填补电网瞬态支撑空白，中国短时高频储能迈向千亿市场

Group 1 - The new power system faces risks of frequency instability due to insufficient transient energy storage capacity as the share of renewable energy installations increases [1][2] - Traditional energy storage technologies struggle with short lifespan, slow response, and narrow operating temperature ranges, necessitating the introduction of power-type energy storage technologies with "instantaneous rigid support" capabilities [1][2] - The lithium-ion capacitor developed by China Green Development can provide significant advantages, including a cycle life of up to 1 million times and a response time in milliseconds, addressing systemic challenges in energy storage [1][2] Group 2 - The Ministry of Industry and Information Technology and other departments have outlined a development plan for new energy storage technologies, emphasizing the need for high-performance supercapacitors and other advanced storage solutions [2] - The lithium capacitor's performance metrics include a power density of 15 kW/kg and an energy density of 16 Wh/kg, which are over three times that of traditional supercapacitors, making it suitable for short-term high-frequency energy storage [2] - The global demand for short-term high-frequency energy storage is expected to grow, with market share projected to increase from 10%-18% to 20%-25% by 2030, indicating a significant market opportunity [3]
