Gas storage refers to the process of holding natural gas in underground facilities or above-ground tanks to ensure a steady supply during periods of high demand. This is crucial for balancing the supply and demand of natural gas, especially during extreme weather conditions when consumption spikes. There are various methods of gas storage, including depleted gas reservoirs, aquifers, and salt caverns. These facilities allow for the safe and efficient storage of gas, which can be injected into the pipeline system when needed, helping to stabilize prices and ensure energy reliability for consumers and businesses.
