ammonia (NH3) is cheap and plentiful
run it over iron (Fe) and you release the hydrogen
I disagree that ammonia production is cheap. It uses natural gas. It requires high temperature and pressure. None of this is cheap.
The following is from google on ammonia production:
High temperatures (~500°C) and high pressures (150–300 bar) are required to activate catalysts and optimize the ammonia formation rate. However, these conditions can still limit the reaction’s efficiency to 10%–15% The Haber process combines nitrogen from the air with hydrogen from natural gas (methane) to produce ammonia using an iron metal catalyst. The ammonia is usually removed from the gas stream by cooling condensation, and any unused reactants are recycled back to the reactor.
currently, unleaded gasoline costs $2.95/gal to produce.
1 gallon of gasoline will push an average car about 25 miles.
ammonia costs $1.70/gal to produce.
1 gallon of ammonia mixed with iron will produce 0.413 kilograms of hydrogen in about 5 minutes.
the avg hydrogen combustion engine going 60 mph for 1 minute requires 0.0167 kilograms of hydrogen.
0.413kgs of hydrogen would last about 25 minutes.... which is about 25 miles.
