CGG, University of Edinburgh commence ‘game-changing’ hydrogen storage research

Offshore staffPARIS, France – CGG and the University of Edinburgh have commenced an “industry-leading” project to undertake research into the subsurface storage of hydrogen in depleted gas fields.Hydrogen can be generated from electrolysis using renewable energy sources (‘green hydrogen’) and can help to alleviate the intermittent nature of renewable energy such as solar and wind. Alternatively, ‘blue’ hydrogen can be generated from gas (methane). CGG says that there is currently considerable interest in replacing traditional fossil fuels, like natural gas, with hydrogen in many industries, including energy and manufacturing and for domestic heating.However, hydrogen has a very low energy density, meaning huge volumes are required to replace methane, and making surface storage impractical. Subsurface hydrogen storage in depleted gas fields may offer a…
