Dutch state owned Gasunie has joined the consortium of Danish Energinet.dk and Dutch and German TenneT to study the possible development of a wind power hub in the North Sea. The power hub will consist of one or more large-scale artificial island(s) for sustainable energy supply in the North Sea near the Doggersbank. The island should produce 100,000 MW of wind energy. It is expected to contribute substantially to achieving the agreed European targets set out in the Paris climate agreement. If the Paris targets are to be met, it is expected that an additional 180 GW offshore wind capacity will need to be developed. According to the four TSO's these volumes will require power-to-gas solutions as energy transport in gas-form is cheaper than transportation through the electricity grid. The island is to be situated in a location with favorable winds and the possibilities of tie-ins to offshore wind parks. Power surpluses will be converted to hydrogen for large-scale transportation to shore or for storage purposes. Gasunie will contribute its gas transport expertise and its expertise in the field of hydrogen conversion and gas storage. Gasunie an TenneT are already combining forces to develop a factory for the conversion of solar and wind energy into hydrogen in the Dutch city of Zuidwending. The hydrogen is expected to be used for municipal busses. If the North Sea Wind Hub is deemed feasible, construction is expected by 2030-2050.
