Turning Deep Earth Heat Into a Scalable Climate Solution: Green Therma and GFZ Potsdam Launch Breakthrough Geothermal Demonstration By: Robert Buluma Published on January 17, 2026 In the quest for reliable, carbon-neutral energy, geothermal heat stands out as one of the most promising yet underutilized resources. Unlike solar or wind, which depend on weather, geothermal energy draws from the Earth's constant internal heat — a source that's available 24/7, year-round. However, traditional geothermal systems often face high costs, geological risks, and significant heat loss when extracting energy from great depths. Enter Green Therma, a Danish innovator, and the Helmholtz Centre Potsdam GFZ (Germany's leading earth sciences research center). In early 2026, they're launching a groundbreaking demonstration at the renowned geothermal research site in Groß Schönebeck, north of Berlin. This project marks the world's first real-world installation of Green Therma's pate...
