Abstract
Heat storage technology is one of the key technologies in the field of solar thermal power generation and cogeneration. It uses heat storage materials as the media to store solar thermal energy, industrial waste heat, low-grade waste heat and other kinds of thermal energy, and release it when needed, so as to solve the mismatch between energy supply and demand. This paper introduces the classification and characteristics of heat storage technology, analyzes the research progress of heat storage technology in the fields of solar thermal power generation, heat storage materials and industrial drying, and forecasts the development trend of heat storage technology in the future. The results indicate that heat storage technology is beneficial to improve industrial production efficiency, broaden industrial energy conservation and emission reduction ideas, and has a great application prospect under the continuous improvement of practitioners with innovative spirit.
