The HyCARE project aims at developing a hydrogen storage tank with use of a solid-state hydrogen carrier in large scale. The tank will be based on an innovative concept, linking hydrogen and heat storage to improve energy efficiency and to reduce the footprint of the whole system. It will be connected to a 20 kW Proton Exchange Membrane (PEM) electrolyser as hydrogen provider and a 10 kW PEM fuel cell as hydrogen user. The tank will be installed in the site of ENGIE Lab CRIGEN, a research and operational expertise centre dedicated to gas, new energy sources and emerging technologies.
The HyCARE hydrogen storage tank will be based on solid-state carrier, using metal hydride that will be part of a renewable energy plant exploiting the use of H2 as energy vector for stationary energy storage.
The energy produced by renewable sources is used to produce H2 from water through an electrolyser. The gas is then stored in the HyCARE tank using a carrier. A heat storage system is planned to collect heat produced by the renewable plant, the electrolyser and from the Metal Hydrides, during H2absorption. The collected heat used during the desorption event to release hydrogen from the MH. Finally, the released H2 supplies a fuel cell (FC) producing electricity.
