“…4 At present, the inert carriers with good effect mainly include MgO, MgAl 2 O 4 , ZnO, Ca 12 Al 14 O 33 , SiO 2 , Ca 2 MnO 4 , CaZrO 3 , CuO, CoO, Y 2 O 3 , and CaTiO 3 . [12][13][14][15][16][17][18] To improve the recycling efficiency of calcium-based materials, Kasper et al added ZrO 2 (40%), and the CO 2 capacity was 35.5% after 50 cycles, but a lot of energy storage density was lost. 19 Teng et al improved the spectral absorption by doping with multiple inert carriers (Fe-Mn), and the energy storage density was 1057 kJ kg À1 after 15 cycles.…”

Concentrated solar power (CSP) integrated with calcium looping (CaL) technology has garnered significant interest as a solution to mitigate the issue of intermittency in solar power production. However, the deactivation of CaO‐based materials during cycling limits the application of CaL technology on a large scale. Herein, the dynamic characteristics of the CSP‐CaL system indirectly integrated with the s–CO2 Brayton cycle using CaO–ZnO–Na2SO4 composites are studied. Energy analysis shows that the energy storage density varies from 1328.13 to 1232.03 J g−1, and its average value increases by 32.0%. Round‐trip efficiency of the system varies from 40.0% to 39.5%, and its average value increases by 22.6%. Exergy analysis shows that the co‐doping of ZnO and Na2SO4 into CaO enhances the exergy efficiency of the calciner and the heat exchange network, but reduces the exergy efficiency of the carbonator. Exergy round‐trip efficiency of the CSP‐CaL system has slightly decreased from 44.0% to 43.4%, with an average increase of 22.8%. Techno‐economic analysis shows that the levelized cost of electricity for different sizes of CSP‐CaL systems using CaO–ZnO–Na2SO4 ranges from 176.44 to 153.70 $ MWh−1. Therefore, the CaO–ZnO–Na2SO4 composite shows promising prospects for application in solar thermal power generation.

With the global ambition of moving towards carbon neutrality, this sets to increase significantly with most of the energy sources from renewables. As a result, cost-effective and resource efficient energy conversion and storage will have a great role to play in energy decarbonization. This review focuses on the most recent developments of one of the most promising energy conversion and storage technologies – the calcium-looping. It includes the basics and barriers of calcium-looping beyond CO2 capture and storage (CCS) and technological solutions to address the associated challenges from material to system. Specifically, this paper discusses the flexibility of calcium-looping in the context of CO2 capture, combined with the use of H2-rich fuel gas conversion and thermochemical heat storage. To take advantage of calcium-looping based energy integrated utilization of CCS (EIUCCS) in carbon neutral power generation, multiple-scale process innovations will be required, starting from the material level and extending to the system level.
