Air could be the world’s next battery

Storing compressed air in sealed tunnels and mines could be a way of storing energy in the future – if an EU project in which Norway is a partner is successful.

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.

Crushing ice to save platforms

It’s been a warm winter on Svalbard this year. But this doesn’t apply to the laboratory where Niek Heijkoop works. There it’s a stable -10° Celsius

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.

Green cooling with CO2

Man-made refrigeration gases threaten the Earth’s climate. The use of natural compounds like CO2 is an effective counter-measure.

Researching the dark side of microplastics

Minute particles of plastic, called microplastics, are everywhere. An international research team is now about to investigate how toxic microplastics are to marine animals such as plankton, crabs and fish, and to find out if such plastics accumulate in the food chain.

Trapping the sun’s energy—in a box

Planning on cooking something at your hut? Today, you still need a gas stove to do so. But soon, stoves and ovens containing rechargeable heat batteries may be readily available for any cabin or home.

Helping today’s power companies anticipate tomorrow

It’s not easy for big, profitable companies to respond to huge technological changes. One NTNU researcher hopes to help Norway’s electric power industry cope with the market challenges from renewable energy and changed consumer behaviour.
