A consortium including technology group Wärtsilä has secured European Union funding to develop solutions minimising methane slip from marine engines, advancing the environmental and climate benefits of LNG as a bunker fuel.

Coordinated by VTT Technical Research Centre of Finland, the Green Ray project brings together several companies from across the shipping value chain: shipyard Chantiers de l’Atlantique, ship owner CMA CGA, classification society DNV GL, the Finnish Meteorological Institute, ship manager MSC Cruises Management, non-profit organisation Revolve Water and energy major Shell.

The project will develop on-engine technologies for low-pressure dual-fuel engines – both 2- and 4-stroke – as well as a novel aftertreatment concept. These solutions will be advanced to a high state of technology readiness, including demonstrators installed on two newbuilds and one retrofitted to an existing vessel. All the technologies developed in Green Ray will also be fully capable to utilize bio- or synthetic methane instead of fossil LNG.

Wärtsilä will develop technology specifically for low pressure 4-stroke dual fuel engines that enables methane slip reduction, increases efficiency and lower operational costs at all engine loads. This technology targets the largest four-stroke engines on the market as widely used by cruise ships, ferries and gas carriers.

Wärtsilä will also develop an on-engine technology for 2-stroke engines around a patented LNG injection system to reduce methane slip from tankers, container ships, etc. Both technologies will be demonstrated at sea in real application during the project in collaboration with the Green Ray partners.

The use of LNG as a marine fuel is accelerating, driven by a well-developed supply infrastructure, a clear transition to cleaner fuels and significant air pollution and climate benefits. The issue of methane slip – unutilized and thus unburned fuel escaping into the atmosphere from engines and across the production and supply chain – is seen as one of the main challenges to wider uptake.

“Methane slip has become an important factor in ship owners’ decisions about whether to use LNG fuel,” said 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 developed a proprietary methane abatement catalyst system that has been lab tested and scaled up to a field demonstration, where it was proven to be effective not only in significantly reducing methane slip (over 90%), but also in handling typical compounds that can degrade the catalyst, via the inclusion 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 decarbonise 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 minimise methane slip at such a relevant project as Green Ray,” explains Alexander Boekhorst, VP Gas Processing and 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,” said Sebastiaan Bleuanus, General Manager, Research Coordination & Funding, Wärtsilä Marine 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.”

The project has received funding of around €7 million from Horizon Europe. It will run until 2027.

Kambara Kisen orders methanol dual-fuel bulker from Tsuneishi Shipbuilding

Japanese shipowner Kambara Kisen has ordered a 65,700-dwt methanol dual-fuel dry bulk carrier newbuilding from Tsuneishi Shipbuilding Co., Ltd, according to Mitsui O.S.K. Lines (MOL) on Wednesday (20 September).

MOL said it signed a basic agreement on time charter for the newbuilding that is slated to be delivered in 2027. 

The vessel will be designed to use e-methanol produced primarily by synthesising recovered CO2 and hydrogen produced using renewable energy sources, and bio-methanol derived from biogas. 

The vessel's design maximises cargo space while ensuring sufficient methanol tank capacity set to allow the required navigational distance assuming various routes, at the same time maximising cargo space. 

MOL added the vessel is expected to serve mainly in the transport of biomass fuels from the east coast of North America to Europe and the U.K. and within the Pacific region, as well as grain from the east coast of South America and the U.S. Gulf Coast to Europe and the Far East.

Details on the time-charter contract:

Shipowner: Kambara Kisen wholly owned subsidiary
Charterer: MOL Drybulk Ltd.
Charter period 2027: -

Details on the newbuilding methanol dual fuel bulk carrier:

LOA: About 200 m
Breadth: About 32.25 m
Draft: About 13.80 m
Deadweight: About 65,700 MT
Hold capacity: About 81,500m3
Shipyard: Tsuneishi Shipbuilding Co., Ltd.

Argus Media: Alternatives may drive methanol market growth

Driven by low-carbon policies and regulations, the transportation sector — especially the marine fuels industry — could be a source of heightened demand, according to Argus.

RESIZED Argus media

The growth of sustainable alternatives to traditional methanol production sources likely will shape the market over the next several years, industry leaders said this week at the Argus Methanol Forum.

20 September 

Driven by low-carbon policies and regulations, the transportation sector — especially the marine fuels industry — could be a source of heightened demand.

"The aim is to be net zero by 2050 but [those solutions are] expensive today and one of the main challenges to build e-methanol or bio-methanol plants is a huge queue for these pieces of equipment that aren't available," Anita Gajadhar, executive director for Swiss-based methanol producer Proman, said.

Bio-based and e-methanol plants of commercial scale, like Proman's natural gas-fed 1.9 million metric tonne/yr M5000 plant in Trinidad and Tobago, are not ready today.

"But that's not to say 10 years from now they won't be there," Gajadhar added.

Smaller projects are popping up. Dutch fuels and gas supplier OCI Global announced plans last week to double the green methanol capacity at its Beaumont, Texas, facility to 400,000 t/yr and will add e-methanol to production for the first time. Production will use feedstocks such as renewable natural gas (RNG), green hydrogen and biogas.

The globally oversupplied methanol market will not get any major supply additions starting in 2024 until 2027. But that oversupply will not last long, Gajadhar said.

Global demand has slowed this year, driven by stagnate economic growth and higher interest rates, according to industry observers.

As much as half of methanol demand is tied to GDP growth, with total methanol demand estimates at 88.9mn t globally in 2023. This is essentially flat from 2022, but up from 88.3m t in 2021 and 87.7mn t in 2020, Dave McCaskill, vice-president of methanol and derivatives for Argus Media's consulting service, said.

Demand is not expected to rebound to 2019 levels of 89.6mn t until 2024 or 2025, he added.

The period of oversupply combined with lackluster demand places methanol in a transition period, Gajadhar said, which opens the door for sustainable feedstock alternatives to shape market growth.

Danish container shipping giant Maersk and French marine logistics company CMA-CGM announced earlier this week a partnership to drive decarbonization in shipping. The partnership seeks to develop fuel and operations standards for bunkering with alternative fuels. The companies will develop net-zero solutions, including new technology and alternative fuels.

Maersk has previously ordered dual-fuel methanol-powered vessels and CMA-CGM LNG-propelled vessels.

The demand for alternative feedstock-derived fuels is there, but the ability to scale-up such production lags. Certified lower-carbon methanol produced using carbon capture and sequestration — also known as blue methanol— can ramp up much more quickly, according to Gajadhar.

Royal Caribbean completes over 12 weeks of bio bunker fuel testing in Europe

Royal Caribbean Group on Tuesday (19 September) said it successfully completed over 12 consecutive weeks of biofuel testing in Europe. 

Royal Caribbean International’s Symphony of the Seas became the first ship in the maritime industry to successfully test and use a biofuel blend in Barcelona to meet part of her fuel needs. 

The company confirmed onboard technical systems met operational standards, without quality or safety concerns, demonstrating the biofuel blend is a reliable “drop in” supply of lower emission energy that ships can use to set sail across Europe and beyond. 

The tests across Europe also provided valuable data to understand the availability and scalability of biofuel in the region, the firm added. 

Jason Liberty, president and CEO, Royal Caribbean Group, said: “This is a pivotal moment for Royal Caribbean Group’s alternative fuel journey.”

“Following our successful trial of biofuels this summer, we are one step closer to bringing our vision for net-zero cruising to life. As we strive to protect and promote the vibrant oceans we sail, we are determined to accelerate innovation and improve how we deliver vacation experiences responsibly.”

President of the Port of Barcelona, Lluís Salvadó, said: “Royal Caribbean’s success is a clear example of how commitment to innovation makes possible the development of solutions to decarbonise the maritime sector.”

“In this case, it involves the cruise sector and focuses on biofuels, an area in which the Port of Barcelona is already working to become an energy hub, producing and supplying zero carbon fuels, such as green hydrogen and ammonia, and of other almost zero-carbon alternative fuels, such as methanol, biofuels or synthetic fuels. Innovation and collaboration between ports and shipping companies is key to accelerate the decarbonisation of maritime transport.”

The company began testing biofuels last year and expanded the trail this summer in Europe to two additional ships — Royal Caribbean International’s Symphony of the Seas and Celebrity Cruises’ Celebrity Apex

The sustainable biofuel blends tested were produced by purifying renewable raw materials like waste oils and fats and combining them with fuel oil to create an alternative fuel that is cleaner and more sustainable. The biofuel blends tested are accredited by International Sustainability and Carbon Certification (ISCC), a globally recognized organization that ensures sustainability of biofuels and verifies reductions of related emissions.

With Symphony of the Seas departing from the Port of Barcelona and Celebrity Apex departing from the Port of Rotterdam, both ships accomplished multiple sailings using biofuel and contributed critical data on the fuel’s capabilities. 

“These results will help accelerate Royal Caribbean Group’s plans to continue testing the use of different types of biofuels on upcoming European sailings this fall. The company is exploring strategic partnerships with suppliers and ports to ensure the availability of biofuel and infrastructures to advance the maritime energy transition,” the firm said.
