Decarbonizing Energy Supply
Avoiding / Minizing Import of Electricity
Providing Autarkic, Decentralized, Dispatachable, Baseload Thermal & Electric Power
AEGIS-CH is an Innosuisse Flagship project with the aim to improve the resilience of the Swiss energy system through the development and integration of Advanced Geothermal Systems (AGS). AGS, consisting of closed-loop wells without any hydraulic stimulation, have the potential to provide decarbonized, domestic and decentralized heat and electric power. This enables firming up an increasingly solar/wind (and thus largely only intermittently available) Swiss energy supply system, supporting the Swiss Energy Transition Strategy (SETS) 2050 as well as UN Sustainable Development Goals. Together with our academic and industry partners, new technology is developed to construct closed-loop AGS and the potential of AGS is explored in the context of the optimal energy mix. This integrated concept leads to essential AGS developments, energy policy recommendations for Switzerland and new energy business models.
