Crowley christens US first fully electric tugboat “eWolf” at Port of San Diego

US-owned maritime, energy and logistics solutions company Crowley on Wednesday (26 June) said it christened the eWolf, America’s first all-electric ship assist harbor tugboat. 

Built by Master Boat Builders in Coden, Ala., the 82-foot vessel delivers 70 tonnes of bollard pull – stronger than its conventional predecessor. 

The eTug also features a fully integrated electrical package for battery energy storage by ABB with advanced technology for mariner safety. The eTug will enter commercial service this week.

“The eWolf is a historic milestone in the maritime industry and Crowley’s legacy, and underscores our company’s commitment to serve as global sustainability leaders and innovators,” said Tom Crowley, Chairman and CEO.  

“The all-electric tugboat is the most technologically advanced vessel of its kind, and eWolf will help our customers and communities reach their decarbonisation goals while delivering capabilities that strengthen our vital supply chain.”

“We congratulate the people whose tireless dedication brought the eWolf to fruition with our partners at the federal, state and local government, setting a new standard not just in America, but globally.”

“Crowley’s first-of-its-kind electric tugboat is a game changer. It checks all the boxes by providing environmental, economic, and operational benefits for our communities and maritime industry,” said Frank Urtasun, Port of San Diego Chairman. 

“This is truly a story of teamwork and collaboration. We are proud to work with Crowley and our state and local partners on this and other electrification initiatives at and around our port, including electric cargo handling equipment like our all-electric mobile harbor cranes, our microgrid, vessel shore power, and more.”

eWolf is supported by a new microgrid shoreside charging station that enables the tug to operate at full performance daily on electricity.

Crowley was joined at the vessel christening by project partners including the Port of San Diego, San Diego County Air Pollution Control District, the California Air Resources Board (CARB), the U.S. EPA and the U.S. Maritime Administration. The collaborative effort among federal, state and local partners to decarbonise the port furthers the shared goal of improving air quality for San Diego.

“SDAPCD is proud to have provided funding for the eWolf project, a groundbreaking initiative aimed at transitioning from traditional diesel-powered vessels to electric propulsion systems,” said Shu, City of La Mesa Councilmember and SDAPCD Governing Board Chair. 

“The eWolf exemplifies how collaboration between government and private partners can drive meaningful change, contributing significantly to a cleaner, healthier environment for everyone.”

The company chose eWolf’s name in a nod to a tugboat in the company’s initial fleet, the Sea Wolf, which operated more than a century ago in California.

MOL inks bio-LNG bunker fuel supply deals with Titan and Axpo for car carriers in Europe

Mitsui OSK Lines (MOL) on Thursday (18 July) said it has signed new supply agreements in Northern Europe and the Mediterranean region to expand the use of bio-LNG marine fuel on MOL-operated LNG-fuelled car carriers.

Titan, part of Amsterdam-based Molgas, will continue to supply bio-LNG fuel in Northwest Europe, while Axpo will take charge of supply in the Mediterranean region.

MOL said the agreement makes it possible for its company to supply bio-LNG fuel for automobile carriers in the Mediterranean region, specifically Port of Malaga and Barcelona in Spain, following the bio-LNG fuel supply agreement in Western Europe, which commenced in March last year.

The bio-LNG fuel to be supplied in this initiative has a lifecycle carbon intensity (carbon dioxide emissions per unit of energy consumption) of -15 g-CO2/MJ or less, from production through consumption. Furthermore, this bio-LNG fuel has obtained International Sustainability and Carbon Certification (ISCC-EU). 

“Through this supply agreement, MOL has established a framework that ensures a continuous and stable supply of bio-LNG fuel not only in Northern Europe but also in the Mediterranean,” the company said.

As part of the group’s efforts to adopt alternative fuels and achieve net-zero greenhouse gas (GHG) emissions, it is utilising LNG-fuelled vessels as a bridge solution to facilitate the transition to carbon-neutral fuels such as bio-LNG and synthetic LNG (e-methane).

In 2025, MOL signed a bio LNG fuel supply agreement in Northwest Europe with Titan, part of the Molgas, and MOL has continued this bio LNG fuel supply agreement with the same company in 2026 as well.

Kvasir Technologies lands EUR 10 million to scale bio bunker fuel production

Danish biofuel startup Kvasir Technologies on Thursday (18 June) said it has raised EUR 10 million (USD 11.4 million) in a Series A investment round with participation from European Energy as a new investor, alongside existing investors EIFO, Maersk Growth and Footprint Fund. 

The Series A round provides capital to develop and design a new commercial production plant and scale climate-neutral drop-in fuel to be used in existing vessels.

At the same time, European Energy and Kvasir Technologies are entering into a strategic partnership by establishing the company KVEEN Biofuels, which is working towards the construction of a commercial-scale plant to produce biofuels using Kvasir Technologies’ patented technology.

“This investment round enables us to take the next crucial steps in developing and scaling our technology. At the same time, it underlines that there is still strong support for solutions that can deliver real climate impact in the maritime sector,” said Joachim Bachmann Nielsen, Ph.D. in Chemical Engineering and CEO of Kvasir Technologies.

Kvasir Technologies, a spin-out from research at the Technical University of Denmark (DTU), has developed a new technology to convert a wide range of non-edible lignin- based residues from agriculture and forestry into refined biofuels for shipping.

The climate-neutral biofuel can serve as an immediate replacement for fossil marine fuel without the need to modify ship engines or change existing infrastructure.

The new funding will be used, among other things, to scale the technology at Kvasir Technologies’ test facility in Fredericia, which can produce up to 2 metric tonnes (mt) of biofuel per day.

At the same time, development work will begin on the first commercial plant in the city of Aabenraa in the southern part of Jutland, which will demonstrate the technology on an industrial scale.

BeHydro secures LR’s first class approval for 100% hydrogen marine engine

Classification society Lloyd’s Register (LR) on Wednesday (17 June) said it has issued the first Type Approval Certificate for a 100% hydrogen-fuelled, spark-ignited marine engine.

The approval has been awarded to the hydrogen engine developed by BeHydro and confirms the design meets LR’s requirements for safety, performance and reliability in marine applications.

The engine has been developed and tested at ABC Engines’ facility in Ghent and is designed to operate entirely on hydrogen, without the need for pilot fuels. This simplifies system design and removes onboard carbon emissions at source, positioning the technology as a practical option for operators exploring zero-carbon propulsion.

Claudene Sharp-Patel, Global Technical Director, Lloyd’s Register, said: “The issue of this Type Approval Certificate demonstrates that hydrogen-fuelled internal combustion engine technology is continuing to mature as a viable option for maritime applications.

“For shipowners and operators, independent certification is essential in building confidence that emerging fuel technologies can meet the industry’s expectations for safety, reliability and operational performance.”

Tim Berckmoes, CEO at ABC Engines, said: “This LRS type approval of our BeHydro 100% hydrogen engines with zero emissions is a confirmation of the future proof technology that BeHydro can offer to innovative shipowners worldwide.

“The 100% hydrogen engine range is available from 900 kW till 2670 kW for different marine applications.”

LR previously awarded Type Approval to BeHydro for its hydrogen-powered dual-fuel engine in 2023, which was the first Type Approval for a dual-fuel hydrogen engine.
