Hydrogen as an energy carrier can help us move away from fossil fuels, but only if it is created efficiently. One way to improve efficiency is to use waste heat that’s left over from other industrial processes.
Norwegian scientists have developed a material which can make hydrogen from water vapor, instead of liquid water. It pays off, because heat is cheaper than electricity.
Combatting global warming will require major changes in land use, a new climate change report says. One important change could be decreasing the amount of land used to produce livestock — which means that people would have to eat less meat.
Climate frustration led three former NTNU students to quit their secure and well-paying jobs. Instead, they developed a digital toolbox for the green shift. Now the world is knocking on their door.
The boat wings started as an unfinished idea in Eirik Bøckmann’s head. Now they’re being mounted on a ferry in the Faroe Islands.
We need to cut both global and local emissions from shipping. The picture is complex, but research is showing that there are many ways to meet this goal.
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.
Moreover, researchers have succeeded in increasing its output dramatically by providing the panel with its own cooling system.
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.
Our carbon emissions are much higher than are needed for us to have happy, healthy lives. But cutting these emissions requires us to think differently about how we measure growth and progress.
The countries of the world still need to cut their carbon dioxide emissions to reach the Paris Agreement’s climate targets. Relying on tree planting and alternative technological solutions such as geoengineering will not make enough of a difference.
Research on minerals and materials is important in helping society make the transition to a greener economy. NTNU, the Geological Survey of Norway and SINTEF have joined forces to establish a national laboratory to that end.
Ships with wings? Researchers are piloting this NTNU-spawned technology on new coastal cruise ships now being tested in Trondheim. The wings – or foils – use less fuel and make the journey more comfortable for passengers.
Thanks to toxin-free technology that also saves energy, Norwegians can eat their ice cream without worrying about the climate.
Soon the prototype for the world’s first driverless electric passenger ferry will be ready to launch in Trondheim.
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.
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.
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.
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.
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.
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.
