North Rhine-Westphalia Pushes Geothermal Into Mainstream Heat Supply With New Deep Drilling Projects North Rhine-Westphalia (NRW) is accelerating its push to make geothermal energy a major component of the region’s future heat supply, with the state backing exploration, drilling, feasibility studies and financial mechanisms designed to reduce the risks associated with developing underground heat resources. The latest developments were presented at the 21st Geothermal Conference in Bochum, hosted by NRW.Energy4Climate and the Fraunhofer Research Institution for Energy Infrastructures and Geotechnologies IEG (Fraunhofer IEG). The conference highlighted a growing transition in NRW geothermal development: geothermal energy is moving beyond research and individual demonstration projects toward practical deployment in municipal heating, district heating networks, residential developments and industrial applications. The state has already financed measurements and drilling activities across s...
Riehen Advances Geothermal Future: Loan Application for Major District Heating Expansion By: In the picturesque border municipality of Riehen, near Basel, Switzerland, a significant step forward in sustainable energy is underway. On March 5, 2026, the Government of the Canton of Basel-Stadt and the Municipality of Riehen jointly submitted a request to their respective parliaments: approve a conditionally repayable loan totaling CHF 15.2 million (approximately USD 19.4 million at current rates) to support the expansion of the local geothermal district heating network. Each entity—canton and municipality—proposes to provide CHF 7.6 million to the Wärmeverbund Riehen AG (WVR) , the operator of the system. This funding targets the ambitious “geo2riehen” project, which aims to scale up one of Switzerland’s oldest and most successful deep geothermal heating operations. Riehen has been a geothermal pioneer since 1994, when its first plant began delivering renewable heat extracted from de...
