Recirculating off-gas contributes to carbon capture
Producing silicon results in large carbon dioxide emissions, but recirculating it can remove contaminants more efficiently.

The Longship that could help save the planet
Everyone knows there’s just too much carbon dioxide in the atmosphere — and we’re heating up the planet at an unprecedented pace. In the third episode of NTNU’s new English-language podcast, 63 Degrees North, we’ll hear what Norwegian researchers are doing to help address this problem.
Abandoned cropland should produce biofuels
More biofuels are needed to counteract climate change. But producing them shouldn’t diminish food production or wilderness areas. The solution may be to grow more grass on recently abandoned cropland.
CCS during waste incineration removes CO2 from the atmosphere
The capture and storage of CO2, also known as CCS, from our waste is essential because this refuse is responsible for a large proportion or our cities’ greenhouse gas emissions. Moreover, the technology represents a relatively inexpensive abatement cost.
Losing ground in biodiversity hotspots worldwide
Agriculture is eating into areas that are important in protecting some of the most biologically diverse places on the planet. Most of this new agricultural land is being used to grow cattle feed.
Ocean-based negative emissions technology research receives prestigious funding
From 1 July, scientists from 14 institutions in six countries will be examining the opportunities and risks of ocean-based technologies for negative emissions.
From coronavirus to a greener society?
Governments across the globe are funding record-breaking crisis packages to cope with the economic fallout from the coronavirus pandemic. Is this the time to fund greener, more climate-friendly industries and investments?
If the world can capture carbon, there’s capacity to store it
Humankind will need to harness carbon capture and storage technologies to help keep global warming to 2 degrees C or less. New research shows that there’s plenty of room to store captured CO2 — in offshore geologic rock formations.
Testing CO2 transport on the laboratory roof
When scientists carry out experiments to investigate safe and efficient CO2 transport on the roof of the thermal power engineering laboratories at Trondheim, Norway, the noise they make will sound like a jet engine.
Water was a winner in capturing CO2
Reducing the level of CO2 in the atmosphere will probably require carbon capture. A surprising substance just might be the ticket.
This is what you need to know about CCS – Carbon Capture and Storage
Why is there so much talk about storing CO2 underground? Doesn’t it cost more than it’s worth? Here we provide the research scientists’ answers and explanations of why CCS is climate technology that we are completely dependent on. And yes, this can be performed in a safe manner.
Fewer cows, more trees and bioenergy
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.
These experiments are key to being able to store lots of CO2 safely in the subsurface
When energy researchers carry out experiments to investigate safe and efficient CO2 transport on the roof of the thermal power engineering laboratories at Gløshaugen, Trondheim, the noise they make will be like a jet engine.
Carbon capture is cheaper than ever
According to a new report, many years of research effort have resulted in significant reductions in the cost of full-scale carbon capture and storage.
Making it easier to capture CO2 in the cement industry
Cement manufacture accounts for as much as seven per cent of global greenhouse gas emissions. A new hybrid technology makes it easier and less expensive to capture and purify CO2 produced by the industry. And the technology can be retrofitted to existing plants.
What does sheep grazing do to the mountains?
Livestock grazing affects the landscape. What effects does it have on the vegetation?
Geoengineering, other technologies won’t solve climate woes
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.
Capturing CO2 using heat pumps
Capturing the greenhouse gas CO2 from industrial processes such as cement manufacture is a demanding and therefore expensive exercise. However, by introducing a renewable powered heat pump in the capture system, the energy required to capture CO2 is reduced by three quarters.
Your wood stove affects the climate more than you think
Fortunately, a new study indicates that heating with wood has a cooling effect.
Meadows beat out shrubs when it comes to carbon storage
A remote field site in the Norwegian mountains is improving our understanding of carbon cycling in high-latitude alpine areas.
This ingenious approach not only binds CO2, but also improves the soil
If 4,000 Norwegian farms and nurseries produced biochar and mixed it with the soil, we could halve CO2 emissions from the agricultural sector. This entirely natural approach also produces more robust and healthy plants.
Destination Brussels – with climate facts in his luggage
SINTEF’s climate change ambassador Nils Røkke is on his way to Brussels looking forward to a new job and new assignments. He has been appointed as Chair of the European Energy Research Alliance (EERA). This in a world in which the threats posed by climate change are increasingly being portrayed as “fake news”.
Finding life — and farming minerals — deep under the sea
Japanese researchers have access to the largest scientific vessel ever constructed, one that has a 120 metre tall derrick capable of drilling to 7500 metres below the seafloor. They’re using it to hunt for life deep under the seafloor and explore for mineral deposits at the bottom of the ocean — topics that are of great interest to Norwegian researchers.
– The world doesn’t realise how much we need CO2 storage
The world will not be able to reach the goals of the Paris Agreement without technology capable of capturing, transporting and storing CO2.
