Abstract The global shift toward a sustainable and eco‐friendly energy landscape necessitates the adoption of long‐term, high‐capacity storage solutions. This research introduces an inventive concept involving movement granular materials from lower elevation to higher point within natural terrains such as mountains or excavated mining sites. Electrical is employed charge electric batteries that elevate material, thereby storing potential energy. Subsequently, this material transported down during electricity generation phase, regenerative braking mechanism converts gravitational replenish vehicle's battery. stored these vehicles then dispatched peak demand periods utilized by for other freight transportation purposes. Our findings demonstrate power cost 1200 USD/kW, expense spanning 1 10 USD/kWh, levelized ranging 35 200 USD/MWh, annual approximately 5.4 PWh. Electric vehicle gravity showcases its capability bolster development offering seasonal multi‐year services.
