Making electricity from renewable energies storable
Climate protection and energy turnaround will lastingly change the energy landscape of Germany. With the continuous increase of renewable energies not only in the power grid, the question of the complete and efficient use of these energies is gaining in importance. The greatest challenge in this regard is to reconcile the supply of and demand for energy. Power-to-gas permits the renewable energy recovered in the power sector to be stored in large quantities and to be put to further use in a flexible manner in the form of gas. This method is thus the future technology of the power industry.
The systemic advantages of the use of power-to-gas (physical-technical storability, existing gas network and storage infrastructure) relieve the strain on the classical power sector through more flexibility and lead to cost reductions in the sectors to be developed.
Already now it is possible to store approximately 200 terawatt hours of energy in subterranean gas reservoirs – this roughly corresponds to 23,000 times the capacity of a state-of-the-art pumped-storage hydropower plant.
