why can light energy storage be used to store energy
Storing energy with molecular photoisomers
Artificially, solar energy can be stored as chemical energy, e.g., via electrochemical water splitting for hydrogen production. At the current stage, the highest artificial photosynthesis efficiency can reach 22.4%. 6 An alternative way of storing solar energy is to use photoswitchable molecules.

A common approach to thermal storage is to use what is known as a phase change material (PCM), where input heat melts the material and its phase change — from solid to liquid — stores energy. When the PCM is cooled back down below its melting point, it turns back into a solid, at which point the stored energy is released as heat.

A technology capable of harvesting lightning energy would need to be able to rapidly capture the high power involved in a lightning bolt. Several schemes have been proposed, but the ever-changing energy involved in each lightning bolt renders lightning power harvesting from ground-based rods impractical: too high and it will damage the storage; too low and it may not work. Additionally, lightning is sporadic, and therefore energy would have to be collected and stored; i…
