Epoxycyclopentane hydrate for sustainable hydrate-based energy storage: notable improvements in thermodynamic condition and storage capacity.

We suggest epoxycyclopentane (ECP) as a novel guest compound for hydrate-based energy storage. All of the key properties of the ECP hydrate, including the thermodynamic stability, storage capacity, and formation condition, are notably superior to those of hydrates containing tetrahydrofuran (THF) and cyclopentane (CP), currently considered to be the most powerful promoters.
