The Canton of Aargau in Switzerland has released an online map displaying the suitability of various geothermal energy applications. This digital tool serves as a strategic foundation for investments and project development, encouraging focused utilization of geothermal resources within the canton.
Geothermal energy, particularly for shallow heat extraction through ground source heat pumps, plays an important role in fostering a sustainable and secure energy supply while supporting decarbonization efforts aimed at achieving net-zero greenhouse gas emissions by 2050.
The Cantonal Government, aware of Aargau's favorable geothermal conditions, approved a motion from the Grand Council in March 2022 to create a geothermal register to assess geothermal potential across municipalities in the canton.
Following this, the Energy Division of the Department of Construction, Transport and Environment teamed up with internal and external experts for an in-depth study of the region’s geothermal capacity.
The suitability map is publicly accessible for stakeholders interested in geothermal energy development in Aargau.
The canton’s efforts emphasize the significance of geothermal energy, especially shallow heat extraction, in reducing carbon emissions and ensuring energy security.
"Geothermal energy already makes a significant contribution to a sustainable and secure energy supply and to decarbonization (target: net-zero greenhouse gas emissions by 2050)."
The mapping project emerged from a collaborative process involving government divisions and experts to accurately pinpoint geothermal resources for municipal planning.
Author’s summary: The Canton of Aargau enhances strategic geothermal energy development by publishing an online suitability map, fostering sustainable energy and targeted investment in the region.
