Rotor speed control of flywheel energy storage

Compared with other ways to store electricity, FES systems have long lifetimes (lasting decades with little or no maintenance; full-cycle lifetimes quoted for flywheels range from in excess of 10 , up to 10 , cycles of use), high (100–130 W·h/kg, or 360–500 kJ/kg), and large maximum power output. The (ratio of energy out per energy in) of flywheels, also known as round-trip efficiency, can be as high as 90%. Typical capacities range from 3 to 1. Flywheels can store energy kinetically in a high speed rotor and charge and discharge using an electrical motor/generator. Wheel speed is determined by simultaneously solving the bus regulation and torque equations.

Lithium manganese oxide batteries and energy storage

A lithium ion manganese oxide battery (LMO) is a that uses ( MnO 2), as the material. They function through the same /de-intercalation mechanism as other commercialized technologies, such as ( LiCoO 2). Cathodes based on manganese-oxide components are earth-abundant, inexpensive, non-toxic, and provide better thermal stability.
