US Geothermal Tax Credits in 2026: What Is Actually Still Alive After OBBBA For an industry that spent more than a decade building financial models around a stable federal incentive structure, 2026 has been a year of whiplash. The 30% federal geothermal tax credit that developers and homeowners built forecasts around is gone in one form and still alive in another, and even the IRS’s own public guidance has been confusing enough to trigger uncertainty across the market. That confusion is not a minor clerical issue. It is shaping investment decisions, contractor sales pitches, homeowner timelines, and project finance assumptions right now. If you work in geothermal, the key question is no longer whether federal incentives exist, but which incentive applies, to which project type, and under what ownership structure. The law that changed the timeline To understand where things stand in 2026, you have to start with the Inflation Reduction Act of 2022, which created a long runway for clean e...

Utah FORGE Begins Extended Circulation Utah FORGE has launched an extended circulation test at its Milford, Utah field site, marking a major step forward in the development of enhanced geothermal systems. The new phase is designed to examine how the reservoir behaves during continuous operation and to generate the long-term performance data needed to evaluate commercial viability. For a project focused on de-risking geothermal technology, this is one of the most important milestones yet. Introduction Utah FORGE, the world’s only full-scale field laboratory dedicated to testing and improving the technologies required for enhanced geothermal systems , has entered a new extended circulation phase at its site approximately 10 miles northeast of Milford, Utah. The test is expected to run for roughly four months, with the possibility of extending to 120 days depending on operational conditions. This stage matters because geothermal development is not only about finding heat underground; it i...

DOE’s $10.75 Million University Push Could Reshape the Geothermal Talent Pipeline Image: Thematic image of a geothermal power plant   The U.S. Department of Energy’s Hydrocarbons and Geothermal Energy Office has announced up to $10.75 million for U.S. colleges and universities to support early-stage research and training in subsurface energy development. The program sits inside the University Training and Research framework, and it is designed to strengthen the next generation of energy professionals while advancing research relevant to geothermal, oil and gas, and coal-related subsurface challenges . This announcement matters because it goes beyond a simple grant call. It connects university research, student training, and industry relevance in one funding structure, which is exactly the kind of model geothermal advocates have long argued is needed to accelerate deployment. For the U.S. geothermal sector, the message is clear: talent development is now part of energy infrastruct...

Green Therma Selects H&P to Drill Denmark’s Longest Geothermal Well for Aalborg Heat4Ever Demonstration Denmark is moving from geothermal ambition to execution. Green Therma has selected Helmerich & Payne to drill the Heat4Ever demonstration well near Aalborg, a project that could become one of the country’s most technically ambitious geothermal developments and a meaningful test of closed-loop district heating.   A milestone for Danish geothermal The Aalborg Heat4Ever project matters because it is designed to prove that geothermal heat can be delivered without relying on a natural hot-water reservoir. Instead of producing groundwater from a conventional geothermal field, the system uses a closed-loop pipe-in-pipe design that circulates the same fluid downhole, heats it in contact with hot rock, and returns it to the surface for district heating use.  That distinction is important for Denmark, where district heating is already a major part of the energy system ...

California Appeals Court Orders New Environmental Review for Imperial County Geothermal–Lithium Project Image: California Salton Lake Sea Hell’s Kitchen geothermal and lithium extraction plan sent back for deeper water, air-quality and mitigation analysis under CEQA A California appeals court has ordered Imperial County to conduct a more rigorous environmental review of the proposed Hell’s Kitchen geothermal power plant and lithium extraction project near the Salton Sea. The Fourth District Court of Appeal found that the county’s original environmental impact report (EIR) did not adequately address long-term water availability, enforceable mitigation measures for water shortages, or potential air-quality impacts tied to the receding Salton Sea. The ruling partially reverses a lower court decision and remands the case to Imperial County Superior Court, requiring the county and project developer Controlled Thermal Resources to address the identified deficiencies before the project can m...

New York’s Subway Heat Turned into Winter Warmth: The City’s First Transit Thermal Energy Network Pilot Turning platform heat into usable energy — what the Chambers Street and Brooklyn Bridge–City Hall pilot means for urban energy systems New York City has launched a study to design and test a Thermal Energy Network (TEN) that would capture excess heat from two of Lower Manhattan’s hottest subway stations and reuse it to heat nearby municipal buildings. The proposed pilot, centered on the Brooklyn Bridge–City Hall 4/5/6 complex and the Chambers Street J/Z station, is notable for being the first time TENs are being considered inside a U.S. transit system. The plan pairs radiant cooling on platforms with geothermal borehole storage under an abandoned center platform at Chambers Street, converting otherwise wasted heat into a supply that can be stored seasonally and delivered to surrounding municipal facilities during colder months. This initiative sits at the intersection of urban heat r...
