Due to the high-energy density requirements of jumping movements, the power mainly comes from mechanical elastic energy (spring, rubber and other elastic components), chemical combustion energy, pneumatic or hydraulic systems, active deformation materials (shape memory alloys), and external field energy.
There are two basic types of energy storage that result from the application of forces upon materials systems. One of these involves changes in potential energy, and the other involves changes in the motion of mass, and thus kinetic energy. This chapter focuses upon...
If there is a leak, or the valve is opened, the gas stored in the tire is released. This is a simple example of the storage of energy in a gas. It is possible to store energy by making use of the elastic properties of gases in a manner similar to that of the elastic properties of solids.
They are generally housed in very robust steel containment, and large units are placed underground for safety reasons. Flywheels also store energy in the form of mechanical strain potential energy—like springs—due to the forces upon them. The magnitude of this potential energy is small, for example, 5 %, compared to their kinetic energy, however.
It is also possible to introduce a different type of mechanical energy into solid materials by plastically deforming them such that changes occur in their microstructure. These can involve changes in the concentrations or distributions of dislocations or crystallographic point defects during mechanical deformation or irradiation.
Whereas the efficiency of large-scale water-driven turbines can be quite high, even over 95 %, the efficiency of the dual-cycle reversible storage system typically is about 80 %.
These materials are, however, not isotropic, so that simple disc shapes are not practical. Instead, constant stress central shapes with high stress rims are often used. By use of such materials it is possible to achieve energy storage values as high as 200 kJ/kg in modern flywheels.
