Multi-criteria evaluation of on-board hydrogen storage technologies using the MACBETH approach

摘要

This paper provides some results obtained from the implementation of the MACBETH multi-criteria evaluation approach for the evaluation and comparison of the technical performance of three hydrogen storage technologies: a type IV 70 MPa hydrogen storage system, a cylindrical steel made liquid hydrogen storage system and a solid storage system. The evaluation is carried out considering a 6 kg hydrogen fuel cell vehicle application. Five technical evaluation criteria are taken into account in the analysis: system volume, system mass, refuelling time, hydrogen loss rate and conformability. The outcomes and added-value of this multi-criteria approach are finally discussed.
