Multicycle activity of natural CaCO3 minerals for thermochemical energy storage in Concentrated Solar Power plants

Thermochemical energy storage in Concentrated Solar Power plants by means of the Calcium-Looping process is a promising novel technology that would allow for a higher share of renewables. A main benefit of this technology is the use of widely available, non-toxic and environmentally friendly calcium...
