Is underground energy storage an option for decarbonizing energy systems?

Renewable energy systems will play a pivotal role in reducing greenhouse gas emission and achieving the net zero target in most nations. However, they have intermittent energy production that may not necessarily align with energy demand. Energy storage has the potential to optimize the integration of renewable and renewable energies and to contribute to sustainability of energy systems. Storing energy in subsurface geological formations can lead to a safe, large-scale, and long-term solution for transition to the low carbon energy systems. Recent advancements in understanding of interactions among water, porous rock, and stored gas phase in the context of natural gas and CO2 geological storage have shown the potential of underground systems for storage purposes. However, there is still crucial to further increase our understanding of subsurface energy storage potential. In this project the objective is to investigate the opportunities and challenges of underground energy storage (thermal, compressed air, hydrogen, etc.). The student will also require exploring both national and international databases to collect information which help them to draw a realistic picture of underground energy storage position and contribution in mitigating the current global challenge.
