Abstract: A novel hybrid energy storage method is proposed in this paper to overcome high temperature levels at the start of the reaction in thermochemical energy storage, which causes this technology to be unsuitable for constant temperature applications. This numerical study shows that the hybrid storage system with thermochemical material and phase change material is a promising method in the field of low temperature thermal energy storage. The melting temperature of the PCM and the flow rate of the heat transfer fluid must be chosen carefully to enhance the performance of the system.

Keywords: hybrid energy storage; HES; thermochemical energy; packed bed reactor.
