Spanish energy company Repsol and shipping giant A.P. Moller – Maersk (Maersk) completed the first bioethanol bunkering operation in the Port of Barcelona, according to the port authority on Wednesday (15 July). 

Repsol successfully supplied 2,800 metric tonnes (mt) of bioethanol to a Maersk container vessel, Antonia Maersk, in the first bunkering operation of its kind in the Port of Barcelona and one of the first in the Mediterranean. 

The operation demonstrates growing demand for alcohol-based marine fuels, as well as the readiness of the infrastructure, logistics, and operational capabilities required to support their deployment at commercial scale. 

Juan Abascal, Repsol’s Executive Managing Director of Industrial Transformation and Circular Economy, said: “With this supply, we reaffirm our commitment to the decarbonization of maritime transport through solutions that are available today and ready to scale in the future. 

“At Repsol, we provide shipping companies with a reliable supply chain and a multi-energy strategy that combines different renewable fuels to support the sector in a safe, competitive, and sustainable transition.”

The supply took place in the Port of Barcelona under fully commercial conditions, bringing together key players across the maritime value chain and demonstrating how collaboration can accelerate the adoption of lower-emission solutions in shipping. 

The delivery was carried out by Bahía Candela, Repsol’s newest bunker vessel, operated by Mureloil and designed to supply both conventional marine fuels and next-generation energy products. 

During the bunkering operation, Bahía Candela operated using its battery system, enabling the fuel transfer to be completed with zero local emissions, and further reducing the environmental footprint of the operation. 

Prior to the bunkering, Maersk tested ethanol on one of its smaller vessels, the 1,800 TEU feeder vessel Laura Maersk, which in 2023 became the world’s first dual-fuel container vessel able to operate on methanol. Today, Maersk has 23 dual-fuel container vessels designed to operate on methanol; however, the company continues to explore ethanol as an alternative fuel for its methanol-enabled vessels. Laura Maersk has performed sailings on 100% ethanol as well as blends of ethanol and methanol. 

Emma Mazhari, Vice President Energy Markets at Maersk, said: “Following the successful ethanol trials conducted on Laura Maersk, this latest bunkering of Antonia Maersk marks another important step in our efforts to explore scalable low-emission fuel solutions. 

“As the first ethanol trial on one of our large dual-fuel vessels, with a capacity of 16,000 TEU, it allows us to deepen our understanding of ethanol’s operational potential at scale. 

“Building on the experience we have gained with methanol, we are working closely with port authorities and industry partners to develop the infrastructure and procedures needed to support ethanol bunkering. Ethanol is one of several pathways we are pursuing to diversify our future fuel portfolio and help accelerate the development of new, viable liquid marine fuel markets.”

Global logistics group DP World recently said the company bunkered the first harbour tug to use 100% Hydrotreated Vegetable Oil (HVO) fuel at London Gateway, in collaboration with Svitzer.

Svitzer Thames handles some of the world’s largest container ships at the port, and switching from marine diesel to HVO can reduce CO₂ emissions by up to 700 metric tonnes (mt) annually, while also improving local air quality.

“DP World and Svitzer are working together to use biofuel on tugs to reduce emissions in the UK, enabling cargo owners to actively reduce supply chain emissions at the source,” DP World said in a social media post.  

“By transitioning to this lower lifecycle emissions solution, we are helping our customers to tackle scope 3 emissions and meet their sustainability goals along the supply chain.”

DP World partnered with marine services company Svitzer, under a partnership that will see its tug boats serving DP World’s ports transition to these fuels.

Manifold Times previously reported DP World supporting the bunkering of tugboat Svitzer Bargate using 100% Hydrotreated Vegetable Oil (HVO) in place of conventional diesel.

The operation was conducted at the Port of Southampton in the UK. 

The company added that the emissions savings from this activity form part of the last nautical mile carbon inset credits under its Carbon Inset Programme, enabling cargo owners to actively reduce supply chain emissions at the source.

Industry coalition SEA-LNG on Thursday (16 July) published its 2026 Mid-Year Market Review. 

It provides a snapshot of the current market conditions facing the methane pathway, with particular focus on the growth of liquefied biomethane (LBM/bio-LNG). This report comes as SEA-LNG celebrates its tenth anniversary and gains provisional consultative status at the International Maritime Organization (IMO).

According to analysis of vessel orders from January to June 2026 from SEA-LNG member DNV, LNG dual-fuel orders remain robust at 73 vessels, accounting for almost 90% of the alternatively fuelled order book, when compared with ammonia, hydrogen and methanol. Additionally, there are now 67 LNG bunker vessels in operation, plus 42 more on order.

The LNG order book continues to be dominated by vessels serving liner trades especially container vessels and pure car and truck carriers (PCTCs). This is consistent with recent analysis by the World Shipping Council which shows that LNG remains the preferred fuel for container ship owners, accounting for 58% of total tonnage ordered versus conventional fuels at 36%.

There was also an increase in bunkering volumes and infrastructure. According to analysis by Kpler, global LNG bunker volumes were around 770,000 cubic meters (m3) per month in the period January to May 2026. This represents an increase of about 13% on the same period in 2025 as more LNG fuelled vessels have entered into operation together with favourable LNG and conventional fuel prices.

Liquefied biomethane is bunkered routinely today, and liquefied e-methane is in development. Since the introduction of regulations like FuelEU Maritime, LBM supply and demand have grown significantly. Data from the European Biogas Association show biomethane production capacity reached 8.2 bcm a year by the end of Q2 2026. This represents an additional 1 bcm in a single year, or growth of 17%. The number of operational biogas plants rose from 1,678 to 1,975 plants with €36 billion of allocated capital investment driving the sector.

Steve Esau, SEA-LNG COO, said: “Despite geopolitical and regulatory uncertainties in 2026, the industry is maintaining momentum on the methane decarbonisation pathway. This year’s mid-year review confirms that methane is the practical and realistic solution for shipping decarbonisation. 

“This is reflected in the growing numbers of LNG-fuelled vessels, LNG bunker vessels, and LNG bunkering volumes, as well as biomethane bunkering and production growth. As we look ahead, with e-methane also materialising, we are confident in the trajectory of the methane pathway to decarbonisation.”

SEA-LNG is active at the IMO and EU to underline the importance of goal-based and technology-neutral decarbonisation regulations, and ensure a global market for low and net zero fuels. As the methane pathway continues to mature, efforts have shifted from raising awareness to sharing members’ collective expertise on important technical details that will, for example, further reduce global well-to-wake emissions and scale up bio- and e-methane development and deployment.

As part of these efforts, last week SEA-LNG was granted provisional consultative status at the IMO. This status will enable SEA-LNG to engage directly with Members States as it advocates for practical and realistic regulations to help move the maritime industry forward.

Peter Keller, SEA-LNG Chairman, said: “I have been with SEA-LNG since we founded it 10 years ago, and what strikes me is how methane has ramped up from a pathway to a clear runway for shipping decarbonisation. When building the first LNG-powered containership, I didn’t imagine that within ten years over 10% of the global fleet by deadweight could be powered by methane. 

“What started as a solution to reduce harmful local emissions has cemented itself as the practical and realistic option for reducing greenhouse gas emissions today and into the future. As I look ahead, the fundamentals are strong, the orderbook is growing, the bunkering infrastructure is expanding at a record pace, and biomethane and e-methane are building on LNG’s foundation. Just as we expected.”
