A top priority of public authorities on all levels in the North Sea Region area is stimulating clean transport solutions powered by clean renewable energy.

Due to a difference in demand and supply of renewable energy, electric vehicles are not always charged with renewable energy and electrical grid instability is an actual concern.

The challenge is to structure the system in such a way that electric vehicles will be charged by locally produced renewable energy.

These objectives will be realized by using the EV batteries as a short term storage of renewable energy, through bidirectional chargers. This technique is known as Vehicle to Grid (V2G), and allows to balance out the curve of power demand over the day. This means that the electricity system is able to assimilate a higher amount of renewable energies and more electric vehicles.

Without Vehicle to Grid:


With Vehicle to Grid:


SEEV4-City distinguishes itself from earlier smart charging and V2G initiatives with operational, long term pilots in 5 cities in 5 European countries:



 The operational pilots will exhibit the V2G potential at different scales, and aiming for the same three goals:

  • An increase in energy autonomy.
  • An increase of ultra-low emission kilometres.
  • Avoiding extra investments to make existing electrical grids compatible with an increase in electro mobility and local energy production.



The project results will be a key enabler for:

  • innovative city development integrating clean electric transport services and renewable energy generation,
  • the introduction of new businesses for renewable energy and ultra-low emission mobility services, and
  • social acceptance studies, management guidelines and policy frameworks.
