Abstract

The invention is directed at devices 10 and systems 120 for thermal energy storage, and far process, of storing energy using these devices and systems. The devices include a flow path 4 that includes a plurality of sections that are arranged to reduce or minimise heat lessee from the device from heat flow along the flow path. The flow path 4 preferably includes two or more caged flow path sections 20. The device includes :.a thermal energy storage material 2 suitable for storing heat, The devices may be particularly useful for storing heat for Long periods of time.
