Abstract
There is provided a system for energy storage comprising: a fluidized bed apparatus with an energy storage material, wherein the energy storage material is provided in volumes coated with an outer layer of solid particles of a different material, wherein the volumes have a largest size in the interval 1-1000 μm and wherein the solid particles (5) have a largest size in the interval 1-500 nm. Advantages of the system include that structural changes in the energy storage material over time are minimized so that the energy storage material can be used over many cycles without any noticeable impairment. The heat transfer to and from the energy storage material is improved. The system can further be used for CO2 capture.
