I can literally see it in the linked graph. Generation from coal has been decreasing continuously since 2013. Until 2020, since then it _increased_ while nuclear generation decreased. Generation from coal might have just kept on decreasing

One thing that makes me speculate that fuel cells will play an important role in the future is: the future electrical grids based on, say > 85 % renewables, will be a challenge to keep balanced 24/7. In order to deliver enough elect
