Abstract
This study introduced an experimental gravity energy storage system designed for educational purposes and demonstrations, addressing the increasing demand for efficient renewable energy storage solutions, with a focus on solid gravity energy storage. The study outlined the construction and dynamics of the system. A small prototype served to validate the practical application, while simulations and results showcased the system's efficiency. The physical end-product, including CAD models and images, was presented with details on output power, energy capacity and efficiency. The results show an overall efficiency of 54% at the optimal point of operation. Adjusting the size of the mass resulted in more energy generated while active braking ensures high efficiency is maintained. Enhanced energy conversion could be achieved with advanced control systems, improving the efficiency of electricity capture. The gravity energy storage system's effectiveness compared to traditional battery storage is clear, offering notable advantages in scalability, lifespan, and sustainability.
