Gas storage refers to the process of holding natural gas in underground facilities or above-ground tanks for later use. This is essential for balancing supply and demand, especially during peak usage times, such as winter months when heating needs increase. There are various methods of gas storage, including depleted gas reservoirs, aquifers, and salt caverns. These facilities allow energy companies to ensure a steady supply of gas, helping to stabilize prices and maintain energy security for consumers and businesses alike.
