Crystal clear political message
In 2018, the Norwegian parliament decided that no tourist or cruise ships should use fossil fuels in the fjords in Western Norway from 2026 onwards. Under the Action Plan for Green Shipping, the government aspires for all Norwegian ports to be zero-emission by 2030.
“The political message is crystal clear. For there to be continued growth in shipping and tourism in Western Norway, their climate impact must be significantly reduced. Our plans will enable and facilitate the kind of sustainable development of the region’s shipping and tourism that is wanted, while simultaneously creating hundreds of new jobs”, says Rygg.
Bergen’s municipal master plan sets out a goal of reducing greenhouse gas emissions by 50 percent by 2030. Since March 2020, Vy Fjord1 Reiseliv has already been operating hybrid electric vessels, and from the turn of the year it will start using fully electric, zero-emission vessels.
Unique use renewable energy solutions
The ambition is to build the first zero-emission port capable of generating, storing and using its own energy, thereby minimising the strain on the local electrical grid. The zero-emission port will have a 1.3 km long quay front where cruise ships, cargo ships and high-speed craft can dock and be resupplied with whatever fossil-free energy source they need – electricity, hydrogen or ammonia.
In practice this will involve developing an energy hub combining shore power, battery storage technology, solar panels and thermal energy.
“This energy system will provide sufficient power for shore power and for charging ships, so that we minimise the strain on the electrical grid. Kildn will thus facilitate the transition to a greener future for shipping. We will require all large cruise ships to operate in zero-emission mode when sailing in and out of the port. Building a new port where this has been planned from day one is a unique opportunity. Nothing like it exists at the moment”, says Rygg.
The idea is to achieve this by using an optimal balance of four different potential renewable energy sources:
- 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.
- Approximately 23,000 m2 of rooftop solar panels will cover a significant proportion of the facility’s energy consumption.
- 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.
- 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.
