Performance of Hydrogen Storage Type High Temeprature Chemical Heat Pump Element

Abstract

JAERI has been developing a hydrogen storage type high temperature chemical heat pump, which can amplify thermal energy of the temperautre 373K to 1273K as well as store mass hydrogen energy. To testify the concept of this type of heat pump, we constracted heat pump element test facilities and has been testing its performance.

The present paper reports the recent tests results of the facilities, including R&D on metal-hydride materials
