Hydrogen solar panels to enable hydrogen cars and home power supply

Will the anti-EV campaigners object to hydrogen EVs.  He mentions internal combustion engines, but in truth, hydrogen cars will use fuel cell drive systems.  The problem as always with hydrogen will be the storage of the hydrogen.  This video hardly mentions this issue.  Pressured hydrogen is difficult and the hydride system need Lithium-6, the sale of which is effectively banned as it is a substance used by the nuclear power industry.  Toyota is talking of cars running on ammonia – NH3 – by 2027 but the problem right now would be the high cost of the fuel.
