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?

Home offices continue to affect our travel patterns

When countries shut down during the pandemic, many people stayed home. Some replaced their old habits with new ones, either temporarily until society opened up again or continuing post-pandemic. What do these changes in habit mean for our travel patterns?

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.

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.

A minute sensor to the rescue

Ships, bridges and wind turbines can all be made safe using sensors that are just a few millimetres across. Researchers have borrowed the principle behind the technology from a vibrating guitar string.

In search of a smarter grid

The Norwegian government is committed to reducing greenhouse gas emissions by 55 per cent by 2030. This will involve dramatic changes to the electricity grid system.

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.

Why there is still hope for our planet

Is it too late to save our planet? Professor Jianguo Liu is the newest winner of The Gunnerus Award in Sustainability Science. He offers us some hope.
