Large cost cuts are achievable for both floating and bottom-fixed wind farms in the future. If we do this correctly, floating wind turbines will be able to compete with bottom-fixed wind turbines by 2030.
Relatively simple adaptation could make the cargo ships of the future completely green. The technology is based on the chemical compound ammonia, some extensive number crunching and one or two engine modifications.
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.
The sun shines just as much out at sea as it does on land. There are also no restrictions on area use and seawater even helps to cool the solar panel technology. It’s only a matter of time before the first floating solar energy farms are installed at sea.
Researchers have studied the energy consumption of 140 hotels in Norway and Sweden. The use of CO2 heat pumps could cut energy consumption in these hotels by about 60 per cent.
Solar cells that use special dyes to collect light could one day be integrated into buildings. Researchers at NTNU are trying to find the best dyes for the job.
Harnessing a fundamental property of electrons called spin could help create a new generation of computer chips and faster, more stable and less power hungry devices. NTNU researchers are studying a type of material that could make this technology feasible.
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.
New discoveries are making silicon production cleaner, and solar cells of the future will become even more environmentally friendly.
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.
Even though new hydropower dam developments are intended to provide green energy, they can drown areas that are rich in plant and animal species. But this kind of collateral damage can be limited by strategic site selection, a new study shows.
NTNU and SINTEF will be partners in the newly funded FME NorthWind research centre, which will develop competitive offshore wind farms within ten years.
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.
The Norwegian research organisation SINTEF will investigate whether rare earth element minerals contribute to pollution in costal areas. Research scientists from Norway, Denmark and Germany are taking part in the project.
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.
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.
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.
A new discovery is an important step towards smaller, more advanced electronics. And maybe more environmentally friendly gadgets, too.
Researchers hope to help with more efficient energy storage to increase the use of renewable energy.
The search for the perfect solar cell is not yet over. Norwegian researchers are now adopting a new approach to the cells’ raw material, crystalline silicon, with the aim of making the electricity-generating cells even more efficient.
Ten years ago, the Deepwater Horizon accident in the Gulf of Mexico killed eleven men and resulted in the largest accidental oil spill in history. Years of investigations concluded that the drilling crew missed critical warning signals that would have stopped the problem. A new analysis suggests that wasn’t the case.
CO2 emissions are generally recognized as something we need to avoid. Wouldn’t it be nice if we could just transform the CO2 into useful substances? Plasma technology has been proposed as a way to achieve this, and we have studied the feasibility of the concept from physical, chemical and economical points of view.
“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.
The coronavirus outbreak raised everyone’s awareness of the significance of global supply chains to modern economies. But global supply chains also play an important role in greenhouse gas emissions. How they are managed can either increase or decrease carbon emissions, new research shows.
