Using geologic resources to mitigate climate change
Geologic resources contain a huge potential to contribute to reach carbon neutrality and thus, mitigate climate change. On the one hand, the Earth is a source of renewable energy and provides geothermal energy that can be used for both heating and cooling purposes and for electricity generation. Unlike other renewable energies, geothermal energy does not fluctuate during day and night and along seasons, so it can serve as the base energy. On the other hand, there are industrial processes that emit CO2 even if renewable energies are used to supply electricity, such as cement, steel and ethanol production. To avoid these emissions, CO2 can be captured and subsequently stored in deep geologic formations. Despite their potential to reduce one third of the total CO2 emissions, these technologies are not exempt from issues of public concern. Indeed, induced seismicity has become widespread as a result of fluid injection in the subsurface for energy related activities. If felt, induced seismicity has a negative effect on public perception and may damage adjacent infrastructure. In this presentation, we will learn how geothermal energy production in supercritical systems and geologic carbon storage may affect fault stability. ; Peer reviewed
