Green Therma and Stadtwerke Wismar Sign Letter of Intent to Explore Geothermal District Heating in Germany Wismar, Germany – May 12, 2026 — A new step toward decarbonizing urban heating systems has been set in motion after Green Therma ApS and Stadtwerke Wismar GmbH signed a Letter of Intent to jointly assess the potential for deploying geothermal district heating in Wismar, Germany. The agreement marks an early but strategic move toward integrating advanced closed-loop geothermal technology into one of northern Germany’s established district heating networks, as cities across Europe accelerate efforts to phase out fossil-fuel-based heating systems. Early-Stage Collaboration Targets Clean Heat Transition Under the agreement, both organizations will work together to evaluate whether geothermal energy can be integrated into Wismar’s existing district heating infrastructure. The partnership will begin with a structured pre-feasibility study covering geological screening, technical e...
In a bold step toward redefining the future of clean energy, Orkuveitan, Iceland’s leading utility company, has announced its next major geothermal milestone — the IDDP-3 superhot drilling project. By: Robert Buluma Presented by Hera Grímsdóttir, Executive Director of Research and Innovation at Orkuveitan, during the Superhot Summit in Reykjavík’s Harpa Conference Center, this initiative marks the dawn of a new era in geothermal energy utilization. The event, organized by Iceland’s Minister of Environment, Energy, and Climate Jóhann Páll Jóhannsson in collaboration with the national energy sector, showcased Iceland’s ambition to fast-track the development of next-generation geothermal systems. A joint declaration of intent was signed between the Ministry and three major energy companies — Landsvirkjun, Orkuveitan, and HS Orka — solidifying their cooperation on the Iceland Deep Drilling Project (IDDP-3). The Next Frontier: Deep Drilling into the Earth’s Core In her keynote, Hera Grímsdó...
