A231 Studies on metal hydride tank in totalized hydrogen energy utilization system for buildings : Improvement of availability of reaction heat

Abstract

We have studied on metal hydride tanks for load leveling of commercial buildings. The storage tank with 50 kg AB5 type metal hydride alloy was assembled to investigate the hydrogen absorbing/desorbing process, which is exothermic/endothermic process. We have a plan to utilize hot heat and cold heat of each process for air conditioning that could be expected to improve the system efficiency. In order to get high availability of reaction heat, optimization of operating method is required. For this reason, evaluation of operating method is carried out by experiment and numerical simulation.
