Yes. And I'm not certain hydrogen can be stored safely at 10,000 psi
Somewhere up around that compression ratio, hydrogen will spontaneously combust if the pressure is suddenly released. Maybe it's 20,000 psi, not sure.
If a car got in an accident and the hydrogen tank was punctured, there would not have to be a spark to ignite it. It would simply spout a flame, and the next stop for the car would be low-earth orbit.
