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.

Six years into the ice — and beyond

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

NTNU cools down CERN

CERN’s two Large Hadron Colliders detectors to get a climate-friendly cooling system upgrade.

NOTES

NTNU will lead European sustainability project

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.

Conflicting consequences of climate change for Arctic geese

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.

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.

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.

Sun and wind in a box

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.

“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.

How stores can throw out less food

Grocery stores throw out 75 000 tons of food annually. By adding date tagging to the barcode, food waste could be dramatically reduced, say two NTNU students.
