A consortium has actually protected European Union financing to establish remedies decreasing methane slip from aquatic engines, progressing the ecological and also environment advantages of dissolved gas (LNG) as a ship gas.

Coordinated by VTT Technical Research Centre of Finland, the Green Ray task combines numerous firms from throughout the delivery worth chain: shipyard Chantiers de l’Atlantique, ship proprietor CMA CGA, category culture DNV GL, innovation team Wärtsilä, the Finnish Meteorological Institute, ship supervisor MSC Cruises Management, charitable company Revolve Water and also power significant Shell.

Slated to run up until 2027 with around EUR7 million from Horizon Europe, the task will certainly establish on-engine innovations for low-pressure dual-fuel engines– both 2- and also four-stroke– along with an unique aftertreatment principle. These remedies will certainly be progressed to a high state of innovation preparedness, consisting of demonstrators mounted on 2 newbuilds and also one retrofitted to an existing vessel. All the innovations created in Green Ray will certainly likewise be totally qualified to make use of biography- or artificial methane as opposed to fossil LNG.

Wärtsilä will certainly establish innovation particularly for reduced stress four-stroke twin gas engines that makes it possible for methane slip decrease, raises performance and also reduced functional prices whatsoever engine tons. This innovation targets the biggest four-stroke engines on the marketplace as extensively utilized by cruise liner, ferryboats and also gas providers.

Wärtsilä will certainly likewise establish an on-engine innovation for two-stroke engines around a copyrighted LNG shot system to lower methane slip from vessels, container ships, and so on Both innovations will certainly be shown mixed-up in actual application throughout the task in partnership with the Green Ray companions.

The use LNG as an aquatic gas is increasing, driven by a strong supply framework, a clear change to cleaner gas and also substantial air contamination and also environment advantages. The problem of methane slip– unutilized and also hence unburned gas leaving right into the environment from engines and also throughout the manufacturing and also supply chain– is viewed as among the primary obstacles to larger uptake.

“Methane slip has become an important factor in ship owners’ decisions about whether to use LNG fuel,” claimed Kati Lehtoranta, Principal Scientist, VTT. “ With these promising technologies we aim to reduce the slip contributing directly to reduction of the total greenhouse gas emissions, opening this pathway to even wider segment of the maritime market.”

Shell has actually created an exclusive methane reduction driver system that has actually been laboratory checked and also scaled as much as an area presentation, where it was verified to be efficient not just in dramatically lowering methane slip (over 90%), however likewise in taking care of regular substances that can break down the driver, by means of the incorporation of a guard bed.

“Shell’s climate ambition to become a net-zero emissions energy business by 2050 will require us to explore a range of avenues that have the potential to help us, our partners, and customers to decarbonize the existing LNG value chain. We are continuously working to improve the value proposition of LNG through dedicated technology research, and we are keen to develop potential solutions to minimize methane slip at such a relevant project as Green Ray,” describes Alexander Boekhorst, VP Gas Processing and also Conversion Technology at Shell.

“This research will allow us to build on the continuous improvements made in reducing methane slip from engines over the past twenty years,” claimed Sebastiaan Bleuanus, General Manager, Research Coordination & & Funding, WärtsiläMarine Power “Taking these solutions for newbuilds and retrofits to near commercial readiness will be an important step for the long-term viability of LNG as a marine fuel.”
