Delivery agreement with Grieg Star – a major breakthrough for Grenland Energy
A delivery agreement with Kongsberg Maritime and shipping company Grieg Star represents a major breakthrough for Grenland Energy, and the company’s four founders are delighted.

Together with their main owner Kongsberg Maritime, the founders have developed a solution for Grenland Energy’s battery system, where the energy produced when a ship crane loads cargo can be stored and used for the next loading, much in the same way as electric cars charge their battery whenever the car brakes. The return power is stored in batteries, and the result is saved power, reduced emissions and lower maintenance costs.
Grieg Star will now install the equipment on one of its 10 L class ships, with the support of NOK 1.15 million from ENOVA. If the project is successful, nine new identical ships will be ready for their turn.
Two world records
Roman Stoiber explains that the agreement with Grieg Star represents the company’s first all commercial delivery, and is of major importance for the further development of Grenland Energy. Last Christmas, technology company Grenland Energy gained Kongsberg Maritime as an owner, with positive results.
And the agreement with Grieg Star brings two new world records. “This will be the first major high-impact battery pack installed on a ship, and it will be the first time the batteries have been used as an energy buffer for crane operation on a ship,” says Peder Thysted.
Grenland Energy received support for developing the basic technology from research committee Vekst in Grenland, the Oslofjord Foundation and not least Innovation Norway's environmental technology scheme.
First of its kind
"This use of batteries could be the first of its kind in merchant maritime. Apart from reduced CO2 emissions, we will be able to contribute to better air quality in ports by also reducing emissions from SOX, NOX and soot particulates. An added benefit is that the cranes will become more effective so that docking time in the quay is reduced,” says Camilla Grieg, CEO of Grieg Star.
ENOVA believes battery solutions have major opportunities in the maritime sector. “The industry itself has highlighted a need for pilot projects that could activate several installations on board a ship. Now Grieg Star will pave the way and prove that new electronic solutions can help reduce emissions and costs,” says Petter Hersleth, marketing manager for transport in Enova.
All at Herøya
Now the work starts in earnest for Grenland Energy. The batteries have to be delivered to Grieg Start by the end of the year for testing on one of the boats. The batteries consist of wooden cabinets, weighing a total 1.5 tonnes. They have a capacity of 67 kWh, and when a load is dropped, they can charge 430 kW in 10 seconds.
“We now have to adapt the batteries, get them certified and then we have to make them, and it all happens here at Herøya,” says Roman Stoiber.
Meanwhile, the company is working on several enquiries and new customers, conducting tests and qualification work, developing quality systems and preparing for production. “Developing the company, organisation and technology will go hand in hand with production,” says Peder Thysted.
