Korean companies Vinssen and Samsung Heavy Industries (Samsung) will collaborate with US-based Amogy in a new joint development project (JDP) aimed at keeping up with maritime environmental regulations.

The trio intends to provide onboard power by producing hydrogen through Amogy’s ammonia cracking technology, which can be used in Vinssen’s PEM fuel cells.

It aims to integrate the design with existing large commercial vessels, but has not yet specified a timeline or capacity details of the project.

This comes as the International Maritime Organization (IMO) imposes decarbonisation targets on the marine sector.

IMO strategy sets a goal to reduce international shipping emissions by 20% by 2030, 70% by 2040 and Net Zero around 2050, while also achieving at least 5% uptake of zero or near-zero emission fuels by 2030.

In a statement, Vinssen said the success of the JDP would “significantly accelerate” 100% carbon-free propulsion ships.

Amogy’s technology has been backed by maritime majors, with tens of millions in venture funding raised.

Vinssen and Samsung both contributed to an ammonia-fuelled LR2 tanker, which deployed an onboard ammonia cracking system, in September 2025.
