Hydrogen as an energy carrier can help us move away from fossil fuels, but only if it is created efficiently. One way to improve efficiency is to use waste heat that’s left over from other industrial processes.
Energy and environment
If this solar and wind-based hydrogen project succeeds, it may become a model for many thousands of other small island communities worldwide.
By now it’s well established that microplastics are a problem in the environment, even in the remotest parts of the planet. But where do different microplastics come from and how they get there, especially in the Arctic?
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.
One way to reduce flight shame may lie in a ring of flames. And in the gas that’s generated in an outhouse.
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.
The Arctic’s once impenetrable ice cap is melting away, with profound consequences for everything from ocean circulation patterns to fish numbers and diversity. The Nansen Legacy Project, including NTNU biologists, chemists and engineers, is working to better understand what these changes mean for the Barents Sea and the Arctic Basin
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.
Through the Research Centre on Zero Emission Neighbourhoods (FME ZEN) in Smart Cities, NTNU has received funding from the EU to research sustainable plus energy neighbourhoods in Europe. SINTEF and OBOS are partners.
Climate change is the big wild card when it comes to the survival of many Arctic species. A new study shows that climate change will be both good and bad for Svalbard barnacle geese populations — although the balance may tip depending upon the severity of future temperature increases and how other species react.
Norwegian scientists have developed a material which can make hydrogen from water vapor, instead of liquid water. It pays off, because heat is cheaper than electricity.
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.
Climate frustration led three former NTNU students to quit their secure and well-paying jobs. Instead, they developed a digital toolbox for the green shift. Now the world is knocking on their door.
When energy researchers carry out experiments to investigate safe and efficient CO2 transport on the roof of the thermal power engineering laboratories at Gløshaugen, Trondheim, the noise they make will be like a jet engine.
How can we supply renewable energy to Indonesia, whose large population is spread over more than 6,000 islands?
The boat wings started as an unfinished idea in Eirik Bøckmann’s head. Now they’re being mounted on a ferry in the Faroe Islands.
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.
Renewable energy is fine, but often it’s needed at times other than when the wind is blowing or the sun makes an appearance. The energy needs to be stored – and a new method is on the horizon.
“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.
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.
We need to cut both global and local emissions from shipping. The picture is complex, but research is showing that there are many ways to meet this goal.
