Research on the Power Generation Efficiency of Zero-Carbon Port Framework-Based Gravitational Energy Storage Systems

Based on containers as heavy objects, a framework-based gravitational energy storage system is designed, where the container is lifted to a certain height to store gravitational potential energy, which is then released to drive a generator for power generation. The system utilizes existing port infrastructure, reducing the manufacturing cost of heavy blocks and offering good environmental adaptability. The results show that framework-based gravitational energy storage systems have high feasibility in port energy supply, providing stable power output and improving energy efficiency. Through optimization analysis of storage efficiency, power generation efficiency, and other parameters, this study provides theoretical and technical support for achieving sustainable green development in ports. This paper firstly describes the design and operating principles of the system, followed by a detailed indoor test analysis. Subsequently, the test results are specifically analyzed. Finally, practical implications and future development directions are discussed.
