New filter removes run-off chemicals

The filter will first be used to recover aircraft de-icing chemicals. In the future it will also be used in urban areas to remove environmental toxins, pollution and probably microplastics.

Envisioning a future where all the trees in Europe disappear

Global climate change is already affecting the globe, as demonstrated by the shrinking polar ice cap, melting glaciers and cities in the grips of longer, more intense heat waves. Now a team of researchers has conducted a radical thought experiment on how extreme land use changes could influence future climate.

New study estimates the carbon footprints of 13,000 cities

Many see cities as the new front lines of the climate change fight. Identifying the mayors and city councils in cities with the biggest carbon footprints, and the most power to make big changes, could mobilize a wave of reinforcements.

Capturing CO2 using heat pumps

Capturing the greenhouse gas CO2 from industrial processes such as cement manufacture is a demanding and therefore expensive exercise. However, by introducing a renewable powered heat pump in the capture system, the energy required to capture CO2 is reduced by three quarters.

Plastic in rivers and lakes a growing concern

Almost all research on plastic contamination in water systems focuses on oceans. But the biggest problem is plastic that ends up in freshwater ecosystems, according to an NTNU biologist.

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.

Preventing hurricanes using air bubbles

Many people have tried to find ways of preventing hurricanes before they make landfall, resulting in the loss of human lives. Norwegian researchers believe that the answer lies in cold bubbles.

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.

Land under water: Estimating hydropower’s land use impacts

One of the key ways to combat global climate change is to boost the world’s use of renewable energy. But even green energy has its environmental costs. A new approach describes just how hydropower measures up when it comes to land use effects.

Revealing the geology’s X-factor

This ten-tonne test rig has been custom-designed by Norwegian researchers and built under contract by American engineers. It has finally been installed at SINTEF after eight years of planning and construction. This mammoth of a device, nicknamed the “Polyax Rocker” is now set to re-create with ultra-high precision the geological stresses acting on oil reservoirs.

Our cities are hidden power stations

Waste heat and locally-produced renewable energy can be generated by compact, “urban power plants” that are efficient enough to supply heat to entire housing estates.

Consumer choices for the climate

The gift-giving season is upon us, and perhaps you’re wondering how to give gifts that won’t wreck the climate. Help is on the way.

Green gaming for the environment

Computer games designed to make us more environmentally conscious need to be both entertaining and educational. Few game designers are good at both. NTNU researchers are creating a model that can bridge the gap between the two.

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.
