According to a 2025 Cleanview report, the country installed a record-breaking 48.2 gigawatts (GW) of utility-scale solar, wind and battery storage capacity—a 47% increase over the previous year.
[pdf] MGES uses natural elevation changes to store and release energy efficiently and sustainably. How it works: Large masses (like railcars) are moved up a mountain during times of excess energy, then released downhill to generate power during periods of high demand.
[pdf] It has developed more than 20 series of photovoltaic inverter products such as grid-connected and energy storage, with a power coverage of 0.7-250kW, fully meeting the needs of household, cargo, industrial and commercial and large power stations, and has built multiple industrial bases such as Suzhou and Anhui, forming a large-scale industrial cluster.
[pdf] Superconducting magnetic energy storage (SMES) has been studied since the 1970s. It involves using large magnet(s) to store and then deliver energy. The amount of energy which can be stored is relatively low.
[pdf] The directions of energy storage engineering include: 1. Development of advanced battery technologies, 2. Integration of renewable energy sources, 3. Enhancement of grid stability, 4. Innovative materials and efficiency improvements.
[pdf] Compressed air energy storage (CAES) is an established and evolving technology for providing large-scale, long-term electricity storage that can aid electrical power systems achieve the goal of decarboni.
