Geothermal Suitability Map Published in Aargau, Switzerland
The Canton of Aargau in Switzerland has released an online suitability map highlighting the potential for geothermal energy use in the region. This map serves as a strategic tool for guiding investments and project planning to promote geothermal energy development within the canton.
Purpose and Impact
The map covers various application models of geothermal energy, supporting targeted and efficient usage. It particularly focuses on shallow heat extraction through ground source heat pumps, which already contribute significantly to sustainable energy supply and the canton’s goal of achieving net-zero greenhouse gas emissions by 2050.
Background and Development
Recognizing Aargau’s favorable geothermal conditions, the Cantonal Government responded to a motion from the Grand Council in March 2022, which called for the creation of a geothermal register to assess the potential in local municipalities.
Following this, the Energy Division of the Department of Construction, Transport and Environment collaborated with both internal and external experts to thoroughly investigate the canton’s geothermal potential.
"The map establishes a strategic foundation for investments and project developments, thereby promoting the targeted use of geothermal energy in the canton."
Access to the Suitability Map for Geothermal Energy is provided online to facilitate informed decision-making.
Significance for Sustainability
Geothermal energy, especially through shallow heat extraction, plays a crucial role in ensuring a secure, sustainable energy supply and aiding the canton’s decarbonization efforts by 2050.
