Geothermal startup Fervo Energy announced a key technical milestone on Tuesday, paving the way for geothermal energy to play a bigger role in the transition to clean energy.
Fervo drills deep wells and pumps water into them. The water grows hot from the heat of the earth, then Fervo pumps it back to the surface, where a turbine converts that heat to electricity.
Fervo successfully completed a 30-day test, considered an industry standard for geothermal, at its commercial pilot plant in northern Nevada, the company said in a statement. In the test, Fervo drilled down drilled down to 7,700 feet and then turned to drill another 3,250 feet horizontally, and internal temperatures reached roughly 375 degrees Fahrenheit.
The test at its pilot plant achieved conditions that would generate 3.5 megawatts of electricity production, the company said. A single megawatt is roughly enough electricity to meet the demand of 750 homes at once.
Fervo has just started construction on a 400-megawatt project that it expects to be online by 2028, which would power approximately 300,000 homes.
“Fervo’s successful commercial pilot takes next-generation geothermal technology from the realm of models into the real world and starts us on a path to unlock geothermal’s full potential,” Jesse Jenkins, macro-scale energy systems engineer and professor at Princeton, said in a written statement.
Currently, most geothermal energy resources are located near tectonic plate boundaries where magma gets close to the earth’s surface, heating up water trapped in the earth’s surface nearby. In the United States, geothermal energy supplies only 0.4% of electricity right now.
Instead of relying on naturally occurring conditions, Fervo is using drilling technology developed by the oil and gas industry with hydraulic fracturing to create reservoirs in rocks deep underground.
“By applying drilling technology from the oil and gas industry, we have proven that we can produce 24/7 carbon-free energy resources in new geographies across the world,” Tim Latimer, the CEO of Fervo Energy, said in a written statement.

Leveraging oil and gas drilling technology
A decade ago, Latimer was working in the oil and gas industry as a drilling engineer.
“I loved the work, but I was passionate about climate change. I saw all the tech advancement around me and realized that it could be used for geothermal energy,” Latimer said in a thread he posted on Twitter on Tuesday. Developments in oil and gas drilling, like the development of the polycrystalline diamond cutter, “changed the game,” Latimer said.
“With dramatically lower drilling costs, it would now be possible to drill down to depth and then drill horizontally for enhanced geothermal, significantly increasing the productivity of the resource, and enabling development anywhere,” Latimer wrote on Twitter.
When Latimer first had the idea to use developments in oil and gas drilling to tap into geothermal energy, he faced a lot resistance. The one place he found an interested ear was at Stanford’s geothermal program, where he went to grad school and in 2017 co-wrote and published a paper on the topic. That paper was the foundation for Fervo Energy, which Latimer launched in 2017 with Jack Norbeck, also from Stanford’s geothermal program.
“The last six years have been quite a journey. I never expected how much skepticism and pushback we would receive for what we thought was an obvious idea,” Latimer said in his Twitter thread. “So we set out to systematically prove this was a truly revolutionary, and viable, way of doing geothermal.”
They did find believers, though, and have since raised over $200 million in investment, Latimer said on Twitter.
Fervo’s partnership with Google and looking to the future
Google has been a leader in its commitment to operate on 24-7 carbon-free energy by 2030. “Solving climate change is humanity’s next big moonshot,” Google GEO Sundar Pichai has said.
To deliver on its goal to operate on 24-7 carbon-free energy by 2030, Google has had to buy a lot of renewable energy to support all of its energy-hungry computing processes.
In 2021, Google singed a partnership with Fervo to develop a geothermal power project.
Unlike wind and solar energy, which are intermittent, geothermal energy is an “‘always-on’ carbon-free resource that can reduce our hourly reliance on fossil fuels,” Michael Terrell, Google’s senior director for energy and climate, wrote in 2021 when the partnership was first announced.
“Achieving our goal of operating on 24/7 carbon-free energy will require new sources of firm, clean power to complement variable renewables like wind and solar,” said Terrell in a statement published Tuesday. “We partnered with Fervo in 2021 because we see significant potential for their geothermal technology to unlock a critical source of 24/7 carbon-free energy at scale.”

As part of the partnership, Google is developing the artificial intelligence and machine learning systems to improve Fervo’s efficiency, and Fervo is adding clean energy to the grid in Nevada, where Google is a large clean energy customer.
The U.S. Department of Energy has also launched what it calls the “Enhanced Geothermal Shot,” which is an effort to reduce the cost of enhanced geothermal energy by 90% to to $45 per megawatt hour by 2035. The Department of Energy says it hopes enhanced geothermal systems can potentially provide clean energy to 65 million American homes.
Fervo still has a long road ahead from building a pilot plant to commercializing geothermal energy at scale, but Wilson Ricks, who works in Jenkins’ lab at Princeton and cowrote a paper on the role of geothermal energy in future decarbonized energy systems, says Fervo’s technical milestone is a real milestone.
“This is a very significant milestone in enhanced geothermal systems development. It is the first application of the advanced drilling and well stimulation techniques developed in the shale oil and gas boom to geothermal, and has demonstrated that these can be used to create artificial geothermal reservoirs delivering high flow rates,” Ricks told CNBC. “There is still more development to be done on the path to large-scale and cost-competitive commercial systems, but the significance of this achievement shouldn’t be understated.”
The kind of enhanced geothermal energy systems, like those that Fervo is developing, “could do double-duty as a form of long-duration energy storage, enhancing their ability to complement wind and solar in a decarbonized grid,” Ricks told CNBC.
Members of the US energy industry has committed to investing $100 billion over the next five years to build and buy American-made batteries for large, utility-scale deployments of battery energy storage systems (BESS).
Executives from the American Clean Power Association (ACP) and several utility company representatives said Tuesday that they were committed to a fivefold increase in active investments that could, according to the Association, lead to 100% American-made BESS projects – but that vision depends on both a streamlined permitting environment and predictable tax and trade policy, the ACP said.
This commitments “demonstrate what success can look like,” said ACP CEO Jason Grumet, adding that many industry players have been waiting in a sort of holding pattern until some long-term clarity develops around Trump’s tariff and trade policies. “There is a remarkable tension right now between probably the best fundamentals for investment in the energy sector that we’ve seen in a generation and the greatest amount of uncertainty that we’ve seen in a generation.”
Those fundamentals involve rapidly dropping battery costs with increasing density – and that efficiency improvement is coming with reliability, too, Hyundai joining Tesla (and others) in delivering batteries good for hundreds of thousands of miles of driving. The tension, of course, comes from the fact that most batteries, today, are made in Asia.
Form Energy CEO Mateo Jaramillo says his company sources more than 80% of its battery content in the US and much of the rest from Europe and “non-China Asia.” And, while they’re working to re-shore even more, they remain exposed to heavily tariffed Chinese-made inputs.
Form eventually hopes to source raw iron from US mines in Michigan and Minnesota – and they’re not alone. Executives from other companies spoke up as well:
COVID-era disruptions across the global battery supply chain convinced Fluence that an energy storage market as robust as the United States’ needed a stronger domestic manufacturing base, Fluence Americas President John Zurancik said in the press briefing. The company’s U.S. investments are now bearing fruit as it expects to deliver its first U.S.-made lithium-iron-phosphate, or LFP, batteries this week for deployment later this year, he said.
Like Fluence, LG Energy Solution Vertech expects to significantly expand its U.S. manufacturing operations in 2025 and 2026. The South Korean battery powerhouse will adapt existing production lines at its Holland, Michigan, factory to deliver 16.5 GWh of stationary storage batteries this year and add 11 GWh of new capacity in 2026, its CEO said in a statement provided by ACP.
Even industry stalwarts like Wärtsilä have begun sourcing components for the container-based Quantum 3 BESS system we covered last summer from a geographically diverse set of suppliers, with manufacturing capacity across different regions of North America, Asia, and Europe. This should enable the company’s customers to take advantage of any local tax incentives while avoiding the kind of tariffs impacting global battery markets.
The ACP’s announcement adds about $85 billion to a set of “active investments” worth $10 billion to $15 billion, executives with the trade group said in a press briefing.
Electrek’s Take
Battery energy storage just makes sense – and it’s being leveraged in smart ways by companies like Zenobē, who are using smart BESS deployments to help hold down ratepayer costs while improving grid resilience and reliability. Volvo, too, is working to develop rapidly deployable BESS solutions that can support temporary job sites and disaster relief efforts.
Then there’s the rich people. Located in Abu Dhabi, the world’s largest storage project will feature a 5.2 GW solar PV plant coupled with a 19 gigawatt-hour (GWh) BESS. You can check that out here, then let us know what you think of all these projects in the comments.

Ava Community Energy just rolled out a new program in California that pays EV and plug-in hybrid drivers for charging their cars when electricity on the grid is cleaner and cheaper.
The new Ava SmartHome Charging program, launched in partnership with home energy analytics platform Optiwatt, offers up to $100 in incentives in the first year. And because the program helps shift home charging to lower-cost hours, Ava says drivers could save around $140 a year on their energy bills.
EV and PHEV owners who are Ava customers can download the Optiwatt app for free, connect their vehicle, and let the app handle the rest. The app uses an algorithm to automatically schedule charging when demand is low and more renewable energy is available, typically overnight or during off-peak hours.
“Ava is on a mission to provide 100% clean energy to our customers by 2030,” said CEO Howard Chang. “This new program helps us get there by giving people an easy way to charge on more renewable energy while simultaneously saving money.”
Drivers who enroll get a $75 bonus for joining, and can earn an extra $25 per year if they stay enrolled. Optiwatt shifts charging to off-peak times, and it takes into account the customer’s individual schedules and preferences.
Casey Donahue, who founded Optiwatt, says this program is a win for everyone. “We can move a lot of energy use to cleaner, more affordable times by using smart algorithms and the growing EV base,” he said. “That benefits every Ava customer.”
The program is available to most EVs and plug-in hybrids. All it takes is signing up through the Optiwatt app (iOS, Android, or web) and completing a quick verification process. Savings and rewards start right away.
The Oakland-based not-for-profit public power provider aims to enroll at least 5,000 vehicles by the end of 2025. The company says this program is the first step in a broader virtual power plant (VPP) strategy. It’s powered by Lunar Energy’s Distributed Energy Resource Management System (DERMS) platform, Gridshare, which will help Ava coordinate energy from EVs, home batteries, and more.
Ava Community Energy was founded in 2018 and now serves 2 million people in Alameda County, California, and the cities of Tracy, Stockton, and Lathrop.

Jeep is teasing the new Grand Cherokee, but where’s the EV version of its best-selling SUV?
The Grand Cherokee is due for a refresh, and we just got our first look at it. Jeep claimed “the next chapter in the story of America’s best-selling full-size SUV begins” after releasing the first official images of the updated model. When will we see the Jeep Grand Cherokee as an EV?
2026 Jeep Grand Cherokee first look
Days after revealing the new Compass, Jeep is teasing another refreshed model, its best-selling Grand Cherokee.
Although it was the best-selling full-size SUV in the US last year, the Grand Cherokee is due for an update. The latest model was launched in 2021, but Jeep added a two-row version in 2022.
It remained Jeep’s top seller in the US last year with over 216,000 models sold, but sales were down 12% compared to 2023. It was also one of the best-selling plug-in hybrid (PHEV) vehicles, with over 27,500 4xe models
Jeep is giving us our first official look at the updated 2026 Grand Cherokee, inside and out. The first image previews the front end, which features new LED headlights and a revamped seven-slot grille, similar to the new Compass.
The interior is restyled with a simplified setup and other minor infotainment and climate control display adjustments. The preview also shows an added passenger screen.
When will Jeep launch the Grand Cherokee EV?
Jeep will continue to assemble the updated SUV in Detroit. The new 2026 Jeep Grand Cherokee will be available as a two-row, three-row L, and a plug-in hybrid 4xe, but when will we see an EV version? The outgoing 4xe model is already one of the top three selling PHEVs in the US, so a fully electric version would make sense.
As part of its 2023 agreement with the UAW, Jeep revealed plans to launch the Grand Cherokee EV in 2027. It was scheduled to be built at the Detroit Assembly Complex, but plans have likely changed since then.
Jeep’s new Compass will be available as an EV, but only in Europe. At least for now. Stellantis halted operations at its Brampton Assembly plant earlier this year, where the Compass is built, as it “reassesses its product strategy in North America.”
For those in the US, Jeep currently offers one EV. The Wagoneer S (pictured on the left above), Jeep’s first global electric SUV, starts at $65,200 and has a range of up to 294 miles.
Later this year, Jeep is expected to launch the Recon EV (pictured on the right above), a rugged electric SUV like a Wrangler.
Jeep is currently offering employee pricing plus an extra $1,500 cash allowance on top of the $7,500 EV tax credit on 2025 Wagoneer S models. If you’re looking to snag some savings, you can use our link to find Jeep Wagoneer S models in your area today.
