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.

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.

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 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.

Builders rush to learn from the ZEB lab showcase

The ZEB Laboratory has been utilised both as an office building and a sustainable construction laboratory for about two years. It was designed to be the world’s most ambitious ‘climate-adapted building’ and up to now it has been a great success.

Moose can play a big role in global warming

Climate researchers have long known that large animals, like moose, could play a role in how much the Earth will warm due to climate change. But the question is, how much? New research shows the answer can be a lot.

New concrete from old buildings

Christian John Engelsen at SINTEF is teaching the world to recycle demolition rubble to make new concrete. Anything and everything can be recycled, he says. What takes time is getting people on board.
