Abstract:
The individual as well as the national energy demand represent cyclic processes with quite stable daily and seasonal cycles. Using a substantial higher amount of fluctuating energy sources like wind and solar power, it stays increasingly more difficult to harmonize cyclic processes of power supply and power demand. One of the key factors for managing this dilemma will be energy storage on large scales. The subsurface provides several options for the short- and long-term storage of energy carriers and thermal energy of a substantial order. Moreover, geological storage of waste products of energy generation processes (like CO2) based on classical but recently attracted to criticism technologies, e.g., focusing on fossil fuels provides additional opportunities to foster the reduction of greenhouse gas emissions.
This session addresses several scientific questions of large-scale geological storage of energy carriers (e.g., hydrogen storage in salt caverns), waste (e.g., aquifer storage of carbon dioxide), and thermal energy. Contributions are focused on exploration and monitoring techniques, site characterization, computational process analysis, and the evaluation of environmental impacts of the considered geotechnologies.
