Looking to unconventional ways to cut carbon emissions
At Grieg Seafood we know that cutting carbon emissions and long-term profit go hand in hand, so we’ll consider any solution that benefits the planet.
“We are working to get our sites connected to the electric power grid here as well, but many are so far away from the grid that we need other alternatives.”

"A windmill and a solar panel on a salmon farm. That is something I never imagined,” says Ørjan Hadland.
He is a team leader at the Nordheimsøy farm, where Grieg Seafood Rogaland has installed the first ever solar panel on the roof and a windmill on the side of the feeding station. The aim is to partly substitute the diesel generator with renewable energy.
The idea came from master student Helleik Syse and meteorologist Siri Kalvig, who at the time was an Associate Professor at the University of Stavanger.
“Not all farms are situated in places close to the electric grid. This project is a pilot aimed at testing out whether windmills and solar panels can be used as an effective alternative,” says Helleik Syse.
SAVES THOUSANDS OF LITERS OF DIESEL
Most farms in Grieg Seafood Rogaland are already connected to the electric power grid on land. A few sites, however, still get their energy from diesel generators. Nordheimsøy is one such farm.
“Our aim is to be able to shut down the diesel engines when we leave work in the afternoon. The battery on the site, which has been charged all day from the windmill and solar panel, can then provide the farm with the energy it needs during the night,” explains Ørjan Hadland. He says they hope to save 36 000 liters of diesel annually.
“Combining the windmill and the solar panel will make it possible to cut carbon emissions with almost 98 tonnes of CO2 equivalents a year from this farm only,” Hadland states.
REDUCES HALF OF EMISSIONS WITH A NEW HEAT PUMP
Grieg Seafood Finnmark is also taking similar measures to reduce emissions.
“We are working to get our sites connected to the electric power grid here as well, but many are so far away from the grid that we need other alternatives,” says Jostein Iversen, Technical Coordinator at Grieg Seafood Finnmark.
He explains that diesel generators are not only bad for the environment, they are also costly and increase the need for maintenance on farming equipment.
“We are now investing in hybrid solutions for the far-off sites, where the diesel engines charge large batteries when they are running. With such solutions, we are able to reduce use of the generator with 85 percent,” Iversen says.
However, one investment makes a bigger difference than all other efforts at the farms.
“Our new heat pump at the Adamselv fresh water facility allows us to cut 2 275 tonnes of CO2 equivalents annually. That is about half of Grieg Seafood Finnmark’s total carbon emission. It is like removing more than 1 200 cars from the roads,” Iversen explains.
CLIMATE FRIENDLY DINNER
Farmed salmon has always had a small carbon footprint compared to other production of proteins. That does not mean, however, that the industry should stay out of the race to cut emissions.
“If we are to reach the targets of the Paris Climate Accord, all industries have to pull their weight. We have to take our part of that responsibility,” says Liv Marit Aarseth, Public Relations Manager at Grieg Seafood Rogaland.
“As we continue to seek more new solutions for cutting emissions, farmed salmon can be an even more climate friendly dinner alternative in the years to come.”
