Description
It is a constant research interest in finding reliable solutions for the long term storage of hydrogen isotopes that integrates both the safety matters and its easy recovery. Thus, various methods have been investigated so far, namely gaseous storage in high pressure gas cylinders, liquid storage in cryogenic tanks or under solid state form. Considering as option the storage on solid substrate, for which a myriad of materials were investigated over time, this work focuses on the storage bed activation and absorption/desorption characteristics of a ZrCo bed alloy. Hydrogen isotopes (Protium and Deuterium) where selected as the working gases.
The activation was performed at 500 ºC under vacuum conditions, hydrogenation at maximum 100 ºC under a pressure of 1bar, and the dehydrogenation at temperatures up to 300 ºC. Defined by qualities like easy activation, low equilibrium working pressure, high adsorption rate at low temperature and use of moderate temperature for hydrogen gas recovery, ZrCo represent one of the strongest candidate materials, beside uranium and titanium, for the design and construction of dedicated getter beds necessary to capture and transfer hydrogen isotopes
