A FESS is an electromechanical system that stores energy in form of kinetic energy. A mass rotates on two magnetic bearings in order to decrease friction at high speed, coupled with an electric machine. The entire structure is placed in a vacuum to reduce wind shear [118], [97], [47], [119], [234].

This high-speed FESS stores 2.8 kWh energy, and can keep a 100-W light on for 24 hours. Some FESS design considerations such as cooling system, vacuum pump, and housing will be simplified since the ISS is situated in a vacuum space. In addition to storing energy, the flywheel in the ISS can be used in navigation.
In this design, pioneered by the California based company Advanced Rail Energy Storage (ARES) company in 2010 ARES North America (ARES North America - The Power of Gravity, n.d., Letcher, 2016), the excess power of the renewable plants or off-peak electricity of the grid is used to lift some heavy masses (concrete blocks here) by a
Thermal energy storage has become more and more important to improving the overall efficiency of energy systems by utilising the wasted energy.

The implementation of these optimal design options in the building model yields a NZEB with a positive energy balance, between load and generation, ranging from 7 kWh/y.m 2 to 10 kWh/y.m 2. Fig. 9 illustrates the optimized objective functions for each solution set in the studied regions.
7.2.2.2 Underground Storage. Underground thermal energy storage (UTES) is also a widely used storage technology, which makes use of the ground (e.g., the soil, sand, rocks, and clay) as a storage medium for both heat and cold storage. Means must be provided to add energy to and remove it from the medium.
The Energy Generation is the first system benefited from energy storage services by deferring peak capacity running of plants, energy stored reserves for on-peak supply, frequency regulation, flexibility, time-shifting of production, and using more renewal resources ( NC State University, 2018, Poullikkas, 2013 ).
