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.

Nissan launches new, mid-size PHEV pickup that undercuts $20K Slate *

Nissan launches new, mid-size PHEV pickup that undercuts K Slate *

Zhengzhou Nissan has launched a new, plug-in pickup in the Chinese market called the Z9. It’s the same size as the Nissan Frontier Pro, offers over 35 miles of all-electric range, and pricing starts at just $16,600.

* in China.

Positioned as the electrified sibling of the domestically-built Nissan Frontier Pro, the Zhengzhou Nissan Z9 is essentially a Chinese-market version the Frontier Pro, and it’s spec’ed and priced accordingly, with the as-yet undisclosed price of the Frontier Pro expected to come in a bit higher than the Z9.

That’s less interesting. What’s more interesting is that the Z9 offers 35 miles (60 km) of range on the base, 17 kWh battery, at a price that significantly undercuts even the Slate EV’s $28,000 pre-$7,500 incentive price tag – and that incentive is far from a sure thing.

What’s more, if you feel like spending a bit more, you can get a Zhengzhou Nissan Z9 equipped with a 32.85 kWh battery that’s good for almost 85 miles (135 km) of all-electric range. And even that extended-range model, at ¥168,900 (about $23,400) is still price-competitive with the Jeff Bezos-backed Slate EV.

In short, it’s bound to be a winner.

It’ll sell, but it won’t sell here

With excitement surrounding the Kia Tasman, Slate, and other, similarly affordable light-duty pickups building on the success of the Ford Maverick hybrid, it should come as no surprise that Nissan has international ambitions for its newest electrified pickup.

“In alignment with our ‘In China, For China, Toward the World’ strategy for electrification and smart transformation, Nissan will fully support ZNA’s ‘off-road strategy,’” explained Stephen Ma, Chairman of Nissan (China) Management Committee and President of Dongfeng Motor Co., Ltd. “We are working to strengthen our research and manufacturing capabilities, further advancing our presence in the core markets of pickups and off-road vehicles, with the ultimate goal of achieving global expansion.”

It’s exciting stuff, but with all the recent troubles it’s been experiencing, it’s doubtful that Nissan will bring either of its new, Chinese-built mid-size pickups to the US (electrified or otherwise).

“The mission of the new generation of Chinese automotive professionals is clear – to ensure that made-in-China cars are driven across the world. ZNA will utilize its dual-brand and dual-channel advantages to expand its global footprint,” Mr. Mao Limin, Executive Vice President of ZNA, at the Z9’s launch. “We aim to be one of the top exporters of pickups within three years and to reach a sales milestone of 100,000 units.”

That said, Nissan Hardbody fans shouldn’t lose hope quite yet. If Nissan is able to find a new savior in Toyota, a Taco-based BEV pickup with a new LEAF/Ariya-type front fascia might make more sense than you think.

Electrek’s Take

I’ve already written out my own comeback plans for Nissan, and this new Chinese truck doesn’t really fit into them. Like many of you, I’m of the belief that a PHEV isn’t an EV – but I do see their value as “lilypad” cars, and the two Lightning owners I know? Their last F-150s were hybrids.

240 ton Hitachi, ABB electric haul truck is revolutionizing Japanese mining

240 ton Hitachi, ABB electric haul truck is revolutionizing Japanese mining

With global demand for battery minerals continuing to rise, tech giants ABB, Hitachi, Komatsu, and Sumitomo are working together, developing a clever tech strategy that’s slashed emissions across Japanese mining operations.

The collaboration between Hitachi Construction Machinery and ABB Traction to build a massive, fully electric 240 ton haul truck for extreme duty mining operations reached a critical stage last year, with the completion of their first prototype in February. Over the last year, Komatsu and Sumitomo have signed on as well, and the new haul trucks are doing their thing at the Kansanshi copper-gold mine in Zambia.

“We are delighted to see our collaboration with Hitachi Construction Machinery reaching this crucial step,” Fabiana Cavalcante, Head of Mobile e-Power, ABB Traction, explained last year. “The project is not only helping to tackle the issues involved in dump truck electrification but is also contributing to enabling a low-carbon world through the reduction of greenhouse gas emissions. We look forward to seeing the prototype prove its capability in the Zambian copper-gold mine.”

The deployment at Kansanshi marks the first OEM-led pilot program of this type of electric vehicle in real-world mining conditions.

And, as for what type of electric vehicle is “this” type of electric vehicle – that was a big topic of conversation at The Electric Mine Conference in Chile last week, where ABB, Hitachi, Komatsu, and Sumitomo discussed not just Hitach’s electrification of FQM’s heavy haul trucks, but also the “trolley-style” overhead charging system that enables the trucks to operate around the clock, without the need to stop for charging.

On level ground, the truck’s electric powertrain draws power from its high-capacity battery. During power-intensive uphill climbs, the truck connects to the overhead wires and draws additional power, minimizing the demands on the battery. On downhill runs, the trucks recharge with regenerative braking.

The mine’s clever three-part system greatly reduces (if not outright eliminates) any downtime associated with charging, and enables the truck to operate almost continuously.

Electrek’s Take


HITACHI CONSTRUCTION MACHINERY COMPLETES PROTOTYPE FULLY ELECTRIC DUMP TRUCK BASED ON ABB’S INNOVATIVE BATTERY TECHNOLOGY

The International Energy Agency (IEA, a Paris-based, 31 nation organization established in 1974 that provides policy recommendations, analysis and data on the global energy sector) projects that mineral demand from EVs will see 30x growth between 2020 and 2040, with demand for lithium and nickel growing 40x as demand for diesel is dropping faster than most people predicted, reaching a 26-year low last summer.

The IEA’s projections take several battery development scenarios into considerationand include increasingly familiar terms like utility-scale battery energy storage. All of which is to say: we’re gonna be mining a whole lot more, for a whole lot longer – and decarbonizing those operations is critical to doing all this properly.

The current plan is to convert Hitachi’s fleet of 2500 HP EH4000 240-ton diesel mining trucks to electric driveYou can learn more about the ABB eMine process in the company’s conceptual (read: it’s all CGI) launch video from last year, below, then let us know what you think of the group’s collaboration in the comments.

Opel Frontera GRAVEL concept previews next Jeep Renegade electric 4x4

Hot on the heels of the Fiat 4×4 Grande Panda Manifesto comes another subcompact Stellantis compact with electric drive and off-road ambitions. Meet the Opel Frontera GRAVEL – which might be our best look yet at the next-generation electric Jeep Renegade coming in 2027.

Based on a lifted Frontera EV and riding on a set of bespoke, 7×16″ Borbet CWE wheels wrapped in aggressive AT tires, Opel says its all-electric Frontera GRAVEL’s emissions-free driving makes it ideally suited for “soft-roading” nature drives (their words, not mine), with a rugged, adventurous 4×4 appearance.

Those rugged, Jeep-like good looks are backed up enhanced by the usual overland accessories, including a front-mounted winch, side storage boxes at the rear, and a lattice-style roof rack. A slew of accessory lights mounted on the Thule Canyon XT carrier and hood, as well, for excellent nighttime visibility off-road and (presumably) retina-searing intensity on-road.

“The new Opel Frontera is already standout,” says Rebecca Reinermann, Vice President of Marketing for Stellantis’ Opel and Vauxhall brands. “It is rugged, practical, and perfect for families and everyday adventures. But with the Frontera GRAVEL show car, we’ve pushed the limits, imagining a tougher, more daring, trailblazing version. This concept is built to fire up our fanbase and test the demand for a bolder, more rugged Frontera in the future. It’s all about freedom, adventure, excitement and pushing boundaries.”

Like the recent Fiat concept mentioned at the top of this post, the production Frontera EV is based on Stellantis’ “Smart Car” BEV-native platform, and features a 113 hp electric motor and more than 300 km of WLTP range (about 185 miles) standard, with the “long range” version able of traveling up to 400 km (about 250 miles) between charges.

Either version comes with the “Pure Panel” digital cockpit featuring dual 10″ displays. For a few dollars quid more, the GS trim adds automatic climate control and Intelli-Seat front seats. And, if Mopar Insider has any idea what’s up, it might actually make for a decent little Jeep Renegade replacement (below).

The Opel Frontera first came to our attention last October, when it became the first new EV from Stellantis to be offered with both ICE and battery power, for the same price – making EV price parity an objectively real thing.

Jeep parent company Stellantis has already confirmed that a new Jeep Renegade that’s priced below the upcoming Jeep Compass EV would be coming to the US as a 2027 model, and it’s expected to share its mechanicals with both the Frontera and Fiat’s recently teased Grande Panda Manifesto. If that does anything for you, let us know in the comments.
