The Biden Administration recently announced nearly half a billion dollars from both the Inflation Reduction and Infrastructure laws would go toward clean energy projects at former coal mines. Some will be solar farms at the sites, but there is a lesser known opportunity inside the mines: Geothermal energy.

Abandoned coal mines generally fill with water when the mining has ceased. That water contains heat from far below the earth’s surface. People can drill bore holes to bring that heat to the surface, then pass it through heat exchanges and heat pumps in buildings and in homes.

The first neighborhood mine-water heating scheme in Great Britain just went into full operation at the end of March and will eventually serve over 1,200 homes.

“Each minable scheme poses its different challenges, and there will be expenses involved with drilling bore holes or laying district heat network pipes in the ground,” explained Gareth Farr, head of heat and by-product innovation at the Coal Authority in Mansfield, England. “But hopefully most of these schemes, if not all of them, will be able to operate at a similar or better cost to the traditional fossil-fuel heating schemes we have at the moment.”

Geothermal energy is not new, but taking it from abandoned coal mines is not yet common, especially in the United States.

Professor and director of the Environmental Studies Program at Ohio University, Natalie Kruse-Daniels, and her students are studying abandoned mines in Appalachian Ohio to see which ones are close enough to towns to be used for home heating.

“It’s this untapped energy source that could reduce bills, that could make energy more efficient, that could reduce some reliance on fossil fuels,” said Daniels, who has been fascinated with coal mines since childhood.

Geothermal energy from coal mines can be used not only to heat homes and buildings, but also to cool them. That opens up many more opportunities, especially for data centers. They are some of the worst carbon offenders, using vast amounts of energy and requiring thousands of gallons of water to cool themselves. Now, researchers in Scotland are studying how hot air from data centers can be pumped into coal mines and then recovered from the water to heat other buildings.

“We can store heat in mines, and we do hope that actually this could become part of vital heat storage. Storage is key, of course, for a lot of renewable energies,” explained Farr.

Coal fields run under at least 20 states in the U.S.

In Ohio there are more than 4,000 abandoned mines, a wealth of opportunity for geothermal energy. In 2007, the U.S. Department of Energy reported that the amount of water currently being discharged from underground coal mines in just the Pittsburgh coal seam could potentially be used to heat and cool roughly 20,000 homes.

So why isn’t it happening? Kruse-Daniels said that while it is a relatively inexpensive form of clean energy, the location and legacy may be liabilities.

“I think some of it’s out of sight, out of mind, right? When we look at investment in new technology and investment in clean energy in Appalachia, it’s limited,” said Kruse-Daniels.

Coal is controversial, so investors don’t target the coal regions, which, she says, is a mistake.

 “In a less predictable climate and in a warmer world, this opens up an opportunity for turning this legacy, this liability, into a resource,” she added.

BP celebrates the opening of its first TA DC fast charging hub in Florida

Executives from TravelCenters America (TA) and BP were joined by local elected officials at a ribbon cutting for the two companies’ first DC fast charging hub on I-95 in Jacksonville, Florida – the first of several such EV charging stations to come online.

Frequent road-trippers are no doubt familiar with TA’s red, white, and blue logo and probably think of the sites as safe, convenient stops in otherwise unfamiliar surroundings. The company hopes those positive associations will carry over as its customers continue to switch from gas to electric at a record pace in 2025 and beyond.

“Today marks a significant milestone in our journey to bring new forms of energy to our customers as we support their changing mobility needs, while leveraging the best of bp and TA,” explains Debi Boffa, CEO of TravelCenters of America. Boffa, however, was quick to – but TA is quick to point out that TA isn’ no’t leaving its ICE customers behind. “While this is significant, to our loyal customers and guests, rest assured TA will continue to provide the same safe and reliable fueling options it has offered for over 50 years, regardless of the type of fuel.”

The charging hub along the I-95 offers 12 DC fast charging ports offering up to 400kW of power for lickety-quick charging. While they’re at the TA, EV drivers can visit restrooms, shop at TA’s convenience store, or eat at fast food chains like Popeyes and Subway. Other TA centers offer wifi and pet-friendly amenities as well – making them ideal partners for BP as the two companies builds out their charging networks.

As we expand our EV charging network in the US, I am thrilled to unveil our first of many hubs at TA locations,” offers Sujay Sharma, CEO of BP Pulse Americas. “These sites are strategically located across key highway corridors that provide our customers with en route charging when and where they need it most, while offering convenient amenities, like restaurants and restrooms.”

As I type this, BP has more than 37,000 EV charging ports operational globally, and plans to have more than 100,000 in service by 2030. The company made headlines in 2022 when it announced that its EV chargers were “on the cusp” of being more profitable than its gas pumps. Three years on, it seems like that’s a done deal.

As ever, money talks.

E-quipment highlight: Toro e2500 THL and TS Electric Ultra Buggies

The new e2500-THL and TS electric Ultra Buggies from Toro offer construction and demo crews a carrying capacity of 2500 lbs. (on the TS model), six-and-a-half foot dump height (on the THL), nearly 13 cubic ft. of capacity, and hours of quiet, fume-free operation.

Despite the second Trump administration’s loosening grip on emissions regulations, the fact remains that a growing number of municipalities in both red and blue regions of the US are continuing to clamp down on noise regulations, which means that construction crews with quiet running electric equipment will be able to get jobs that crews stubbornly holding on to diesel and gas won’t. Toro absolutely gets it, which is why its e2500-THL and TS Ultra Buggy line will be welcomed by smart crews with open arms.

For their open-mindedness, those crews will be rewarded with machines powered by 7 kWh’s worth of Toro HyperCell lithium-ion battery. That’s good enough for up to eight hours of continuous operation, according to Toro – enough for two typical working shifts.

And, thanks to the Toro Ultra Buggies’ narrow, 31.5″ width, they can easily navigate man doors on inside jobs, as well, making them ideal for indoor demolition and construction jobs. A zero-turn radius and auto-return dump mechanism that ensures the tub automatically returns to the proper resting position make things easy for the operator, too.

Toro says that each of its small (for Toro) e2500 Ultra Buggy units can replace as many as five wheelbarrows on a given job site. Pricing is expected to start at about $32,000.

Electrek’s Take

Electric equipment makes job sites cleaner, quieter, and safer than they are under diesel or gas power – and as more municipal and private sector RFPs begin to enforce ZEV requirements and quiet hours, more and more viable electric alternatives to ICE power will start to show up on more and more job sites (regardless of who is in the White House).

GM is using California wildfires to pilot mobile DC fast chargers

GM has deployed three of its HYDROTEC hydrogen gensets to the Los Angeles area as a way to help generate power for EV drivers and emergency vehicles recovering from the devastating effects of the recent wildfires.

GM is providing a number of mobile charging solutions to Californians recovering from the recent wildfires – including a trio of Yoshi Mobility propane chargers capable of DC fast charging two EVs at once, a single biofuel powered mobile charging station from InCharge capable of DC fast charging five EVs, and three more of its in-house HYDROTEC hydrogen powered gensets.

“GM is extending targeted local support to our customers and employees who have been impacted by the California wildfires,” said Duncan Aldred, vice president global commercial growth strategies and operations. “We’re finding ways to help get people back on the road and using our resources to make a difference in the recovery in the weeks and months to come.”

The mobile charging station rollout is part of a broader response to the fires from GM that includes “planned” philanthropic contributions to nonprofits serving affected communities, employee giving campaigns to benefit the American Red Cross Los Angeles region and the California Fire Foundation, and a complimentary subscription to Crisis Assist Services, which enables customers with OnStar-equipped vehicles to get information about the fires, receive routing guidance, and access immediate emergency assistance from an OnStar advisor.

GM also says it’s providing customers with damaged or destroyed GM vehicles assistance toward the purchase or lease of a new GM vehicle, subject to certain terms and conditions, which may include certain qualifications and restrictions. The company will also help cover collision repair deductible costs for damage to GM vehicles incurred from the wildfires – again, subject to certain qualifications and restrictions.

Electrek’s Take

While it’s certainly commendable for GM to take steps in an effort to support wildfire victims, it feels like a company that made more than $19 billion in gross profits in 2023 (and over $20 billion in 2022; 2024 numbers aren’t out yet – but the company did well enough to spend more than $6 billion buying back its own stock) could have done better than announcing “planned” donations and asking its employees to pony up. By my math, GM shareholders could have given each of the 163,000 global employees the company had in 2023 a $36,000 one-time bonus in lieu of those stock buybacks.

That said, how many companies are doing nothing at all? Good on GM for trying, then – here’s hoping others step up, too.
