BL - Model 30 -Metal Hydride

The BL-30 metal hydride has a Hydrogen Capacity of 30-34 standard liters (1.14-1.3 scf) and a recharge time of ~4 hours. ALLOY CHOICES 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.
