Core Viewpoint - The abandoned salt caverns in Huai'an, Jiangsu, are being repurposed into a large-scale "green battery" for compressed air energy storage, supported by a 500 million yuan financing from Hengfeng Bank [1][4]. Group 1: Project Overview - The Huai'an project utilizes unique geological conditions to store compressed air in underground salt caverns, enabling energy storage during low demand and electricity generation during peak demand [2][3]. - The project employs a pioneering "molten salt + pressurized thermal medium water storage" technology, achieving a high energy conversion efficiency of 71%, setting a new record in the domestic compressed air energy storage sector [2][4]. Group 2: Financial Support and Implementation - Hengfeng Bank established a specialized service team to address the project's complex financing needs, completing the loan approval process in just 10 working days [3][4]. - The bank's support is crucial for the project's success, which is the first 300 MW compressed air energy storage project in Jiangsu and a demonstration of domestically produced major technological equipment [4][6]. Group 3: Environmental and Economic Impact - Upon completion, the project will have a total storage capacity of 2,400 MWh and an annual electricity generation of approximately 792 million kWh, benefiting around 600,000 households [4]. - The project is expected to save about 250,000 tons of standard coal and reduce carbon dioxide emissions by 600,000 tons annually, contributing to China's "dual carbon" goals [4][6].

位于张家港的国信沙洲扩建项目500千伏送出工程是国家级规划能源项目，建设人员正新建12.3公里500 千伏电力线路，同时改造多座变电站间隔；在常州的华能金坛盐穴压缩空气储能发电二期项目现场，工 人在盐穴深处有序施工，给电网加装"巨型充电宝"；在镇江，技术人员在扬镇直流二期线路工程江南段 现场忙碌组立铁塔…… 新华财经南京5月3日电 （记者何磊静） 5月2日傍晚，在江苏靖江斜桥镇的国信靖江电厂扩建项目500千 伏送出工程施工现场，重型卡车往来穿梭，塔吊巨臂空中挥舞，不少工人在电力铁塔上紧张有序作业， 橙色的安全帽与夕阳交相辉映。 "这是江苏省'北电南送'重点工程，我们'五一'假期不停工，全力以赴保障重大能源工程稳步推进。"国 网靖江市供电公司发展建设部主任陈玲对记者说，该工程力争今年9月底投运，届时每年输送电量可达 100亿千瓦时，将为推动区域高质量发展提供重要能源支撑。 在轰鸣的机械声中，吊车将一段段塔材精准对接。现场作业人员陈晨说，他们正对电力铁塔进行吊装改 造，为后续开展架线建设做好准备。"预计新增铁塔45基，目前已完成35基铁塔的基础建设。" 这是经济大省江苏重大能源工程"五一"假期不停工的写照。记者从 ...
