Metal Hydride Storage Canisters
Technology
The Heliocentris metal hydride storages are equipped with a low temperature AB2 metal alloy on a TiMg base:
– absorb the hydrogen in the alloy lattice after adsorption at the surface
– can store hydrogen at high volume- and low weight density (ideal for stationary application)
– has a low plateau pressures at about room temperature
– has a low thermal conductivity
The canister is designed as a passive surface cooled system. Heat ducting can be applied by the user with air ventilation or water cooling.
Temperature Handling
The nominal parameters of the canister are defined for a canister surface temperature of 20°C. The absorption/ desorption performance of the storage can be sensitively influenced by thermalizing the canister surface by:
− cooling the storage surface for absorption (filling) by water or air with 5 5 20°C
− heating the storage surface for a continuously desorption by water or air with 20 5 50°C
− usage of the ambient air with passive or active ventilation
Integration, Usage and Safety
An integrated quick coupling allows an easy and safe connection to an individual hydrogen source. The storage is equipped with a pressure and temperature relief valve to avoid dangerous conditions.
