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 ...
Archi and Ormat Join Forces to Unlock North Sulawesi's Geothermal Potential In an exciting venture that marks a new chapter in Indonesia’s renewable energy landscape, PT Archi Indonesia and Ormat Technologies Inc. have established a joint venture, PT Toka Tindung Geothermal (TTG). This partnership aims to explore and harness geothermal energy in the Bitung area of North Sulawesi, leveraging the geothermal potential around Archi’s Toka Tindung gold mine. Ormat, a global leader in geothermal energy development, holds a 75% stake in the joint venture, while Archi, a pure-play gold mining company, owns the remaining 25%. This collaboration exemplifies how industries traditionally associated with mining and fossil fuels are now shifting towards sustainable energy practices. As part of the agreement, Ormat will spearhead exploration activities, focusing on the Klabat Wineru geothermal prospect. Once the geothermal potential is confirmed, Ormat will also oversee the design, engineering, a...
