On the morning of March 12, 2026, the groundbreaking ceremony for the PV–molten salt energy storage demonstration project at the combined heat and power (CHP) plant of Dushanzi Petrochemical Company was successfully held, marking the official start of construction.
The Phase II scope of the project includes the construction of one molten salt energy storage system with an effective thermal storage capacity of 480 MWht. The system utilizes green electricity to charge the molten salt via electric heaters, with a total installed electric heating capacity of 150 MW. The stored thermal energy is then converted into steam through a molten salt heat exchange system, serving as an effective supplement to the main steam network of Unit 2 at the CHP plant.
The project is expected to annually absorb approximately 281 GWh of renewable electricity, produce 416,000 tonnes of high-pressure steam, reduce standard coal consumption by 42,900 tonnes per year, and cut carbon dioxide emissions by 111,600 tonnes per year.
