UK firm Nationwide Grid has revealed it’s in talks with two different events about constructing an “power island” within the North Sea that may use wind farms to produce clear electrical energy to thousands and thousands of houses in north-west Europe.
The thought of a renewable power hub within the North Sea has been floated for years, however has but to progress from research to actuality. The idea envisages offshore wind farms which have a a lot bigger capability than these in use immediately, with sub-sea electrical energy cables taking the power to whichever nation wants it most.

Nationwide Grid is a significant developer of such long-distance cables within the area, most lately one from Norway to the UK, so its involvement in talks with different power companies will increase the possibility of the thought being developed.
“We’re in tripartite discussions over an power island that the UK would seemingly connect with,” says Nicola Medalova at Nationwide Grid. She wouldn’t title the 2 different events the corporate is speaking to. A spokesperson for Nationwide Grid additionally declined to substantiate the events concerned.
“There at the moment are a variety of power island ideas being promoted by totally different events in international locations similar to in Denmark, Belgium and the Netherlands, and we’re in conversations with all of them to grasp the ideas on the market,” stated the spokesperson.
Different power community operators across the North Sea have signalled their curiosity in constructing an power island, together with Elia in Belgium and TenneT within the Netherlands.
Two years in the past, TenneT concluded that such a venture could be technically possible, regardless of the engineering challenges. Nonetheless, the corporate tells New Scientist that it isn’t in “concrete” talks with Nationwide Grid about an power island. Belgium’s power minister, Tinne Van der Straeten, stated in Might that the nation would construct an island to “interconnect our wind generators”, constructed by Elia.
A spokesperson for Elia says it’s growing a second electrical energy interconnector cable between the UK and Belgium, generally known as Nautilus, however “whether or not Nautilus shall be related to the Belgian power island is at present unsure.”
Denmark has additionally proven a powerful curiosity in constructing an power island, with the Danish authorities saying in February that it will assist finance a £24 billion island to the west of the nation. The Danish imaginative and prescient sees a key position for wind energy to additionally generate “inexperienced hydrogen”, because the nation appears to new exports following a ban on new oil and fuel fields.
Medalova says power islands may both be constructed on an current pure island or a purpose-made synthetic one. “You set a lot of totally different applied sciences, maybe in a single house – you may have wind, hydrogen, battery storage, all the remainder of it, and that may be related to 1 nation, two international locations,” she says. She provides the venture being mentioned is taking a look at “three connection factors”, a sign that three international locations are concerned.
Kees van der Leun of Netherlands-based consultancy Frequent Futures says: “Connection by way of an power hub between the UK and the Netherlands and Belgium, or the Netherlands and Denmark, will surely add worth. That is due to the large build-out of offshore wind within the UK, and the time distinction in wind peaks between the UK and the continent.”
Whichever international locations the island is related to, they might all reap the benefits of the low-carbon power generated by tons of and even hundreds of generators. The power island may very well be constructed earlier than 2030, says Medalova, which might give an enormous increase to the promise that UK prime minister Boris Johnson made this week of a completely inexperienced nationwide electrical energy grid by 2035.
Potential areas for the island haven’t been disclosed. Nonetheless, TenneT has beforehand talked about utilizing the shallows of Dogger Financial institution, a sandbank off England’s north-east coast and a remnant of when the UK and continental Europe had been one land mass.
No matter whether or not an power island materialises, Nationwide Grid expects that almost all new electrical energy interconnectors it builds shall be “hybrid” ones that hyperlink two international locations but in addition connect with offshore wind farms in between. The world’s first hybrid interconnector was inaugurated final 12 months, connecting offshore wind farms to Denmark and Germany.
Medalova says this summer season the UK authorities has been encouraging wind farm builders and interconnector corporations to work collectively on such tasks to cut back the influence on folks dwelling on the coast from new offshore wind farms, which usually require particular person connections.
“My intestine feeling tells me that every one our new interconnectors shall be hybrid,” says Medalova. “The best way that politics is shifting, the best way that expectations of coastal communities is shifting, the best way that the market is shifting, there may be such an enormous expectation we’ll take this collaborative, sharing method.”
