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.
Energy and environment
“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.
We’ve changed our name to Norwegian SciTech News — so readers know immediately what they will find here.
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.
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.
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.
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.
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.
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.
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.
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.
Ecology professor Sandra Myrna Díaz is the winner of the 2019 Gunnerus Award in Sustainability Science.
Moreover, researchers have succeeded in increasing its output dramatically by providing the panel with its own cooling system.
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.
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.
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.
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.
Climate change in the Arctic means more winter rain, and consequently more rain falling on snow. The result can be a buildup of ice under the snow, which can wreak havoc with arctic ecosystems.
Cement manufacture accounts for as much as seven per cent of global greenhouse gas emissions. A new hybrid technology makes it easier and less expensive to capture and purify CO2 produced by the industry. And the technology can be retrofitted to existing plants.
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.
