Hi Jack you never mention your view on PLUGs electrolyser market strategy I agree on the fuel cell front - MH and not datacenter or stationary but how about electrolysers? Does it make sense for AMazon to install at large hubs? more importantly as this is where the market is how about Europe and Africa. what type of customer is a potential sale for electrolysers - Lhyfe seems to have a niche and there are others.
