Underground storage for decarbonisation: Trade-offs between hydrogen, natural gas, and carbon dioxide

This paper examines the suitability, opportunities, and challenges associated with large-scale geological storage of natural gas, hydrogen, and carbon dioxide, focusing on the four key subsurface structures. It finds that not all formations are equally suitable for all gases: salt and rock caverns and smaller depleted fields are optimal for hydrogen and natural gas storage, while large-scale aquifers and depleted […]
