It's been over 20 yrs since I watched Alan Alda cover the new hydrogen storage tank tech with what looked like large carbon hockey pucks, this enabled safer "quick filling", disappeared....& lets not ignore that it takes a bunch of electricity to generate significant amounts of hydrogen from water, the only real real safe & plentiful source. Believe Me, I'd love to see hydrogen become a feasible fuel, it just ain't yet. & that's for real..
