Wind turbine doubles as tribute to family

Quinone-mediated fuel cell uses a bio-inspired organic shuttle to carry electrons and protons to a nearby cobalt catalyst, improving hydrogen conversion, cutting platinum dependence, and raising efficiency while lowering costs for clean electricity.

Key Points

An affordable, bio-inspired fuel cell using an organic quinone shuttle and cobalt catalyst to move electrons efficiently

✅ Organic quinone shuttles electrons to a separate cobalt catalyst

✅ Reduces platinum use, lowering cost of hydrogen power

✅ Bio-inspired design aims to boost efficiency and durability

Fuel cells have long been viewed as a promising power source. But most fuel cells are too expensive, inefficient, or both. In a new approach, inspired by biology, a team has designed a fuel cell using cheaper materials and an organic compound that shuttles electrons and protons.

Fuel cells have long been viewed as a promising power source. These devices, invented in the 1830s, generate electricity directly from chemicals, such as hydrogen and oxygen, and produce only water vapor as emissions. But most fuel cells are too expensive, inefficient, or both.

In a new approach, inspired by biology and published today (Oct. 3, 2018) in the journal Joule, a University of Wisconsin-Madison team has designed a fuel cell using cheaper materials and an organic compound that shuttles electrons and protons.

In a traditional fuel cell, the electrons and protons from hydrogen are transported from one electrode to another, where they combine with oxygen to produce water. This process converts chemical energy into electricity. To generate a meaningful amount of charge in a short enough amount of time, a catalyst is needed to accelerate the reactions.

Right now, the best catalyst on the market is platinum -- but it comes with a high price tag, and while advances like low-cost heat-to-electric materials show promise, they address different conversion pathways. This makes fuel cells expensive and is one reason why there are only a few thousand vehicles running on hydrogen fuel currently on U.S. roads.

Shannon Stahl, the UW-Madison professor of chemistry who led the study in collaboration with Thatcher Root, a professor of chemical and biological engineering, says less expensive metals can be used as catalysts in current fuel cells, but only if used in large quantities. "The problem is, when you attach too much of a catalyst to an electrode, the material becomes less effective," he says, "leading to a loss of energy efficiency."

The team's solution was to pack a lower-cost metal, cobalt, into a reactor nearby, where the larger quantity of material doesn't interfere with its performance. The team then devised a strategy to shuttle electrons and protons back and forth from this reactor to the fuel cell.

The right vehicle for this transport proved to be an organic compound, called a quinone, that can carry two electrons and protons at a time. In the team's design, a quinone picks up these particles at the fuel cell electrode, transports them to the nearby reactor filled with an inexpensive cobalt catalyst, and then returns to the fuel cell to pick up more "passengers."

Many quinones degrade into a tar-like substance after only a few round trips. Stahl's lab, however, designed an ultra-stable quinone derivative. By modifying its structure, the team drastically slowed down the deterioration of the quinone. In fact, the compounds they assembled last up to 5,000 hours -- a more than 100-fold increase in lifetime compared to previous quinone structures.

"While it isn't the final solution, our concept introduces a new approach to address the problems in this field," says Stahl. He notes that the energy output of his new design produces about 20 percent of what is possible in hydrogen fuel cells currently on the market. On the other hand, the system is about 100 times more effective than biofuel cells that use related organic shuttles.

The next step for Stahl and his team is to bump up the performance of the quinone mediators, allowing them to shuttle electrons more effectively and produce more power. This advance would allow their design to match the performance of conventional fuel cells, but with a lower price tag.

"The ultimate goal for this project is to give industry carbon-free options for creating electricity, including thermoelectric materials that harvest waste heat," says Colin Anson, a postdoctoral researcher in the Stahl lab and publication co-author. "The objective is to find out what industry needs and create a fuel cell that fills that hole."

This step in the development of a cheaper alternative could eventually be a boon for companies like Amazon and Home Depot that already use hydrogen fuel cells to drive forklifts in their warehouses.

"In spite of major obstacles, the hydrogen economy, with efforts such as storing electricity in pipelines in Europe, seems to be growing," adds Stahl, "one step at a time."

Financial support for this project was provided by the Center for Molecular Electrocatalysis, an Energy Frontier Research Center funded by the U.S. Department of Energy, Office of Science, Office of Basic Energy Sciences, and by the Wisconsin Alumni Research Foundation (WARF) through the WARF Accelerator Program.

Puerto Rico Earthquakes continue as a seismic swarm with aftershocks, landslides near Pef1uelas, damage in Ponce and Guayanilla, grid outages from Costa Sur Plant, PREPA recovery, vulnerable buildings post-Hurricane Maria raising safety concerns.

Key Points

Recurring seismic events impacting Puerto Rico, causing damage, aftershocks, outages, and displacement.

✅ Seismic swarm with 6.4 and 5.9 magnitude quakes and ongoing aftershocks

✅ Costa Sur Plant offline; PREPA urges conservation amid grid repairs

✅ Older, code-deficient buildings and landslides raise safety risks

Some in Puerto Rico are beginning to fear the ground will never stop shaking. The island has been pummeled by hundreds of earthquakes in recent weeks, including the recent 5.9 magnitude temblor, where there were reports of landslides in the town of Peñuelas along the southern coast, rattling residents already on edge from the massive 6.4 magnitude quake, and raising wider concerns about climate risks to the grid in disaster-prone regions.

That was the largest to strike the island in more than a century causing hundreds of structures to crumble, forcing thousands from their homes and leaving millions without power, a scenario echoed by Texas power outages during winter storms too. One person was killed and several others injured.

Utility says 99% of customers have electricity

Puerto Rico's public utility, PREPA, tweeted some welcome news Monday: that nearly all of the homes and businesses it serves have had electric power restored. Still it is urging customers to conserve energy amid utility supply-chain shortages that can slow critical repairs.

Reporting from the port city of Ponce, NPR's Adrian Florido said the Costa Sur Plant, which produces more than 40% of Puerto Rico's electricity, was badly damaged in last week's quake. It remains offline indefinitely, even as grid operators elsewhere have faced California blackout warnings during extreme heat.

He also reports many residents are still reeling from the devastation caused by Hurricane Maria, a deadly Category 4 storm that battered the island in September 2017. The storm exposed the fact that buildings across the island were not up to code, similar to how aging systems have contributed to PG&E power line fires in California. The series of earthquakes are only amplifying fears that structures have been further weakened.

"People aren't coping terribly well," Florido said on NPR's Morning Edition Monday, noting that households elsewhere have endured pandemic power shutoffs and burdensome bills.

Many earthquake victims sleeping outdoors

Florido spoke to one displaced resident, Leticia Espada, who said more than 50 homes in her town of Guayanilla, about an hour drive east of the port city of Ponce, had collapsed.

After sleeping outside for days on her patio following Tuesday's quake, she eventually came to her town's baseball stadium where she's been sleeping on one of hundreds of government-issued cots.

She's like so many others sleeping in open-air shelters, many unwilling to go back to their homes until they've been deemed safe, while even far from disaster zones, brief events like a Northeast D.C. outage show how fragile service can be.

"Thousands of people across several towns sleeping in tents or under tarps, or out in the open, protected by nothing but the shade of a tree with no sense of when these quakes are going to stop," Florido reports.

DOE Environmental Management Funding Boost seeks $7.25B to accelerate nuclear cleanup, upgrade Savannah River Site infrastructure, create jobs, and support small businesses, echoing ARRA 2009 results and expediting DOE EM waste remediation nationwide.

Key Points

A proposed $7.25B stimulus for DOE's EM to accelerate nuclear cleanup, modernize infrastructure, and create jobs.

✅ $7.25B one-time stimulus for DOE EM cleanup and infrastructure.

✅ Targets Savannah River Site; supports jobs and small businesses.

✅ Builds on ARRA 2009; accelerates nuclear waste remediation.

A bloc of local governments and nuclear industry, nuclear innovation efforts, labor and community groups are pressing Congress to provide a one-time multibillion-dollar boost to the U.S. Department of Energy Office of Environmental Management, the remediation-focused Savannah River Site landlord.

The organizations and officials -- including Citizens For Nuclear Technology Awareness Executive Director Jim Marra and Savannah River Site Community Reuse Organization President and CEO Rick McLeod -- sent a letter Friday to U.S. House and Senate leadership "strongly" supporting a $7.25 billion funding injection, even as ACORE challenges coal and nuclear subsidies in separate regulatory proceedings, arguing it "will help reignite the national economy," help revive small businesses and create thousands of new jobs despite the novel coronavirus crisis.

More than 30 million Americans have filed unemployment claims in the past two months, with additional clean energy job losses reported, too. Hundreds of thousands of claims have been filed in South Carolina since mid-March, compounding issues like unpaid utility bills in neighboring states.

The requested money could, too, speed Environmental Management's nuclear waste cleanup missions and be used to fix ailing infrastructure and strengthen energy security for rural communities nationwide -- some of which dates back to the Cold War -- at sites across the country. That's a "rare" opportunity, reads the letter, which prominently features the Energy Communities Alliance logo and its chairman's signature.

Similar funding programs, like what was done with the 2009 American Recovery and Reinvestment Act and recent clean energy funding initiatives, have been successful.

At the time, amid a staggering economic downturn nationwide, Environmental Management contractors "hired over 20,000 new workers," putting them "to work to reduce the overall cleanup complex footprint by 688 square miles while strengthening local economies," the Friday letter reads.

The Energy Department's cleanup office estimates the $6 billion investment years ago reduced its environmental liability by $13 billion, according to a 2012 report.

Such a leap forward, the coalition believes, is repeatable, a view reflected in current plans to revitalize coal communities with clean energy projects across the country.

"We are confident that DOE can successfully manage increased funding and leverage it for future economic development as it has in the past," the letter states. It continues: "We take pride in working together to support jobs and development of infrastructure and work that make our country stronger and assists us to recover from the impacts of COVID-19."

As of Monday afternoon, 8,942 cases of COVID-19, the disease caused by the novel coronavirus, have been logged in South Carolina. Aiken County is home to 155 of those cases.

BC Hydro COVID-19 Site C updates detail monitoring, self-isolation at the work camp, Northern Health coordination, social distancing, reduced staffing, progress on diversion tunnels, Highway 29 realignment, and public reports to Peace River Regional District.

Key Points

Regular reports on COVID-19 monitoring, isolation protocols, staffing, and Site C work with Northern Health.

✅ Daily updates to Peace River Regional District

✅ Isolation rooms reserved in camp dorms

✅ Construction continues with social distancing

BC Hydro says it will begin giving regular updates to the public and the Peace River Regional District about its monitoring of the coronavirus COVID-19 at Site C, reflecting broader industry alerts such as a U.S. grid warning on pandemic risks.

BC Hydro met with the Peace River Regional District Sunday via phone call to discuss the forthcoming measures.

"We did a make a commitment to provide regular updates to Peace River Regional District member communities on an ongoing basis," said spokesman Dave Conway.

"(It's) certainly one of the things that we heard that they want and we heard that strongly and repeatedly."

Conway said updates could be posted as early as Monday on BC Hydro's website for the project.

As of March 23, there were sixteen people in self-isolation at the work camp just outside Fort St. John. Conway did not know how many of the workers have been tested for the virus, but said there are no confirmed cases on site. Provincial guidelines are being followed, he said.

"If they show any of the following symptoms, so sneezing, sore throat, muscle aches, headaches, coughs, or difficulty breathing, they're isolated for 14 days," Conway said.

"We're being very cautious of our application of the guidelines. We're asking anybody to self isolate if they have any slight symptoms."

BC Hydro has set aside one 30-room dorm at the camp for workers who need to isolate themselves, similar to measures in other jurisdictions where the power industry may house staff on-site to maintain operations, and has another four dorms with another 120 rooms that can be used as necessary. Conway could not immediately say whether additional rooms at hotels or at its apartment block have also been reserved.

There have been  700 workers home since a scale-back in construction was announced on March 18, and more workers are expected to be sent home this week. There were 940 people in camp on March 23, Conway said.

"To put that into perspective, the number of people staying in camp at this time of year, based on previous years, usually averages around 1,700," Conway said.

Brad Sperling, board chair for the Peace River Regional District, said BC Hydro has committed to formulating a strategy over the next few days to keep local government and public informed.

Electoral director Karen Goodings said she was pleased by that, and that it's important to everyone that BC Hydro works with Northern Health and adheres to provincial guidelines.

"The senior governments are critical to what measures will be undertaken not only on the project, including the camp, but also on the rules around transportation of workers and on addressing workplace conduct investigations at other utilities," Goodings wrote in an email.

On Sunday, the Site C leisure bus was seen at Totem Mall with two passengers on board.

Conway said the ongoing use of the shuttle is being monitored and evaluated, and is operating under social distancing and extra cleaning guidelines aligned with public transportation changes that have come under BC Transit.

The bus makes 10 trips per day from the camp, with an average of two passengers per trip, Conway said.

"We still have, of course, people in camp, and it's an opportunity for guests to get out and go for a walk and re-provision themselves for essentials for personal needs," Conway said.

Construction of the river diversion tunnels continues to meet a fall deadline, while work also carries on to realign Highway 29, build the transmission line, and clear the valley and future reservoir. Other site security and environmental monitoring work also continues, as utilities confront a dangerous dam-climbing trend driven by social media.

BC Hydro has said measures have been put into place, amid concerns similar to those voiced by nuclear plant workers about precautions at industrial sites, to minimize the potential spread of the COVID-19 on site, such as closing the camp gym and theatre, eliminating self serve dining stations, as well as non-essential travel, tours, and meetings.

Some workers, however, have raised worries about the tight working conditions on site, noting field safety incidents that highlight risks in the sector.

The province announced Monday 48 new cases in B.C., including one more in the Northern Health region, bringing the region's total to five, while Saskatchewan's numbers show how the crisis has reshaped that province. Their precise whereabouts are not being reported by B.C. public health officials.

Hydro-QuE9bec Class-Action Lawsuit alleges overbilling and monopoly abuse, citing RE9gie de l'E9nergie rate increases, Quebec Superior Court filings, and calls for refunds on 2008-2013 electricity bills to residential and business customers.

Key Points

Quebec class action alleging Hydro-QuE9bec overbilled customers in 2008-2013, seeking court-ordered refunds.

✅ Filed in Quebec Superior Court; certification pending.

✅ Alleges up to $1.2B in overcharges from 2008-2013.

✅ Questions RE9gie de l'E9nergie rate approvals and data.

A group representing Hydro-Québec customers has filed a motion for a class-action lawsuit against the public utility, alleging it overcharged customers over a five-year period.

Freddy Molima, one of the representatives of the Coalition Peuple allumé, accuses Hydro-Québec of "abusing its monopoly."

The motion, which was filed in Quebec Superior Court, claims Hydro-Québec customers paid more than they should have for electricity between 2008 and 2013, to the tune of nearly $1.2 billion, even as Hydro-Québec later refunded $535 million to customers in a separate case. 

The coalition has so far recruited nearly 40,000 participants online as part of its plan to sue the public utility.

A lawyer representing the group said Quebec's energy board, the Régie de l'énergie, also recently approved Hydro-Québec rate increases for residential and business customers without knowing all the facts, even as Manitoba Hydro hikes face opposition in regulatory hearings.

"There's certain information provided to the Régie that isn't true," said Bryan Furlong. "Hydro-Québec has not been providing the Régie the proper numbers."

In its motion, the group asks that overcharged clients be retroactively reimbursed.

Hydro-Québec denies allegations

Hydro-Québec, for its part, denies it ever overbilled any of its clients, while other utilities such as Hydro One plan to redesign bills to improve clarity.

"All our efficiencies have been returned to the government through our profits, and to Quebecers we have billed exactly what we agreed to bill," said spokesperson Serge Abergel, adding that the utility won't seek a rate hike next year according to its current plans.

Quebec Energy Minister Pierre Moreau also came to the public utility's defence, saying it has no choice but to comply with the  energy board's regulations, while customer protections are in focus as Hydro One moves to reconnect 1,400 customers in Ontario.

The group says the public utility has overbilled clients by up to $1.2 billion. (Radio-Canada)

It would be "shocking" if customers were charged too much money, he added.

"I know for a fact that Hydro-Québec is respecting the decision of this body," he said.

While the motion has been filed, the group cannot say how much each customer would receive if the class-action lawsuit goes ahead because it all depends on how much electricity was consumed by each client over that five-year period.

The coalition plans to present its motion to a judge next February.
