Wayside energy storage systems
Hitachi Energy energy storage systems are available for the standardized traction voltages of 750 V and 1500 V and can be used in urban transport systems, suburban and mainline railways. Other voltages can also be provided. In addition to the ability to recover braking energy, the energy storage systems also offer other important possibilities.
Australia''s captures, stores and regenerates braking energy
Technology company ''s 1,500 Volt DC Enviline wayside energy storage system (ESS), a three-year project, captures braking energy and then returns it for the the acceleration of other trains which later use the same line section.

Energy storage offers a solution by smoothing out these power variations, absorbing energy as system voltage rises, and delivering energy as voltage drops. This guide will aid engineers in identifying where these solutions can provide the greatest benefits, designing solutions with the greatest impact, and quantifying the costs and benefits of
THE APPLICATION OF WAYSIDE ENERGY STORAGE SYSTEMS
Wayside Energy Storage Systems (WESS) introduce savings in the costs of the electric energy supplied to the railway catenary, by reducing the peak load and also the total energy demand (if locomotive regeneration is available).
Impact on railway infrastructure of wayside energy storage systems
Among the various on-board or wayside measures proposed, one of the most promising solutions is based on using wayside energy storage systems (WESSs). A WESS is a storage installation which can be integrated into mass transit systems in urban areas as well as into long-distance railway lines.
