Core Viewpoint - The article highlights the rapid growth and technological advancements in China's new energy storage sector, particularly focusing on compressed air energy storage (CAES) as a promising long-duration storage solution, with expectations of significant capacity increases by 2025 [1][5]. Group 1: New Energy Storage Capacity - By mid-2025, China's new energy storage capacity is projected to reach approximately 95 million kilowatts, representing nearly a 30-fold increase over five years [1]. - The National Energy Administration emphasizes the importance of new energy storage in ensuring power supply during peak summer demand [1]. Group 2: Compressed Air Energy Storage (CAES) - CAES technology utilizes surplus or low-cost electricity to compress air, storing it under high pressure for later use during peak demand periods, facilitating a "power-energy-power" conversion process [3]. - The recent successful verification of the world's highest pressure CAES underground cavern storage technology in Changsha marks a significant milestone in China's CAES development [3][6]. Group 3: Market Growth and Investment - The CAES sector is experiencing a surge in project bidding, with 14 projects initiated from January to May 2024, totaling 4.1 GW/18.7 GWh, a 33.3% increase compared to the same period in 2023 [9]. - The cumulative market space for CAES core equipment is expected to reach 18.5 billion yuan by 2025 and potentially surge to 85.4 billion yuan by 2030, driven by policy support and capital investment [9]. Group 4: Technological Advancements - CAES technology is diversifying, with various methods being explored, including traditional, advanced adiabatic, isothermal, underwater, liquid, and supercritical CAES [5]. - The industry is focused on overcoming efficiency and cost challenges by optimizing thermal management systems and insulation materials [8]. Group 5: Commercialization Efforts - Since the inclusion of new energy storage in government work reports in 2024, the CAES industry has seen significant capacity and scale improvements [8]. - The first non-combustion CAES power station successfully participated in peak summer demand management, showcasing the technology's operational capabilities [10].
