AI Technical Summary

Problems solved by technology

[0004] In the field of solar energy, molten salt is used to store heat. Although molten salt can achieve high temperature storage, it needs heat energy to heat it because it needs to be transformed from solid to liquid. At the same time, there are problems with the toxicity, economy, and safety of molten salt. , so the use of molten salt heat storage is limited

[0005] In the field of solar energy, air or other gases are also used for heat storage, but its thermal fusion is small, and large-scale thermal energy storage cannot be realized

[0006] The energy storage power station uses electric energy for storage, especially the electric energy composed of wind power and photovoltaic, because it cannot be stored, it has to be discarded in large quantities, causing a lot of waste
