Wind propulsion systems provider Norsepower installed its Rotor Sail Solution to a Scandlines hybrid ferry in a matter of hours during a scheduled overnight stop.
The rotor sail is estimated to reduce emissions by 5% without compromising speed or voyage times.
With the current focus on alternative marine power sources, it’s easy to overlook the overwhelmingly dominant position of the internal combustion engine, or ICE, in marine propulsion. The marine two-stroke ICE is so well proven and so well established that it will continue to have a central place in ship propulsion for decades to come.
If demands for decarbonization in shipping are to be met, the question then becomes one of fuel: which fuels can be green enough, and available soon enough, to satisfy stricter emissions regulations, and how will engine makers adapt to the new norm of fossil-free fuel?
In the midst of economic shocks and border closures caused by the coronavirus pandemic, the Pacific region has yet again been ravaged by a Category 5 cyclone that left a trail of destruction across four Pacific island countries in a span of four days from April 5 to 8.
The economic toll from Cyclone Harold and the response to the coronavirus pandemic to Pacific economies is yet to be determined, but they have for sure rolled backed significant economic gains in these countries.
Daily global emissions of CO2 fell by 17% at the peak of the shutdown because of measures taken by governments in response to COVID-19, say scientists.
The most comprehensive account yet published says that almost half the record decrease was due to fewer car journeys.
But the authors are worried that, as people return to work, car use will soar again.
