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.
How to make shipping environmentally friendly
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.
Mission control: Norwegian SciTech News has landed!
We’ve changed our name to Norwegian SciTech News — so readers know immediately what they will find here.
Energy from algae coming your way
We need batteries that can store more energy. Algae may be a solution.
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.
Offshore wind-scientist appointed Mission Innovation Champion
John Olav Tande at SINTEF is appointed Norway’s Mission Innovation Champion for his innovative research and contribution in dissemination. The award was established by Bill Gates and among others former president Obama during the climate summit meeting in Paris, COP 21.
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.
Clean water eliminated effects of discharged drugs in fish
The discharge of pharmaceutical drugs is a major problem around the world, but a new study of the freshwater fish burbot shows that there is hope.
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.
Reindeer adapt to climate change by eating seaweed
The arctic archipelago of Svalbard is already experiencing dramatic effects from climate change. A new study shows how these changes can force wild reindeer to graze on seaweed, a strategy that increases their likelihood of survival— and is recorded in their poop.
Carbon capture is cheaper than ever
According to a new report, many years of research effort have resulted in significant reductions in the cost of full-scale carbon capture and storage.
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.
EU consumption results in high carbon emissions from tropical deforestation
A sixth of all emissions resulting from the typical diet of an EU citizen can be directly linked to deforestation of tropical forests. Two new studies shed light on this impact, by combining satellite imagery of the rainforest, global land use statistics and data of international trade patterns.
Gunnerus Award goes to expert on biodiversity
Ecology professor Sandra Myrna Díaz is the winner of the 2019 Gunnerus Award in Sustainability Science.
This solar panel is the first in the world to store both electricity and heat
Moreover, researchers have succeeded in increasing its output dramatically by providing the panel with its own cooling system.
Short-term hydro operation planning could bring in billions
What is the best timing for the various hydroelectric plants to produce power? NTNU and SINTEF have developed an efficient and profitable simulation tool to make the most of hydropower generation.
Could Trondheim be Norway’s new seabed mining capital?
Stavanger is Norway’s oil capital. Trondheim could become the country’s capital for seabed mining. It will be an important contribution to the UN’s climate goals.
Snake robot ready to go on watch in the deep seas
A snake robot will soon be relieving divers and mini-subs in the North Sea. But first researchers have to test its mettle in the Trondheim Fjord.
Danish-Norwegian Cooperation on Offshore Wind Expanded
Better and cheaper offshore wind farms are the goal for a new cooperative effort on renewable energy.
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.
Ocean acidification stimulates mass development of toxic algae
If carbon dioxide concentrations in the atmosphere and in the ocean continue to rise, this could fuel the mass development of toxic algae, with far-reaching consequences for the pelagic food web, an international team of researchers has found.
When the hum of insects disappears
Several countries are warning of massive insect deaths. Right now we don’t know how matters stand in Norway. But that’s about to change.
