Templin Lies on a Hot River: How Geothermal Energy Could Secure Affordable District Heating By:  Robert Buluma  A Hidden Treasure Beneath the Uckermark For more than 25 years, the NaturTherme Templin has been pumping thermal brine from a depth of 1,650 meters, using it as a healing remedy. The water that rises from this depth has a temperature of 57.7 degrees Celsius—impressive by any measure, but only a fraction of what lies beneath. During a routine annual check-up of the production well, geothermal specialists from Neubrandenburg posed a question that would set in motion one of the most ambitious energy projects in the region: Did the city even know what treasure it was sitting on? The answer, it turned out, was no. And that realization has since transformed Templin into a pioneer in Germany's heating transition. The Assessment That Changed Everything The city was already working on a heating concept aimed at achieving a sustainable, fossil-fuel-independent supply. The Natu...

Pioneering Industrial Deep Geothermal in Île-de-France: Safran Aircraft Engines and Dalkia Achieve Major Milestone at Villaroche Site By: Robert Buluma In a major step forward for industrial decarbonization in France, Safran Aircraft Engines — a global leader in aeronautical propulsion — has partnered with Dalkia (an EDF subsidiary) to develop the first deep geothermal station dedicated to industry in the Île-de-France region. Announced in a press release on February 18, 2026, the project at Safran's Villaroche industrial site in Seine-et-Marne has reached a key milestone: the producer well (puits producteur) has been successfully drilled to a depth of 1,650 meters, tapping into naturally heated water at around 75°C. Drilling for the injector well is now underway, with completion expected in April 2026 and full commissioning of the geothermal plant targeted for autumn 2026. This innovative installation combines deep geothermal energy, high-efficiency heat pumps, and modernized ...

Geothermal Energy Permits in Denmark: Mapping the Country’s Quiet Heat Revolution (December 2025) By: Robert Buluma Denmark is globally admired for its wind power leadership, ambitious climate policies, and strong district heating systems. Yet beneath its flat landscapes lies another energy resource that is steadily gaining strategic importance: geothermal energy. As of December 2025, Denmark’s geothermal sector is entering a new phase marked by fresh permit applications, and even approval  expanding geographic interest, and stronger alignment with the country’s long-term decarbonization goals. An overview of current geothermal permits and applications reveals not only where development is happening, but also how geothermal energy is quietly positioning itself as a cornerstone of Denmark’s renewable heat future. Geothermal Energy and Denmark’s Heat Transition More than 60 percent of Danish households are connected to district heating networks, making heat decarbonization a national...
