You recently said that storage is the ‘weakest link’ in Europe’s electricity chain today. Could you explain why that is?
Our electricity chain, or indeed our whole energy chain, is integrated in a very complex way. Everybody treats it as if it were the sum of individual silos and nobody tries to build intelligent bridges or links between them. Storage could be a fantastic bridge, making sure we get higher efficiency at lower cost. It has huge potential. Having said this, we should never forget that storage – by definition – has negative efficiency and excessive costs. You don’t want to store for the sake of storing. You only want to store if the alternative solution is even more expensive – for example expanding the grid. That holds both for large-scale and small-scale or local storage.
