Green Therma Selects H&P to Drill Denmark’s Longest Geothermal Well for Aalborg Heat4Ever Demonstration Denmark is moving from geothermal ambition to execution. Green Therma has selected Helmerich & Payne to drill the Heat4Ever demonstration well near Aalborg, a project that could become one of the country’s most technically ambitious geothermal developments and a meaningful test of closed-loop district heating. A milestone for Danish geothermal The Aalborg Heat4Ever project matters because it is designed to prove that geothermal heat can be delivered without relying on a natural hot-water reservoir. Instead of producing groundwater from a conventional geothermal field, the system uses a closed-loop pipe-in-pipe design that circulates the same fluid downhole, heats it in contact with hot rock, and returns it to the surface for district heating use. That distinction is important for Denmark, where district heating is already a major part of the energy system ...
California Appeals Court Orders New Environmental Review for Imperial County Geothermal–Lithium Project Image: California Salton Lake Sea Hell’s Kitchen geothermal and lithium extraction plan sent back for deeper water, air-quality and mitigation analysis under CEQA A California appeals court has ordered Imperial County to conduct a more rigorous environmental review of the proposed Hell’s Kitchen geothermal power plant and lithium extraction project near the Salton Sea. The Fourth District Court of Appeal found that the county’s original environmental impact report (EIR) did not adequately address long-term water availability, enforceable mitigation measures for water shortages, or potential air-quality impacts tied to the receding Salton Sea. The ruling partially reverses a lower court decision and remands the case to Imperial County Superior Court, requiring the county and project developer Controlled Thermal Resources to address the identified deficiencies before the project can m...
