Jordkraft Energy and KTH Launch Operational Research Collaboration
Jordkraft Energy is strengthening its technology development together with KTH Royal Institute of Technology by launching an operational research initiative focused on high-temperature geothermal energy.
The initiative will strengthen Jordkraft Energy’s technical decision-making framework and provide advanced analytical and design support for upcoming pilot facilities.
As part of the initiative, two research students from KTH Heat & Power, Jenny Stolt and Naomi Mare, will join the project. Their work includes advanced numerical modelling of heat flows in deep crystalline bedrock and temperature profiles around boreholes. They will also analyse how different design and operational choices affect system performance over time. The results can then be translated into concrete recommendations, helping reduce technical risks in early project phases.
“This will give us a more robust design basis and clearer guidance as we move towards our future pilot plants,” says Johan Asplund, founder and CTO of Jordkraft Energy.
Andrew Martin, Professor of Energy Technology at KTH, highlights the link between academic excellence and industrial application:
“By combining KTH’s modelling expertise with Jordkraft Energy’s system concept, Jenny and Naomi can translate fundamental heat transfer physics into practical guidelines. This is exactly the type of applied research that reduces risk in pilot phases and accelerates the development of high-temperature geothermal energy,” says Andrew Martin.
The research initiative is directly connected to Jordkraft Energy’s current project portfolio, which currently includes two Swedish feasibility studies and one international project in Ukraine.
Crystalline bedrock
Crystalline bedrock consists of hard rock types such as granite and gneiss and covers approximately 75% of Sweden’s surface area. Sweden is located on the so-called Fennoscandian Shield – a very old and stable part of the Earth’s crust dominated by crystalline rocks. Sedimentary rocks such as sandstone and limestone are mainly found in Skåne, on the islands of Gotland and Öland, and in parts of Västergötland and Närke.
