新会员 | 浙江同景科技：创新推出恒压压缩空气储能技术

Core Viewpoint - Zhejiang Tongjing Technology Co., Ltd. has officially joined the Zhongguancun Energy Storage Industry Technology Alliance, indicating its commitment to advancing energy storage technology and collaboration within the industry [2]. Company Introduction - Zhejiang Tongjing Technology Co., Ltd. was established in December 2020 and is located in Jiangshan, Zhejiang Province. It specializes in the research, development, and manufacturing of energy storage systems and equipment [4]. - The company is part of the Zhejiang Tongjing New Energy Group, which has evolved into a comprehensive technology innovation group with over 3,000 employees and more than 200 patents since its inception in 1994 [4]. Constant Pressure Compressed Air Energy Storage System - The constant pressure compressed air energy storage system developed by Tongjing achieves a storage efficiency improvement of 6%, reaching 75% efficiency, and maintains a storage chamber utilization rate of over 95% [8][14]. - The system's cost is reduced to below 0.7 yuan/Wh, making it economically viable for medium to long-term energy storage applications [19]. Advantages of Constant Pressure Compressed Air Energy Storage - The system offers high safety and stability, with pressure maintained between 7 to 14 MPa during charging and discharging, reducing maintenance frequency and ensuring long-term stable operation [15]. - It has a lower construction cost due to a 40% reduction in storage space requirements compared to conventional systems, allowing for easier site selection [16]. - The system is adaptable for various applications, including combined heat and power, and can integrate with data centers and thermal power plants [17]. - The economic benefits are significant, particularly for medium to long-term storage, outperforming lithium battery systems in suitable conditions [19]. Pilot Project - The pilot demonstration project in Jiangshan utilizes local geological features for constructing the compressed air storage chamber and has received approval from the provincial energy bureau to commence construction [19].
