Studies find smaller energy islands to be most efficient

The international consortium behind the North Sea Wind Power Hub (NSWPH) has presented findings from the project’s assessment phase, calling for a gradual roll-out of 10GW to 15GW hubs.

The partners, including TenneT, had been analysing the conditions required to build one or several wind power hubs in the North Sea, as it looks to drive a large-scale roll-out and integration of North Sea wind. Its proposed Hub and Spoke concept was found to be technically feasible. Furthermore, a first Hub and Spoke project is likely to be electrically connected to shore, with additional power-to-gas to provide energy system flexibility, and potentially operational in the 2030s.

Longer-term, the consortium said that an implementation of 180GW offshore wind can be achieved by 2045 if its approach is followed.

However, changes are needed to national practices, approaches, planning and policies to allow for integrated infrastructure projects being part of the long-term energy transition, while the consortium also stressed urgent agreements on developing sustainable energy from offshore wind post-2030 are needed.
