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.

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.

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”.

Reveals the real greenhouse gas footprints of reservoirs

When hydropower reservoirs traps organic matter, it leads to higher local greenhouse gas emissions. But the emissions are not increased but displaced. A new tool calculates the real greenhouse gas footprints of reservoirs.

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.
