Nguyen et al indicated that the liquid NMR signals vanished when lowering the temperature down to 243 K, attesting the absence of lattice defects in the THF hydrate at low temperatures. Hence, lowering the temperature helps rectify the dopant-induced defects and lock the gas molecules securely in the water lattice for storage. This NMR-informed conclusion is supported by the recent study by Linga et al who reported that methane can be kept in a mixed dioxolane/methane hydrate at the temperature lowered to 268 K under the atmospheric pressure , suggesting that the stable rigid water lattice at such a lowered temperature could hold the encaged gas molecules securely without the need of pressures.
