the power plant continuously generates power all day long, if the generated power is not used, the energy used for power generation is wasted, the power generation capacity of a power plant is usually fixed and is not easy to change, but the peak power utilization is usually in the daytime, the power is often insufficient in the daytime, the power utilization is in the valley at night, the power which cannot be used is wasted, the electric energy which cannot be used at night is stored for being used in the daytime, so-called 'peak clipping and valley filling', the peak clipping and valley filling are effective ways for adjusting the power load, reducing the peak valley difference of the power grid load and enabling the power generation and the power utilization to tend to be balanced;
compared with electricity storage, heat storage has the advantages of low cost, long service life, large capacity, environmental protection, no pollution and the like, and the heat energy storage has the cost advantage more than that of battery energy storage in terms of the current technical level, and the heat energy accounts for about 70 percent in an energy utilization terminal, so that the heat energy is utilized everywhere whether in resident life, agriculture, industry and national defense;
when the heat storage industry is mentioned, most people have the impressions of 'phase change', 'molten salt', 'photo-thermal power generation' and the like, but the difference between the heat storage industry and the electricity storage industry is large and is manifold, wherein the key point is that no representative concept of a condensation heat storage industry chain exists, no concept exists, the heat storage industry has no rules or no beginning to do after doing things, and the heat storage industry is difficult to have strength, so that the concept of 'a heat storage pool' is created;
several essential indicators of heat storage technology are: material properties, heat transfer, system analysis, cycle stability, process control, and the like; the key requirements are mainly high heat storage density, quick response, no corrosion, no pollution, low cost and the like, and in the future, the following development trends exist:
1. the development of a high-efficiency low-price heat storage system is the direction of '0 carbon' heat supply in the future;
2. although the phase-change heat storage has high heat storage density and is beneficial to the compactness and miniaturization of equipment, some properties of the material need to be further researched, and the composite heat storage material can effectively balance the advantages and the disadvantages of the properties, so that the development of the high-performance composite structure heat storage material has important significance;
3. the chemical heat storage temperature range is wide, the heat storage density is large, but the process is complex and the technical maturity is low, and researches on the aspects of enhancing the reaction rate, well matching the heat transfer performance and the like are needed;
4. the advantages of phase change heat storage and chemical heat storage are obvious, and the two modes are key directions for future research;
5. the heat storage device (unit) is not simply a heat storage product in the traditional sense, but is often a complex system, and further research on system integration and optimization of the heat storage device (unit) is needed, and complex dynamics, system dynamic simulation and optimization, dynamic control of the complex system and the like are needed.
