Global Geothermal Power Market Review 2026.

By Robert Buluma Alphaxioms
Global Geothermal Power: Policies, Funding, Wells, Strengths, Opportunities and Barriers Geothermal is moving into a broader investment cycle. In 2026, the story is no longer limited to volcanic power plants in a few classic markets; it now includes enhanced geothermal systems, closed-loop designs, district heating, superhot rock, lithium from brines and industrial heat. Across the United States, Canada, Germany, the United Kingdom, Australia, New Zealand, Japan, Iceland, France and Italy, the sector is being shaped by a simple question: who is de-risking the first wells, and who is ready to finance the next ones?  United States: the next-generation testbed The United States has the broadest geothermal innovation ecosystem in this group, with a mature conventional base in the West and a fast-growing next-generation pipeline. The main policy signal in 2026 is the Department of Energy’s US$171.5 million funding opportunity for next-generation geothermal field-scale tests, exploration...

Top 10 Critical Geothermal Energy Problems Costs Risks Seismicity

By Robert Buluma Alphaxioms
Top 10 Geothermal Problems: Why a 24/7 Resource Still Struggles to Scale Image credit : Fida, C.E.O Geosilica... This is what scaling looks like downhole in geothermal pipes Intelligence; Strategy for the Geothermal Decade Geothermal energy is often presented as the clean firm resource that can support a renewable electricity system around the clock. It does not depend on sunshine, it can operate through calm weather, and it can provide heat and power for decades. Kenya already relies heavily on geothermal generation , Iceland uses geothermal heat across its economy, and next generation developers are now signing large power contracts with technology companies seeking reliable carbon free electricity. Yet the global geothermal sector remains small compared with solar and wind, with installed electricity capacity still near 16 GW.  That gap is not caused by one obstacle. It is produced by a chain of interlocking problems involving geology, drilling, finance, permitting, public acce...

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

By Robert Buluma Alphaxioms
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...

EIG Geothermal Catalyst Partners Launches Inaugural Power Planet Investment

By Robert Buluma Alphaxioms
EIG’s First Geothermal Bet Signals a New Phase for EGS Financing Image : Thematic image of a geothermal plant EIG Geothermal Catalyst Partners’ inaugural investment in Power Planet is a meaningful signal for the geothermal sector because it links development capital with a project that already has infrastructure, interconnection capacity, and subsurface data on its side . For an industry that often struggles to move from concept to bankable execution, that combination can shorten timelines and reduce risk. Why This Deal Matters The core story is not just that EIG made its first investment; it is that the fund is targeting the middle of the geothermal value chain, where projects need capital to clear technical and commercial hurdles . That matters because enhanced geothermal system, or EGS, projects can be highly promising but capital-intensive, especially before they reach a stage where traditional infrastructure investors feel comfortable stepping in . Power Planet’s Star Peak proje...

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 ...
