Novel (potential field-based) super flywheel type high capacity kinetic energy storage

Traditional energy storages suffer with:

- Low scalability (in terms of total energy capacity)
- Slow charging rate
- Major decrease of total capacity in harsh climate conditions

Working principles

FES (Flywheel Energy Storage) is a body (rotor) being spinned up by external energy. During acceleration process FES is storing energy and then can return it in the electrical or mechanical form in a short or long period. FES is connected to the electrical machine, which charges and discharges it. The amount of stored energy depends on the mass, dimensions and rotation speed of a flywheel.

Traditionally, FES has a drum unit, putted in the vacuum chamber to reduce friction losses. For flywheel manufacturing may be used conventional steel or titanium ribbon or even modern carboxylic or special rubber types, fixed on the center made of the elastic material with a high uniaxial strength.

Using of "flexible flywheel " and charged energy of a rotating body and potential field of deformations is promising technology. These methods will reduce the manufacturing cost , increase efficiency and allow to produce energy even during the spin up.

Tasks

- Novel high-capacity kinetic energy storage development is based on FES and nowadays potential field approaches – up to 0,5 kWh per 1 kg of mass
- Increasing energy supply systems robustness  for the regions with unstable power grid
- Reduction of the overall costs of battery segment
- Ultrafast charging – depends only on the current input power from power grid
- Innovative scientific and engineering approaches
