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

By Robert Buluma Alphaxioms
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 Court Orders New Environmental Review for Imperial County Geothermal Lithium Project

By Robert Buluma Alphaxioms
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...

NYC Subway Thermal Energy Network Pilot: Geothermal Heat Capture, Radiant Cooling, Seasonal Storage

By Robert Buluma Alphaxioms
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...

New Mexico Tribal Geothermal Development: Energy Sovereignty, Jobs, Investment

By Robert Buluma Alphaxioms
New Mexico’s Tribal Lands Poised for Geothermal Development: Opportunity, Challenges, and Pathways to Energy Sovereignty Image:  Located in Lordsburg, Lightning Dock is the only utility scale geothermal power plant in New Mexico. (BLM New Mexico via Flickr) Why geothermal matters for New Mexico tribes, nations, and pueblos Geothermal energy uses heat from the earth to produce electricity or heat buildings directly. For New Mexico — a state with abundant subsurface heat resources — geothermal offers a reliable, low‑emission complement to wind and solar. Unlike intermittent renewables, geothermal provides baseload power capable of supporting grid stability and reducing reliance on fossil fuels. For tribal communities, geothermal has particular appeal: it aligns with many Indigenous values around stewardship, can be developed with relatively low water demand compared with some thermal technologies, and offers long‑term revenue, jobs, and enhanced local control over energy resources.

Dynelectro, Syntholene, and the Geothermal SOEC Breakthrough in Iceland

By Robert Buluma Alphaxioms
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 ...
