A second class of distinction is the means by which energy is transmitted to and from the flywheel rotor. In a FESS, this is more commonly done by means of an electrical machine directly coupled to the flywheel rotor. This configuration, shown in Fig. 11.1, is particularly attractive due to its simplicity if electrical energy storage is needed.

Global industrial energy storage is projected to grow 2.6 times, from just over 60 GWh to 167 GWh in 2030. The majority of the growth is due to forklifts (8% CAGR). UPS and data centers show moderate growth (4% CAGR) and telecom backup battery demand shows the lowest growth level (2% CAGR) through 2030.
