Element One Energy - Model BL-740 -Metal Hydride Hydrogen Storage Container

SHARE
The BL-740 Metal Hydride Hydrogen Storage Container is an advanced solution for solid hydrogen storage, boasting a capacity of 740 standard liters (28.2 scf). Made from high-quality stainless steel with brass fittings, it combines durability with precision engineering. This container has a cylinder diameter of 4.6 inches (117 mm) and an overall length of 8.1 inches (206 mm), weighing in at 12.1 lbs (5.5 kg). A robust structure is confirmed with a destructive proof test rating exceeding 2400 psig (160 bar) and a pressure relief valve set at less than 550 psig (37 bar). The container's discharge rate is variable and relies on system requirements, suggesting hours to withdraw 90% or more of the hydrogen. Recharge time under standard conditions is approximately two days, which can be expedited using a fan. Tailored for users needing reliable hydrogen flow, this storage container is adaptable via SOLID-H™ metal hydride alloys, making it an efficient and resilient choice for solid-state hydrogen applications.

Note 1: 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.

Note 2: 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.
