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.
Solar panel giant Qcells announced today that it’s temporarily furloughing 1,000 US workers – 25% of its workforce – and reducing pay and shifts at its factories in northeast Georgia due to supply chain delays caused by US Customs.
Qcells furloughs 1,000 workers
The supply chain delays are hindering the company’s ability to import components to build its solar panels. This has resulted in Qcells’ two factories in Cartersville and Dalton being unable to operate at full capacity for several months.
Qcells spokeswoman Marta Stoepker shared the following statement in an exclusive with Channel 2 Action News in Atlanta:
The company says the furloughed workers, who were notified this afternoon, will retain full benefits and won’t be laid off. However, Qcells will no longer be using staffing agency employees in Georgia “at this time.”
As Qcells introduced new supply chains to support its growing solar panel manufacturing facilities in Georgia, the company was recently forced to scale back production while our shipments into the US were delayed in the customs clearance process.
Although our supply chain operations are beginning to normalize, today we shared with our employees that HR actions must be taken to improve operational efficiency until production capacity returns to normal levels.
Stoepker said it expects to bring the furloughed workers back “in the coming weeks and months.” She continued:
Our commitment to building the entire solar supply chain in the United States remains. We will soon be back on track with the full force of our Georgia team delivering American-made energy to communities around the country.
Electrek’s Take
In January 2023, the Seoul-headquartered Qcells announced it would invest more than $2.5 billion to build a solar supply chain in Georgia – the largest-ever investment in clean energy manufacturing in the US to date. That included expanding the Dalton solar factory and building a fully integrated solar supply chain factory in Cartersville, Georgia, that will manufacture solar ingots, wafers, cells, and finished panels.
It’s not quite there yet, because that takes time. In the meantime, it’s being penalized by Customs. The US government under Trump says it’s keen on boosting domestic manufacturing. Why would it work against a company that’s onshoring an entire solar supply chain, including recycling?
Dalton and Cartersville employ nearly 4,000 people. Its total output will reach 8.4 GW of solar production capacity per year, which is equivalent to nearly 46,000 panels per day – enough to power approximately 1.3 million homes annually.
It’s ludicrous that it has been forced to furlough a quarter of its workforce due to the ineptness of the Trump administration’s US Customs policies. This is right up there with the ICE arrests at Hyundai’s plant in Georgia. Bravo.

The breakthrough EV batteries Toyota says will double driving range and cut charging times are facing another setback. The company is once again delaying plans for a new battery plant in Japan.
Why is Toyota delaying its EV battery plant this time?
Earlier this year, Toyota bought a 280,000-square-meter plot of land in Fukuoka, Japan, where it planned to build a plant to produce the more advanced EV batteries.
A location agreement was expected to be signed by April, but Toyota pushed back construction by several months, blaming slower-than-expected demand for electric vehicles.
The agreement was expected to be finalized this Fall, but that will no longer be the case. According to Nikkei, Toyota is delaying the EV battery plant for the second time. Toyota will review and adjust plans over the next year.
Fukuoka governor, Seitaro Hattori, confirmed the news with reporters on Friday following a meeting with Toyota’s president, Koji Sato. Hattori also shut down claims that Toyota was planning to scrap the battery plant altogether.
Toyota again blamed slowing EV demand for the delay. The decision comes despite Keiji Kaita, president of Toyota’s Carbon Neutral Advanced Engineering Development Center, confirming at the Japan Mobility Show just last week that it’s “sticking on the schedule” to introduce its first solid-state battery-powered EV by 2028.
Last month, Toyota said it aimed to “achieve the world’s first practical use of all-solid-state batteries in BEVs” after securing a partnership with Sumitomo Metal Mining Co. to mass-produce them. It’s also working with Japanese oil giant Idemitsu.
The company recently revealed a solid-state battery pack prototype that it claims can deliver 747 miles (1,200 km) range and 10-minute fast charging, but will we ever see it actually in production?
Electrek’s Take
Toyota has been making empty promises about EV batteries for almost a decade now. It initially planned to introduce solid-state EV batteries in 2020, then pushed it to 2023, then 2026, and now it’s saying it will be around 2028.
Mass production is likely closer to the end of the decade, if Toyota doesn’t delay it again. While it’s blaming the slowing demand, global EV sales are still on the rise. According to Rho Motion, global EV sales topped 2 million for the first time in a single month in September 2025. Through the first nine months of the year, EV sales are up 26% compared to the same period in 2024.
Even with the US ending the $7,500 federal tax credit and other policies designed to promote electric vehicles, global adoption will continue building momentum over the next few years.
Is it a demand issue, or is Toyota just looking for another excuse? With rivals like Volkswagen, Mercedes-Benz, Hyundai, BMW, and Honda advancing next-gen EV batteries, Toyota will only fall further behind if it continues delaying key projects.
