Abstract  Heat storage and energy storage are key technical issues in the development of solar energy system. Several solar energy storage technologies， including short-term heat storage， seasonal heat storage， sensible heat storage， chemical reaction heat storage， and phase change heat storage， are introduced to address the scarcity， intermittency， and unreliability of solar energy. The paper analyzes the research status of heat storage technologies at home and abroad. Analysis shows that the thermal conductivity of phase change materials and the application cost of phase change heat storage technology are the main directions for the corresponding researches in the future.
