The BL-740 metal hydride has a Hydrogen Capacity of 740-822 standard liters (28.2-31.28 scf) and a recharge time of ~48 hours.
If you want to see a pressure-composition isotherm and a pressure-temperature Van't Hoff plot for each alloy, click the link for the alloy of interest: Alloy A or Alloys L, M, H . Alloy A contains iron and titanium. Alloys L, M and H contain rare earth metals and nickel. Alloy A is less expensive than Alloys L, M or H. This makes no difference in prices of smaller containers because assembly labor cost dominates production costs. On larger containers, we must charge extra because of higher alloy costs.
The prefix of the part number indicates the container material. BL indicates a stainless steel container, except the BL-18, which is carbon steel. CL indicates an aluminum industrial gas cylinder. Standard quick connects and relief valves are made of brass.The part number specifies the hydrogen capacity in “standard” liters (1 atmosphere absolute pressure at 0 ℃ ). CL-370A means 370 standard liters of hydrogen capacity from Alloy A, the standard alloy for this container.The alloy choice is added to the part number, for example BL-30M or CL-370A.

All hydrogen containers ship empty (unactivated).
|Hydrogen Capacity - Alloy A||822 standard liters (31.28 scf)*|
|Hydrogen Capacity - Alloys L, M, or H||740 standard liters (28.2 scf)*|
|Hydrogen Pressure when Charging or Discharging||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 (1-10 bar at room temperature), Alloy L (2-3 bar at room temperature), Alloy M (4-5 bar at room temperature) and Alloy H (8-12 bar at 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.|
|Recharge Time||~48 hours - The specified recharge time is for cooling by still air at 20℃ and the charging pressure specified in the SOLID-H™ manual for Alloys A, L, M or H. A fan will shorten charging time.|
