Norwegian scientists will teach Europe to make snow

Trondheim: Norwegian researchers believe that it will be possible to make environmentally-friendly snow at above-zero temperatures. Now they have the backing of Europe and the skiing industry in their bid to save the sport from climate change.

Destination Brussels – with climate facts in his luggage

SINTEF’s climate change ambassador Nils Røkke is on his way to Brussels looking forward to a new job and new assignments. He has been appointed as Chair of the European Energy Research Alliance (EERA). This in a world in which the threats posed by climate change are increasingly being portrayed as “fake news”.

Living with zero-emission technology

How does technology change people, and how do people change in response to technology? Sixteen people volunteered to live in a high-tech, zero-emission house to help researchers answer those exact questions.

Fuel of the future

Heavy-duty trucks will soon be driving around in Trondheim, Norway, fuelled by hydrogen created with solar power, and emitting only pure water vapour as “exhaust”. Not only will hydrogen technology revolutionize road transport, it will also enable ships and trains to run emission-free.

An energy-efficient cleaning robot

State-of-the-art solar cells are efficient – but are even more so when they are kept clean. A cleaning robot developed by Norwegian researchers enables solar panels to deliver at full capacity.

Climate change, ocean diversity and women in science

Science has made great strides since Svante Arrhenius, the Swedish Nobel Laureate who in 1896 first determined that carbon dioxide from human activity could warm the planet. The same progress hasn’t been made in increasing the number of women in the sciences.

Stinky city air as climate art

Imagine breathing polluted New Delhi air. It’s a scorching 40 degrees and the humidity is high. But you’re not in New Delhi – you’re in an art installation, during the Starmus festival in Trondheim in June.

Finding life — and farming minerals — deep under the sea

Japanese researchers have access to the largest scientific vessel ever constructed, one that has a 120 metre tall derrick capable of drilling to 7500 metres below the seafloor. They’re using it to hunt for life deep under the seafloor and explore for mineral deposits at the bottom of the ocean — topics that are of great interest to Norwegian researchers.

Does ‘green energy’ have hidden health and environmental costs?

Production of electricity is responsible for about a quarter of global greenhouse gas emissions, and demand is poised to rise as underserved populations connect to the grid, and electronics and electric vehicles proliferate. So stopping global warming will require a transformation of electricity production. But it is important to avoid various environmental pitfalls in this transition, researchers say.

Norway’s oldest ice found in Jotunheimen

Some of the ice in the Juvfonne glacier in Jotunheimen National Park in central Norway has been dated to be 7600 years old, currently the oldest dated ice on mainland Norway.

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.

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?

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.

Using EV tyres to counter traffic noise

Research shows that fitting tyres with very low rolling resistance, combined with the right road surfacing, can provide just as much noise reduction as traditional noise barriers.
