Kinetic Energy Storage (KEST)
Technology
Kinetic-Power has developed a unique superflywheel-based energy storage system with wide range of industrial applications including electrical grids and infrastructure. Our energy storage system survives unlimited number of high-power 100% SOC discharge cycles without degradation or loss in capacity, while being completely eco-friendly and operationally safe.
Superflywheel
The two key elements of Kinetic energy storage (KEST) are superflywheel and powerful electric motor/generator
-
At the core of KEST lies superflywheel – a next-generation flywheel made of a solid core (hub) and multiple layers of high-strength steel ribbon wound around it
-
A single KEST unit may contain one or multiple superflywheels to adjust energy capacity depending on the application
-
Unique properties of the superflywheel make our storage unit completely operationally safe

Operating principles
KEST captures and stores electrical energy by converting it into kinetic energy of the spinning flywheel
-
To capture the energy electric motor spins up the flywheel (transforming electrical energy into kinetic energy of the rotating flywheel)
-
To store the energy electric motor is disengaged and superflywheel spins freely inside the chamber with low pressure
-
To release the energy electric motor switches to a generator mode and uses the kinetic energy of superflywheel’s rotation to spin the rotor and generate electrical energy
Forming an energy efficient enterprise model based on the data received from PowerBox
With the help of specialized software, on the basis of the data received from the Power Box, a mathematical model of the energy efficiency of your enterprise is being built. A comparative analysis of electricity consumption with and without the use of the Kinetic system is carried out.
And also there is a programming of the control system for a specific consumer.
