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?

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.

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.

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.

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.

The 80 per cent solution

By recycling used water, we can live with just a couple of buckets of fresh, clean water a day, while the rest of our water will come from recycled sources.
