Hydrogen storage in depleted gas reservoirs

Researchers in the School of Engineering and Innovation recently published a paper on H2 storage in depleted gas reservoirs with CO2 in a lateral orientation to reduce gas mixing. This work, which was a collaboration with the University of Edinburgh and C-Questra, uncovered benefits and trade-offs associated with range of H2 storage conditions. Large-scale H2 storage in depleted hydrocarbon reservoirs offers a practical way to use existing energy infrastructure to address renewable energy intermittency. Cushion gases often constitute a large initial investment, especially when expensive H2 is used. Cheaper alternatives such as CO2 or in-situ CH4 can reduce costs and, in the case of CO2, integrate within carbon capture and storage systems.
