Hydrogen embrittlement is a big problem for most unprotected metals and organic based plastics. Also Hydrogen molecules are real small and will leak out of the seals, posing fire/explosion hazards. There is a reason they call it "rocket science."

I got fairly exited about Ceramic Engines back in those days, 1975, (being heavily invested in "Roger Billings Hydrogen Homestead", the man is a Fraud and it is a shame, he set back Research and implementation of Hydrogen by years with his shameful pseudo Science hype)

I still think that Hydrogen is viable fuel, just not yet.
