EPRI to offer new renewable integration research programs

Electric Field-Induced Glass Softening reveals a Joule heating anomaly in silicate glass, where anode-side nanoscale alkali depletion drives ionic conduction, localized thermal runaway, melting, and evaporation, challenging homogeneity assumptions and refining materials processing models.

Key Points

An effect where electric fields lower glass softening temperature via nanoscale ionic migration and structural change.

✅ Anode-side alkali depletion creates extreme, localized heating

✅ Thermal runaway melts glass near the anode despite uniform bulk

✅ Findings refine Joule heating models and enable new glass processing

A team of scientists working with electrical currents and silicate glass have been left gobsmacked after the glass appeared to defy a basic physical law, in a field that also explores electricity-from-air devices for novel energy harvesting.

If you pass an electrical current through a material, the way that current generates heat can be described by Joule's first law. It's been observed time and time again, with the temperature always evenly distributed when the material is homogeneous (or uniform).

But not in this recent experiment. A section - and only a section - of silicate glass became so hot that it melted, and even evaporated. Moreover, it did so at a much lower temperature than the boiling point of the material.

The boiling point of pure silicate glass is 2,230 degrees Celsius (4,046 degrees Fahrenheit). The hottest temperature the researchers recorded in a homogeneous piece of silicate glass during the experiment was 1,868.7 degrees Celsius.

Say whaaaat.

"The calculations did not add up to explain what we were seeing as simply standard Joule heating," said engineer and materials scientist Himanshu Jain of Lehigh University.

"Even under very moderate conditions, we observed fumes of glass that would require thousands of degrees higher temperature than Joule's law could predict!"

Jain and his colleagues from materials science company Corning Incorporated were investigating a phenomenon they had described in a previous paper. In 2015, they reported that an electric field could reduce the temperature at which glass softens, by as much as a few hundred degrees, a line of inquiry that parallels work on low-cost heat-to-electricity materials in energy research. They called this "electric field-induced softening."

It was certainly a peculiar phenomenon, so they set up another experiment. They put pieces of glass in a furnace, and applied 100 to 200 volts in the form of both alternating and direct currents.

Next, a thin wisp of vapour emanated from the spot where the anode conveying the current contacted the glass.

"In our experiments, the glass became more than a thousand degrees Celsius hotter near the positive side than in the rest of the glass, which was very surprising considering that the glass was totally homogeneous to begin with," Jain said.

This seems to fly in the face of Joule's first law, so the team investigated more closely - and found that the glass wasn't remaining as homogeneous as it started out. The electric field changed the chemistry and the structure of the glass on nanoscale, in just a small section close to the anode.

This region heats faster than the rest of the glass, to the point of becoming a thermal runaway - where an increase in temperature further increases temperature in a blistering feedback loop.

As it turned out, that spot of structural change and dramatic heat resulted in a small area of glass reaching melting point while the rest of the material remained solid.

"Unlike electronically conducting metals and semiconductors, with time the heating of ionically conducting glass becomes extremely inhomogeneous with the formation of a nanoscale alkali-depletion region, such that the glass melts near the anode, even evaporates, while remaining solid elsewhere," the researchers wrote in their paper.

In other words, the material wasn't homogeneous any more, which means the glass heating experiment doesn't exactly change how we apply Joule's first law.

But it's an exciting result, since until now we didn't know a material could actually lose its homogeneity with the application of an electrical current, with possible implications for thin-film heat harvesters in electronics. (The thing is, no one had tried electrically heating glass to these extreme temperatures before.)

So the physical laws of the Universe are still okay, as a piece of glass hasn't broken them. But Joule's first law may need a bit of tweaking to take this effect into account, a reminder that unconventional energy concepts like nighttime solar cells also challenge our intuitions.

And, of course, it's another piece of understanding that could help us in other ways too, including advances in thermoelectric materials that turn waste heat into electricity.

"Besides demonstrating the need to qualify Joule's law," Jain said, "the results are critical to developing new technology for the fabrication and manufacturing of glass and ceramic materials."

The research has been published in Scientific Reports.

Global Energy Electrification drives IEA targets as smart grids, storage, EVs, and demand-side management scale. Paris Agreement-aligned policies and innovation accelerate decarbonization, enabling flexible, low-carbon power systems and net-zero pathways by 2060.

Key Points

A shift to electricity across sectors via smart grids, storage, EVs, and policy to cut CO2 and improve energy security.

✅ Smart grids, storage, DSM enable flexible, resilient power.

✅ Aligns with IEA pathways and Paris Agreement goals.

✅ Drives EV adoption, building efficiency, and net-zero by 2060.

The global energy system is changing, with European electricity market trends highlighting rapid shifts. More people are connecting to the grid as living standards improve around the world. Demand for consumer appliances and electronic devices is rising. New and innovative transportation technologies, such as electric vehicles and autonomous cars are also boosting power demand.

The International Energy Agency's latest report on energy technologies outlines how these and other trends as well as technological advances play out in the next four decades to reshape the global energy sector.

Energy Technology Perspectives 2017 (ETP) highlights that decisive policy actions and market signals will be needed to drive technological development and benefit from higher electrification around the world. Investments in stronger and smarter infrastructure, including transmission capacity, storage capacity and demand side management technologies such as demand response programs are necessary to build efficient, low-carbon, integrated, flexible and robust energy system. 

Still, current government policies are not sufficient to achieve long-term global climate goals, according to the IEA analysis, and warnings about falling global energy investment suggest potential supply risks as well. Only 3 out of 26 assessed technologies remain “on track” to meet climate objectives, according to the ETP’s Tracking Clean Energy Progress report. Where policies have provided clean signals, progress has been substantial. However, many technology areas suffer from inadequate policy support. 

"As costs decline, we will need a sustained focus on all energy technologies to reach long-term climate targets," said IEA Executive Director Dr Fatih Birol. "Some are progressing, but too few are on track, and this puts pressure on others. It is important to remember that speeding the rate of technological progress can help strengthen economies, boost energy security while also improving energy sustainability."

ETP 2017’s base case scenario, known as the Reference Technology Scenario (RTS), takes into account existing energy and climate commitments, including those made under the Paris Agreement. Another scenario, called 2DS, shows a pathway to limit the rise of global temperature to 2ºC, and finds the global power sector could reach net-zero CO2 emissions by 2060.

A second decarbonisation scenario explores how much available technologies and those in the innovation pipeline could be pushed to put the energy sector on a trajectory beyond 2DS. It shows how the energy sector could become carbon neutral by 2060 if known technology innovations were pushed to the limit. But to do so would require an unprecedented level of policy action and effort from all stakeholders.

Looking at specific sectors, ETP 2017 finds that buildings could play a major role in supporting the energy system transformation. High-efficiency lighting, cooling and appliances could save nearly three-quarters of today’s global electricity demand between now and 2030 if deployed quickly. Doing so would allow a greater electrification of the energy system that would not add burdens on the system. In the transportation system, electrification also emerges as a major low-carbon pathway, with clean grids and batteries becoming key areas to watch in deployment.

The report finds that regardless of the pathway chosen, policies to support energy technology innovation at all stages, from research to full deployment, alongside evolving utility trends that operators need to watch, will be critical to reap energy security, environmental and economic benefits of energy system transformations. It also suggests that the most important challenge for energy policy makers will be to move away from a siloed perspective towards one that enables systems integration.

BWI Power Outage caused flight delays, cancellations, and diversions after a downed power line near Baltimore/Washington International. BGE crews responded as terminal operations, security screening, and boarding slowed, exposing infrastructure gaps and backup power needs.

Key Points

A downed power line disrupted BWI, causing delays, diversions, and slowed operations after power was restored by noon.

✅ Downed power line near airport spurred terminal-wide disruptions

✅ 150+ delays, dozens of cancellations; diversions to nearby airports

✅ BGE response, backup power gaps highlight infrastructure resilience

On the morning of March 3, 2025, a major power outage at Baltimore/Washington International Thurgood Marshall Airport (BWI) caused significant disruptions to air travel, much like the London morning outage that upended routines, affecting both departing and incoming flights. The outage, which began around 7:40 a.m., was caused by a downed power line near the airport, according to officials from Baltimore Gas and Electric Company. Although power was restored by noon, the effects were felt for several hours, resulting in flight delays, diversions, and a temporary disruption to airport operations.

Flight Disruptions and Delays

The outage severely impacted operations at BWI, with more than 150 flights delayed and dozens more canceled. The airport, which serves as a major hub for both domestic and international travel, was thrown into chaos, similar to the Atlanta airport blackout that snarled operations, as power outages affected various critical areas, including parts of the main terminal and an adjacent parking garage. The downed power line created a ripple effect throughout the airport’s operations, delaying not only the check-in and security screening processes but also the boarding of flights. In addition to the delays, some inbound flights had to be diverted to nearby airports, further complicating an already strained travel schedule.

With the disruption affecting vital functions of the airport, passengers were advised to stay in close contact with their airlines for updated flight statuses and to prepare for longer-than-usual wait times.

Impact on Passengers

As power began to return to different parts of the terminal, airport officials reported that airlines were improvising solutions to continue the deplaning process, such as using air stairs to help passengers exit planes that were grounded due to the power outage, a reminder of how transit networks can stall during grid failures, as seen with the London Underground outage that frustrated commuters. This created further delays for passengers attempting to leave the airport or transfer to connecting flights.

Many passengers, who were left stranded in the terminal, faced long lines at ticket counters, security checkpoints, and concessions as the airport worked to recover from the loss of power, a situation mirrored during the North Seattle outage that affected thousands. The situation was compounded by the fact that while power was restored by midday, the airport still struggled to return to full operational capacity, creating significant inconvenience for travelers.

Power Restoration and Continued Delays

By around noon, officials confirmed that power had been fully restored across the main terminal. However, the full return to normalcy was far from immediate. Airport staff continued to work on clearing backlogs and assisting passengers, but the effects of the outage lingered throughout the day. Passengers were warned to expect continued delays at ticket counters, security lines, and concessions as the airport caught up with the disruption caused by the morning’s power outage.

For many travelers, the experience was a reminder of how dependent airports and airlines are on uninterrupted power to function smoothly. The disruption to BWI serves as a case study in the potential vulnerabilities of critical infrastructure that is not immune to the effects of power failure, including weather-driven events like the windstorm outages that can sever lines. Moreover, it highlights the difficulties of recovering from such incidents while managing the expectations of a large number of stranded passengers.

Investigations into the Cause of the Outage

As of the latest reports, Baltimore Gas and Electric Company (BGE) crews were still investigating the cause of the power line failure, including weather-related factors seen when strong winds in the Miami Valley knocked out power. While no definitive cause had been provided by early afternoon, BGE spokesperson Stephanie Weaver confirmed that the company was working diligently to restore service. She noted that the downed line had caused widespread disruptions to electrical service in the area, which were exacerbated by the airport’s significant reliance on a stable power supply.

BWI officials remained in close contact with BGE to monitor the situation and ensure that necessary precautions were taken to prevent further disruptions. With power largely restored by midday, focus turned to the logistical challenges of clearing the resulting delays and assisting passengers in resuming their travel plans.

Response from the Airport and Airlines

In response to the power outage, BWI officials encouraged travelers to remain patient, a familiar message during prolonged events like Houston's extended outage in recent months, and continue checking their flight statuses. Although flight tracking websites and social media posts provided timely updates, passengers were urged to expect long delays throughout the day as the airport struggled to return to full capacity.

Airlines, for their part, worked swiftly to accommodate affected passengers, although the situation created a ripple effect across the airport's operations. With delayed flights and diverted planes, air traffic control and ground crews had to adjust flight schedules accordingly, resulting in even more congestion at the airport. Airlines coordinated with the airport to prioritize urgent cases, and some flights were re-routed to other nearby airports to mitigate the strain on the terminal.

Long-Term Effects on Airport Infrastructure

This incident underscores the importance of maintaining resilient infrastructure at key transportation hubs like BWI. Airports are vital nodes in the air travel network, and any disruption, whether from power failure or other factors, can have far-reaching consequences on both domestic and international travel. Experts suggest that BWI and other major airports should consider implementing backup power systems and other safeguards to ensure that they can continue to function smoothly during unforeseen disruptions.

While BWI officials were able to resolve the situation relatively quickly, the power outage left many passengers frustrated and inconvenienced. This incident serves as a reminder of the need for airports and utilities to have robust contingency plans in place to handle emergencies and prevent delays from spiraling into more significant disruptions.

The power outage at Baltimore/Washington International Airport highlights the vulnerability of critical infrastructure to power failures and the cascading effects such disruptions can have on travel. Although power was restored by noon, the delays, diversions, and logistical challenges faced by passengers underscore the need for greater resilience in airport operations. With travel back on track, BWI and other airports will likely revisit their contingency plans to ensure that they are better prepared for future incidents that could affect air travel.

Manus Island Naval Base strengthens US-Australia-PNG cooperation at Lombrum, near the South China Sea, bolstering sovereignty, maritime rights, and Pacific security amid APEC talks, infrastructure investment, and Belt and Road competition.

Key Points

A US-Australia-PNG facility at Lombrum to bolster Pacific security and protect maritime rights across the region.

✅ Shared by US, Australia, and PNG at Lombrum on Manus Island

✅ Near South China Sea, reinforcing maritime security and access

✅ Counters opaque lending, aligns with free trade and infrastructure

Scott Morrison has caught himself bang in the middle of escalating tensions between the United States and China.

The US and Australia will share a naval base in the north end of Papua New Guinea on Manus Island, creating another key staging point close to the contested South China Sea.

“The United States will partner with Papua New Guinea and Australia on their joint initiative at Lombrum Naval Base,” US Vice President Mike Pence said.

“We will work with these two nations to protect sovereignty and maritime rights in the Pacific Islands. ”

At an Asia Pacific Economic Cooperation meeting in Port Moresby on Saturday, Mr Morrison urged nations to embrace free trade and avoid “unsustainable debt”, as the Philippines' clean energy commitment also featured in discussions.

He confirmed the US and Australia will share an expanded naval base on Manus Island, as the US ramped up rhetoric against China.

Mr Pence quoted President Donald Trump in his speech following Chinese President Xi Jinping, even as a Biden energy agenda is seen by some as better for Canada.

“We have great respect for President Xi and respect for China. But in the president’s words, China’s taken advantage of the United States for many, many years,” he said.

“And those days are over.”

His speech was met with stony silence from the Chinese delegation, after President Xi had reassured leaders his Belt and Road Initiative was not a debt trap.

China has also been at loggerheads with the United States over its territorial ambitions in the Pacific, encapsulated by Xi’s Belt and Road Initiative.

Unveiled in 2013, the Belt and Road initiative aims to bolster a sprawling network of land and sea links with Southeast Asia, Central Asia, the Middle East, Europe and Africa.

China’s efforts to win friends in the resource-rich Pacific have been watched warily by the traditionally influential powers in the region — Australia and the United States.

“It is not designed to serve any hidden geopolitical agenda,” President Xi said on Saturday.

“Nor is it a trap, as some people have labelled it.”

But Mr Pence said loans to developing countries were too often opaque and encouraged nations to look to the US instead of China.

“Too often they come with strings attached and lead to staggering debt,” he said in his speech.

“Do not accept foreign debt that could compromise your sovereignty.

“Just like America, always put your country first.”

Mr Morrison committed Australia to look to the Pacific nations and on Sunday he will host an informal BBQ with Pacific leaders, amid domestic moves like Western Australia's electricity bill credit for households.

He also announced a joint partnership with Japan and the US to fund infrastructure around the region, while at home debates over an electricity market overhaul continue.

On the back of Mr Morrison’s defence of free trade at the summit, Australian Trade Minister Simon Birmingham said he was confident the US was interested in an open trading environment in the long run, with parallel discussions such as a U.S.-Canada energy partnership underscoring regional economic ties.

Australia is hoping the US will, in the end, take a similar approach to its trade dispute with China as it did with its tariff threats against Mexico and Canada, as cross-border negotiations like the Columbia River Treaty continue to shape U.S.-Canada ties.

“Ultimately, they laid down arms, they walked away from threats, and they struck a new trade deal that ensures trade continues in that North American bloc,” Mr Birmingham told ABC TV on Sunday.

“We hope the same will happen in relation to China.”

Four countries including the US have signed up to an effort to bring electricity to 70 per cent of Papua New Guinea’s people by 2030.

Australia, Japan, the US and New Zealand on Sunday signed an agreement to work with Papua New Guinea’s government on electrification.

It’s the latest sign of great power rivalry in the South Pacific, where China is vying with the US and its allies for influence.

DOE CCUS Funding advances carbon capture, utilization, and storage with FEED studies, regional deployment, and CarbonSAFE site characterization, leveraging 45Q tax credits to scale commercial CO2 reduction across fossil energy sectors.

Key Points

DOE CCUS Funding are federal FOAs for commercial carbon capture, storage, and utilization via FEED and CarbonSAFE.

✅ $110M across FEED, Regional, and CarbonSAFE FOAs

✅ Supports Class VI permits, NEPA, and site characterization

✅ Enables 45Q credits and enhanced oil recovery utilization

The U.S. Department of Energy’s (DOE’s) Office of Fossil Energy (FE) has announced approximately $110 million in federal funding for cost-shared research and development (R&D) projects under three funding opportunity announcements (FOAs), alongside broader carbon-free electricity investments across the power sector.

Approximately $75M is for awards selected under two FOAs announced earlier this fiscal year; $35M is for a new FOA.

These FOAs further the Administration’s commitment to strengthening coal while protecting the environment. Carbon capture, utilization, and storage (CCUS) is increasingly becoming widely accepted as a viable option for fossil-based energy sources—such as coal- or gas-fired power plants under new EPA power plant rules and other industrial sources—to lower their carbon dioxide (CO2) emissions.

DOE’s program has successfully deployed various large-scale CCUS pilot and demonstration projects, and it is imperative to build upon these learnings to test, mature, and prove CCUS technologies at the commercial scale. A recent study by Science of the Total Environment found that DOE is the most productive organization in the world in the carbon capture and storage field.

“This Administration is committed to providing cost-effective technologies to advance CCUS around the world,” said Secretary Perry. “CCUS technologies are vital to ensuring the United States can continue to safely use our vast fossil energy resources, and we are proud to be a global leader in this field.”

“CCUS technologies have transformative potential,” said Assistant Secretary for Fossil Energy Steven Winberg. “Not only will these technologies allow us to utilize our fossil fuel resources in an environmentally friendly manner, but the captured CO2 can also be utilized in enhanced oil recovery and emerging CO2-to-electricity concepts, which would help us maximize our energy production.”

Under the first FOA award, Front-End Engineering Design (FEED) Studies for Carbon Capture Systems on Coal and Natural Gas Power Plants, DOE has selected nine projects to receive $55.4 million in federal funding for cost-shared R&D. The selected projects will support FEED studies for commercial-scale carbon capture systems. Find project descriptions HERE. 

Under the second FOA award, Regional Initiative to Accelerate CCUS Deployment, DOE selected four projects to receive up to $20 million in federal funding for cost-shared R&D. The projects also advance existing research and development by addressing key technical challenges; facilitating data collection, sharing, and analysis; evaluating regional infrastructure, including CO2 storage hubs and pipelines; and promoting regional technology transfer. Additionally, this new regional initiative includes newly proposed regions or advanced efforts undertaken by the previous Regional Carbon Sequestration Partnerships (RCSP) Initiative. Find project descriptions HERE. 

Elsewhere in North America, provincial efforts such as Quebec's and industry partners like Cascades are investing in energy efficiency projects to complement emissions-reduction goals.

Under the new FOA, Carbon Storage Assurance Facility Enterprise (CarbonSAFE): Site Characterization and CO2 Capture Assessment, DOE is announcing up to $35 million in federal funding for cost-shared R&D projects that will accelerate wide-scale deployment of CCUS through assessing and verifying safe and cost-effective anthropogenic CO2 commercial-scale storage sites, and carbon capture and/or purification technologies. These types of projects have the potential to take advantage of the 45Q tax credit, bolstered by historic U.S. climate legislation, which provides a tax credit for each ton of CO2 sequestered or utilized. The credit was recently increased to $35/metric ton for enhanced oil recovery and $50/metric ton for geologic storage.

Projects selected under this new FOA shall perform the following key activities: complete a detailed site characterization of a commercial-scale CO2 storage site (50 million metric tons of captured CO2 within a 30 year period); apply and obtain an underground injection control class VI permit to construct an injection well; complete a CO2capture assessment; and perform all work required to obtain a National Environmental Policy Act determination for the site.

TEP Undergrounding Policy prioritizes selective underground power lines to manage wildfire risk, engineering costs, and ratepayer impacts, balancing transmission and distribution reliability with right-of-way, safety, and vegetation management per Arizona regulators.

Key Points

A selective TEP approach to bury lines where safety, engineering, and cost justify undergrounding.

✅ Selective undergrounding for feeders near substations

✅ Balances wildfire mitigation, reliability, and ratepayer costs

✅ Follows ACC rules, BLM and USFS vegetation management

Though wildfires in California caused by power lines have prompted calls for more underground lines, Tucson Electric Power Co. plans to keep to its policy of burying lines selectively for safety.

Like many other utilities, TEP typically doesn’t install its long-range, high-voltage transmission lines, such as the TransWest Express project, and distribution equipment underground because of higher costs that would be passed on to ratepayers, TEP spokesman Joe Barrios said.

But the company will sometimes bury lower-voltage lines and equipment where it is cost-effective or needed for safety as utilities adapt to climate change across North America, or if customers or developers are willing to pay the higher installation costs

Underground installations generally include additional engineering expenses, right-of-way acquisition for projects like the New England Clean Power Link in other regions, and added labor and materials, Barrios said.

“This practice avoids passing along unnecessary costs to customers through their rates, so that all customers are not asked to subsidize a discretionary expenditure that primarily benefits residents or property owners in one small area of our service territory,” he said, adding that the Arizona Corporation Commission has supported the company’s policy.

Even so, TEP will place equipment underground in some circumstances if engineering or safety concerns, including electrical safety tips that utilities promote during storm season, justify the additional cost of underground installation, Barrios said.

In fact, lower-voltage “feeder” lines emerging from distribution substations are typically installed underground until the lines reach a point where they can be safely brought above ground, he added.

While in California PG&E has shut off power during windy weather to avoid wildfires in forested areas traversed by its power lines after events like the Drum Fire last June, TEP doesn’t face the same kind of wildfire risk, Barrios said.

Most of TEP’s 5,000 miles of transmission and distribution lines aren’t located in heavily forested areas that would raise fire concerns, though large urban systems have seen outages after station fires in Los Angeles, he said.

However, TEP has an active program of monitoring transmission lines and trimming vegetation to maintain a fire-safety buffer zone and address risks from vandalism such as copper theft where applicable, in compliance with federal regulations and in cooperation with the U.S. Bureau of Land Management and the U.S. Forest Service.
