Geothermal Suitability Map Published in Aargau, Switzerland
The Canton of Aargau in Switzerland has launched an online geothermal energy suitability map to encourage regional development. This map highlights the viability of various geothermal application models, forming a strategic basis for both investments and project planning.
Purpose and Impact
The new map aims to support the targeted use of geothermal energy within the canton. Geothermal energy, particularly shallow heat extraction through ground source heat pumps, already plays a key role in promoting sustainable energy supply and achieving net-zero greenhouse gas emissions by 2050.
Government Initiative and Research
Recognizing Aargau’s favorable geothermal conditions, the Cantonal Government approved a motion from the Grand Council in March 2022 to establish a geothermal register. This register is designed to assess geothermal potential across the canton’s municipalities.
Following this, the Energy Division of the Department of Construction, Transport and Environment collaborated with internal and external experts to conduct a detailed investigation into Aargau's geothermal capacity.
"Geothermal energy – especially for shallow heat extraction using ground source heat pumps – already makes a significant contribution to a sustainable and secure energy supply and to decarbonization (target: net-zero greenhouse gas emissions by 2050)."
Access to the online map enables stakeholders to identify promising areas for geothermal investment and development.
How to Use the Map
- Explore different geothermal energy application models suitability.
- Locate areas with high geothermal potential for project development.
- Make informed investment decisions based on strategic data.
