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.

Classification society DNV recently highlighted how complex methanol retrofits can be carried out in practice through a project involving COSCO Shipping, CHI Shanghai, MARIC, suppliers, and DNV. 

Its latest Maritime Impact article detailed challenges in design integration, construction, commissioning, and operations, while demonstrating how close collaboration and early planning support more efficient delivery and knowledge transfer: 

The world’s first methanol conversion project for a mega container carrier was completed at CHI‑Shanghai’s yard in September 2025. At nearly 400 metres in length and with a capacity of 20,000 TEU, the seven‑year‑old vessel became the first ship of its kind to be retrofitted to run on methanol. 

Delivered through close coordination between COSCO Shipping, CHI Shanghai, designers, suppliers, and DNV, and supported by a process of continuous learning, the project demonstrated that deep, first‑of‑a‑kind retrofits can be executed safely, on time, and at industrial scale.

Designing a methanol conversion for a megaship

The vessel’s fuel system, designed only for conventional fuels, required fundamental changes to enable safe and compliant methanol operation across propulsion, auxiliaries, storage, and safety systems.

The general design was developed by MARIC, while CHI Shanghai carried out the detailed engineering and served as EPC contractor. The scope included conversion of the ship’s MAN B&W 11S90 main engine and two of its four Wärtsilä auxiliary engines to dual‑fuel operation. In parallel, new methanol fuel tanks with a total capacity exceeding 15,000 cubic metres were installed forward of the engine room, together with new fuel preparation and supply systems.

Coordinating the complexity of retrofitting

Delivering this as a retrofit rather than a newbuild added complexity that is often underestimated. Existing structural arrangements could not simply be replaced, and new systems had to be integrated into confined spaces, requiring innovative construction sequences and tight interface management between suppliers. 

“This was a very complex project involving many parties, including engine makers, fuel system suppliers, and automation and safety specialists,” says Yan Hao, Commercial Director at CHI‑Shanghai. “It was also the first time all of these suppliers had worked together on a methanol retrofit of this scale. Coordination was critical.”

Swiss marine power company WinGD on Tuesday (19 May) said its first ethanol-fuelled X-DF-M/E engines have been ordered for two ore carriers to be built for Chinese owner Shandong Shipping Corporation and to operate under long-term charters for Brazil-headquartered global mining company Vale. 

The two Newcastlemax (325,000 DWT) vessels will be built by Beihai Shipbuilding in China, and will each be powered by a six-cylinder, 820mm-bore 6X82DF-M/E engine intended to run primarily on ethanol fuel.

The engines will be the first of the X-DF-M/E platform optimised for primarily ethanol use. The fuel supply and injection pressure will be modified from WinGD’s methanol-fuelled engine concept already in service to account for the difference in energy density between the two fuels, which otherwise share very similar properties and combustion characteristics. The contract includes options for further engine deliveries should the vessel series be extended.

WinGD Executive Director Sales Volkmar Galke, said: “These first ethanol-fuelled X-DF-M/E engines build on more than a decade of intensive investigation into alcohol fuels including ethanol and methanol. Securing orders for a top-tier charterer and ship operator is the best possible validation of those efforts. This is a clear signal that the shipboard technology and fuel infrastructure around ethanol as a marine fuel are ready, giving confidence to others considering ethanol as an option for maritime decarbonisation.”

Ethanol is gaining attention as a ship fuel due to its widespread and cost-competitive availability in several markets. These markets include Brazil, from where the vessels will deliver iron ore to China. According to Vale’s own investigations, the use of ethanol can reduce greenhouse gas emissions by around 90% compared with heavy fuel oil, depending on the fuel type and lifecycle assumptions.

Vale Director of Shipping Rodrigo Bermelho, said: “The adoption of ethanol as an alternative fuel is part of Vale’s strategy to combine flexibility and efficiency in the ships that transport our ore and places the company in a unique position for the energy transition in global shipping over the coming decades, whilst driving similar initiatives in the sector.  We are pleased to partner with Shandong and WinGD on the world’s first newbuilding order for ethanol-fueled ocean-going vessels.”

With the addition of ethanol-fuel capability for its X-DF-M/E platform, WinGD now offers unparalleled fuel flexibility across Diesel-cycle two-stroke engines. X-DF-M/E, alongside the ammonia-fuelled X-DF-A and high-pressure LNG-fuelled X-DF-HP platforms, are all based on the same robust engine architecture and injection concept – ensuring efficient conversion capability that does not lock owners into a single fuel option.

The engine deliveries are scheduled to take place in early 2029 depending on shipyard requirements.
