In 2003, the average traffic speed in central London was less than 14 km/h. The congestion charge improved the flow of traffic but also had unwanted effects.
Energy and environment
Everyone knows there’s just too much carbon dioxide in the atmosphere — and we’re heating up the planet at an unprecedented pace. In the latest episode of NTNU’s new English-language podcast, 63 Degrees North, we’ll what Norwegian researchers are doing to help address this problem.
New discoveries are making silicon production cleaner, and solar cells of the future will become even more environmentally friendly.
The polar night is dark — if you’re a person. But not if you’re a krill or a seabird or a fish. In the first episode of NTNU’s new English-language podcast, 63 Degrees North, learn how researchers discovered that there’s more than enough light in the polar night for the tiny creatures who live there.
More biofuels are needed to counteract climate change. But producing them shouldn’t diminish food production or wilderness areas. The solution may be to grow more grass on recently abandoned cropland.
Even though new hydropower dam developments are intended to provide green energy, they can drown areas that are rich in plant and animal species. But this kind of collateral damage can be limited by strategic site selection, a new study shows.
Barnacle geese in the Arctic have been on a diet. So many now migrate to northern breeding grounds that in some places there’s less food to go around. The good news is that it doesn’t seem to restrict their population growth — yet.
NTNU and SINTEF will be partners in the newly funded FME NorthWind research centre, which will develop competitive offshore wind farms within ten years.
The EU has awarded two million euros for research on how animals are coping with climate changes.
The 2020 ISI/Web of Science Highly Cited Researchers list includes seven researchers affiliated with NTNU. The list includes authors who have multiple articles ranked in the top 1 per cent by citation in their field over the last decade.
The Norwegian research organisation SINTEF will investigate whether rare earth element minerals contribute to pollution in costal areas. Research scientists from Norway, Denmark and Germany are taking part in the project.
Emissions from the production of materials like metals, minerals, woods and plastics more than doubled in 1995 – 2015, accounting for almost one-quarter of all greenhouse gas (GHG) emissions worldwide. Material efficiency needs to play a larger role in climate planning, a new report says.
The capture and storage of CO2, also known as CCS, from our waste is essential because this refuse is responsible for a large proportion or our cities’ greenhouse gas emissions. Moreover, the technology represents a relatively inexpensive abatement cost.
The great tit and other birds can adapt to changes in their food supply as a result of climate change, but they run into trouble if the changes happen too quickly.
Agriculture is eating into areas that are important in protecting some of the most biologically diverse places on the planet. Most of this new agricultural land is being used to grow cattle feed.
Dopamine can trigger feelings of happiness in humans. Water fleas that are exposed to dopamine-regulating substances apparently gain several advantages.
We often associate innovation with someone who invents something completely new. But innovation is also about improving and expanding on existing technology. One hundred and ten years of Norwegian engineering history provides plenty of examples.
Future offshore oil and gas fields are most likely to be “satellite developments” that are less expensive and emit less greenhouse gases than other fields because they do not require new production platforms. An innovative Norwegian computational tool called “Slug Capturing 2” is now enabling the design of longer pipelines that will allow many more fields to be developed as satellites.
Ten years ago, the Deepwater Horizon accident in the Gulf of Mexico killed eleven men and resulted in the largest accidental oil spill in history. Years of investigations concluded that the drilling crew missed critical warning signals that would have stopped the problem. A new analysis suggests that wasn’t the case.
CO2 emissions are generally recognized as something we need to avoid. Wouldn’t it be nice if we could just transform the CO2 into useful substances? Plasma technology has been proposed as a way to achieve this, and we have studied the feasibility of the concept from physical, chemical and economical points of view.
From 1 July, scientists from 14 institutions in six countries will be examining the opportunities and risks of ocean-based technologies for negative emissions.
“This is international recognition of her many years of efforts to promote smart and sustainable cities,” says Henrik Asheim, Norway’s Minister of Research and Higher Education.
