Building with new thinking and old components

An old building at Tullinløkka in Oslo has set a new standard for reuse, consisting of components from other buildings – like concrete floor dividers from a government building. Building stock in Norway accounts for half of society’s total environmental impact. Thinking in new ways and reusing building components offers multiple gains.

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.

Kurobe dam

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 modelling a floating solar farm

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.

A robotic microplankton sniffer dog

The microscopic, free-floating algae called phytoplankton — and the tiny zooplankton that eat them — are notoriously difficult to count. Researchers need to know how a warming climate will affect them both. A new kind of smart, lightweight autonomous underwater vehicle (LAUV) can help.

Developing the world’s ‘hottest’ heat pump ever

Researchers working with industrial partners have developed the world’s first heat pump producing temperatures of up to 180 degrees celcius. Such record high temperatures will enable one fifth of European industry to reduce its energy consumption by up to 70 percent, and become entirely climate neutral.

Geiranger Fjord World Heritage site

Green quay will provide a green fjord

Big things might be happening soon with cruise traffic in the Geiranger fjord. Smaller vessels and adapted green quay facilities could make for a green fjord and offer a solution for preserving the World Heritage site.

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.

Shedding light — on the polar night

The polar night is dark — if you’re a person. But not if you’re a krill or a seabird or a fish. In the first episode of NTNU’s new English-language podcast, 63 Degrees North, learn how researchers discovered that there’s more than enough light in the polar night for the tiny creatures who live there.

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.

a gaggle of barnacle geese

Skinnier but resilient geese thriving in the high Arctic

Barnacle geese in the Arctic have been on a diet. So many now migrate to northern breeding grounds that in some places there’s less food to go around. The good news is that it doesn’t seem to restrict their population growth — yet.
