The government’s aim is for all Norwegian ports to be zero-emission by 2030. It therefore makes no sense to plan a forward-looking new port that isn’t zero-emission and based on renewable energy. Nothing else would be sustainable or profitable in the long run. Our vision is to develop Norway’s biggest (and first) green zero-emission port for cruise ships and a fast ferry network. Our ambition is for the project to be completed in 2026.

So far, we have explored an energy model that involves the port being self-sufficient for renewable energy, so that it puts as little strain on the electrical grid as possible and can export any excess energy to the grid. It will be possible to install an energy storage system underground, and a microgrid with a smart energy distribution system will compensate for the extra power requirements of the port when ships are connected to shore power.

We will require all large ships and ferries that dock at the port to operate in zero-emission mode when approaching the port, which will also become a requirement at the Port of Bergen.

The idea is to achieve this by using an optimal balance of four different potential renewable energy sources:

  1. Sea water from a depth of 100 metres that will be passed through a heat exchanger and used to cool fresh water, which will be distributed around the facility to provide cooling.
  2. Approximately 23,000 m2 of rooftop solar panels will cover a significant proportion of the facility’s energy consumption.
  3. Underground battery storage system to provide extra power for shore power. That will help to reduce the need to draw electricity from the grid on Askøy.
  4. A seawater pumped storage power station where water is pumped up to a great height when power and energy is available, and then released through a turbine when power and energy are required. This serves the same purpose as the battery, and it will also be built underground.
