Light Weight High Entropy Alloys for Safe and Sustainable Energy Storage - HESSENSE

Project summary

The utilization of light-weight materials for hydrogen storage are imperative in the green transition and to ensure safety, energy-efficiency, cost-effectiveness, and suitability in storing energy from intermittent renewable sources like wind and solar. HESSENSE aims to produce light-weight High Entropy Alloys (HEAs) that will operate as hydrogen-storage materials at near-ambient conditions with reversible gravimetric capacity above 2.5 wt.%. The feasibility of the concept will ultimately be demonstrated by the construction of a H2-storage prototype tank, with materials produced by HESSENSE. The aimed performance of the HEAs from HESSENSE will make then attractive for stationary energy storage and the heavy-duty transport sector. HESSENSE thus address EU’s commitment to reach carbon neutrality by 2050 by facilitating the introduction of hydrogen in several key areas and hard-to-abate sectors such as maritime sector, heavy-duty transport, and their related infrastructure.
