“熔盐储能+煤电”千亿元级市场待激活

Core Viewpoint - The article discusses the challenges and opportunities of "molten salt energy storage" in the context of its integration with coal power plants, highlighting the need for policy guidance, technological innovation, and industry collaboration to overcome existing barriers [1][3][8]. Group 1: Project Overview - The largest domestic molten salt energy storage project combined with coal power, a 350 MW demonstration project at Anhui Guoneng Suzhou Power Plant, has been launched, showcasing significant market potential [3][5]. - The project utilizes two large molten salt tanks, one for high-temperature and one for low-temperature storage, with a total heat storage capacity of 1000 MWh [5][6]. - The project allows for a reduction in minimum technical output from 50% to 30% and increases maximum load from 80% to 100%, demonstrating enhanced flexibility in power generation [5][7]. Group 2: Market Potential - The combination of "molten salt energy storage + coal power" is expected to activate a market potential worth billions, with further applications in high-heat industries like steel and chemicals potentially expanding the market to hundreds of billions [3][5][7]. - If 30% of the existing coal power capacity of approximately 1.1 billion kW were to adopt molten salt energy storage systems, it could lead to significant market investments [7]. Group 3: Challenges in Scaling - High customization requirements for different coal power plants pose a significant challenge, necessitating tailored designs for each system [9][10]. - The initial investment for molten salt energy storage projects is high, with the Suzhou project costing around 340 million yuan, which may deter some power plants from investing [9][10]. - The lack of national standards for molten salt tank design and safety regulations creates additional risks and uncertainties for the industry [9][10]. Group 4: Recommendations for Development - Industry experts suggest that policy support is crucial, including integrating molten salt energy storage into new power system planning and establishing clear compensation mechanisms for peak shaving [11][12]. - Technological innovations aimed at reducing costs and improving efficiency are essential for the widespread adoption of molten salt energy storage [11][12]. - Establishing national standards for design, construction, and acceptance of molten salt storage tanks is necessary to ensure safety and efficiency [11][12].
