TiMn2-Based Intermetallic Alloys for Hydrogen Accumulation: Problems and Prospects

Abstract

The main advantages of hydrogen as an energy carrier in comparison with currently used hydrocarbons are determined. By comparing the advantages and disadvantages of available methods of hydrogen storage, it was proved that storage of it in a bound state (hydrides) provides the largest amount of stored hydrogen per unit weight of the container and is the safest method. As shown, the alloys based on AB2-type intermetallics are the most promising materials for the safe storage and transportation of hydrogen in the bound state.
