Revolutionizing Energy Storage in China
A groundbreaking achievement in energy storage has just occurred in Yingcheng City, located in central China’s Hubei Province. The newly inaugurated compressed air energy storage (CAES) power station has successfully connected to the grid, reaching an impressive full capacity of 300 MW. This facility stands as the largest operational CAES project globally.
The innovative “Energy Storage No. 1” project employs two vast underground salt caverns originally formed from an abandoned salt mine. These caverns plunge deep into the earth, reaching depths of up to 600 meters, and provide a remarkable gas storage capacity nearing 700,000 cubic meters. This ambitious venture boasts a single unit power output of up to 300 MW, with a robust storage capability of 1,500 MWh.
The system is designed to operate efficiently, achieving about 70% conversion efficiency. It has the ability to store energy for up to eight hours and can release it over five hours on a daily basis. As a result, this state-of-the-art power station is poised to generate around 500 GWh of electricity each year, significantly contributing to the energy landscape.
With this successful launch, China solidifies its role as a leader in innovative energy solutions, paving the way for a sustainable future.
