Skeleton Technologies ultracapacitor rail applications

Wayside
energy storage

Up to 20% energy cost reduction

Benefits of our solution

  • Up to 20% energy cost reduction
  • Increased energy efficiency
  • Catenary supply peak load reduced​
  • Lower public grid related cost

Challenge

Safe & efficient braking energy recovery


KEY CHALLENGES

  • Catenary systems are not capable of feeding energy back to the grid
  • Catenary systems cannot fulfill the increased demands of modern rail systems

  • known consequences
  • Catenary systems are limiting the productivity due to lower peak power capabilities
  • Energy regeneration can cause power quality issues
  • The regenerated energy is burned off in brake resistors to avoid high power peaks
  • Electrical equipment must be capable to handle existing power peaks and transients

solution

up to 20% energy cost reduction

  • what we offer
  • Wayside KERS (Kinetic Energy Recovery System) captures energy during braking of a train arriving at the station, and provides energy during the acceleration of a train leaving the station
  • ADVANTAGES OF OUR PRODUCT
  • 100% reliable energy storage with zero maintenance
  • Over 1 million cycles & longer calendar life: 15 to 20 years
  • -40°C to +65°C operating temperature range

    Advantages over Li-ion battery solutions:
  • Smaller and cheaper vs. a solution of similar requirements
  • The battery needs to be oversized to cater for peak loads
  • Higher safety – no smoke, fire or flame
  • Longer lifetime of the wayside KERS system
