Abstract
This paper presents the development and implementation of a hybrid energy storage system combining a sand battery and a gravity battery. The system includes an automatic switching mechanism based on the power availability from each unit. The sand battery stores thermal energy using silica, while the gravity battery utilizes gravitational potential energy with mass elevation. A microcontroller-based monitoring system tracks real-time energy data and activates the battery that generates higher output at any given time. This approach enhances energy reliability and efficiency in renewable-based systems and offers a sustainable storage alternative.
