CC-BY 4.0 . Long-term storage capability is often claimed as one of the distinct advantages of the calcium looping process as a potential thermochemical energy storage system for integration into solar power plants. However, the influence of storage conditions on the looping performance has seldom been evaluated experimentally.
The calcium gluconate ( (Ca (C 6 H 11 O 7) 2)) was used as the precursor while fabricating the porous CaCO 3, and the Mn–Fe oxides were doped into CaCO 3 through two different doping processes. The experimental results indicate that the proposed material obtains the solar absorptance of ∼90%.
