The "issues" you list is something companies like Toyota has already dealt with and even if it's small, there is still a growing hydrogen infrastructure in some places in the world like california with people driving these cars.
Yes they are challenging, but we have already overcome and have vehicles and infrastructure in production.
I see many hydrogen critics list how hydrogen is "very volatile, able to ignite, cold as heck, extreme temperature" and etc, well yes, there are challenges, but despite that there are companies out there that have dealt with them and already have products running on the same hydrogen you are talking about.
Not trying to blindly support hydrogen or anything, but in my opinion we are past the point where we debate and claim hydrogen is not possible and has many issues - many of them are no longer an "issue" when its already out there for consumers in some parts of the world, and if these issues were a huge barrier, we won't have vehicles like Toyota mirai selling at all, so these issues are not issues but maybe "tricky", "expensive" and "slow development" would be the right words.
