Underground storage for decarbonisation: Hydrogen, carbon dioxide, and natural gas

Achieving net-zero carbon by mid-century requires significant CO2 emission reductions, leading economies to adopt various strategies to minimize their carbon footprint. Apart from the active build-up of renewables, popular measures include converting from coal to natural gas and investing in hydrogen and carbon capture and storage (CCS) technologies. Consequently, hydrogen, carbon dioxide, and natural gas will likely be used concurrently in the foreseeable future, making large-scale underground storage of these gases crucial. This study investigates the technical and economic feasibility of simultaneously storing methane, hydrogen, and carbon dioxide, examining geological requirements, costs, revenue potential, and the broader implications for the energy system.
