Geological storage of Hydrogen for Net Zero

To meet the global commitments for net zero carbon emissions our energy mix must transition from fossil fuels. Hydrogen is gaining increasing recognition as a low carbon energy option to support this energy transition. Hydrogen is considered a low-carbon substitute for fossil fuels to decarbonise domestic and industrial heat, power generation and heavy-duty transport. It can also promote increased renewable energy uptake by acting as an energy store to balance supply and demand.

For hydrogen to be deployed at the scales required for net zero, we will need access to large-scale geological storage. This talk will present an overview of the most recent findings from research working to establish the feasibility of storing hydrogen in underground porous reservoirs. The talk will cover the results of research into the key biological and chemical reactions between the reservoir rocks, formation fluids and injected hydrogen that could compromise the storage complex and the key flow processes that influence hydrogen migration and trapping during injection and withdrawal. It will also consider the role of hydrogen storage within an integrated energy system.
