[0002] As global attention to climate change deepens, the installed capacity of renewable energy such as wind and solar energy has increased rapidly. However, these energy sources are intermittent and unstable, and efficient energy storage systems are needed to balance supply and demand and ensure the stable operation of the power grid.

Hydrothermal flow energy storage, as a zero-carbon emission energy storage technology, meets the requirements of sustainable development and helps to build a greener and low-carbon energy system. Modern power grids require higher flexibility and reliability to adapt to rapidly changing load demands and distributed energy access. Hydrothermal flow energy storage power stations can provide long-term, large-capacity energy storage capabilities, enhance the peak-shaving, frequency regulation and backup power supply functions of the power grid, and improve the stability and resilience of the overall system.
