Abstract:

In order to mitigate global warming,achieve "emission peaking and carbon neutrality" and utilize new energy resources efficiently,the power system taking new energy as the main part and power storage industry have to develop in coordination.As one of the key technologies for the joint development,the seasonal underground thermal energy storage,especially Aquifer Thermal Energy Storage(ATES),is difficult to be transformed from theory to engineering cases.Summarizing the methods and principles of underground thermal energy storage,the theoretical research progress of ATES system in numerical simulation and testing are analyzed.Then,the key technologies and bottlenecks in practical engineering cases are deeply analyzed.The evaluation standards for thermal performance,economic and environmental benefit of ATES systems are compared.On this basis,the prospect of the new power system coupled with ATES technology is made,which can provide reference for the following researches.

Key words: underground thermal energy storage, Aquifer Thermal Energy Storage, seasonal, performance evaluation, renewable energy, carbon neutrality, heat supply
