Belgium plans artificial island to store wind power
‘ Belgium is planning to build a doughnut-shaped island in the North Sea that will store wind energy by pumping water out of a hollow in the middle, as it looks for ways to lessen its reliance on nuclear power. One of the biggest problems with electricity is that it is difficult to store and the issue is exaggerated in the case of renewable energy from wind or sun because it is intermittent depending on the weather.’ ‘The island is still in the planning stages, but will be built out of sand 3 km off the Belgian coast near the town of Wenduine if it gets the final go-ahead. The island, which would also work as an offshore substation to transform the voltage of the electricity generated by wind turbines, could take five or more years to plan and build.’
