Flywheel technology is ideally suited for electrified rail and subway systems, offering green, cost-effective energy storage and recycling solutions. Not only can braking energy be captured and stored, but flywheel systems can also provide voltage support supplementing existing rail traction power substations. Metro transit agencies can benefit with improved performance, lower capital costs, and reduced energy usage.

Unlike other energy storage technologies, such as batteries and supercapacitors, which consist of hundreds or thousands of small voltage cells connected in series and in parallel, the VYCON native 750 Vdc or 1500 Vdc motor generator provides a bulk source of energy storage and provides:

• The highest reliability and availability
• The ability to operate continuously for a 2-minute headway metro operation without compromising product life
• The lowest life-cycle cost, lowest maintenance and operational costs and lowest installed costs
• The smallest footprint per kWh of storage
• Fast and simple installation and commissioning (can be done by the operator)
• Scalability through parallel REGEN systems to increase storage capacity
• No interruption to metro rail operations or performance degradation over time due to any and all of the following:
  • Number of cycles
  • Energy amount of each cycle
  • Hours of operation
  • Ambient temperature
  • Size of the energy storage installed
