Designing an AB<sub>2</sub>-Type Alloy (TiZr-CrMnMo) for the Hybrid Hydrogen Storage Concept

The hybrid hydrogen storage method consists of the combination of both solid-state metal hydrides and gas hydrogen storage. This method is regarded as a promising trade-off solution between the already developed high-pressure storage reservoir, utilized in the automobile industry, and solid-state st...
