China is advancing in the expansion of new energy storage capacity, a key initiative aimed at accelerating the adoption of renewable energy and ensuring a reliable power supply.
The world's largest renewable power producer is set to exceed 50 GW of new energy storage capacity by 2025, according to a recently published report.
In 2022, China's installed capacity of renewable energy surged to 760 GW, representing a 20% increase from a year earlier, as stated by Dai Jianfeng, an engineer at the China Electric Power Planning and Engineering Institute (CEPPEI), a consultancy affiliated with China Energy Engineering Group, a state-owned enterprise.
Given the increasing importance of safe and reliable power system operation, new energy storage is poised to become a vital technology supporting the construction of the future power system, Dai emphasized during a forum in Beijing.
New energy storage encompasses electricity storage methods that utilize emerging technologies like compressed air, flywheels, and electrochemical processes, in contrast to traditional pumped hydro storage.
Compared to pumped storage, which employs dams to store water and generate electricity as needed, new energy storage offers more flexibility in site selection and boasts advantages such as shorter construction periods, rapid and flexible response capabilities, and diverse functions. It plays a critical role in renewable power systems by ensuring a stable power supply from intermittent and variable sources like wind and solar.
By the end of 2022, China already possessed a total new energy storage capacity of 8.7 GW, marking a remarkable increase of over 110% compared to the previous year, as reported by Liu Yafang from the National Energy Administration (NEA) at the forum.
China is determined to develop a new power system that features a higher share of renewable energy resources like wind and solar. This goal aligns with the country's commitment to peak carbon emissions by the end of the 2030s and achieve net-zero emissions by 2060.
The Chinese government has also established targets of at least 1,200 GW of solar and wind generation capacity by 2030, along with a minimum 80% contribution from non-fossil fuel sources to the total energy mix by 2060.
