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.
Energy and environment
Global warming and political decisions are opening the Arctic and its frosty seas to increased development. But what will happen if that expansion results in oil spills in the frozen ocean?
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.
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.
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.
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.
A remote field site in the Norwegian mountains is improving our understanding of carbon cycling in high-latitude alpine areas.
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.
Plastic trash is a rapidly growing environmental problem. But a biodegradable and natural material could replace plastic packaging and eliminate this problem.
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.
Research scientists are collaborating with industry to find ways of building wind turbines up to 200 metres high.
If 4,000 Norwegian farms and nurseries produced biochar and mixed it with the soil, we could halve CO2 emissions from the agricultural sector. This entirely natural approach also produces more robust and healthy plants.
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.
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”.
Carl Folke, a groundbreaking researcher in his field, has been awarded the Gunnerus Sustainability Science Award for 2017.
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.
A series of first-ever maps shows regional-scale differences in carbon footprints in the EU. The maps can help guide local and regional policies designed to cut greenhouse gas emissions.
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.
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.
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.
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.
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.
