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].
