In order to achieve ambitious climate targets, a rapid expansion of renewable energy generation is essential. The German market still has great offshore potential in this respect. However, regenerative expansion makes no sense if the corresponding transport or storage capacities are lacking. TSCNET shareholder TenneT, the Dutch-German transmission system operator (TSO), is already known for its sustained efforts to significantly expand the transmission infrastructure in its control area as environmentally friendly as possible. But the TSO is also very active in the development of storage concepts, just consider, for example, the storage potential of the North Sea Wind Power Hub project or the “ELEMENT ONE” power-to-gas (PtG) pilot plant.
Together with Siemens and Shell, both global players in their respective fields, Tennet is now making additional efforts to promote the renewables as well as PtG. The three companies are convinced that green hydrogen will play a decisive role in the future energy mix as the basis for many power-to-X applications, which are technologies for storage and other uses of surplus electricity. TenneT, Siemens and Shell have thus commissioned a study on a new type of tender model for offshore wind capacity. This model intends to link the awarding of contracts for the operation of offshore plants to the production of hydrogen: The additional wind power from such facilities should not put too much strain on the onshore grid, but rather be used to generate hydrogen and even stablise the electricity grid. The green hydrogen can be transported via the gas grid and then be used in other sectors, such as industry or mobility.
Lex Hartman, Managing Director of TenneT, is determined to not squander any potential for renewable energies and convinced that PtG technologies provide flexibility, reduce the strain on the grid and make power supply more secure. “In the long term,” Mr Hartman continues, “the combination with hydrogen production can also be applied throughout Germany to other renewable energies. This advances the energy transition and helps to achieve our climate targets.”
