"US Geothermal Tax Credits 2026: What the IRA/45Q Changes Mean for Developers"

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...

Arverne’s New Geothermal Drill Could Unlock a Billion-Dollar Lithium Treasure

Arverne Launches First Geothermal Drilling for the Lithium de France Project in Alsace


Published: November 24, 2025
Location: Pau, France

In a milestone moment for Europe’s geothermal and critical-minerals sectors, Arverne (ARVEN) — France’s leading geothermal solutions provider — has officially begun drilling the first geothermal doublet for the groundbreaking Lithium de France project in Schwabwiller, Alsace. This launch marks a major step toward establishing Europe’s first integrated geothermal-lithium production ecosystem.

A New Chapter for European Geothermal Innovation

According to the company, drilling operations have begun precisely on schedule following extensive site preparation. The geothermal doublet, which includes a production well and a reinjection well, will start at 10 meters apart on the surface and expand to nearly 1 kilometer of horizontal separation at a depth of 2,400 meters.

This phase is crucial. The initial drilling campaign will verify three essential parameters of the geothermal reservoir:

Flow rate

Temperature

Lithium content


These measurements will feed into advanced geological models and help optimize the project’s technical design ahead of full-scale development.

Geothermal Heat + Sustainable Lithium: A First for France

The Lithium de France project is more than a geothermal installation — it is a flagship initiative combining carbon-free geothermal heating with low-carbon lithium extraction.

Key benefits for the region include:

✔ Carbon-free heat for northern Alsace, delivered through short, local energy circuits
✔ Production of low-carbon lithium for Europe’s growing electric-mobility market
✔ Up to 200 new direct jobs generated locally
✔ Up to 90% lower CO₂ emissions compared to natural-gas heating
✔ About 70% less CO₂ emissions than conventional lithium sources, according to the company’s PFS and EcoInvent data

This dual-production model positions France as a leader in sustainable mineral extraction and strengthens Europe’s push for energy sovereignty.

A Seven-Month Drilling Campaign with Major Economic Impact

Drilling of the first doublet will continue for approximately seven months, contributing to Arverne’s projected business growth in 2025–2026. The company reaffirmed its 2025 guidance, expecting a gross activity volume between €25 million and €27 million, representing a significant +45% to +55% increase over 2024.

A Vision of European Energy Sovereignty

Arverne CEO and founder Pierre Brossollet celebrated the achievement, calling it the result of five years of intense effort:

“By combining geothermal heat and sustainable lithium extraction in Europe, this project embodies a new era of energy sovereignty and reindustrialization for our country. This milestone brings us closer to the final investment decision — a key step toward realizing our ambitions.”

Green Therma Selects H&P to Drill Denmark’s Longest Geothermal Well

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 ...

Dynelectro, Syntholene, and the Geothermal SOEC Breakthrough in Iceland

Dynelectro, Syntholene, and the Geothermal SOEC Breakthrough in Iceland Dynelectro’s role in the Syntholene Iceland project highlights a major shift in how the market should think about SOEC technology. For years, solid oxide electrolysis cells have been seen as highly efficient but too difficult to commercialize because of stack degradation, short operating life, and the complexity of integrating them into real industrial systems. This project helps challenge that view by showing how geothermal integration, advanced power electronics, and system-level design can make SOEC a credible industrial solution.   The most important takeaway is simple: the market has often misunderstood SOEC as a technology limited by chemistry alone, when in fact a large part of the challenge is operational. Dynelectro’s approach shows that if the stack is controlled properly and supported by the right electrical architecture, SOEC can move much closer to commercial viability. The Syntholene Iceland ...
