AP Møller-Maersk has contracted for 19 methanol dual-fuelled container ships (supply: Maersk)

Decarbonisation and environmental laws such because the Carbon Depth Indicator (CII) will proceed to drive fleet renewal selections by vessel house owners in 2023, with LNG, methanol and batteries among the many power sources they embody of their investments
What follows are the highest 5 traits in marine propulsion in 2023, in accordance with Marine Propulsion editor John Snyder.
Banner 12 months for LNG
2022 was a banner 12 months for LNG as a gas and the uptake of other fuels methanol, hydrogen and ammonia as a complete. Of all of the ships ordered throughout 2022, barely greater than 22% will probably be able to burning various fuels, 200 of those – about 73% – of that are LNG-fuelled vessels. Knowledge compiled by DNV suggests this ordering spree has pushed the overall world fleet of LNG-fuelled vessels to 857, some 338 of that are in operation – a testomony to the gas’s CO2 and greenhouse gasoline discount traits, widespread availability and the more and more accessible LNG bunkering footprint. A few of the essential drivers in 2023 for LNG gas would be the continued growth of bunkering infrastructure, work on methane slip and wider availability of bioLNG.
Methanol momentum continues
Subsequent 12 months brings with it the much-anticipated debut of Maersk’s 2,100-TEU carbon-neutral, methanol dual-fuel feeder ship. The comparatively small liner carries huge expectations for AP-Møller-Maersk and for the trade as a complete. The Danish shipowner has ordered 19 methanol dual-fuel container ships, and reduce 9 offers to attempt to safe inexperienced methanol availability for its ships, the newest two being with US-based mission developer Carbon Sink and SunGas Renewables. Moreover, the carbon-neutral field ship will underpin the creation of a Inexperienced Hall within the Baltic.
Maersk’s guess on methanol in 2021 appeared to behave as a beginning gun for different shipowners to ignite their decarbonisation engines with methanol. Over the subsequent two years, the worldwide methanol-fuelled fleet will develop by 250% to 56 vessels.
Methanol made important in-roads in 2022 into different vessel segments, most notably offshore. The orderbook for methanol dual-fuel vessels stood at 60 as of mid-December, in accordance with DNV Different Fuels Perception. As is the case with LNG, methanol is a fossil gas providing speedy CO2 and greenhouse gasoline emissions reductions, with mature engine expertise accessible and operational expertise. Orders for methanol-fuelled vessels will proceed into 2023.
Extra dual-fuel engine expertise to the rescue
Decarbonisation would come to a standstill with out speedy developments in two- and four-stroke engine expertise. Engine designers have stepped as much as the decarbonisation problem, pouring sources to underpin and speed up the transition to the brand new low- and zero-carbon fuels methanol, hydrogen and ammonia.
2023 will deliver a number of new dual-fuel engine platforms from main two-stroke and four-stroke marine engine producers – too quite a few, the truth is, to call test right here. That in and of itself is welcome information to vessel house owners and shipbuilders alike.
Mitigating methane slip
Not counting the LNG provider phase, LNG as a marine gas has been used for barely greater than twenty years, beginning with the 2000-built Norwegian automotive ferry Glutra. What’s going to additional underpin the expansion of LNG gas in transport is the discount of methane slip – basically unburnt gas launched into the environment within the combustion course of. Methane is a strong greenhouse gasoline, with a worldwide warming potential of 27-30 instances CO2 over a 100-year interval, in accordance with the EPA. Engine designers are already targeted on clamping down on methane slip; higher combustion, higher environmental profile and higher gas consumption. Moreover, search for additional developments similar to methane oxidation catalysts.
Electrifying alternatives
Advances in maritime battery expertise proceed, with battery producers and propulsion system integrators remaining busy all through 2022. There’s no cause to assume 2023 will deliver something however good tidings to all of them as elevated learnings and system growth continues. The maritime battery market is anticipated to develop to US$10Bn by 2030, and subsequent 12 months ought to see extra batteries put in in OSVs, ferries and tugs.
