While the farming of salmon does help take pressure off wild stocks, the feed used to raise the fish still isn't entirely sustainably sourced. That may change, however, thanks to nutrient-rich worms that eat readily available seaweed.

Norway has a lot of coastline and many fjords, but not much in the way of open ground on which to build runways. That's where the Elfly project comes in, as it's developing a short-haul electric seaplane that can take off and land in city harbours.

It's important for fish farmers to keep track of the number of fish in their pens, but doing so involves going in and actually netting out some of the fish. According to new research, echo-sounding tech could soon serve as an easier alternative.

While ocean-based fish farms do help take pressure off of wild stocks, they have eco-unfriendly drawbacks of their own. A new underwater robot is being designed to address that situation, by autonomously inspecting the fish and their pens.

If you're in a road tunnel that suddenly gets filled with smoke due to a vehicle fire, it can be very difficult knowing which way to head. That's where EvacSound comes in, as it uses audio beacons to guide people to safety.

​It was a couple of years ago that we first heard about the Eelume, an eel-like robot designed to perform underwater maintenance and inspections. Well, the latest version of the device, known as the EELY500, is about to begin sea trials in Norway.

The rapid growth of solar arrays and wind farms might sound like a win for the environment, but storing renewable sources of energy efficiently on the grid​ remains a challenge for energy providers. EU scientists are turning to a cheap and plentiful natural resource for the answer: air.

Ordinarily, when a ship is heading into waves, those waves cause it to work harder. An experimental new setup known as a "whale tail," however, utilizes wave action to actually help ships move forward, allowing them to use less fuel when tackling rough seas.

Pulling chicken breasts off the bone can be a fiddly process, and often results in flesh being wasted by getting left behind. In a factory setting, that means slower processing times, and less meat to sell. That's why the Norwegian CYCLE project is developing an industrial robot to do the job.

When it comes to robots that perform internal inspections of water pipes, virtually all of them move along on rubber tires or treads. The European Union TRACT project is instead developing a propeller-driven inspection robot, that keeps the pipe-touching to a minimum.

Earlier this year Rolls Royce outlined a future where giant robot cargo vessels ply the world's sea lanes without a human crew on board. That scenario is now coming closer to reality as the EU project MUNIN looks into the feasibility of robotic freighters and the hurdles they must overcome.

The APRICOT (Automated Pinbone Removal In Cod and WhiTefish) project set out in January, 2012 to find an automated solution that would keep fish processing in Scandinavia and has now developed a machine that achieves just that.
