Long-houl shipping at sea

Ammonia – the key to making long-haul shipping green

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.

Retrofitting dams for more renewable energy in the world

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.

Researchers to test a solar farm at sea

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.

Engineering materials for a new generation of electronics

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.

WITH PODCAST

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.

Smart site selection can make hydropower greener

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 researchers among the world’s most highly cited

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.

Using materials efficiently can substantially cut greenhouse gas emissions

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.

110 years of engineers who built Norway

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.

Searching for the secret to more efficient solar cells

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.

New lessons from the worst oil spill disaster ever

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.

How a Plasma Gasifier Can Reduce CO2 Emissions

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.
