Core Insights - The article discusses the successful implementation of a molten salt energy storage project by the State Energy Group's Anhui Company, which allows for flexible peak regulation of coal-fired power plants while providing stable heating to nearby industrial parks [1][2]. Group 1: Project Overview - The molten salt energy storage project enables coal-fired power plants to store excess energy during low demand periods and release it during peak demand, thus overcoming the traditional limitations of coal power generation [1]. - The project utilizes high-temperature molten salt, which can store 3,600 GJ of thermal energy, allowing for efficient energy management [2]. Group 2: Technical Innovations - The project involved significant breakthroughs in core technologies, with the entire process from theoretical research to practical implementation being developed independently by the company [2]. - The molten salt storage system operates on a "store heat during idle times, supply heat during busy times" mechanism, enhancing the flexibility of coal power plants [2]. Group 3: Impact and Benefits - Once operational, the project is expected to increase the capacity for renewable energy consumption by 128 million kWh annually and enhance heating capacity by 2.2 million tons, representing a 73% increase over previous maximum heating capabilities [2]. - The project will meet the heating needs of over 40 local enterprises, demonstrating its significant contribution to regional energy stability [2].

清晨，在国家能源集团安徽公司宿州电厂，熔盐储能项目工作人员紧盯负荷曲线，控制机组在稳定发电 的同时，将富余的能量"存起来"。大屏上显示的实时数据不断刷新，一股股高温蒸汽悄然流入巨型储 罐。用电高峰期，被"存起来"的热能又会及时释放，替代机组为附近的工业园区提供稳定热能。 这是由国家能源集团新能源技术研究院自主研发、国家能源集团安徽公司宿州电厂建设的"煤电+熔 盐"储能项目。该项目打破了传统煤电"以热定电"限制，让煤电机组解锁灵活调峰"超能力"。 "随着新能源占比不断提高、电力系统调峰压力持续加大，煤电成为非常重要的灵活性调峰电源。煤电 机组往往还承担着为工厂供热的任务，这就导致了一个痛点——想灵活调峰就得减供热，想保供热就没 法深度参与电网调节。"国家能源集团新能源技术研究院储能技术研究中心负责人金翼说。 破解两难的关键，正是此次投产的巨型"储热宝"——熔盐储热装置。 金翼介绍，熔融态液体盐具有高沸点、低黏度、低蒸汽压力和高体积热的优势。熔盐储热装置依托熔盐 的这种特性，可储存3600吉焦热量。其工作机制围绕"闲时储热、忙时供热"展开：在电网电力富余或机 组处于低负荷"闲暇"状态时，装置会通过机组抽汽蓄热，将 ...
