Summary: Calcium looping (CaL) process offers a possible solution for next generation Concentrated Solar Power (CSP) plants. However, the conventional CaL-CSP system has limited solar absorption capability due to the white nature of CaCO3. This study introduces dark Ca2MnO4 derived from natural manganocalcite to enhance solar absorption and anti-sintering ability of CaO. The presence of Ca2MnO4 stabilizes the materials' energy storage density and ensures high and stable energy storage performance over prolonged operation cycles.

Summary: With the increase in population and development of technology, the demand for energy has also risen. However, due to the limitedness of energy resources, new research and inventions are necessary to ensure continuous and efficient consumption of these resources. Solar energy, being an unlimited, clean, and abundant energy source, holds great potential in meeting energy demand. However, the usage of solar energy is subject to seasonal variations. Therefore, storage and conversion of solar energy become crucial to maximize its utilization. The application of nanomaterials and phase change materials play significant roles in improving the storage and conversion efficiency of solar thermal energy.
