Grid-Scale Mechanical Battery

The global shift to renewable energy creates a massive demand for grid-scale storage to stabilize power grids. Current lithium-ion batteries, while dominant, face challenges with supply chain volatility, geopolitical risks for critical minerals like lithium and cobalt, and long-term environmental concerns regarding mining and recycling at a massive scale.

A mechanical energy storage system offers an alternative. It uses electricity to run compressors and turbines, storing potential energy in a physical state, such as compressed gas. This approach avoids rare minerals, potentially offers a longer system lifespan, and may scale more cost-effectively for the long-duration storage needed to fully enable a renewable-powered grid.
