Exhausting Our Green Shipping Options

Shipping is currently responsible for approximately 3 million tons of sulphur dioxide emissions, 4.5 million tons of nitrogen dioxide emissions and 900 million tons of greenhouse gas emissions yearly. (Credit: Agency for Science, Technology and Research) Click to Enlarge.
Scientists in Singapore have developed a revolutionary emissions abatement system that removes pollutants from exhaust gas to help the international shipping industry meet ambitious emissions targets.

In 2013, the International Maritime Organization (IMO) introduced new regulations to reduce exhaust emissions attributed to the shipping industry.  Shipping is responsible for around 90% of global trade and the effect of reducing emissions such as sulphur oxides (SOx), nitrous oxides (NOx), particulate matter and greenhouse gases such as carbon dioxide (CO2) will have a huge impact on global totals.

Researchers from the Agency for Science, Technology and Research Institute of High Performance Computing (IHPC) together with Sembcorp Marine Ltd and Ecospec Technology Pte Ltd have risen to the challenge of finding ways to meet the IMO's new emissions targets.

The team from Sembcorp Marine Ltd and Ecospec Technology Pte Ltd has developed an exhaust gas treatment system, called cSOx, which removes SOx and CO2 from ships' diesel engine and boiler exhaust emissions.  It uses ultra-low-frequency electromagnetic waves to treat seawater, thereby optimizing the system's ability to absorb sulfur dioxide and CO2.
