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.”

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.”

International shipping association BIMCO on Monday (13 July) highlighted its Biofuel Clause for Time Charter Parties 2026 and outlined the clause’s key provisions and what they mean for shipowners and charterers:

As the shipping industry continues its search for viable pathways towards decarbonisation, biofuels have emerged as one of the more immediately available transitional options. They can, in many cases, be used with little or no modification to existing engines and fuel systems, and they offer a practical means of addressing regulatory frameworks.

Recognising this, BIMCO has developed the Biofuel Clause for Time Charter Parties 2026, giving owners and charterers a dedicated contractual framework for the supply and consumption of biofuel during a time charter. 

The clause was developed through BIMCO’s established drafting process, bringing together representatives from owners, charterers, a fuel expert and a P&I Club representative, supported by broad industry consultation. The result is a clause that sets out, in detail, how responsibilities and costs relating to biofuel should be allocated between the parties. 

Why a dedicated clause is needed 

Time charter parties are typically built around the use of conventional fuels, and their speed, consumption and quality provisions are drafted with that assumption in mind. Biofuels differ from conventional fuels in several respects that matter contractually. They can vary considerably in specification and blend, they generally have a lower energy content, and their storage stability over time is generally more limited. Without specific wording addressing these characteristics, a charter party may leave important questions unanswered, including which biofuel specifications are acceptable, how fuel quality is to be verified, how speed and consumption warranties should be adjusted, and what happens if biofuel is not used within a reasonable time. 

The Biofuel Clause for Time Charter Parties 2026 addresses each of these points directly, giving both parties a clear and predictable basis for incorporating biofuel into their operations. 

What the clause covers 

At its core, the clause allows charterers to supply biofuel that meets specifications set out in the clause itself, based on the ISO 8217 fuel standard together with recognised biofuel component standards such as EN 14214, ASTM D6751 and EN 15940. Where charterers wish to supply a biofuel outside these agreed specifications, they may do so only with the owners’ prior written consent, and owners retain the right to require independent quality testing before giving that consent. 

The clause also sets out obligations around notice, fuel quality and segregation. Charterers must give owners reasonable advance notice of an intended biofuel supply, including its specification, blend and quantity, together with written instructions on the intended timing of consumption. Owners, for their part, warrant that the vessel and crew are properly equipped and trained to handle the biofuel safely, and that any tank cleaning required to accommodate the biofuel is carried out at the charterers’ expense where reasonably necessary. The clause further ensures that standard charter party provisions on sampling and quality testing apply equally to biofuel, avoiding the need for a separate regime 

Perhaps the most technically significant element of the clause is subclause (j), which addresses the adjustment of speed and consumption warranties. Because biofuels generally have a different lower calorific value than the conventional fuels on which such warranties are normally based, the clause provides two mechanisms for adjustment: either an agreed percentage adjustment, or a calculation based on the relative calorific values of the reference fuel and the biofuel supplied. Where the parties do not specify a percentage, the calorific value method applies by default. 

The clause further deals with the practicalities of biofuel’s shorter storage life, requiring that any biofuel supplied be consumed within an agreed period, defaulting to ninety days, with a further testing and consumption process if that period is exceeded. Provision is also made for any biofuel remaining on board at redelivery. 

Key points for the parties to consider 

While the clause is designed to be workable as a standard text, several matters call for particular attention before it is incorporated into a charter party. 

The maximum blend ratio inserted in subclause (a) deserves careful thought on both sides. Owners will want assurance that the vessel and its engines can safely accommodate the proposed blend, while charterers will want a ratio that gives them commercial flexibility. The clause includes a prominent reminder to this effect, and parties should not treat the blend percentage as a routine detail to be filled in without discussion. 

Closely related is the effect of biofuel consumption on speed and performance warranties. Because biofuels can behave differently from conventional fuels in terms of energy content, parties should consider in advance which adjustment mechanism under subclause (j) is most appropriate for their charter, and should be satisfied that they understand how any calculation will operate in practice. Owners in particular should be prepared to provide supporting documentation promptly if a speed adjustment becomes necessary. 

Parties should also give thought to the vessel’s technical readiness. The owners’ warranty regarding equipment and crew competence is an important safeguard, but it depends on the necessary preparations genuinely having been completed before biofuel is supplied. Equally, the allocation of tank cleaning costs under the clause rewards early planning, since unresolved questions about tank condition can lead to disputes over cost allocation later. 

Finally, the storage and consumption timeframes in subclause (k) merit attention given the more limited shelf life of many biofuels compared with conventional fuels. Parties operating on trades with longer voyage patterns, or with less predictable bunkering opportunities, may wish to consider whether the default periods are suitable or whether alternative timeframes should be agreed. 

A collaborative response to an evolving market 

The Biofuel Clause for Time Charter Parties 2026 is the result of a collaborative and consensual process, and BIMCO is grateful to the drafting team for their considerable time, effort and commitment in producing the clause. The team comprised Lars Mathiasen of Torm, Jenny Bazakas of Norden, Michael Rasmussen of Hafnia, Mathias Drost of CMA CGM, Kelly Vouvoussiras of Rio Tinto, Gunnar Kjeldsen of Bunker Holding Group, and Joanne Sharma of Steamship Mutual P&I. 

The clause reflects BIMCO’s broader approach to contractual development, identifying an emerging operational need, bringing together the relevant commercial and technical expertise, and producing a clause that has been tested against a wide range of industry views before publication. As biofuel use continues to grow across the fleet, the clause offers owners and charterers a considered and balanced starting point for managing its use under a time charter party.
