Customer: Zero Emission Services (ZES)
Market: Transport & Logistics
Solution: Docking station with charging infrastructure for carbon-neutral ship


  • Power of 2MWe
  • Charging batteries from the public grid and by solar fields and wind farms, discharging by loading trucks and containers from ships and providing energy for the FCR market
  • Turnkey delivery

ZES is a startup that aims to make inland navigation CO2 neutral, funded by ENGIE, ING, Wärtsilä and Port of Rotterdam. It does so with an emission-free shipping infrastructure accessible to all. The solution consists of swappable battery containers, called ZESPacks, which are filled with sustainably generated electricity from the Netherlands. For swapping the battery container, a network of publicly accessible charging points has been set up along main shipping routes and strategic locations at terminals. The empty ZESPacks are exchanged there for full ones, allowing ships to sail quickly with minimal waiting time.

When not deployed on board, the batteries can be used temporarily on land to stabilise the power grid or to meet local temporary electricity demand at events or construction sites to replace diesel generators. Electroproject built the solution, but also helped develop protocols and standards. These should ensure that all batteries fit on any charge switching station and can also be connected to any ship.

Heineken has committed to ZES for ten years to transport beer emission-free from its Zoeterwoude brewery to Moerdijk, sending an important signal of confidence and a big step in sustainable transport.
