Energy storage explained: the difference between hybrid inverters and battery inverter…
The main difference with energy storage inverters is that they are capable of two-way power conversion – from DC to AC, and vice versa. It''s this switch between currents that enables energy storage inverters to store energy, as the name implies. In a regular PV inverter system, any excess power that you do not consume is fed back to the grid.

Superconducting Magnetic Energy Storage: Status and Perspective
Abstract — The SMES (Superconducting Magnetic Energy Storage) is one of the very few direct electric energy storage systems. Its energy density is limited by mechanical considerations to a rather low value on the order of ten kJ/kg, but its power density can be extremely high. This makes SMES particularly interesting for high-power and short ...
