Mitsubishi Shipbuilding Co., Ltd., a part of Mitsubishi Heavy Industries (MHI) Group, on Friday (26 June) said it has received an order from Hitachi Zosen Marine Engine (HZME) for its MAmmoSS® ammonia fuel handling system.

HZME is a dual licensee of Everllence SE and WinGD, major licensors of marine engines. MAmmoSS® will be designed and optimized to be compatible with the ammonia marine engines of these two licensors, and after delivery to HZME’s facility, will be used for shop tests of both engines.

The company said decarbonisation in global shipping is a critical issue, and ammonia, which does not emit CO2 when burned, is attracting attention as a next-generation marine fuel that will significantly contribute to reducing GHG emissions in the shipping industry. 

“However, as ammonia is a toxic fluid, safe handling technology onboard ships is essential and is expected to drive demand for MAmmoSS®,” it said. 

Going forward, Mitsubishi Shipbuilding said it will continue to provide safe and reliable products for ammonia-fuelled vessels to support the expected market expansion.

Everllence recently announced the successful Type Approval Test (TAT) of its ME-LGIA ammonia-burning engine at its Research Centre Copenhagen (RCC). 

Eight classification societies oversaw the testing that took place from 10 to 12 June, marking the latest phase in the engine’s journey towards its market debut.  

Bjarne Foldager, Head of Two-Stroke Business, Everllence, said: “The TAT is yet another important step as we definitively move from concept development to seagoing engine operation. It confirms the Everllence B&W ME-LGIA as ready for on-board installation and is the last test before actual sea and gas trials. 

“This engine sets new benchmarks in zero-carbon propulsion and digitally connected performance, and has attracted great interest since its development was announced in 2019. It stands testament to Everllence’s unique ability to meet demands and bring innovative fuels to market.”

Everllence officially marketed the ME-LGIA engines at a two-day event in Copenhagen in November 2025. Using the Diesel principle and the well-known, dual-fuel Liquid Gas Injection concept, the engine has a proven track record of several hundred thousand operational hours.

Ole Pyndt Hansen, Senior Vice President, Head of Two-Stroke R&D, Everllence, said: “The TAT is also important in relation to maturing IMO ammonia regulations as it is vital that rules and guidelines are in line with reality to optimise safety onboard vessels. 

“This experience comes from industry and the first ammonia-driven ships, which are expected to operate at sea during 2026, will act as compelling input for the development of these guidelines.”

Everllence also noted that the ammonia TAT marked the end of an era with it being the final TAT at the RCC in Copenhagen before the company moves location to outside the city in late-2027.

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.
