Dolomite-derived composites doped with binary ions for direct solar thermal conversion and stabilized thermochemical energy storage

Long-stable solar energy capture and storage via negative thermal expansion regulated calcium-based particles

“…20 Sun et al also used binary inert carrier doping to modify dolomite, making its spectral absorption rate reach 73.22% and energy density 770 kJ kg −1 after 30 cycles. 21 Our previous work also screened and proved these inert carriers. It is believed that doping with Fe element can form black compounds with calcium oxide at high temperatures, which can improve the spectral absorption rate of the particles due to the extremely poor light absorption ability of pure calcium carbonate.…”

Review on the modifications of natural and industrial waste CaO based sorbent of calcium looping with enhanced CO2 capture capacity

“…Furthermore, dolomite modified with PrA has a lower initial CO 2 capture capacity than undoped dolomite but exhibits a stable CO 2 capture capacity [ 137 ]. In conclusion, dolomite acid modification improves the sorbent's stability but shows no improvement in terms of initial capture capacity.…”

“…Bai et al (2022) [ 137 ] doped the dolomite with Fe1–Mn0.5 but it exhibited a lower initial CO 2 capture capacity but better stability than undoped dolomite. This binary doping of Fe and Mn ions is CaO-based composite.…”

Research on Optimization Design Based on Heliostat Field

“…The heliostat field planning of this study is based on the 6282 mirror field [9] , and the distribution of heliostats in this mirror field is shown in Fig 4. Among them, the positive directions of the x-axis and z-axis point to due east and south, respectively, while the y-axis points to the sky.…”
