Underground gas storage (UGS)
Underground gas storage (UGS) involves storing natural gas beneath the Earth's surface, typically in depleted oil and gas fields, salt caverns, or deep aquifers. These geological formations can securely hold large volumes of gas, allowing for efficient management of supply and demand. During periods of low demand, excess natural gas is injected into storage sites; during high demand, the gas is withdrawn for distribution. UGS helps ensure energy stability, balancing seasonal fluctuations and emergency needs. It is a safe, cost-effective method that enhances the reliability and flexibility of the natural gas supply chain.
