Abstract

Thermochemical energy storage (TCES) is a preferred approach for long duration thermal energy storage due to its high energy storage density and low heat loss. The reactants used in gas-solid and gas-gas medium and high temperature TCES systems were summarized

the characteristics of various thermochemical storage materials were reviewed

and the research challenges including reactant modification

development of novel materials

and catalyst optimization were discussed in depth. The performances of fixed bed

moving bed

and fluidized bed thermochemical reactors were comparatively analyzed

and suitable reactor types were proposed for different reaction systems. Open and closed thermochemical reaction systems were comprehensively analyzed

with their performance under variable operating conditions and the advantages and disadvantages in practical applications evaluated. An economic analysis of TCES systems was conducted to assess their commercialization potential

and the costs at different technology readiness levels were estimated.
