Yup. The problem with hydrogen for the last 50 years has been the dismal economics, and trying to find better catalysts to make electrolysis more economical. New govenment incentives and carbon credits might push it into profitability, but it'll still be tough. The problem is I've driven enough cars that have developed gasoline/brakes/cooling/oil/exhaust/power steering leaks to know that I never want to own a thing that runs on pressurized hydrogen.

This brings back painful memories of an old boss. He was all set to send $525,000 to some company in Virginia or something because they had a seacan that just makes electrical power with no fuel. It took days to talk him out of that. What pissed me off most was I actually had to look up all the background information because he just wouldn't let it go. Spoiler: it was a motor hooked to a generator. How does one get to their 6th decade of life and not ever hear of a perpetual device before? And this wasn't even one of the creative ones. Some of them are actually kind of neat.
