Liquid Wind is developing FlagshipONE

eMethanol producer Liquid Wind on Monday (11 April) said its lifecycle assessment concluded eMethanol produced from renewable energy sources can have carbon equivalence of up to 94% lower than fossil fuels.

The results are contained in a white paper* produced by Liquid Wind ahead of a webinar to be held on April 28. The white paper’s conclusion reinforces calls for maritime regulators to assess the carbon impact of marine fuels on a lifecycle basis, in the process providing the means to dramatically lower the carbon emissions from merchant shipping.

To meet the growing demand for carbon neutral fuel and the need to reduce CO2 emissions, Liquid Wind is developing FlagshipONE, a commercial-scale renewable eMethanol facility which will capture CO2 emissions from a biomass combined heat and power plant.

To quantify the environmental benefit, Liquid Wind performed an internal lifecycle analysis (LCA) to determine the emissions of the eMethanol to be produced at FlagshipONE, considering all stages of the eMethanol lifecycle and identifying the GHG reduction potential compared to conventional fuels.

The well-to-gate emissions of FlagshipONE eMethanol (life-cycle emission when leaving the production facility) are relatively small, at around -1.3 kg CO2eq per kg of eMethanol produced. About -1.4 kg of CO2 is from capturing the carbon and is credited as negative emissions.

When the scope is expanded to include the ‘use phase’, well-to-wake, the emissions of transport and combustion are considered. The captured CO2 is re-emitted, which results in a net positive climate change potential of about 5 gCO2eq/MJ.

Considering life cycle emissions, fossil-based fuels emit around 85-90 gCO2eq/MJ, which results in a reduction of about 94% when replaced with wind-based eMethanol. The well-to-wake emissions of eMethanol are compared to further marine fuel alternatives based on data provided in Brynolf, (2014) of Chalmers University, Sweden.

“Together with our consortium partners, Liquid Wind is demonstrating the potential that sustainable marine fuels can make to reducing carbon emissions when carbon is considered on a lifecycle basis,” said Claes Fredriksson, CEO and founder of Liquid Wind. 

“With further regulatory alignment, marine fuel buyers and end users can understand how to make their operations cleaner and greener and demonstrate that to their stakeholders.”

Liquid Wind has used Material Energy Flow Analysis (MEFA) to determine the carbon inventory of its production process. The MEFA has a modular approach, which handles the complexity of the system by carrying out an input-output analysis for each production step, which are investigated individually. All direct and indirect material or energy flows for each module are captured and include the scope 1 and 2 emissions.

AAL Shipping names methanol-ready multipurpose heavy lift vessel in China

Singapore-headquartered project heavy lift carrier AAL Shipping (AAL) on Thursday (13 March) said it held a formal naming ceremony for its fifth Super B-Class vessel, AAL Dubai

The 32,000 dwt AAL Dubai – a multipurpose heavy lift vessel that is methanol-ready – was officially named on March 12 at the CSSC Huangpu-Wenchong Shipyard in Guangzhou, China.

The AAL Dubai is engineered to transport a vast array of cargo, including heavy lift project equipment, breakbulk, and dry bulk, all on a single voyage. With a combined lifting capacity of 700 tonnes, this vessel is designed to offer high efficiency, cargo flexibility, and economies of scale to shippers worldwide.

The vessel will now embark on its maiden voyage, joining sister vessels AAL Limassol, AAL Hamburg, AAL Houston, and AAL Antwerp in serving project cargo customers across Asia, Europe, the Middle East, and the Americas.

“We are now over the halfway mark with our Super B-Class deliveries, and those already in service are exceeding our expectations,” said Liew Teck Liong, Chief Financial Officer at AAL.

“With these vessels, we have achieved both company and industry firsts, and we look forward to redefining what a heavy lift, multipurpose vessel can accomplish as we deploy them for complex cargo challenges.”

Later this year, AAL will take delivery of the AAL Dammam, which will be shortly followed by the AAL Newcastle and AAL Mumbai that have an increased maximum heavy lift capability of 800 tonnes.

Titan completes first LNG and bio-LNG bunkering op to MOL under new term contract

Titan Clean Fuels (Titan) on Monday (17 March) said it has completed the first LNG and liquefied biomethane (bio-LNG) bunkering operation of a new multi-delivery contract for Mitsui O.S.K. Lines’ vehicle carrier fleet.

On 16 March, Titan’s Alice Cosulich LNG bunkering vessel delivered 500 metric tonnes (mt) of bio-LNG and 400 mt of conventional LNG to the Celeste Ace vehicle carrier. The simultaneous operation (SIMOPS) bunkering took place in the Port of Zeebrugge’s International Car Operators (ICO) terminal.

Titan’s delivery of ISCC-EU-certified mass-balanced bio-LNG marks the first of a series of bio-LNG deliveries to the Japanese shipping company. The bio-LNG was produced using waste and residue, which reduces GHG emissions by up to 100% compared to marine diesel on a well-to-wake basis. LNG, bio-LNG, and renewable hydrogen-derived e-methane can be blended at any ratio and ‘dropped into’ existing LNG bunkering infrastructure with little to no modification.

Caspar Gooren, Commercial Director of Renewable Fuels at Titan, said: “This bunkering highlights the growing role of bio-LNG in decarbonizing international shipping today. With bio-LNG availability expanding, its deep decarbonization potential, and increasing commercial viability, the LNG pathway offers practical solutions for shipowners and operators. Moreover, with a global maritime leader like MOL putting its commercial weight behind bio-LNG, this is an exciting time for the clean fuels transition.”

Yoshikazu Urushitani, Marine Fuel GX Division General Manager at MOL, said: “We are exploring the use of ammonia and hydrogen fuels as part of our strategy to adopt clean alternative fuels, while moving to expand the use of LNG-fueled vessels and more quickly achieve a low-carbon society. We will also be early adopters of bio-LNG and synthetic LNG. Partnering with Titan, we will start using bio-LNG to lead the shipping industry in the transition to clean alternative fuels. We remain committed to adopting clean fuels to reach net zero GHG emissions by 2050.”

MOL currently operates five LNG-fuelled vehicle carriers and will have six more delivered by the middle of 2025.
