Nine countries in Europe have drawn up plans to link clean energy projects around the North Sea to build Europe’s first electricity grid based on renewable power.

Under the plan turbines off the north coast of Scotland will be connected to solar panels in Germany and join the power of waves crashing on to the Belgian and Danish coasts and hydroelectric dams in Norway’s fjords.

The weather-proof, high-voltage direct current network could cost up to $43.14bn (€30bn) and will include thousands of kilometres of highly efficient undersea cables.

The supergrid connected to many hydroelectric power stations in Norway will act as a giant 30GW battery for Europe’s clean energy and store electricity at times of low demand.

The countries involved in the project are Germany, France, Belgium, the Netherlands, Luxembourg, Denmark, Sweden, Ireland and the UK.

The supergrid is regarded as a major step towards achieving the European Union’s target of producing 20% of its energy from renewable sources by 2020, reports the Guardian.
