HyGES

Project Overview
About
Many African communities lack reliable electricity, while solar and wind power require affordable storage for periods when generation falls. HyGES stores surplus energy by lifting heavy solid weights, then lowers them to generate electricity when needed. Unlike pumped hydropower, it requires no large water supply and can be installed in abandoned mines or other existing structures. Made from widely available materials and designed for a long operating life, the system could provide dependable renewable power while reducing reliance on diesel generators and short-lived batteries.
