Metal hydrides are the most compact way to store hydrogen (more dense than liquid hydrogen). The internal volume of the CL-370A is less than 0.7 liters. 370 liters of hydrogen capacity is more than 500 times the size of the container!
Standard SOLID-H BL-series containers hold 18, 20, 30, 120, 220 or 740 standard liters of hydrogen gas. These are on the shelf or available on short delivery schedules.
SOLID-H CL-series containers, including CL-370 and CL-910, based on aluminum industrial gas cylinders. These two containers hold 370 and 910 liters of hydrogen respectively. The aluminum cylinders used to make the CL-series are rated for very high pressures. This makes them heavier than equivalent thin walled stainless steel BL-series containers of comparable capacity.
If you need a different capacity or special pressure-temperature specifications, just email your specifications. HCI has built custom metal hydride systems since 1978 with up to 300,000 liters of hydrogen capacity.
A SOLID-H™ container is coupled to your system by a fitting that you specify when you order. This is usually a quick connect for convenience of installation and removal. Unless you specify a different fitting we will install a Swagelok QM series female quick connect on the container. We also supply a mating male quick connect that adapts to 1/8 th inch tubing.
The hydrogen pressure when charging or discharging a SOLID-H™ container is something you select when you order. Four standard pressure ranges are offered; Alloy A(see Alloy A), Alloys L,M and H(see Alloys L,M,H).
Alloy A is an iron-titanium alloy that may be shipped void of hydrogen as non-hazardous material. Alloys L, M and H are rare earth-nickel alloys. After activation (activation means "charged for the 1st time") they must be shipped void of hydrogen as a flammable solid. The expense of hazardous shipping may be avoided if you order unactivated SOLID-H™ containers. HCI will send activation instructions.
Recharge your SOLID-H™ container by connecting it to a source of clean dry hydrogen gas at the pressure specified in your SOLID-H™ manual. The container will get warm to the touch. When it is cool again, recharging is complete.
Reduce the pressure to the value indicated for your alloy in the SOLID-H TM manual before disconnecting it from your hydrogen source. Failure to do so may lead to venting through the pressure relief in hot environments (pressure increases rapidly with temperature).
