Personalized energy will be possible only if solar energy is a supply that is available 24 hours a day, for 7 days a week. Hence, the key enabler for personalized energy is inexpensive storage. There are many methods of solar storage, however, the low energy densities of most of these methods present formidable challenges for the implementation of solar energy at the individual level. For example, the energy densities by mass of compressed air.
