Thermochemical energy storage (TES) is a promising technology which provides durable storage and high storage density. In this work, the MgO-CO2 working pair was adapted for TES by the oxide modification with a salt. A brief screening of various salts showed that a lithium acetate (LiOAc) additive considerably promotes the MgO carbonation. The kinetics of the process was studied at T = 280oC-340oC and P(CO2) = 1-10 bar. Decomposition of LiOAc/MgCO3 was studied by differential scanning calorimetry. The transitions of MgO to MgCO3 and backwards were studied by X-ray diffraction analysis in situ
