Sun and wind in a box

Renewable energy is fine, but often it’s needed at times other than when the wind is blowing or the sun makes an appearance. The energy needs to be stored – and a new method is on the horizon.

Gas instead of coal is 50% better for the climate

We can do a lot to save the climate by switching from coal to natural gas. And we can shelve concerns about the negative climate impact of methane emissions from gas production, say researchers.

When the Chinese giant awakes

When China sets its sights on a goal, the country can change at a blindingly rapid pace. Now the country is focused on innovation and technological innovations, with renewable energy at the forefront.

Measuring devices for the world’s most extreme environment

Norwegian research scientists are contributing to the development of the world’s hottest geothermal well in a non-volcanic area. The goal is to exploit the inexhaustible supply of heat from the interior of the Earth, and this calls for equipment that can withstand the most extreme conditions.

How well do solar cells really work in the Nordic climate?

Experiments in SINTEF’s climate lab demonstrate that solar cells work very effectively in Norway in spite of the rain and cold. But there is one thing that owners should be aware of if they want to get the most from the sun’s energy.

One hundred years of producing energy — from water

The 1969 discovery of oil at the Ekofisk field in the North Sea transformed Norway into an internationally important energy nation. But long before black gold was being pumped from the Norwegian Continental Shelf, Norway’s economy was fuelled by a different kind of energy: hydropower.

Controlling problem ice — by cracking it

Most efforts to control ice build-up on structures like wind turbines and solar cells involve creating a surface that repels water. But Norwegian researchers have engineered a different approach that allows ice to form on a surface, but then causes it to crack off.

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.

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.

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.

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.

ABC — anything but coal

Policymakers, industry and government officials will have to invest US $2.5 trillion for electricity generation over the next 20 years. A new report presents the environmental costs and benefits linked to different renewable energy sources, and makes one thing abundantly clear: anything is better than coal.

Two tickets to Paris to talk about carbon cuts

NTNU was given only two admission tickets to the UN climate talks in Paris later this month. The tickets will be used in part by two researchers from the university’s Industrial Ecology Programme to give a workshop about carbon accounting.

Timing is everything for renewable energy use

There’s no time to waste in shifting to renewable energy sources if we are to avoid dangerous climate change. That’s especially true when it comes to bioenergy, which causes a temporary increase in CO2 levels that is later removed as replacement biostocks grow.

Going for a geothermal world record

In Italy, researchers and drilling technologists are on the verge of making a geological breakthrough. They’re drilling deep enough to find what they call ‘supercritical’ water. If they succeed it will be a major technological breakthrough.
