High-Power Energy Storage Solutions for Rail
Technology Leader for Supercapacitor Energy Storage in Rail
Skeleton Technologies is the global technology leader in ultracapacitor energy storage in automotive, transportation, grid and industrial applications.
We work with some of the largest companies in the world – from leading Tier One automotive firms and industrial equipment OEMs to truck fleet operators and aerospace prime contractors to decrease CO2 emissions and fuel consumption, to improve power quality and protect equipment and infrastructure from power peaks, and to power electrification to fight climate change.
Our ultracapacitors, based on patented “curved graphene”, represent the biggest technological advancement in the industry in the last 20 years and the use of this innovative material provides our products with an unparalleled advantage in power and energy density.
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.
At Skeleton Technologies, we offer four different solutions to improve train efficiency.
Catenary-Free Operation
