HEDGEHOG SYSTEM

Save and reuse braking energy from trains and metrotrains

Train helps train

Save braking energy, reduce finedust and stabilize the voltage of overhead lines to increase acceleration

Train helps grid

Avoid heavy upgraded grid connections locally and stabilize the grid nationally

Train helps e-mobility

Fast charge e-mobility with recycled green energy from trains and metrotrains and renewable energy sources

Het Hedgehog System

The Hedgehog System™ enables regenerative braking, which means that energy that is otherwise wasted can be stored to charge electric buses. Regenerative braking reduces particulate matter and erosion. In addition, the possibility of connecting the rail infrastructure via a large battery will relieve pressure on the public energy network in the coming years.

Het Hedgehog Systeem

Het Hedgehog Systeem maakt regeneratief remmen bij treinen mogelijk waardoor energie die anders verloren gaat, opgevangen kan worden om vervolgens elektrische bussen mee op te laden.  

Regenerative braking energy

At the train stations, braking energy and so-called “fresh energy” are extracted via a physical connection with the overhead lines.

Energy House

The energy is then stored in the battery of the internationally patented Hedgehog System ™. In addition to the (braking) energy that is extracted from the overhead line, local renewable energy from solar panels is stored in the battery and a bi-directional smart grid connection with the public energy grid is available.

E-mobility

Finally, the battery in combination with the superchargers is suitable for simultaneously charging fleets of electric buses.

Scalability of the system

The Netherlands has a high railway density and about 400 train stations. Based on the expectations regarding electric public transport in relation to the potential of braking energy, it is estimated that the Hedgehog System™ can be installed at 60-65 intercity stations.

The possibility to connect the rail infrastructure via the Hedgehog System™ to the charging infrastructure for e-buses provides an integral electric public transport chain. It thereby contributes to an acceleration of the energy transition, because the energy supply from the overhead line is regulated and therefore no problems will arise with the local energy grid in the urban areas around stations.

Patent braking energy trains, metro’s and trams

In 2015 Hedgehog Applications B.V. has been granted the patent: ENERGY DISTRIBUTION AND CONSUMPTION SYSTEM FOR RAILWAY STATION NR PCT/NL2014/050160. The patent describes the connection between all existing technical components necessary to store and reuse the regenerative braking energy from trains, metro’s and trams.e slaan en te hergebruiken.
