Gas Storage Denmark (GSD), which is part of Energinet, is already operating Denmark''s two underground gas storages and has more than 30 years'' experience with large-scale underground storing of energy and brings this experience into the project. The hydrogen storage currently being outlined includes a capacity of 200 GWh green energy.
Such capacities can only be supplied by underground cavern gas storage — for example, Denmark''s natural gas storage capacity is ~12 TWh. In addition to seasonal storage, a robust energy storage concept will also facilitate faster integration of renewable fluctuating energy (solar and wind), as greater seasonal variations can be covered by ...
