About

The lined rock cavern (LRC) concept is a cutting-edge solution for large-scale underground storage of pressurized gases. The figure below (based on Damasceno, 2022) shows a typical setup, with access tunnels and lining components. In an LRC, the steel lining ensures gas-tightness, while the surrounding rock mass provides confinement for the internal pressure. The LRC excels compared to other solutions due to its geological flexibility, enabling energy storage placement close to demand centers.
