Hydrogen vs. Battery Electric Cars

While I agree that there will be a place for hydrogen fuel cells, especially for large scale long distance vehicles such as ships, I think for cars, BEVs have already won this race 9yes, I do think this is a race and there really are winners and losers).  I think you undervalued the issue with efficiency and wrote off charging at home pretty quickly.  Given that hydrogen fuel cell vehicles have 1/3 to 1/2 the efficiency of BEVs, it would require a massive increase in electricity generation to go to a predominantly fuel cell technology.  This will take a lot of time that we unfortunately cannot afford, given the state of the planet.  Time will also be required to build out the fuel delivery system.  You essentially ruled out home charging because not everyone can install a charger.  This could change with appropriate legislation and incentives.  Besides that, it is perfectly feasible to charge from a standard electric plug overnight for most commute distances.  I did this for a year with no issues before I had a charger installed.  There are plenty of innovations that can help people with limited charging options, such as charging infrastructure at on street parking locations.  In the UK, they have charging points built into lamp posts.
