Just looking at Metal Hydrides. You can if you had "VERY" deep pockets buy them now.
Metal Hydrides

Hydrogen Pressure when Charging or Discharging Alloy A, Alloy H, Alloy L, and Alloy M hydrides require the hydrogen charging pressure of 400 psig, 400 psig, 100 psig, and 200 psig, respectively. The discharging pressure during the discharge cycle would be very similar to the respective charging pressure of the selected hydride (assuming that stored hydrogen gas is not vented instantaneously). The SOLID-H™ container will become hot to the touch as it absorbs hydrogen (during charging stage). Charging is complete when it has cooled to room temperature. Discharge Rate The discharge rate depends on many variables. We can help you select a SOLID-H™ metal hydride alloy and hydrogen container(s) that will meet your hydrogen flow requirements. In general, you should not expect to empty the entire hydrogen capacity in a matter of minutes. Hours are required to withdraw 90% or more of the hydrogen capacity from a standard** metal hydride container. The largest SOLID-H™ containers require days to discharge completely. **It is possible to discharge a metal hydride in a matter of seconds. This requires extraordinary heat transfer enhancement inside and outside of the container. We can provide heat transfer enhancement to improve the charging and discharging rates of our SOLID-H™ containers.
Bold two aspects which are expected yet not often highlighted. Vent a gas cylinder or gas cartridge and we have all seen it.
LAVO Triva- Named after "Antoine Lavoisier the scientist who named Hydrogen H1." Other trivia is Mr Lavoisier got the guillotine during the French revolution.
