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.
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.
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.
New discoveries are making silicon production cleaner, and solar cells of the future will become even more environmentally friendly.
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.
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.
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.
“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.
NTNU researchers are playing a leading role in a new IPCC report. One way they’re helping is collecting data on a website created and operated by the university.
Chinese authorities are investing heavily in green energy. The country has become a world leader in solar and wind power. This rapid expansion was made possible by the approach taken by authorities.
Hydrogen as an energy carrier can help us move away from fossil fuels, but only if it is created efficiently. One way to improve efficiency is to use waste heat that’s left over from other industrial processes.
Norwegian scientists have developed a material which can make hydrogen from water vapor, instead of liquid water. It pays off, because heat is cheaper than electricity.
Combatting global warming will require major changes in land use, a new climate change report says. One important change could be decreasing the amount of land used to produce livestock — which means that people would have to eat less meat.
Climate frustration led three former NTNU students to quit their secure and well-paying jobs. Instead, they developed a digital toolbox for the green shift. Now the world is knocking on their door.
The boat wings started as an unfinished idea in Eirik Bøckmann’s head. Now they’re being mounted on a ferry in the Faroe Islands.
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 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.
Moreover, researchers have succeeded in increasing its output dramatically by providing the panel with its own cooling system.
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.
Our carbon emissions are much higher than are needed for us to have happy, healthy lives. But cutting these emissions requires us to think differently about how we measure growth and progress.
The countries of the world still need to cut their carbon dioxide emissions to reach the Paris Agreement’s climate targets. Relying on tree planting and alternative technological solutions such as geoengineering will not make enough of a difference.
Research on minerals and materials is important in helping society make the transition to a greener economy. NTNU, the Geological Survey of Norway and SINTEF have joined forces to establish a national laboratory to that end.
