Four Networks for Geologic Hydrogen Storage

Hydrogen from renewable energy will provide opportunities for transitioning energy-intensity industries to carbon-free energy, a critical step for combating the climate crisis. Accordingly, regional and national agencies and governments are considering establishing hydrogen hubs comprising generation, storage and end-use. Geologic hydrogen storage is considered essential as the only proven large-scale storage option, but is presently confined to a few geographical regions. Establishing geologic storage in porous rock reservoirs would unlock vast and distributed capacity for hub development, but the efficiency with which hydrogen can be reversibly stored is unknown, an uncertainty that severely diminishes the commercial case for investment. This project will create four networks to address critical scientific, environmental and socioeconomic questions associated with the proposed development of geologic hydrogen storage in porous rock.
