Is Carbon Dioxide in Case of Natural Gas Storage a Feasible Cushion Gas?

Demand for natural gas is generally seasonal in nature: more natural gas is required in the winter than in the summer, and therefore prices in the winter are generally higher. Operators of natural gas storage facilities have the opportunity to arbitrage these seasonal price differences. Furthermore, gas buffer volume close at the consumer’s site of the delivery chain makes it possible to optimize gas production and long distance transport. Each storage location has its own physical characteristics (porosity, permeability, retention capability) and economics (site preparation and maintenance costs, deliverability rates, and cycling capability), which govern its suitability to particular applications.
