Abandoned cropland should produce biofuels

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.

Smart site selection can make hydropower greener

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.

Skinnier but resilient geese thriving in the high Arctic

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 researchers among the world’s most highly cited

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.

Using materials efficiently can substantially cut greenhouse gas emissions

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.

Losing ground in biodiversity hotspots worldwide

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.

110 years of engineers who built Norway

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.

Simulation model may reduce the climate footprint of oil production

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.

New lessons from the worst oil spill disaster ever

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.

How a Plasma Gasifier Can Reduce CO2 Emissions

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 coronavirus to a greener society?

Governments across the globe are funding record-breaking crisis packages to cope with the economic fallout from the coronavirus pandemic. Is this the time to fund greener, more climate-friendly industries and investments?

Global supply chains as a way to curb carbon emissions

The coronavirus outbreak raised everyone’s awareness of the significance of global supply chains to modern economies. But global supply chains also play an important role in greenhouse gas emissions. How they are managed can either increase or decrease carbon emissions, new research shows.
