But hydrogen has huge maintenance cost. - Filters need to be replaced. - Moving parts need to be serviced like the Hydrogen pressure pump. - The fuel cell itself has degradation and will lose it's efficiency. (funny thing is, it already has a very lower efficiency) I have worked with hydrogen in school. And it's so funny how much details people forget which actually impact the WHOLE idea of hydrogen solutions. I am sure it will never take off, just because it's already against the limits of the laws of nature. Unlike chemical batteries. Also to store energy, most efficiënt and cheap way to store mass ammounts of energy is in gravity. Current applications have a back and forward efficiency (Charging/decharging) energy of 85%. While hydrogen probably has a maximum of back and forward efficiency of maybe 20%-30%. While waisting the other 70%. Please. Don't read hydrogen propaganda. Read implementations and read the math. And then do the math yourself instead of following the hype of fake hydrogen news.
