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 ...

Units 1 and 2 of the Loviisa plant (Image: Fortum)
The Loviisa power plant, boasting two state-of-the-art VVER-440 type pressurized water reactors, was the inaugural nuclear power facility in Finland and continues to furnish over 10% of the nation's electricity. Unit 1 of Loviisa commenced commercial operations in 1977, with unit 2 following suit in 1981. These units' operating licenses were renewed in 1998 and 2007 respectively. Fortum, the company operating the facility, submitted an application to TEM in March 2022 to extend the operating licenses of both units until 2050.
The Finnish government is currently assessing Fortum's application, soliciting statements from various authorities, organizations, and municipalities in the affected region and providing citizens with an opportunity to voice their opinions. The government will make its decision on the operating license based on these statements.
STUK, the regulatory body overseeing the facility, stated that Fortum has "demonstrated that it is able to continue operating both units of the Loviisa nuclear power plant safely even after the expiry of the current license period." The regulator added that the company has the "required capabilities, procedures, competence, and resources to continue safe operations and aging management." STUK also stated that Fortum has "demonstrated in its application and in its safety assessment that it is possible to continue the final disposal safely within the current scope."
Sasu Valkamo, Vice President of the Loviisa plant, remarked that "as a result of the Loviisa power plant's continuous improvement of safety and aging management, the power plant is in good condition and the lifetime extension is possible." Fortum has implemented several modernizations and renovations throughout the facility's history. The company also highlighted that STUK continuously monitors the implementation of its safety improvement measures. The Loviisa plant's periodic safety review is conducted every ten years in accordance with Finland's Nuclear Energy Act, with the next safety assessment to be submitted to STUK in 2030. The safety of the final disposal facility is assessed every 15 years in accordance with the Nuclear Safety Act.
