The Geothermal “Holy Grail” Just Got a Reality Check: Inside Eavor’s Geretsried Breakthrough May 22, 2026 It’s not every day a deep-tech energy company publishes a detailed technical report that openly documents what went wrong on its flagship project—and still comes out looking stronger. That’s exactly what Eavor Technologies did with its Geretsried geothermal project in Bavaria, Germany. The result is unusually transparent: part technical post-mortem, part validation of a technology many have doubted for years. And the core message is simple. They built it. It works. But it wasn’t smooth. The short version Eavor is trying to solve one of geothermal energy’s hardest problems: how to produce reliable heat and power anywhere, not just in rare volcanic hotspots. Their claim has always been bold: a closed-loop geothermal system that is scalable, dispatchable, low-carbon, and independent of natural reservoirs. Critics have long argued it wouldn’t survive real-world conditions—e...
The global energy sector is undergoing a radical transformation, with clean, reliable, and sustainable power sources taking center stage. By: Robert Buluma Among these, geothermal energy stands out as an underutilized but highly promising resource that offers baseload power generation with near-zero carbon emissions. The rise of advanced geothermal technologies has attracted significant investments, especially from big tech companies seeking sustainable energy solutions for their energy-intensive AI data centers. One such company making headlines is XGS Energy, a geothermal startup that recently closed a $13 million equity bridge round and is preparing for a $60 million to $100 million growth round. This article explores how XGS Energy and other enhanced geothermal system (EGS) startups are revolutionizing the sector, unlocking geothermal energy potential beyond traditional hotspots, and why investors and technology giants are betting big on this clean energy rev...
