Research status and prospects of solid electric heat storage technology

Abstract

As a key component of energy storage technology， solid electric heat storage technology is adopted to convert valley electricity and various fluctuating electricity energy such as wind power and solar power into heat. The technology excels in environmental protection， efficiency， energy saving and safety and exhibits great potentials in regional heating renovation， deep peak regulating of the power grid and heat supply for industrial production. To this end， the principle of solid electric heat storage technology is introduced， and the research status and progress of solid heat storage materials and device structure are summarized. Moreover， bottleneck and key direction of the development of solid electric heat storage technology is discussed. Finally， the application status of the technology in different fields at home and abroad is sorted out and analyzed economically to provide ideas for promoting the development of the technology.
