Thousands of environmental bombs under Norwegian homes

Heating with oil in homes and commercial buildings is now banned in Norway. The storage tanks are supposed to be removed from buildings, but many people choose not to get rid of these environmental time bombs.

Could this dry battery system be Elon Musk’s next big thing?

The idea behind batteries is to make the planet greener, but they all start their lives as energy-demanding environmental liabilities. Research scientists at SINTEF have succeeded in making batteries cheaper and simpler using a process that requires much less energy consumption.

First ones out to buy and sell neighbourhood electricity

Many buildings with solar cells produce more electricity than they consume themselves, but current legislation prevents surplus power from being sold to neighbouring consumers. A pilot project in Trondheim will be the first in the world to test a system that makes this possible.

Resycling of phosphorous at Hias, Norway

Recovering eco-friendly phosphorous from wastewater

A shortage of phosphorous is driving the price of artificial fertilisers through the roof. But a new and eco-friendly wastewater decontamination process has enabled a company in Hamar in Norway to kill two birds with one stone.

Nature’s colours can replace toxic pigments

Dye pigments are often toxic, so researchers around the world have long been looking for effective ways to make non-toxic, recyclable and sustainable colours instead. The answer lies in nanotechnology and nature’s own methods.

ERC grant on food sustainability in China

NTNU researcher Marius Korsnes has been awarded an ERC Starting Grant from the European Research Council (ERC) . He will explore the concept of “sufficiency” when it comes to urban, sustainable food.

Is green growth possible?

Increases in economic growth contribute to one-for-one increases in carbon emissions. Energy system decarbonization and economic productivity gains are the most effective carbon emissions mitigation mechanisms for sustainable economic development.

What is nature worth?

Climate change is not the greatest threat to the diversity of species on Earth. The main problem is that animal and plant habitats are disappearing.

CyborGoats find their way into Norwegian villages

Goats are smart animals. A new technology takes advantage of their intelligence — so they longer need physical fences. More than 2400 Norwegian farmers are already using the technology to herd their animals.

Building with new thinking and old components

An old building at Tullinløkka in Oslo has set a new standard for reuse, consisting of components from other buildings – like concrete floor dividers from a government building. Building stock in Norway accounts for half of society’s total environmental impact. Thinking in new ways and reusing building components offers multiple gains.

Kurobe dam

Retrofitting dams for more renewable energy in the world

Many of the world’s dams are not used for hydropower, but a new study shows they could be easily altered to produce renewable energy. This would be the most sustainable solution for new energy production in the world, says NTNU Professor Tor Haakon Bakken.

Developing the world’s ‘hottest’ heat pump ever

Researchers working with industrial partners have developed the world’s first heat pump producing temperatures of up to 180 degrees celcius. Such record high temperatures will enable one fifth of European industry to reduce its energy consumption by up to 70 percent, and become entirely climate neutral.
