Abstract [en]

In this report a photon battery is presented as a new type of electrical energy storage. The battery charging is based on conversion of electricity into photons and these photons are absorbed by an energy storage material, which is therefore heated to high temperatures. To extract electricity when needed, photons emitted from the hot energy storage material can be converted back to electricity by photovoltaics. The basic principles of the energy cycle are presented and the efficiency of the photon battery is discussed. The maximum energy density for different types of materials are estimated and examples of application of photon batteries for low cost and large scale electricity storage is suggested, and higher energy density applications are also discussed.
