Wayside energy storage solutions
Light rail transport: challenges and goals
Metro and trams have high and variable energy consumption, sometimes coupled with aging systems struggling with voltage fluctuations.
At the same time, cities are committing to ambitious carbon emission reduction targets, involving the promotion of public transit and increase of its energy efficiency to reduce the environmental impact of transportation.
Smart and sustainable solutions are needed to meet the CO2 reduction targets and cut energy costs.
Energy storage for regenerative braking
Wayside energy storage for rail is typically located in, or close to a rail traction power substation.
Our flywheels enable the storage of energy recovered from the deceleration of electric vehicles, transmitted via the overhead power lines or third rail. This recovered energy is then used by an accelerating vehicle in proximity of the traction power substation, reducing the net energy usage.
With Teraloop´s solutions, the energy retrieved from regenerative braking can be used to start metros and trams in asynchronous moments, without the limit of concurrent operation where regen and load are occurring simultaneously.
At the same time, flywheels are also commonly used to rectify power quality and thus can further contribute to voltage control in outdated systems.
Our compact, fire safe, and efficient kinetic energy storage solutions can service a station over more than 25 years.
They are designed to endure the numerous daily cycles required and can be customized to match the needs of our customers.
