Denmark has approved a plan to build an artificial island in the North Sea that will be a hub to hundreds of offshore wind turbines, 260m tall, that will generate 10GW, enough energy for 10 million households. The first stage will be the size of 18 soccer pitches, for 3GW, costing €29bn ($34bn), and should be operational by around 2033. Writing for the World Economic Forum, Douglas Broom says that the ultimate goal of 10GW should be more than enough for the whole of Denmark. The spare capacity will be used both to sell on to other nations and to create green hydrogen from sea water. Large batteries on the island will also be used to store surplus electricity. The sheer scale of the project can be a driver for multiple technologies and a model for other coastal nations as global offshore wind installations continue to rise. Ambitious projects like this are needed if the EU wants to hit its renewable electricity targets and increase offshore wind energy capacity 25-fold by 2050. Broom ends by quoting the Chairman of Ørsted, the wind farm major, as saying that offshore wind should also be seen as an opportunity to work with other ocean-based sectors like mariculture and fisheries.
