The HyCARE hydrogen storage tank will be based on a 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 solid-state carrier. A heat storage system based on phase change materials collects the heat produced by the renewable plant, the electrolyser and from the metal hydrides, during H2 absorption.
The collected heat is used for the desorption from the metal hydride to release hydrogen. Finally, the released H2 supplies a fuel cell (FC), producing electricity.
