One of the pressing challenges for the 21st century is a secure, sustainable and economical energy supply at simultaneous mitigation of its climate impact. Besides a switch to renewable energy resources, the exploration and exploitation of new, unconventional energy resources will play a major role as will the further use of fossil fuels. With the switch to renewable energies the question of geological energy storage will become an important topic whereas further use of fossil fuels requires strategies like CCS to reduce its negative climate impacts. These different aspects of geo-energy create complementary or competitive requirements on the subsurface and its use. It is therefore essential to treat the subsurface as a geo-resource of its own right. The session aims at providing a holistic approach and view on the different aspects of geo-energy with a focus on geothermics as an example of renewable energy, shale gas as an example of unconventional energy resources and CCS as the key challenge for further use of fossil fuels. Contributions from experimental, theoretical, and numerical studies as well as from field laboratories or natural analogues are welcome and should focus on the complementary or competitive requirements on the geo-resource subsurface.
