Who Is Really Funding Next-Gen Geothermal in 2026? Next-generation geothermal has moved beyond laboratory research into a capital-intensive commercialization phase. In 2026, the most important financing is no longer coming from one investor category: venture capital funds are financing drilling, subsurface modelling and hardware; strategic energy companies are providing equipment, project access and market credibility; banks are beginning to lend against contracted projects; and governments are absorbing exploration and first-of-a-kind technology risk. The strongest financing activity is concentrated in the United States and Canada, but Europe is becoming increasingly important through Germany-based deployment, European Union grants, UK innovation support, and strategic participation from European energy companies. The central investment question is changing from “Can this technology work?” to “Can the developer deliver repeatable, financeable projects at commercial cost?” The 2026 fun...
Green Therma and the Future of Geothermal Scale in Europe By: Robert Buluma Geothermal energy has long been one of the most intriguing renewable resources in the global clean energy mix. It is steady, local, and available around the clock, unlike solar and wind, which depend on weather and daylight. Yet despite these advantages, geothermal has often remained a niche part of the energy landscape. The reason is not a lack of potential, but a combination of technical complexity, high upfront drilling costs, site-specific geology, and the challenge of scaling projects in a repeatable way. That is why companies promising a new generation of geothermal systems tend to attract attention. Green Therma is one of those companies. Its message is bold: geothermal technology for scale, potentially up to 25,000 wells in Europe. That is a major claim, and it deserves careful attention. If such a model works, it could change how Europe thinks about district heating, industrial heat, and energy securi...
