The jewel in the crown

“Dynamic positioning” has been hailed as “the jewel in the crown” and Norway’s greatest engineering feat since World War II. But what is it?

Recycling aluminium, one can at a time

Producing pure aluminium from ore accounts for as much as 1 per cent of all greenhouse gas emissions worldwide. Recycling is the best way to reduce that carbon footprint – but manufacturers and recycling companies will have to plan carefully to avoid problems with impurities that accumulate in recycled aluminium over time.

Carving up the global carbon pie in a new way

When negotiators come to Paris this December to discuss a binding and universal agreement on controlling climate change, they have to know how much each country contributes to the greenhouse gas emissions problem. A new method offers the best hope yet for accurately accounting for these emissions by providing the right incentives and assigning fair responsibilities.

Predicting a safe lifetime for risers

More than 90 percent of Brazil’s petroleum reserves are found in deep water or ultra-deep water areas offshore. Researchers at SINTEF’s Brazil office are using advanced modelling and testing, including neural networks, to improve the lifespan and safety of a key component used to exploit these deep water reserves.

A Third Industrial Revolution for Norway

Norway’s wealth and prosperity over the last four decades has been built on oil, but Jeremy Rifkin, a futurist and social and economic thinker, says it’s time for the country to change. The Third Industrial Revolution is coming, and Norway needs to abandon fossil fuels and move towards a greener future that relies on renewable energy, shared transport and ultra-efficient housing.

Extreme weather in the Arctic causes problems for people, wildlife

The last week of January 2012 brought wild weather to the Norwegian arctic island archipelago of Svalbard and its largest town, Longyearbyen. A new cross-disciplinary study provides a comprehensive look at the effects of this extreme weather event on everything from town infrastructure to the natural environment.

Low-carbon electricity future is clean and feasible

The countries of the world wrapped up preliminary climate talks in Lima, Peru this weekend with an agreement on how the UN’s 194 countries will tackle climate change. The agreement comes in advance of major negotiations scheduled for Paris next year to designed to curb the world’s production of greenhouse gases. In a publication from earlier this year, researchers at NTNU’s Industrial Ecology Programme report that the low-carbon future that would result from curbing greenhouse gas emissions is both feasible from a practical standpoint, and will also substantially reduce air pollution.

Turning humble seaweed to biofuel

A Norwegian research group has been able to achieve bio-oil yields of 79% from a common kelp. Other researchers working with the same species have yields closer to 20%. The secret is to heat the kelp very quickly and bring it to the right temperature within seconds.

Hope for the climate, hope for clean air

Climate talks in New York this week have offered a glimmer of hope that the world’s political leaders finally understand the need to act to curb global warming. An NTNU researcher says that these actions will have a beneficial side effect: cleaner air in some of the most polluted places on the planet.

The Towing Tank turns 75

NTH, Norway’s first technical university and one of the main predecessors to NTNU, SINTEF and MARINTEK, opened in Trondheim in 1910. Just three years later its scientists began to think very big – 170 metres big.

We know that hormone mimics are harmful to us, and that they don’t break down naturally", says Per Stenstad.  They  accumulate in waste water and soil". Photo: Thor Nielsen.

Capturing false hormones

They damage our ability to reproduce, and they pollute the natural environment. Yet chemicals known as hormone mimics can be found in consumer goods. Eventually they end up in our water. But we now have a way of capturing them.

Monitoring neighbourhood electricity consumption

With more and more Norwegian households owning one or even two electric cars requiring charging overnight, how will we manage without sacrificing our hot morning shower and fresh bread for breakfast?

The secret life of the sea trout

Armed with special acoustic tags, a team of researchers is following 50 individual fish for as long as seven months to learn more about their life – and death — in Norwegian fjords.

What do we do when a well blows out?

Oil and gas companies are worried about gas discharges at the sea bed. Recent field experiments can now quantify the volumes of gas reaching the sea surface and how they spread in the atmosphere.

Celebrity ice

Not since the Titanic has a block of ice been quite so famous. In early June, Discovery Channel Canada came to NTNU’s Structural Impact Laboratory (SIMLab) to watch ice researchers from NTNU’s Sustainable Arctic Marine and Coastal Technology programme use a giant machine to simulate what happens when a ship slams into an iceberg.

Lopwood and brushwood make high-grade charcoal

When the forestry machines have finished extracting timber, what is left are tops and branches – waste which cannot be used. However, according to researchers, it is possible to turn these heaps of lopwood into high-quality charcoal.
