The goal of the HyCARE project is to store renewable energy using hydrogen as energy carrier by means of a metal hydride (MH), coupling a phase change material (PCM) for the heat management. The feasibility of the concept has been investigated thanks to the realization of a prototype including a MH-tank and a PCM module storing about 0.5 kg of H2. The innovation of the use of PCM in the heat management of MH system is linked to the reduction of external heat intake, and during the tests the optimal conditions of hydrogen flow, thermal fluid flow, starting temperature have been evaluated, in order to minimize the external power contribution. It was highlighted that, in the optimal conditions, the PCM was able to collect and supply the heat generated/required by the MH storage system, with the external power source contributing only to compensate the heat losses.

Abstract
The goal of the HyCARE project is to store renewable energy using hydrogen as energy carrier by means of a metal hydride (MH), coupling a phase change material (PCM) for the heat management. The feasibility of the concept has been investigated thanks to the realization of a prototype including a MH-tank and a PCM module storing about 0.5 kg of H2. The innovation of the use of PCM in the heat management of MH system is linked to the reduction of external heat intake, and during the tests the optimal conditions of hydrogen flow, thermal fluid flow, starting temperature have been evaluated, in order to minimize the external power contribution. It was highlighted that, in the optimal conditions, the PCM was able to collect and supply the heat generated/required by the MH storage system, with the external power source contributing only to compensate the heat losses.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
