BL-18 Metal Hydride

The BL-18 metal hydride has a Hydrogen Capacity of 18-20 standard liters (0.67-0.76 scf) and a recharge time of about 4 hours. About Solid-H Hydrides SOLID-H hydrogen storage containers are filled with metal powders that absorb and release hydrogen (metal hydrides).  You may already be using metal hydrides in your laptop computer (nickel-metal hydride batteries). The most popular SOLID-H containers supply a few atmospheres of hydrogen gas pressure at room temperature.  This is the safest method known for storing flammable hydrogen gas. If your hydrogen system develops a leak, SOLID-H immediately releases a small fraction of its stored hydrogen.  The remainder will be released over a period of hours. Typical uses for SOLID-H include hydrogen supplies for gas chromatographs and fuel storage for hydrogen engines or fuel cells. Alloy Choices If you want to see a pressure-composition isotherm and a pressure-temperature Van't Hoff plot for each alloy click here for Alloy A or here for Alloys L, M, H.  Alloy A contains iron and titanium while 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.  Larger containers, cost extra mostly due to the higher alloy costs. Ordering 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°C).  CL-400A means 400 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-400A.  Contact us if you have any questions or concerns before placing your order.
