Global Geothermal Policy Outlook for 2027 Across Key Markets

Global Geothermal and Energy Policies for 2027: A Future Outlook Introduction The next phase of global geothermal development will be shaped not only by geology and technology, but increasingly by national energy policy . Governments are now treating geothermal as more than a niche source of heat or power . They are beginning to see it as a practical option for firm low-carbon electricity, district heating, industrial heat, and energy security. That shift matters because geothermal projects are unusually sensitive to policy design. Exploration is capital intensive, drilling is expensive, subsurface risk is real, and project timelines can stretch over years before revenue begins. In other words, geothermal is not just an engineering challenge. It is also a finance, regulation, and infrastructure challenge. Looking toward 2027, five countries offer a useful benchmark for where geothermal policy may be heading: the United States, the United Kingdom, Norway, Canada, and France. Each countr...

Geothermal Funding, August ,September 2027 With Intelligence into 2028

Geothermal Funding in August and September 2027: Investment Outlook and Intelligence Into 2028 Geothermal funding in August and September 2027 is likely to focus on projects that can demonstrate commercial resource potential, credible drilling plans, secure offtake, and a clear path to construction. The market will increasingly move beyond broad technology experimentation toward financeable geothermal assets supported by government grants, development-finance institutions, strategic investors, utilities, and corporate power buyers. The most significant investment themes will likely include enhanced geothermal systems , exploration drilling, closed-loop geothermal , data-center power supply, conventional geothermal expansion in East Africa, and blended finance for emerging markets. By 2028, investors are expected to distinguish more sharply between companies with proven technical performance and those still dependent on laboratory results or unconfirmed resource estimates. The 2027 Fun...

"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...

Quaise Energy’s Project Obsidian in Oregon: The World’s First Commercial Superhot Geothermal Plant

The New Energy Frontier: Quaise Energy’s Superhot Geothermal Gambit in Oregon By Alphaxioms Editorial Team | September 4, 2026 In the high desert of Central Oregon, a project with implications far beyond Deschutes County is taking shape. Quaise Energy, now backed by a total of $280 million in funding, is advancing Project Obsidian, which it describes as the world’s first commercial superhot geothermal power plant . The company says the first phase is designed to deliver 50 MW by 2030, with a pathway toward 250 MW and ultimately more than 1 GW . Before the first megawatt reaches the grid, however, the project faces a local policy test: whether Deschutes County should grant a five-year property tax abatement under Oregon’s Rural Renewable Energy Development Zone Program. That decision is more than a routine incentive request. It is a referendum on how rural counties choose to support next-generation energy infrastructure and whether older incentive frameworks can accommodate a technolog...
