Reuters report:
Shipping contributes about four percent of global emissions from burning fossil fuels, about double the emissions from aviation.
But the industry is less visible to most people than aviation and only very recently faced limits on some of the pollutants in funnel emissions, particularly nitrogen oxides (called NOx) and sulphur dioxide.
Just a few kilometres from one of the busiest ports in the world, a Singapore firm says it has the answer that can help the shipping industry clean up its act.
Ecospec says it has invented and tested a patented method that removes planet-warming carbon dioxide and nitrogen oxides, sulphur dioxide, which causes acid rain, and soot from ship exhausts.
Their process uses seawater with increased PH (10), sprayed in the exhaust funnel. The dirty water is cleaned before returning it to the sea.
It is only an end-of-pipe solution, but if there are few or none alternatives available……
