Innovative Floating Ammonia Cracker Unit Receives Approval
According to a recent publication by Mitsui O.S.K. Lines (MOL), the company, in collaboration with HD Hyundai Heavy Industries and HD Korea Shipbuilding & Offshore Engineering, has secured Approval in Principle (AiP) from Lloyd’s Register for their groundbreaking Floating Ammonia Cracker Unit (FACU). This innovative technology is set to revolutionize the hydrogen supply chain by enabling direct conversion of ammonia into hydrogen offshore.
The FACU operates by thermally breaking down ammonia into hydrogen and nitrogen aboard specialized vessels. This method establishes a reliable and efficient supply chain for hydrogen without depending entirely on terrestrial infrastructure.
The development is anticipated to facilitate broader adoption of hydrogen energy solutions while aiding global efforts toward decarbonization. The design phase of the unit has been finalized, encompassing both process layout and overall configuration. Notably, Kellogg Brown & Root LLC contributed their expertise in ammonia cracking processes and module design to enhance project viability.
This advanced technology utilizes KBR’s H2ACT® process, which boasts an impressive capacity of producing 1,000 tons of hydrogen daily through a single train operation. Furthermore, U.S.-based Amogy Inc. has introduced an innovative catalyst solution that significantly boosts performance metrics.
The formal announcement took place on September 9 during the Gastech Exhibition & Conference 2025 held in Milan—one of the premier international events focused on energy innovation.
This floating ammonia cracker presents a viable alternative for regions where establishing large-scale onshore facilities poses challenges. By receiving ammonia at sea and converting it into usable hydrogen onboard before transporting it ashore, this system enhances efficiency in expanding access to clean energy sources.
