文摘
- •
The cascaded hybrid sensible/thermochemical (TCS) heat storage concept was tested.
- •
Co3O4- and Mn2O3–coated cordierite honeycomb and foam cascades were employed.
- •
TCS capability of Co3O4 manifested as heat storage/release at constant temperature.
- •
Additive effect of thermochemical on sensible storage proved for Co3O4/CoO pair.
- •
CoO and Mn3O4 oxidations in complementary temperature ranges during cycling.
