Problem with hydrogen is that it can not be practically stored and can not be practically transported . Plus the molecules are so small hydrogen creeps through pressure vessel wall materials.
The cost , time and energy to fill pressure vessels to 3000, 4500 or 6000psi makes H2 prohibitive . That energy used to compress is lost as heat .
The pressure vessels are also large , heavy and awkward to fit into a vehicle chassis .
Producing H2 from any source is expensive . The best source of H2 is to build enough nuclear power plants to operate the nation during daytime peak . Then the surplus capacity
during off peak to produce H2 from water .
Plan B would be to use off peak steam mixed with natural gas in the presence of a catalyst to produce clean burning alcohol.
Alcohol is relatively cheap and simple to store and use at atmospheric pressure and at ambient temperature .
