Croatia Signs Grant Agreement to Drill Four Geothermal Wells for Urban Heating Croatia has approved a major new investment to expand the use of geothermal energy for district heating in four cities. Velika Gorica, Osijek, Vinkovci, and ZapreÅ¡ić are set to receive an additional EUR 35.3 million for geothermal development, including the drilling of four new wells that could support urban heating systems by 2030. The funding marks the second phase of a broader geothermal program designed to convert Croatia’s underground heat resources into reliable, domestic energy for homes, public buildings, businesses, agriculture, and industry. Across the two phases, the total investment in the four locations is expected to reach approximately EUR 86 million. The project is significant because it moves Croatia’s geothermal strategy beyond exploration. The country is now preparing the infrastructure needed to create production-and-injection well pairs, establish closed geothermal systems, an...
Ruhr’s Geothermal Opening By: Robert Buluma Germany’s largest geothermal exploration permit has been granted to a consortium planning to investigate the Ruhr region from Oberhausen to Hamm, and the significance goes far beyond a routine licensing milestone. The permit covers 1,640 square kilometers, making it the biggest geothermal exploration field in Germany to date, and it positions the Ruhr as a serious test case for urban geothermal heat at scale . This is a story about more than geology. It is about how a heavily industrialized region, with dense heat demand and established district-heating infrastructure, may be able to turn a deep subsurface resource into a practical climate strategy. If the exploration work succeeds, the project could reshape how Germany approaches low-carbon heating in cities and industrial corridors . 1 . The opening move The permit granted by the Arnsberg District Government opens the door for an extensive exploration phase under the banner “Erdwärme M...
