Demonstration of the co-generation of heat and hydrogen by high-temperature oxidation of aluminum in steam
Résumé
The development of a circular economy based on the storage of decarbonized energy is essential. A potential solution involves storing surplus (intermittent) green energy by converting metal oxides into metal powders. This is in particular effective in regions with preferred wind conditions and extreme exposure to sunlight. These powders, which can be transported safely, can then be used to release the stored energy as required in other parts of the world. An experimental method involves the oxidation of metal particles in steam to simultaneously generate heat and hydrogen. The first proof of this concept, which shows the full conversion of steam to hydrogen, is presented in this contribution.
