It’s naturally leaky and requires very high storage pressures poses a problem for infrastructure. At present, it does not seem worth incurring all the risk just to “be green”.
However Ive got no problem with continuing to pursue and develop the tech like Toyota is doing with the Mirai.
What's cool about hydrogen is actually the storage because for a lot of uses you don't need very high pressure. For example if you wanted an off-grid power supply for your house there's no reason you couldn't get a fuel cell and a week's worth of lower pressure storage tanks for a few thousand or maybe less even.
It's a whole different tradeoff from batteries. Hydrogen is cheap hardware and expensive energy, battery is expensive hardware and cheap energy.
I suppose eventually we'll have cheap batteries made from graphene or whatever, but that might be a long way off.
There's hardly any unsolved problems with hydrogen. Basically just fuel cost, infrastructure, and exploding.
Fuel cost and infrastructure might could happen if it were given the same subsidies as EVs.
The exploding is a real problem, but it's hard to say for sure if it's overall worse than EV problems.
