Exergy Gemini Turbine vs Ormat Ormega100: Two Different Paths to Geothermal Scale image : a thematic view of a geothermal turbine "blade" Geothermal power is entering a new phase. Two of the most important announcements in the sector point to larger, more standardized, and more commercially viable binary geothermal systems: Exergy’s Gemini Turbine and Ormat’s Ormega100 . At first glance, both machines promise major gains in scale, but they are not trying to solve the same problem in exactly the same way. Gemini is built around a high-capacity radial outflow turbine architecture that can deliver up to 60 MWe per shaft, while Ormega100 is designed as a 100 MW binary surface power unit intended to accelerate enhanced geothermal system commercialization. For project developers, utilities, and data-center buyers looking for firm clean power, the comparison matters because it reveals two competing ideas about how geothermal should grow. Exergy is emphasizing turbine architectur...

Best US States for Geothermal Investment The best US states for geothermal investment are California, Nevada, Utah, New Mexico, and Texas, with Oregon, Idaho, Alaska, and Arizona also offering attractive upside depending on whether you want operating assets, early-stage development, or next-generation geothermal exposure. Geothermal is becoming a broader investment story than it was a few years ago. Stronger drilling methods, rising demand for firm clean power, and more state-level policy support are widening the field beyond the traditional western hot spots. Introduction For investors , geothermal is one of the few clean energy technologies that can deliver round-the-clock power with a relatively small land footprint. That reliability is a big advantage in a market where utilities, data centers, and industrial customers increasingly want clean electricity that behaves more like conventional baseload generation. The challenge is that geothermal is highly location-dependent. The qualit...

Enhanced Geothermal Systems (EGS) Market Size and Investment Outlook to 2034 Enhanced Geothermal Systems are at an inflection point. For years, EGS sat in the “promising but pre‑commercial” category of clean technologies, constrained by drilling cost, subsurface risk, and limited policy attention. That picture is now changing as next‑generation geothermal developers raise larger rounds, sign serious offtake agreements, and move projects from concept to execution.   At the same time, global demand for firm, low‑carbon power is rising faster than conventional geothermal can supply. Thermal plants are retiring, grids need 24/7 clean electricity, and policymakers are discovering that weather‑dependent renewables cannot carry the entire load alone. EGS is emerging as one of the few technologies capable of delivering baseload clean power using a resource available almost everywhere: deep, hot rock. Current EGS Market Size – Small but Strategic In absolute terms, the EGS market is s...

GA Drilling : Deep Drilling Technology, Financing, and Geothermal Scale-Up Image: A GA Drilling Bit GA Drilling is one of the more important technology companies in the geothermal sector because it is trying to solve a problem that has limited geothermal growth for decades: the cost, complexity, and risk of drilling deep wells in hard rock. Rather than operating a geothermal power plant itself, the company focuses on the drilling side of the value chain, developing technologies that can make deep geothermal wells faster, cheaper, and more reliable to build. That positioning gives it a different role from most geothermal developers, and it also makes it strategically significant for the future of clean baseload energy. The geothermal industry has always been constrained by subsurface uncertainty. Developers know where the heat is in a general sense, but they still must drill through high-temperature, abrasive, fractured, and often unpredictable rock to get there. In many projects, dril...

Geothermal Engineering Limited (GEL) : Technology, Financing, and Progress Image : Ryan Law is the C.E.O at GEL Geothermal Engineering Limited (GEL) is one of the UK’s most important geothermal developers, with a flagship deep-geothermal project at United Downs in Cornwall and a growing strategy that combines electricity, heat, and lithium extraction. It has also attracted a mix of private capital, public grants, and bank financing to move from exploration and drilling into commercial operations. Company overview GEL was incorporated in 2008 and is registered in Cornwall as a private limited company focused on electricity production, utility construction, and test drilling and boring. Its core mission is to use geothermal resources beneath the ground to support low-carbon power, heating, cooling, and ultra-low-carbon lithium production in the UK. The company presents itself as a lean specialist team built around geothermal engineering, geology, and community engagement capabilities. ...
