Unless the makers of battery-only EVs can get around the current slow charging times, there's potential utility in hydrogen.
Even if Elon Musk calls fuel cells "Bullsh*t".
Some of the AGM batteries can charge very fast (very low internal resistance), but they’re expensive. I use low cost, flooded lead-acid batteries with thick plates for a small PV solar plant for home power.
I wouldn’t have an electric car up here, though (very risky), even if there were available grid power nearby. There are mountain passes at every exit to this area. Temps go down to the minus 30s F, and winds go over 100 mph in winter. Batteries won’t take that, unless they’re actively heated (big waste, very expensive). Bills from rural electric companies are high. There aren’t many garages around, either (vigilant property tax banditos—another cost).
Something else is lacking: powerful four-wheel-drive, high clearance, electric vehicles that will go through deep ice that drifts into dunes with the consistency and weight of sand.

I think that both technologies will improve steadily in terms of price/performance. For a couple of decades we’re going to be treated to a seriously fun/interesting competition between several large transportation systems including internal combustion/oil, natural gas/internal combustion, hydrogen/fuel cell, hybrids and electric cars— which will have the effect of bringing down transportation costs substantially. I hope they all survive because its best to have a diversity of fuels engines for load balancing reasons.
