ULTRACAPACITORS FOR THE RAIL INDUSTRY

Significant savings for rail through decreased energy consumption and carbon emissions

Ultracapacitors are routinely used in light rail and smaller trains. They have been implemented on electric and hybrid trains and are becoming key to rail transport.

Ultracapacitors can be used to provide engine start power for locomotive trains. In addition, ultracapacitors can recover energy from a train braking and then provide additional power when the train begins to accelerate again.
Ultracapacitors have proven to be a superior technology for regenerative braking in hybrid buses and trucks and cold starting of diesel engines. These technologies can be applied in a similar way to rail vehicles.

Ultracapacitors for rail industry applications

Ultracapacitors have the potential to revolutionize the rail industry. Our technology can significantly improve train efficiency - reduce costs and CO2 emissions, increase energy savings and dynamics of the train. The implementation of ultracapacitor technology provides effective voltage stabilization for rail systems, greatly improves the performance of propulsion for light rail vehicles and significantly advances the locomotive engine starting technologies.

Hybrid / KERS for DMU

Many railway companies are still using DMU trains without any form of energy regeneration. It can result in penalties related to high CO2 emissions, high running and maintenance costs and heavy wear on brakes and transmission components. Skeleton Technologies is offering KERS (Kinetic Energy Recovery System), an on-board energy storage system, powered by our industry-leading ultracapacitors, which capture braking energy in trains to power acceleration and decrease carbon emissions. 

  • More freedom for line planning
  • Increased utilization of the train even in congested & polluted areas
  • Faster acceleration & less noise
  • Reduced peak load demand from diesel engine when accelerating
  • Service cost reduction (CAPEX and OPEX)
  • Improved fuel efficiency and reduced CO2 emissions

Engine Cranking for DEMU

Safety and reliability matter especially in extreme weather conditions of -40 °C. Sometimes transportation companies face situations when DEMU train fails to start, which results in a very costly downtime. The main reason why equipment fails to start is use of lead-acid batteries as power packs to get started. With Skeleton’s Engine Start Modules (ESM), which have the power density matching the requirements of starting procedure, transportation companies will never face battery-related start failures. 

  • No battery-related start failures anymore
  • ESM has the power density matching the requirements of starting procedure
  • 100% reliable & maintenance-free device
  • Safety & reliability even in extreme temperatures (-40°C to +65°C)
  • Over 1 million cycles & longer calendar life: 10+ years
  • Ultracaps are considerably lighter than batteries

Catenary-Free Operation

Sometimes the catenary is not entirely available for the planned route due to limitations regarding preservation orders in certain city quarters. In this case an on-board energy storage could be a perfect solution, providing energy in track sections without catenary. This application has several significant advantages: no catenary-related constructions needed (fast and easy implementation) and lower public grid connection costs (energy is being regenerated when the train is braking).

  • High performance operation with an integrated compact design
  • Increased energy efficiency – energy regeneration when braking
  • No catenary-related constructions
  • Reduced peak load demand from grid when accelerating
  • Reduced public grid connection costs
  • Over 1 million cycles & longer calendar life: 10+ years

Wayside Energy Storage

Most catenary systems are not capable of feeding energy back to the grid. With our solution the excess of energy is being saved to the wayside energy storage, installed at several train stations. When train accelerates, it draws the energy from ultracapacitors. Fast charging in seconds is available both for on-board and wayside energy storage solution. It provides fast charging of light rail vehicles within seconds. The energy storage absorbs energy and supplies the vehicle enough energy to reach the next couple of stations. 

  • Up to 20% energy cost reduction
  • Increased productivity – charging when passengers are boarding
  • Increased energy efficiency - energy regeneration when braking
  • Offers a higher degree of freedom for line planning
  • Catenary supply peak load reduced
  • Lower public grid related cost
