Hydrogen storage in depleted gas fields is an area of joint research between CGG and the University of Edinburgh’s GeoEnergy research group.
To compete with fossil fuels like natural gas, hydrogen will need large-scale, low-cost, and dependable hydrogen storage solutions. The new group is exploring the feasibility of reusing depleted gas reserves for this purpose.
To model the variety of the depleted gas fields’ underground geological reservoirs, they plan to work together. That way, they can see which ones have the best potential as hydrogen storage locations. Additional options, such as the utilization of carbon dioxide and other alternative cushion gases, to reduce operational storage will also be investigated.
The project’s findings are seen as critical to the energy sector’s and regulators’ plans for expanding hydrogen use.
