Danish-led group plan North Sea wind power hub

The Centre for Electric Power and Energy at the Technical University of Denmark (DTU) is leading a research project to determine the technology needed for an artificial island to connect North Sea wind farms to surrounding countries.

The group plans to build the North Sea wind power hub "somewhere between the Netherlands, Germany, the UK, Denmark and Norway"

Along with project partners including Energinet, Vestas, MHI Vestas, Siemens Gamesa, ABB, NKT, Siemens and Ørsted, DTU then plans to develop the technological solutions required to make the hub feasible.

It launched the research in January and aims to have reached firm conclusions about required technological innovations by August 2020, a DTU spokesman told Windpower Monthly.

DTU said new energy transfer methods and storage options would be needed, the DTU added.

It plans for the hub to be built in modules, with individual islands capable of connecting up to 30GW of offshore wind capacity, and the entire project capable of connecting up to 180GW in total.

"We need to quickly start mapping the technological challenges we need to overcome when establishing the new energy solutions," said Jacob Østergaard, head of DTU’s department of electrical engineering.

The Danish Energy Agency’s Energy Technology Development and Demonstration Programme has awarded a grant of €295,000 for the North Sea Power Hub. 

A DTU spokesman told Windpower Monthly this total would be sufficient to cover the research part of the project.

The idea of using artificial islands to link North Sea countries with offshore wind farms has been considered before.

Danish operator Energinet, one of the DTU’s partners on the project, is also working with Dutch TSO Tennet to develop a wind power hub in the North Sea.

Meanwhile the UK’s Oil and Gas Authority is exploring the potential of creating artificial islands on which wind-generated electricity and hydrogen can be produced.
