Described as the world's first 10 MW-class multi-source heat-storage CAES demonstration plant.
The project is led by the China Three Gorges Science and Technology Research Institute. Xi'an Thermal Power Research Institute carried out the performance tests, and CIMC ENRIC was one of the commissioning partners alongside the equipment makers and design institute.
No salt cavern needed. Standard vessels store the air above ground.
CIMC ENRIC delivered the plant's high-pressure above-ground air storage system: system design, code-compliant pressure vessels, installation, staff training and after-sales support. The reservoir uses standard high-pressure gas storage units developed jointly for the project. The compressors, expansion turbine and thermal systems were supplied by other partners.
Have a high-pressure gas storage need? Tell us your scenario.
Tell us how and where the gas will be stored and used. We'll work out a suitable storage route with you. Typical application areas:
Bring your MW, MWh, discharge hours and land. We'll start with the storage route.
Batteries, compressed air and CO₂ storage each fit different durations. CIMC ENRIC helps you compare the options, from pressure vessels to complete systems.
