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 vitality sources they embrace of their investments
What follows are the highest 5 traits in marine propulsion in 2023, in response to Marine Propulsion editor John Snyder.
Banner yr for LNG
2022 was a banner yr for LNG as a gasoline and the uptake of different fuels methanol, hydrogen and ammonia as an entire. Of all of the ships ordered throughout 2022, barely greater than 22% can be able to burning different fuels, 200 of those – about 73% – of that are LNG-fuelled vessels. Knowledge compiled by DNV suggests this ordering spree has pushed the entire international fleet of LNG-fuelled vessels to 857, some 338 of that are in operation – a testomony to the gasoline’s CO2 and greenhouse gasoline discount traits, widespread availability and the more and more accessible LNG bunkering footprint. Among the essential drivers in 2023 for LNG gasoline would be the continued growth of bunkering infrastructure, work on methane slip and wider availability of bioLNG.
Methanol momentum continues
Subsequent yr 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 an entire. The Danish shipowner has ordered 19 methanol dual-fuel container ships, and minimize 9 offers to attempt to safe inexperienced methanol availability for its ships, the newest two being with US-based challenge 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 vital 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 response to DNV Various Fuels Perception. As is the case with LNG, methanol is a fossil gasoline providing rapid CO2 and greenhouse gasoline emissions reductions, with mature engine know-how accessible and operational expertise. Orders for methanol-fuelled vessels will proceed into 2023.
Extra dual-fuel engine know-how to the rescue
Decarbonisation would come to a standstill with out speedy developments in two- and four-stroke engine know-how. Engine designers have stepped as much as the decarbonisation problem, pouring assets to underpin and speed up the transition to the brand new low- and zero-carbon fuels methanol, hydrogen and ammonia.
2023 will convey 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 examine 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 gasoline has been used for barely greater than twenty years, beginning with the 2000-built Norwegian automotive ferry Glutra. What is going to additional underpin the expansion of LNG gasoline in delivery is the discount of methane slip – basically unburnt gasoline launched into the ambiance within the combustion course of. Methane is a strong greenhouse gasoline, with a world warming potential of 27-30 instances CO2 over a 100-year interval, in response to the EPA. Engine designers are already centered on clamping down on methane slip; higher combustion, higher environmental profile and higher gasoline consumption. Moreover, search for additional developments reminiscent of methane oxidation catalysts.
Electrifying alternatives
Advances in maritime battery know-how proceed, with battery producers and propulsion system integrators remaining busy all through 2022. There’s no cause to suppose 2023 will convey something however good tidings to all of them as elevated learnings and system improvement continues. The maritime battery market is predicted to develop to US$10Bn by 2030, and subsequent yr ought to see extra batteries put in in OSVs, ferries and tugs.
