New solar panels from solar panel waste 

Solar energy is good news for planet Earth – but solar panels are not as climate-friendly as they should be. Researcher Martin Bellmann is using what he calls the ‘black gold’ waste materials from solar panel manufacture to make new panels. 

‘Bio-batteries’ enable us to store solar and wind energy

Up until now it has been a challenge to store the energy we generate when the sun is shining and the wind is blowing. But researchers at a laboratory in Trondheim in Norway have succeeded in doing just this – and entirely without any form of advanced battery technology.

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.

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.

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.

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.

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.
