Designing High Entropy Alloys for Efficient Hydrogen Storage

Science / Engineering

Brazil boasts a vast potential for generating energy from renewable sources. Hydrogen is deemed the perfect energy vector to fully harness the advantages of these renewable sources. The energy generated by these sources can be converted into hydrogen from water through various electrolysis techniques. One of the most urgent technological hurdles for the deployment of this novel energy system is devising mechanisms to store hydrogen in a safe, efficient, and cost-effective manner. High entropy alloys, a new class of metallic materials composed of multicomponent alloys with a minimum of five principal elements, could offer a solution. Recent studies have demonstrated that the TiVZrNbHf alloy can absorb a significantly higher hydrogen content compared to previously studied metallic hydrides. This research is focused on designing high entropy alloy compositions with optimized properties for hydrogen storage.
