Abstract
A system for thermochemical energy storage using earth-abundant materials triggered by the addition of water is provided. The system comprises reactants including CaO, P2O5, Fe, and KNO3 among others in a matrix. Exothermic reaction is initiated by addition of water. Thermal generation over time may be adjusted by selection of matrix and by selective addition of additional reactants such as alternative oxidants or secondary fuel sources.
Claims29
A thermochemical energy storage system, comprising:
- a first reactant;
- a second reactant;
- and
- a matrix,
- wherein the first reactant and the second reactant react exothermically in the presence of water thereby producing thermochemical energy.
