Your life depends on these rare raw materials
The green transition is impossible without a few relatively unknown substances. Find out more about the raw materials we cannot manage without – and why we have to act smart with them.

Ammonia may hold key to greener combustion
One way to reduce flight shame may lie in a ring of flames. And in the gas that’s generated in an outhouse.
This is what you need to know about CCS – Carbon Capture and Storage
Why is there so much talk about storing CO2 underground? Doesn’t it cost more than it’s worth? Here we provide the research scientists’ answers and explanations of why CCS is climate technology that we are completely dependent on. And yes, this can be performed in a safe manner.
This technology replaces coal power with wood power
The Norwegian company Arbaflame is intent on persuading the world to abandon polluting coal power. The new technology makes it possible to replace coal with eco-friendly wood pellets.
Fewer cows, more trees and bioenergy
Combatting global warming will require major changes in land use, a new climate change report says. One important change could be decreasing the amount of land used to produce livestock — which means that people would have to eat less meat.
Renewable energy also viable in developing countries
How can we supply renewable energy to Indonesia, whose large population is spread over more than 6,000 islands?
Well-meaning climate measures can make matters worse
Lifestyle changes can reduce our greenhouse gas emissions and help protect nature. While some actions offer great potential, some aren’t as effective as we think and may even require more land and water, such as shifting to renewable energy.
“The fabric of life is disintegrating”
“Human beings are destroying the nature that we are all a part of,” says the winner of the Gunnerus Award in Sustainability Science, Professor Sandra M. Díaz.
Earth’s population could shrink soon
Better opportunities for women mean that the threat of overcrowding the planet may not be as dramatic as people fear. The population may well decline in a few decades.
Michelin-class composting
Now you can learn how to compost food scraps from a Michelin restaurant. Restaurant Credo folks in Trondheim will be showing off their artistry at the FUTURUM exhibit, part of NTNU’s science festival The Big Challenge.
Gas instead of coal is 50% better for the climate
We can do a lot to save the climate by switching from coal to natural gas. And we can shelve concerns about the negative climate impact of methane emissions from gas production, say researchers.
Finding ways to use less salt on snowy roads
It’s springtime in much of the northern hemisphere, although spring snowstorms are still possible. When that happens, salt trucks and ploughs help make roads safe. But road salt can be bad for the environment, and can rust cars, bicycles and other metal. New research shows that salt use can be safely — and substantially — cut in certain circumstances.
Gunnerus Award goes to expert on biodiversity
Ecology professor Sandra Myrna Díaz is the winner of the 2019 Gunnerus Award in Sustainability Science.
When the Chinese giant awakes
When China sets its sights on a goal, the country can change at a blindingly rapid pace. Now the country is focused on innovation and technological innovations, with renewable energy at the forefront.
Norwegian trees can power our jets
As much as 20 per cent of jet fuel burned in Norway in 2030 could be biofuel made from the country’s forest residues. This alone could cut greenhouse gas emissions from Norway’s aviation sector by 17 per cent.
Spending our carbon budgets wisely
Our carbon emissions are much higher than are needed for us to have happy, healthy lives. But cutting these emissions requires us to think differently about how we measure growth and progress.
Ecolabels alone don’t work
NTNU researchers wanted to see if labelling products and putting up signs in stores would encourage more consumers to buy sustainable seafood. The results showed that customers bought significantly more seafood generally – including options that were not sustainably harvested.
Geoengineering, other technologies won’t solve climate woes
The countries of the world still need to cut their carbon dioxide emissions to reach the Paris Agreement’s climate targets. Relying on tree planting and alternative technological solutions such as geoengineering will not make enough of a difference.
Minerals and Materials for a Sustainable Future
For the first time this week, the Nature Research Group, publishers of Nature, will host an international conference in Trondheim in cooperation with NTNU, SINTEF and the Geological Survey of Norway. The theme for the conference, which runs from 11-13 September, is the sustainable use of minerals and materials.
New super laboratory coming to Trondheim
Research on minerals and materials is important in helping society make the transition to a greener economy. NTNU, the Geological Survey of Norway and SINTEF have joined forces to establish a national laboratory to that end.
Coastal cruise ships with wings on the bow are on the way
Ships with wings? Researchers are piloting this NTNU-spawned technology on new coastal cruise ships now being tested in Trondheim. The wings – or foils – use less fuel and make the journey more comfortable for passengers.
Clothing, furniture play a role in ocean and freshwater pollution
Lakes choked with algae and marine “dead zones” result from too many nutrients in the water. The traditional culprit is agriculture, which relies on fertilizer to boost plant growth. But the production of consumer goods, like clothing, is also a major — and growing — contributor.
Debatable whether Norway will become Europe’s green battery
Can Norwegian hydropower and natural gas play a role in Europe’s future power market? Results of a recent study show that Europe needs to craft a new and shared vision for energy policy for Norway to be a player.
New filter removes run-off chemicals
The filter will first be used to recover aircraft de-icing chemicals. In the future it will also be used in urban areas to remove environmental toxins, pollution and probably microplastics.
