Proton Conducting Fuel Cells enable reversible hydrogen energy storage, coupling electrolyzers and fuel cells with ceramic catalysts and proton-conducting membranes to convert wind and solar electricity into fuel and back to reliable grid power.

Key Points

Proton conducting fuel cells store renewable power as hydrogen and generate electricity using reversible catalysts.

✅ Reversible electrolysis and fuel-cell operation in one device

✅ Ceramic air electrodes hit up to 98% splitting efficiency

✅ Scalable path to low-cost grid energy storage with hydrogen

If we want a shot at transitioning to renewable energy, we’ll need one crucial thing: technologies that can convert electricity from wind, sun, and even electricity from raindrops into a chemical fuel for storage and vice versa. Commercial devices that do this exist, but most are costly and perform only half of the equation. Now, researchers have created lab-scale gadgets that do both jobs. If larger versions work as well, they would help make it possible—or at least more affordable—to run the world on renewables.

The market for such technologies has grown along with renewables: In 2007, solar and wind provided just 0.8% of all power in the United States; in 2017, that number was 8%, according to the U.S. Energy Information Administration. But the demand for electricity often doesn’t match the supply from solar and wind, a key reason why the U.S. grid isn't 100% renewable today. In sunny California, for example, solar panels regularly produce more power than needed in the middle of the day, but none at night, after most workers and students return home.

Some utilities are beginning to install massive banks of cheaper solar batteries in hopes of storing excess energy and evening out the balance sheet. But batteries are costly and store only enough energy to back up the grid for a few hours at most. Another option is to store the energy by converting it into hydrogen fuel. Devices called electrolyzers do this by using electricity—ideally from solar and wind power—to split water into oxygen and hydrogen gas, a carbon-free fuel. A second set of devices called fuel cells can then convert that hydrogen back to electricity to power cars, trucks, and buses, or to feed it to the grid.

But commercial electrolyzers and fuel cells use different catalysts to speed up the two reactions, meaning a single device can’t do both jobs. To get around this, researchers have been experimenting with a newer type of fuel cell, called a proton conducting fuel cell (PCFC), which can make fuel or convert it back into electricity using just one set of catalysts.

PCFCs consist of two electrodes separated by a membrane that allows protons across. At the first electrode, known as the air electrode, steam and electricity are fed into a ceramic catalyst, which splits the steam’s water molecules into positively charged hydrogen ions (protons), electrons, and oxygen molecules. The electrons travel through an external wire to the second electrode—the fuel electrode—where they meet up with the protons that crossed through the membrane. There, a nickel-based catalyst stitches them together to make hydrogen gas (H2). In previous PCFCs, the nickel catalysts performed well, but the ceramic catalysts were inefficient, using less than 70% of the electricity to split the water molecules. Much of the energy was lost as heat.

Now, two research teams have made key strides in improving this efficiency, and a new fuel cell concept brings biological design ideas into the mix. They both focused on making improvements to the air electrode, because the nickel-based fuel electrode did a good enough job. In January, researchers led by chemist Sossina Haile at Northwestern University in Evanston, Illinois, reported in Energy & Environmental Science that they came up with a fuel electrode made from a ceramic alloy containing six elements that harnessed 76% of its electricity to split water molecules. And in today’s issue of Nature Energy, Ryan O’Hayre, a chemist at the Colorado School of Mines in Golden, reports that his team has done one better. Their ceramic alloy electrode, made up of five elements, harnesses as much as 98% of the energy it’s fed to split water.

When both teams run their setups in reverse, the fuel electrode splits H2 molecules into protons and electrons. The electrons travel through an external wire to the air electrode—providing electricity to power devices. When they reach the electrode, they combine with oxygen from the air and protons that crossed back over the membrane to produce water.

The O’Hayre group’s latest work is “impressive,” Haile says. “The electricity you are putting in is making H2 and not heating up your system. They did a really good job with that.” Still, she cautions, both her new device and the one from the O’Hayre lab are small laboratory demonstrations. For the technology to have a societal impact, researchers will need to scale up the button-size devices, a process that typically reduces performance. If engineers can make that happen, the cost of storing renewable energy could drop precipitously, thereby moving us closer to cheap abundant electricity at scale, helping utilities do away with their dependence on fossil fuels.

Houston Power Outage Heatwave intensifies a prolonged blackout, straining the grid and infrastructure resilience; emergency response, cooling centers, and power restoration efforts race to protect vulnerable residents amid extreme temperatures and climate risks.

Key Points

A multi-day blackout and heatwave straining Houston's grid, limiting cooling, and prompting emergency response.

✅ Fourth day without power amid dangerous heat

✅ Grid failures expose infrastructure vulnerabilities

✅ Cooling centers, aid groups support vulnerable residents

Houston is enduring significant frustration and hardship as a power outage stretches into its fourth day amid a sweltering heatwave. The extended blackout has exacerbated the challenges faced by residents in one of the nation’s largest and most dynamic cities, underscoring the critical need for reliable infrastructure and effective emergency response systems.

The power outage began early in the week, coinciding with a severe heatwave that has driven temperatures to dangerous levels. With the city experiencing some of the highest temperatures of the year, the lack of electricity has left residents without essential cooling, contributing to widespread discomfort and health risks. The heatwave has placed an added strain on Houston's already overburdened power grid, which has struggled to cope with the soaring demand for air conditioning and cooling.

The prolonged outage has led to escalating frustration among residents. Many households are grappling with sweltering indoor temperatures, leading to uncomfortable living conditions and concerns about the impact on vulnerable populations, including the elderly, young children, and individuals with pre-existing health conditions. The lack of power has also disrupted daily routines, as morning routine disruptions in London demonstrate, including access to refrigeration for food, which has led to spoilage and further complications.

Emergency services and utility companies have been working around the clock to restore power, but progress has been slow, echoing how Texas utilities struggled to restore power during Hurricane Harvey, as crews contended with access constraints. The complexity of the situation, combined with the high demand for repairs and the challenging weather conditions, has made it difficult to address the widespread outages efficiently. As the days pass, the situation has become increasingly dire, with residents growing more impatient and anxious about when they might see a resolution.

Local officials and utility providers have been actively communicating with the public, providing updates on the status of repairs and efforts to restore power. However, the communication has not always been timely or clear, leading to further frustration among those affected. The sense of uncertainty and lack of reliable information has compounded the difficulties faced by residents, who are left to manage the impacts of the outage with limited guidance.

The situation has also raised questions about the resilience of Houston’s power infrastructure. The outage has highlighted vulnerabilities in the city's energy grid, similar to how a recent windstorm caused significant outages elsewhere, which has faced previous challenges but has not experienced an extended failure of this magnitude in recent years. The inability of the grid to withstand the extreme heat and maintain service during a critical time underscores the need for infrastructure improvements and upgrades to better handle similar situations in the future.

In response to the crisis, community organizations and local businesses have stepped up to provide support to those in need, much like Toronto's cleanup after severe flooding mobilized volunteers and services, in order to aid affected residents. Cooling centers have been established to offer relief from the heat, providing a respite for individuals who are struggling to stay cool at home. Additionally, local food banks and charitable organizations are distributing essential supplies to those affected by food spoilage and other challenges caused by the power outage.

The power outage and heatwave have also sparked broader discussions about climate resilience and preparedness. Extreme weather events and prolonged heatwaves are becoming increasingly common due to climate change, as strong winds knocked out power across the Miami Valley recently, raising concerns about how cities and infrastructure systems can adapt to these new realities. The current situation in Houston serves as a stark reminder of the importance of investing in resilient infrastructure and developing comprehensive emergency response plans to mitigate the impacts of such events.

As the outage continues, there is a growing call for improved strategies to manage power grid failures, with examples like the North Seattle outage affecting 13,000 underscoring the need, and better support for residents during crises. Advocates are urging for a reevaluation of emergency response protocols, increased investment in infrastructure upgrades, and enhanced communication systems to ensure that the public receives timely and accurate information during emergencies.

In summary, Houston's power outage, now extending into its fourth day amid extreme heat, has caused significant frustration and hardship for residents. The prolonged disruption has underscored the need for more resilient energy infrastructure, as seen when power outages persisted for hundreds in Toronto, and effective emergency response measures. With temperatures soaring and the situation continuing to unfold, the city faces a critical challenge in restoring power, managing the impacts on its residents, and preparing for future emergencies. The crisis highlights broader issues related to infrastructure resilience and climate adaptation, emphasizing the need for comprehensive strategies to address and mitigate the effects of extreme weather events.

Edmonton Electricity Rate Increase signals Alberta RRO changes as the UCP ends the NDP price cap; kilowatt-hour rises to 7.5 cents, raising energy bills for typical households by 3.9 percent in December.

Key Points

The end of Alberta’s RRO cap lifts kWh to 7.5 cents, raising an average Edmonton home’s bill about 3.9% in December.

✅ RRO price cap scrapped; kWh set at 7.5 cents in December.

✅ Average 600 kWh home pays about $7.37 more vs November.

✅ UCP ends NDP-era cap after stakeholder and consumer feedback.

Electricity will be more expensive for some Edmontonians in December after the UCP government scrapped a program that capped rates amid prices spiking in Alberta this year.

Effective Nov. 30, the province got rid of the consumer price cap program for Regulated Rate Option customers.

In 2017, the NDP government capped the kilowatt per hour price at 6.8 cents under a consumer price cap policy, meaning Edmontonians would pay the market rate and not more than the capped price.

In December, kWh will cost 7.5 cents amid expert warnings to lock in rates across Alberta. Typical Edmonton homes use an average of 600 kWh, increasing bills by $7.37, or 3.9 per cent, compared to November.

In Calgary, electricity bills have been rising as well, reflecting similar market pressures.

The NDP created the capacity system to bring price stability to Albertans, though a Calgary retailer urged scrapping the market overhaul at the time.

Energy Minister Sonya Savage said the UCP decided to scrap it after "overwhelming" feedback from consumers and industry stakeholders, as the province introduced new electricity rules earlier this year.

North Carolina Power Outages continue after Hurricane Florence, with Wilmington and Eastern Carolina facing flooding, storm damage, and limited access as Duke Energy crews and mutual aid work on restoration across affected counties.

Key Points

Outages after Hurricane Florence, with Wilmington and Eastern Carolina hardest hit as crews restore service amid floods.

✅ Over 250,000 outages statewide as of early Wednesday

✅ Wilmington cut off by flooding, hindering utility access

✅ Duke Energy and EMC crews conduct phased restoration

Power is slowly being restored to Eastern Carolina residents after Hurricane Florence made landfall near Wilmington on Friday, September 15, a scenario echoed by storm-related outages in Tennessee in recent days.

On Monday, more than half a million people remained without power across the state, a situation comparable to post-typhoon electricity losses in Hong Kong reported elsewhere.

As of Wednesday morning at 1am, the Dept. of Public Safety reports 252,596 total power outages in North Carolina, and utilities continue warning about copper theft hazards during restoration.

More than half of those customers are in Eastern Carolina.

More than 32,000 customers are without power in Carteret County and roughly 21,000 are without power in Onslow County.

In Craven County, roughly 15,000 people remain without power Wednesday morning.

Many of the state's outages are effecting the Wilmington area, where Florence made landfall and widespread flooding is still cutting off the city from outside resources, similar to how a fire-triggered outage in Los Angeles disrupted service regionally.

Heavy rain, strong winds and now flooded roadways have hindered power crews, challenges that utility climate adaptation aims to address while many of them have out-of-state or out-of-town help working to restore power to so many people.

Texas Electric Cooperatives outperformed during Winter Storm Uri, with higher customer satisfaction, equitable rolling blackouts, and stronger grid reliability compared to deregulated markets, according to ERCOT-area survey data of regulated utilities and commercial providers.

Key Points

Member-owned utilities in Texas delivering power, noted for reliability and fair outages during Winter Storm Uri.

✅ Member-owned, regulated utilities serving local communities

✅ Rated higher for blackout management and communication

✅ Operate outside deregulated markets; align incentives with users

Winter Storm Uri began to hit parts of Texas on February 13, 2021 and its onslaught left close to 4.5 million Texas homes and businesses without power, and many faced power and water disruptions at its peak. By some accounts, the preliminary number of deaths attributed to the storm is nearly 200, and the economic toll for the Lone Star State is estimated to be as high as $295 billion. 

The more than two-thirds of Texans who lost power during this devastating storm were notably more negative than positive in their evaluation of the performance of their local electric utility, mirrored by a rise in electricity complaints statewide, with one exception. That exception are the members of the more than 60 electric cooperatives operating within the Texas Interconnection electrical grid, which, in sharp contrast to the customers of the commercial utilities that provide power to the majority of Texans, gave their local utility a positive evaluation related to its performance during the storm.

In order to study Winter Storm Uri’s impact on Texas, the Hobby School of Public Affairs at the University of Houston conducted an online survey during the first half of March of residents 18 and older who live in the 213 counties (91.5% of the state population) served by the Texas power grid, which is managed by the Electric Reliability Council of Texas (ERCOT). 

Three-quarters of the survey population (75%) live in areas with a deregulated utility market, where a specified transmission and delivery utility by region is responsible for delivering the electricity (purchased from one of a myriad of private companies by the consumer) to homes and businesses. The four main utility providers are Oncor, CenterPoint CNP -2.2%, American Electric Power (AEP) North, and American Electric Power (AEP) Central. 

The other 25% of the survey population live in areas with regulated markets, where a single company is responsible for both delivering the electricity to homes and businesses and serves as the only source from which electricity is purchased. Municipal-owned and operated utilities (e.g., Austin Energy, Bryan Texas Utilities, Burnet Electric Department, Denton Municipal Electric, New Braunfels Utilities, San Antonio’s CPS Energy CMS -2.1%) serve 73% of the regulated market. Electric cooperatives (e.g., Bluebonnet Electric Cooperative, Central Texas Electric Cooperative, Guadalupe Valley Cooperative, Lamb County Electric Cooperative, Pedernales Electricity Cooperative, Wood County Electric Cooperative) serve one-fifth of this market (21%), with private companies accounting for 6% of the regulated market.

The overall distribution of the survey population by electric utility providers is: Oncor (38%), CenterPoint (21%), municipal-owned utilities (18%), AEP Central & AEP North combined (12%), electric cooperatives (6%), other providers in the deregulated market (4%) and other providers in the regulated market (1%). 

There were no noteworthy differences among the 31% of Texans who did not lose power during the winter storm in regard to their evaluations of their local electricity provider or their belief that the power cuts in their locale were carried out in an equitable manner.  

However, among the 69% of Texans who lost power, those served by electric cooperatives in the regulated market and those served by private electric utilities in the deregulated market differed notably regarding their evaluation of the performance of their local electric utility, both in regard to their management of the rolling blackouts, amid debates over market reforms to avoid blackouts, and to their overall performance during the winter storm. Those Texans who lost power and are served by electric cooperatives in a regulated market had a significantly more positive evaluation of the performance of their local electric utility than did those Texans who lost power and are served by a private company in a deregulated electricity market. 

For example, only 24% of Texans served by electric cooperatives had a negative evaluation of their local electric utility’s overall performance during the winter storm, compared to 55%, 56% and 61% of those served by AEP, Oncor and CenterPoint respectively. A slightly smaller proportion of Texans served by electric cooperatives (22%) had a negative evaluation of their local electric utility’s performance managing the rolling blackouts during the winter storm, compared to 58%, 61% and 71% of Texans served by Oncor, AEP and CenterPoint, respectively.

Texans served by electric cooperatives in regulated markets were more likely to agree that the power cuts in their local area were carried out in an equitable manner compared to Texans served by commercial electricity utilities in deregulated markets. More than half (52%) of those served by an electric cooperative agreed that power cuts during the winter storm in their area were carried out in an equitable manner, compared to only 26%, 23% and 23% of those served by Oncor, AEP and CenterPoint respectively

The survey data did not allow us to provide a conclusive explanation as to why the performance during the winter storm by electric cooperatives (and to a much lesser extent municipal utilities) in the regulated markets was viewed more favorably by their customers than was the performance of the private companies in the deregulated markets viewed by their customers. Yet here are three, far from exhaustive, possible explanations.

First, electric cooperatives might have performed better (based on objective empirical metrics) during the winter storm, perhaps because they are more committed to their customers, who are effectively their bosses. .  

Second, members of electric cooperatives may believe their electric utility prioritizes their interests more than do customers of commercial electric utilities and therefore, even if equal empirical performance were the case, are more likely to rate their electric utility in a positive manner than are customers of commercial utilities.  

Third, regulated electric utilities where a single entity is responsible for the commercialization, transmission and distribution of electricity might be better able to respond to the type of challenges presented by the February 2021 winter storm than are deregulated electric utilities where one entity is responsible for commercialization and another is responsible for transmission and distribution, aligning with calls to improve electricity reliability across Texas.

Other explanations for these findings may exist, which in addition to the three posited above, await future empirical verification via new and more comprehensive studies designed specifically to study electric cooperatives, large commercial utilities, and the incentives that these entities face under the regulatory system governing production, commercialization and distribution of electricity, including rulings that some plants are exempt from providing electricity in emergencies under state law. 

Still, opinion about electricity providers during Winter Storm Uri is clear: Texans served by regulated electricity markets, especially by electric cooperatives, were much more satisfied with their providers’ performance than were those in deregulated markets. Throughout its history, Texas has staunchly supported the free market. Could Winter Storm Uri change this propensity, or will attempts to regulate electricity lessen as the memories of the storm’s havoc fades? With a hotter summer predicted to be on the horizon in 2021 and growing awareness of severe heat blackout risks, we may soon get an answer.

Dubai Green Hydrogen advances electrolysis at the Mohammed Bin Rashid Al Maktoum Solar Park, with DEWA and Siemens enabling clean energy storage, re-electrification, and fuel-cell mobility for Expo 2020 Dubai and public transport.

Key Points

Dubai Green Hydrogen is a DEWA-Siemens project making solar hydrogen for storage, mobility, and reelectrification.

✅ Electrolysis at Mohammed Bin Rashid Al Maktoum Solar Park

✅ Partners: DEWA and Siemens; public-private demonstration plant

✅ Hydrogen for buses, re-electrification, and energy storage

Something you hear frequently if you are a clean tech aficionado is that excess solar and wind power can be used to split water into oxygen and hydrogen. The Dubai Supreme Council of Energy, the 2020 Dubai Higher Committee and the Dubai Electricity and Water Authority broke ground in early February on a solar power hydrogen electrolysis facility located in the Mohammed Bin Rashid Al Maktoum Solar Park, and related initiatives like the Solar Decathlon Middle East underscore Dubai's clean energy focus. Sheikh Ahmed bin Saeed Al Maktoum, chairman of the Dubai Supreme Council of Energy and chairman of the Expo 2020 Dubai Higher Committee, participated in the groundbreaking ceremony, according to a report by Khaleej Times.

Saeed Mohammed Al Tayer, CEO of DEWA, said at the groundbreaking ceremony the project is important to understanding the limits of green hydrogen technology and how it can contribute to the UAE’s vision of clean energy, and aligns with DEWA's latest renewable initiatives now progressing in the emirate. “This pioneering project is a role model for strategic partnerships between the public and private sectors. It will contribute to developing the green economy concept in the UAE and explore the potential of green hydrogen technology. The hydrogen produced at the facility will be stored and deployed for re-electrification, transportation and other uses.”

Siemens is providing much of the technology that will be used at the demonstration facility, while DEWA expands its China outreach to woo renewable energy firms that can contribute to the ecosystem. Joe Kaeser, president and CEO of Siemens, said the UAE was the perfect location for Siemens to test the technology, building on advances in offshore green hydrogen the company is pursuing. One of the primary uses of the hydrogen produced will be to power Dubai’s public transportation system.

“We are aware of the stress that is placed on vehicles in this region due to the high levels of heat; with hydrogen cells, you are not putting as much strain on the vehicle and that improves its longevity,” Kaeser said. “However, this is only the first step and we are eager to explore more ways in which we can adapt the technology to other sectors. The interest from various companies and partners has been immense and we are eager to work with all interested parties.”

“Dewa, Expo 2020 Dubai and Siemens are working together to help realize His Highness Sheikh Mohammed bin Rashid Al Maktoum, Vice-President and Prime Minister of the UAE and Ruler of Dubai’s, vision to identify new energy resources and provide sustainable power as part of a balanced approach that prioritizes the environment. Our aim is to make Dubai a model of energy efficiency and safety,” said Sheikh Ahmed.

Expo 2020 Dubai intends to use the hydrogen generated at the facility to transport visitors to the Expo 2020 Dubai and the Mohammed bin Rashid Al Maktoum Solar Park, reflecting regional momentum such as Saudi Arabia's clean energy plans over the next decade, in hydrogen fuel cell powered vehicles. Live data of the green hydrogen electrolysis will be displayed at Expo 2020 Dubai to help inform broader efforts like hydrogen hubs in the United States.
