Renewable energy in power grid using flywheel energy storage system, technology by using partial magnetic levitation

Storage of energy is necessary in many applications because energy may be needed when it is not available and may be available when not required. Sometime the needed energy may exhibit some peaks where the supply energy may be uniform in character. Energy can be stored in many ways .It is seen that kinetic energy storage in flywheel provides the highest specific energy compared to any other alternative source. Especially when the flywheels are made with composite materials they provide very high efficiency. In this paper flywheel has been analyzed using FEA (Ansys12.0) for various materials and specific energy has been calculated.
