Recently, China Energy Construction's "Energy Storage No.1" project - the Tai'an 350MW Compressed Air Energy Storage Innovation Demonstration Plant (the world's largest single-unit compressed air energy storage power station under construction) - has been widely reported by mainstream media including the State Council SASAC official website, People's Daily, Xinhua News Agency, and CCTV.com.
People's Daily's article Exploring the World's Largest Single-Unit Compressed Air Energy Storage Power Station Under Construction: How Air Generates Electricity explains:
Air, though invisible, stores energy by converting electricity into pressurized air and thermal energy during charging. During discharge, high-pressure air drives turbines to regenerate electricity.
The Shandong Tai'an project innovatively utilizes abandoned underground salt caverns as air reservoirs, while storing compression heat in ground-level thermal storage tanks using hot water and molten salt.
Phase I features a 350MW salt-cavern non-supplementary combustion CAES system, achieving 8-hour charging and 4-hour discharging cycles. With an annual output of 460 million kWh (enough for 200,000+ households), a single charge can power mid-sized cities for 5 hours.
As crucial grid flexibility infrastructure, such storage systems resolve timing mismatches between renewable generation and demand, effectively reducing wind/solar curtailment and boosting clean energy utilization.
Doright collaborates with Harbin Electric Corporation to enhance new energy manufacturing capabilities, providing critical heat exchange equipment for this landmark project. The specially designed heat exchangers ensure safe, durable, and efficient energy transfer during air compression/expansion processes. This milestone demonstrates DORIGHT's technical competence in CAES thermal management systems, marking its official entry into the air energy storage sector.
Moving forward, Doright will continue advancing technological innovation across cutting-edge fields, delivering greater value to global clients while building a diversified development ecosystem.
