When you are willing to sit down and get technical ... numbers are numbers ... there are usually pros and cons to both sides of allot of issues ... including hydrogen as an energy carrier ... unfortunately there are allot of people who do not like to get technical ... and allot of people get defensive when questioned about the basis , and reasons for their opinions.
Hydrogen has 2 major benefits:
#1> Cleaner at point of use... very few are better.
#2> Energy density weight kwh / kg... very few are better.
Hydrogen has 2 major disadvantages:
#1> Efficiency ( Produce the H2 , distribute, store , use )
#2> Energy density volume kwh / L ... many are far better.
Progress has been made ... but it is slow and is a long way off at best ... I also think BEVs from RE are a more ultimate direction ... and are already more developed and advanced than the hydrogen system.

There's no room for error with highly pressurized hydrogen.

You might be surprised to find how common Highly Pressurized Hydrogen already is ... especially in some commercial , industrial, and scientific facilities.
I've seen some eye opening things ... including an entire tractor trailer full of 10,000 PSI hydrogen being disconnected, swapped out, and reconnected ... buy a guy with a lit cigarette hanging from his mouth the whole time.
About ~2 years ago a competing propane provider gave us bids, and they offered Hydrogen as well ... and did not require anything different than what was needed for propane... to sell or supply us with highly compressed or liquefied hydrogen... there was even a company who gave us a bid to convert the propane ICE forklifts to run as hydrogen ICE forklifts.
