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.
