Greener shipping in North America

A new report by DNV suggests that liquid natural gas (LNG) is the most efficient and economical way to meet air emissions requirements in the US and Canada that come into effect in August 2012, when the combined SOx and NOx Emission Control Area (ECA) along the North American coastline enters into force.

According to DNV, constructing a ship for LNG use ship may add about US$3.6 million to the cost of a typical domestic cargo ship. But over the operating life of the vessel, at today’s gas rates, LNG fuel would save more than US$4 million over scrubbers and US$12 million over low-sulphur distillate fuel.

Specifically, the use of LNG fuel instead of fuel oil would practically eliminate emissions of sulphur dioxide and particulate matter, reduce nitrogen oxides emissions by 85-90 per cent, and cut greenhouse gas emissions by 15-20 per cent.
