Is methanol the future of maritime fuels?

It’s not a secret anymore that the shipping industry today is facing some serious challenges with respect to meeting upcoming exhaust gas emissions regulations. The contribution from shipping to sulphur oxide (SOx) and nitrogen oxide (NOx) emissions today is considerable, thus the need for reductions. Three main alternatives – switching to low-sulphur fuels, installing exhaust after-treatment devices, e.g. scrubbers, or using natural gas – have been investigated to some extent, but very little information is available on methanol as a marine fuel.Methanol is a clean fuelMethanol does not contain sulphur. Emissions of particulate matter and NOx from methanol combustion in marine engines are expected to be lower than those resulting from the combustion of conventional fuels. Methanol is widely available, can be safely transported and distributed using existing infrastructure, and in 2012 it is currently much cheaper than marine distillate fuel based on energy content.

Refineries May Foil IMO Aims to Cut SOx Emissions in Exhaust Gas

'Refiners threaten anti-pollution efforts in shipping', blared the caption of a Reuters article by correspondents Kan and Fabi on 17, January 2011, then coincidentally, came news a couple of days later that Wärtsilä was to retrofit the Containerships Vll, 13,995 dwt,  (owned by Helsinki based Containerships Ltd. OY) with their diesel engine exhaust-gas scrubber. Wärtsilä's first ever installation of a commercial marine scrubber (to serve their W7L64 main diesel engine) is intended to enable the ship to meet impending targets for reduced exhaust gas emissions of SOx in Emission Control Areas's while continuing to burn diesel fuel with sulfur content above the set limits. Containerships Vll: Photo Credit, Jens Boldt Bunkers With Minimal Sulfur to Become Scarce? Experts in the field pronounce that SOx emissions in diesel engine exhaust gas‚ which mostly comprise sulphur dioxide with a small amount of sulphur trioxide‚ are a function of the amount ... [More]
