Hydrogen storage

Metal hydride hydrogen storage canisters are designed with an aluminium alloy materials enclosure and a ReNi5 alloy for hydrogen absorption. After activation (see instructions for activation process below), the ReNi5 alloy can absorb hydrogen, expanding and releasing heat until saturation. The internal pressure of the canister remains at 8 Bar at ambient temperatures of 20C-25C. Once the canister valve is opened and pressure is reduced, hydrogen will be continuously released from the alloy which will absorb heat. If the heat absorption rate decreases, so will the hydrogen release rate.
The canister enclosure materials are made of an aluminum alloy which has excellent heat conductivity properties that can facilitate heat conduction of the alloy during gas absorption and release processes. Gas absorption efficiency of the alloy can be significantly impacted by oxidization due to humidity, therefore dry hydrogen gas with a purity of no less than 99.99% is required for use.
