Jordkraft Energy AB and the Royal Institute of Technology (KTH) have signed a memorandum of understanding to strengthen collaboration in geothermal power research and development. The partnership will focus on advancing technology, market analysis, modelling, and the design and testing of key components.
The agreement also opens doors for student exchanges, internships, and thesis projects, while the two parties plan to jointly seek external funding through national and international programs.
Under the supervision of Professor Andrew Martin at KTH’s Department of Energy Technology, Division of Heat and Power Technology, and in close collaboration with Johan Asplund, CTO at Jordkraft, KTH conducted a pre-study during the spring led by master student Maulida Rahma.
The study explores how Jordkraft’s system can be deployed in practice. It compares different technical approaches for converting heat into electricity and evaluates how temperature, flow, and pressure affect system performance.
The findings, presented in June 2025, confirm strong potential for the concept and identify critical areas for further development, including heat exchangers, pumps, and control systems. Prototype testing of these components is recommended as the next step.
“Working with Jordkraft allows us to connect cutting-edge research with real industrial needs,” says Professor Andrew Martin of KTH.
“This collaboration combines advanced system analysis with practical component development while giving students hands-on experience in energy projects that address one of today’s most pressing challenges: meeting growing electricity demand while achieving climate goals.”
“Sweden is a country known for innovation, but we’re falling behind in geothermal power despite its huge potential to replace fossil fuels,” adds Jessica Friberg, CEO of Jordkraft. “Targeted investments are needed to strengthen Sweden’s and Europe’s competitiveness as the global energy landscape shifts. Jordkraft’s unique solution offers a pathway to clean, reliable baseload power.”
