BUNKER FUEL HEAVY OILS

CLEANER TERMINALS - Quite a few ports are now building LNG terminals for cargo ships and oil tankers to ply the waves with lower emissions.
Bunker Fuel is a heavy low grade oil that is high in sulphur content and is now being phased out for marine transport due to marine anti-pollution (MARPOL) requirements.
We are now seeing cleaner ships being built that operate on Liquid Natural Gas (LNG) that is much cleaner burning but is of course still a carbon dioxide and nitrogen oxide polluter, hence, is still a global warming risk adding to climate change.
What we need is zero carbon shipping, like the Elizabeth Swan or SeaVax ocean cleaning workhorses that we hope will one day come to fruition.
Fossil fuels kick started our industrial revolution, powered steam ships and generated electricity as we released the energy in coal and later oil, to make things happen at a faster pace. Cars and aircraft being an example of things we now take for granted that pollute big time.
But it was a brilliant time for engineers and town planners who thought they could rely of this energy source without any consequences. Because after all the world is a big place. Surely humans could not alter the delicate ecological balance of planet earth just by driving a few cars and lighting a few home fires. Then came central heating. Sh*#%
Sadly, we can. We did and we still are, even though we now know how dangerous our excesses are to other species - and we are also set for extinction if we do nothing to swap fossil fuels for clean renewable energy sources.
