New ultra-high material efficient, low-cost solar cells — using nanowires
A new method using nanowires can make solar panels much more efficient and much cheaper than today.
UN Sustainable Development Goals: Responsible Consumption and Production

Is it too late to save the planet?
Code red for humanity, says the IPCC. Fortunately, there’s still a lot we can do, but we have no time to lose, says NTNU climate researcher Edgar Hertwich.
Provoking climate engagement
As you walk around the city, nature “pops up” in unexpected places. Like a “lung tree” – a tree that breathes. The Nature in Your Face research project wants to use art to create engagement.
Ammonia – the key to making long-haul shipping green
Relatively simple adaptation could make the cargo ships of the future completely green. The technology is based on the chemical compound ammonia, some extensive number crunching and one or two engine modifications.
Artificial intelligence makes it easier to study wild fish at salmon farm sites
New technologies, including artificial intelligence, allow us to study salmon behaviour and their living environment in large-scale commercial sea cages.
Robots with visual and tactile sensing can prevent tons of food waste
Intelligent food handling by robots can boost productivity and reduce waste in the production chain. Meet the robot with visual and tactile sensing, capable of handling compliant food objects.
Silicon for solar cells becoming more environmentally friendly
New discoveries are making silicon production cleaner, and solar cells of the future will become even more environmentally friendly.
Abandoned cropland should produce biofuels
More biofuels are needed to counteract climate change. But producing them shouldn’t diminish food production or wilderness areas. The solution may be to grow more grass on recently abandoned cropland.
Reveals hungry salmon with sound waves
The feed cost represents about 50 percent of the costs of farming salmon. But how do we know if the salmon is hungry or still full? Researchers have rethought to find answers. The result is less wastage and pollution – and enough food for the salmon.
Bioplastics no safer than other plastics
Bioplastics contain substances that are as toxic as those in ordinary plastics.
Successful utilisation of every single gramme of fish
The rest raw materials left after a salmon has been filleted are equivalent to more than 60 percent of its slaughtered weight. It will soon be possible to convert these into a high-quality fish oil, taste-neutral fish proteins, fish gelatin and flame-retardant materials. Ensuring that not a single gramme goes to waste.
Cleaner fish being sacrificed in the fight against salmon lice
Research shows that even fish farmers have doubts as to whether using cleaner fish is an effective delousing method. “Fish farmers tell us that they want a ban on the use of certain species. They’re also very critical of wild-caught cleaner fish being transported,” says researcher Kristine Størkersen. She is one of the scientists who have been helping the Norwegian Food Safety Authority gain an overview of the situation.
Global supply chains as a way to curb carbon emissions
The coronavirus outbreak raised everyone’s awareness of the significance of global supply chains to modern economies. But global supply chains also play an important role in greenhouse gas emissions. How they are managed can either increase or decrease carbon emissions, new research shows.
More people and fewer wild fish lead to an omega-3 supply gap
Omega-3 fatty acids are essential components of healthy diets for both humans and fish. The dramatic increase in fish farming worldwide has boosted the demand for omega-3 fatty acids so much that today’s supply can’t meet demand. Reducing waste and finding new sources can help.
The most beautiful solar cells are inspired by nature
Organic solar cells are usually less effective than silicon solar cells. But there is still a market for them – and they’re beautiful and exciting.
