Blue Battery, a spin-off from PhD research at Utrecht University, on 3 October 2018 presented its plan for an underground energy buffer in the Dutch province of Limburg. Research has demonstrated that it is both essential and feasible. Experts from science and industry and a project team have started preparations so that construction work can begin in two years’ time.
The use of wind and solar power is set to grow substantially. However, extreme fluctuations in production will give rise to problems, such as when there is no wind and the sun does not shine. Measures are needed to be able to compensate for these fluctuations in electricity supply, not only to be able to produce as much green energy as possible, but also to mitigate the risk of a black-out.
