Inside the ice caves on Svalbard

Svalbard’s cold climate means that its glaciers are solid and frozen to the ground. This allows for winter travel into unique ice caves that contain plants and material that froze into the glacial ice as it formed.

Svalbard’s electric power 
could come from hydrogen

Longyearbyen, the world’s most northerly city, could save more than 100 million kroner (11.5 million US dollars) a year in the cost of electricity, if a completely green hydrogen-fuelled power station is built in preference to laying a cable from the mainland, according to calculations made by SINTEF scientists.

A future for skiing in a warmer world

As the world struggles to make progress to limit climate change, researchers are finding ways to adapt to warmer winter temperatures — by developing environmentally friendly ways of producing artificial snow.

One radiator to heat a whole floor

What happens to people’s comfort level when the heating system in a super-insulated building is simplified by installing only one radiator per floor?

The magical reindeer nose

Every schoolchild knows about Rudolph the Reindeer and his magic red nose. But Rudolph’s real-life counterparts really do have a magic nose. The colder it is, the better it is in keeping the animals warm and hydrated.

Speed warning system saves lives and reduces emissions

Universal adoption of the ISA speed warning system in Norway could reduce both the average speed of vehicles and their emissions, concludes a recent SINTEF report. Lower speeds also lead to fewer fatalities and serious injuries on the roads.

Energy savings in shopping centres

Shopping centres are major energy consumers with significant opportunities for savings. Researchers are currently checking the impact of savings made on lighting and air-conditioning at the City Syd centre in Trondheim.

Global hot spot maps link consumers with impacts

A new model creates global hot spot maps to illuminate how what we buy pollutes the planet and where. The idea is to help governments, industries and individuals target areas for cleanup.
