Carbon dioxide may be stored within a gas hydrate of a subterranean formation. For example, compositions for storage of carbon dioxide in a gas hydrate may comprise: a carbon dioxide phase; and a nonionic surfactant that is at least partially dissolved in the carbon dioxide phase, the nonionic surfactant including a first polyalkoxylated alcohol and a second polyalkoxylated alcohol, in which each polyalkoxylated alcohol is a reaction product of an aliphatic alcohol and one or more of ethylene oxide, propylene oxide, and butylene oxide.
