The Danish energy ministry plans to build “energy islands,” which would make Denmark home to the world’s largest renewable energy scheme.
The new concept involves developing artificial platforms which would connect offshore wind turbines. The scheme is set to cost between £22.5bn and £33.8bn, with private investors covering most of the cost.
The ministry said each completed island would produce 10GW of power. That would cover the electricity for 10M houses in Denmark.
It would be the latest addition to Denmark’s offshore wind programme, where the first wind turbines in the world were built in 1991.
Climate and energy minister Dan Jørgensen said Denmark needs to “build more than five times as much [renewable] capacity as we have today”.
“Offshore wind is central to the green transition,” he added. “If we seriously need to realise the enormous potential of offshore wind, we must develop tomorrow’s technologies to transport the green power fuel for aircraft, ships and industry.”
It is not clear where the islands would be built, but the ministry confirmed it was considering locations in the North and Baltic Seas.
The plan comes a week after Denmark passed legislation promising 70% emissions reductions by 2030, and carbon neutrality by 2050. The EU target, in comparison, is to cut emissions by 40% by 2030.
Denmark’s annual budget meanwhile includes £7.3M for research into methods to convert wind energy into renewable hydrogen.
The country produced 41% of its energy from wind power in 2018, which was the biggest proportion in Europe.
