> And if you think about the amount of gasoline infrastructure that exists, we'd have to pretty much duplicate that, or convert that, into hydrogen shipping infrastructure, which is a pretty tall order.
On the other hand, electrolysis can be significantly more distributed than gasoline, you don't need a limited number of refineries anymore. Hydrogen can be generated city-wise, at the station, or even (with further efficiency hit) at-home.
You need to pressurize the hydrogen to 5-10 kpsi which requires a compressor in every home, this cuts efficiency. Electrolysis is also very inefficient (%65 is usually cities as the upper efficiency[1]). Most importantly the cheapest way to produce hydrogen is through stream reformation of Carbon based fuel (high CO2 emissions req), making electrolysis cost prohibitive.
Hydrogen is not a great way to go, especially when you consider that batteries and electric motors are already very efficient. Working on energy density in batteries would be more cost effective then chasing after H2.
