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 ...
Germany Supercharges Geothermal Energy for a Carbon-Free Future
Germany has just lit a fire under its clean energy transition only this time, the heat is coming from deep underground.
By: Robert Buluma
On August 6, 2025, the government approved a bold bill to fast-track geothermal projects across the country. The move could transform how millions of homes and businesses are heated, slashing carbon emissions and cutting dependence on fossil fuels.
What’s Changing
- Faster Approvals: No more endless waiting—geothermal plants, district heating lines, heat pumps, and thermal storage will get priority treatment.
- Overriding Public Interest: Geothermal now ranks alongside wind and solar, unlocking faster permits and smoother planning.
- Looser Exploration Rules: Drilling and subsurface studies will face fewer restrictions.
Why It Matters
Geothermal could supply over a quarter of Germany’s heating needs—and it’s available 24/7, rain or shine. With 42 plants already running and 16 more under construction, the sector is ready to surge.
The Big Picture
This is part of Germany’s larger push to phase out fossil heating by 2045. It’s also a direct response to the energy shocks of recent years, proving the country is serious about secure, clean, homegrown heat.
Bottom line: Germany is digging deepliterallyfor its climate future. If lawmakers pass this bill, expect a geothermal boom that could set a global example for sustainable heating.
