But batteries are toxic, explosive, and they lose their capacity with time and deep discharge cycles. Inventor Bill Gray thinks that his innovative flywheel design – the VEry Large Kinetic Energy Storage System (Velkess) – will supplant batteries in the renewable energy sector. Gray has applied for a patent on the design. Image: Kickstarter
Flywheel Energy Storage Systems (FESS) work by storing energy in the form of kinetic energy within a rotating mass, known as a flywheel. Here''s the working principle explained in simple way, Energy Storage: The system features a flywheel made from a carbon fiber composite, which is both durable and capable of storing a lot of energy.

Flywheel Systems for Utility Scale Energy Storage is the final report for the Flywheel Energy Storage System project (contract number EPC-15-016) conducted by Amber Kinetics, Inc. The information from this project contributes to Energy Research
Velkess flywheel technology promises cleaner, more efficient energy storage. It''s no secret that the successful future of wind, solar and other renewable sources hinges on the development of cost effective energy storage systems. Silicon Valley inventor Bill Gray believes his novel approach to flywheel technology could be the answer
In this paper, state-of-the-art and future opportunities for flywheel energy storage systems are reviewed. The FESS technology is an interdisciplinary, complex subject that
By absorbing energy when there is an excess and serving energy when there is a lack, storage makes reliable always available power from intermittent clean generation. Velkess has developed a new energy storage technology designed from the ground up to provide high quality, long life, energy storage at dramatically lower cost than batteries.
Lets check the pros and cons on flywheel energy storage and whether those apply to domestic use ():Compared with other ways to store electricity, FES systems have long lifetimes (lasting decades with little or no maintenance;[2] full-cycle lifetimes quoted for flywheels range from in excess of 10 5, up to 10 7, cycles of use),[5] high specific energy (100–130
Compared to Beacon''s flywheel, the Velkess can store electricity at only $300,000 per megawatt-hour, only one-tenth of Beacon''s costs. The company focuses on stationary Energy Storage across all applications from Residential, Self - Consumption and Microgrid through to large scale stationary storage. We are Europe''s first conference
This concise treatise on electric flywheel energy storage describes the fundamentals underpinning the technology and system elements. Steel and composite rotors are compared, including geometric effects and not just specific strength. A simple method of costing is described based on separating out power and energy showing potential for low power cost
I''ve been looking into flywheel energy storage as a possible alternative to various types of batteries and other means such as compressed air and hydrogen. I''ve come across some interesting facts and this may be more practical than I first thought.
I''m not sure what''s so special about a velkess flywheel. It just looks like a non-rigid flywheel that''s afixed a certain way that allows it to wobble around without affecting the mounting point. Beacon Power will design, build, and operate a flywheel energy storage frequency regulation plant at the Humboldt Industrial Park in Hazle Township
Gray''s creation is coined Velkess, for VEry Large Kinetic Energy Storage System. The Velkess flywheel''s design allows for more than 80 percent efficiency and is expected to store 15 kilowatts per hour, which is enough to run an average home for one day. The cost of a flywheel energy storage system is $6,000.
Design of flywheel energy storage system Flywheel systems are best suited for peak output powers of 100 kW to 2 MW and for durations of 12 seconds to 60 seconds . The energy is present in the flywheel to provide higher power for a shorter duration, the peak output designed for 125 kw for 16 seconds stores enough energy to provide 2 MW for 1
Velkess is working on a prototype flywheel storage unit that''s small enough for distributed generation applications. The unit would have about the footprint of a typical home refrigerator, says Gray. The unit would be able to store 15,000 kilowatt-hours of electricity, losing only about 2 percent of its stored power to friction each day.
The advantages of flywheel energy storage over battery usage include longer serviceable life; reduced fire risk; and reduced use of heavy metals. Additional advantages of the STORNETIC system include its capacity for rapid charge and discharge, and the very low maintenance requirement associated with almost frictionless technology that can
Ricardo (Shoreham-by-Sea, West Sussex, U.K.) launched its TorqStor high-speed flywheel energy storage unit at the CONEXPO 2014 show in Las Vegas on March 4. In a 17-tonne The table below shows projected cost figures given in the 2011 ORNL report with an additional line item for the Velkess flywheel, developed by Silicon Valley inventor
An overview of system components for a flywheel energy storage system. Fig. 2. A typical flywheel energy storage system [11], which includes a flywheel/rotor, an electric machine, bearings, and power electronics. Fig. 3. The Beacon Power Flywheel [12], which includes a composite rotor and an electric machine, is designed for frequency
The Velkess Flexible Flywheel promises energy storage technology at a "radically lower cost." Think of a house with solar panels on the roof. Think of a house with solar panels on the roof. During the day the house receives enough energy from the Sun to power the lights, heat, air conditioning and appliances in the house.
Velkess, a startup run by Bill Gray, uses fiberglass on a lightweight frame to prove his cheaper kinetic energy recovery system can work in something like a renewable home installation.

A review of flywheel energy storage systems: state of the art and opportunities. Energiestro promotes a flywheel made of concrete, claims that it "will decrease by a factor of ten the cost of energy storage." Similarly, Velkess has proposed a flywheel made of e-glass. However, both materials have very low tensile strength, it is not
