support: Public support for phasing out gasoline and diesel-powered cars by 2035, a key European Union policy, appears to be waning in some areas. Without robust support for this measure, consumers may be less inclined to embrace the transition to electric vehicles.
  • Economic Uncertainty: Rising inflation and fears of a recession in Europe have made consumers hesitant to invest in big-ticket purchases like new cars, regardless of fuel type. This economic uncertainty is impacting both electric and conventional vehicle sales.
  • Supply Chain Constraints: Ongoing supply chain disruptions and shortages of raw materials like lithium continue to impact the availability of affordable electric vehicles. This means potential buyers face long wait times or inflated prices even when they're ready to embrace EVs.

 

Consequences for Europe's Green Agenda

The decline in EV sales threatens Europe's plans to reduce carbon emissions and become the first climate-neutral continent by 2050, aligning with a broader push for electricity to address the climate dilemma across Europe. The transportation sector is a major contributor to greenhouse gas emissions, and the rapid electrification of vehicles is a pillar of Europe's decarbonization strategy.

The current slump highlights the need for continued policy support for the EV market, as EVs still trail gas models in many markets today, to ensure long-term growth and affordability for consumers. Without action, experts fear that Europe may find itself locked into a dependence on fossil fuels for decades to come, making its climate targets unreachable.

 

A Global Concern

Europe is a leader in electric vehicle policies and technology, during a period when global EV sales climbed markedly. The recent slowdown, however, sends a worrying signal to other regions around the world aiming to accelerate their transition to electric vehicles, including the U.S. market's Q1 dip as a cautionary example. It underscores the importance of sustained government support, investment in charging infrastructure and overcoming supply chain challenges to secure a future of widespread electric vehicle use, with many forecasts suggesting mass adoption within a decade if support continues.

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.
