Tiny gold particles can help harness energy from the sun to break down pollution
Researchers at NTNU have found a way to make gold nanoparticles with a uniform size and shape, opening up the possibility of finding more effective photocatalysts

Mapping the conflict between farming and biodiversity
A new study provides the most detailed dataset yet on the biodiversity footprint of food. The results can lead to more sustainable diets.
Pupils are making circular art for Oslo’s first ‘energy-plus’ school
Recycling is the guiding principle behind the new Voldsløkka school and Culture Centre. Pupils are taking part in an art project as their contribution to the research project called ARV.
Data is just as important as the electricity we generate from the sun and wind
During his visit to Norway earlier this year, Bill Gates was keen to emphasise the innovation that will be needed to reduce the costs of mitigating climate change. One place to start is to educate more experts in the field of data processing.
Gaining a better overview of life on earth
Approximately 47 000 different species have been identified in Norway – and there are probably many more. A new tool can help us gain a better overview.
To avoid a battery crisis, more of us should share small, lightweight EVs
Fossil fuel vehicles gulp down petrol, and electric cars gobble up minerals. The battery industry is so ravenous for lithium as a raw material that researchers believe the demand could threaten climate goals.
150 hydrogen-powered trucks ready to roll on European roads
Haulage truck and fuel manufacturers have joined forces with researchers to make heavy transport across Europe more climate-friendly. And all thanks to having SINTEF ‘behind the wheel’.
There are easier ways of integrating solar power into the energy system
We need the electricity generated by solar panels in order to meet our climate change mitigation targets. But solar power must be integrated rationally and fairly – something that can only be achieved with effective regulation.
Tracking whales as they cruise the Arctic
For the first time ever, researchers have been able to track eight fin whales in near real time for five hours, as they swam along a stretch of fibre-optic cable line in the Arctic. The breakthrough suggests that fibre-optic cable networks could be harnessed to help prevent whale deaths by ship strikes.
Electric car batteries are difficult to recycle – at least for now
Electric cars are a growing market, and so are the large batteries they use. Often these batteries are difficult to recycle. But help is on its way.
Artificial intelligence could secure the power supply
Managing hydropower production is complicated. Artificial intelligence can help ensure that we don’t run out of power.
We know that carbon capture from the atmosphere is possible. But how do we get there?
Direct Air Capture (DAC) technologies offer new opportunities for getting closer to our climate change mitigation targets. However, we still have a long way to go before DAC can be fully rolled out as a mitigation measure.
Carbon capture using sunlight and mirrors
Researchers are planning a solar energy plant that will capture ‘concentrated sunlight’ using mirrors. The plant will also be distinctive because it will generate both electricity and heat, which can be used to capture carbon dioxide.
Snow-repelling solar cell panels could boost generation in Norway
Norway has seen an increase in solar power capacity in recent years, but in winter solar panels face a big problem: snow. Researchers modelled how much extra electricity could be generated if solar panel surfaces were designed to repel snow and ice.
Must we sacrifice nature to mitigate climate change?
The magnets in wind turbines come from China, and the materials in our electric car batteries are for the most part sourced from Congo. Today, key minerals and metals are being transported to Europe from politically unstable countries far away. Is it possible to safeguard access to these raw materials here in Norway? In this article, we present three research-based strategies for addressing the problem.
Yes, we should produce hydrogen in Norway
Producing hydrogen will become an important part of decarbonising Europe’s energy system and is one of the opportunities Norway has to maintain value creation along the lines of what the country has experienced with oil and gas.
Hydrogen from A to Z
Hydrogen is found in large quantities on Earth, can be used in many contexts and is being promoted as an important solution in the transition to climate-friendly energy. But hydrogen investment also generates heated debate. So what’s the deal with hydrogen?
What type of paths do we need to encourage more people to cycle all year round?
Even in Norway, more people than ever are cycling in winter. But what types of cycle paths are best for the cyclist, the bike, the path itself and the environment?
What exactly is the EU taxonomy?
Perhaps you’ve heard about it and are wondering exactly what the EU taxonomy is – and what it really means. SINTEF researcher Mathias Irgens is ready with an explanation.
For how long can you keep warm during a power outage?
Many Norwegian homes can only be heated using electricity. The authors of this blog argue that in the event of an extended power outage, energy-efficient homes will stay warm for much longer than those built according to the minimum regulatory requirements.
Nuclear power causes least damage to the environment
A comprehensive analysis of 870 power plants worldwide shows that nuclear power is a clear winner in protecting ecosystems. Bioenergy is a sure loser.
The ice in Antarctica has melted before
The ice sheet in Queen Maud Land in East Antarctica is not stable. Large amounts of ice have melted in the past, most recently as 5,000 years ago.
Prestigious EU support to save species
An NTNU professor has been awarded an ERC Advanced Grant to investigate how species can survive a changing environment.
An artificial lava for sealing oil and gas wells has passed its lab tests
Norwegian oil and gas companies are now plugging and abandoning production wells using an artificial ‘lava’. So far, the results have been excellent. Recent laboratory results indicate that the same method can be used to seal subsurface CO2 storage reservoirs.
