ABSTRACT:
A thermal energy storage device includes a sealed container having a wall defining a receptacle. An energy storage medium is disposed in the receptacle. The energy storage medium includes water and a gas capable of forming a gas hydrate with the water at a first transition temperature, the gas hydrate being capable of decomposing into water and the gas at a second transition temperature. Additionally, a fin extends from the wall inwardly to an inner region of the receptacle. The fin is in thermal communication with the wall, and defines a thermal energy transfer path between the wall and the inner region of the receptacle to facilitate the decomposition of the gas hydrate into water and the gas. The thermal energy storage device may also includes a mechanism positioned in the receptacle for providing mechanical movement within the thermal energy storage medium and mechanical contact between structural elements of the thermal energy storage device to facilitate the formation of the gas hydrate.
