Lloyd’s Register grants AiP for floating ammonia cracker unit for onshore hydrogen supply

Mitsui O.S.K. Lines (MOL), HD Korea Shipbuilding & Offshore Engineering (HD KSOE) and HD Hyundai Heavy Industries (HHI) have received Approval in Principle (AiP) from Lloyd’s Register for a floating ammonia cracker unit (FACU) jointly developed for onshore hydrogen supply.

The FACU concept enables direct hydrogen supply from offshore to onshore by equipping vessels with technology that thermally decomposes ammonia into hydrogen and nitrogen. MOL, HD KSOE and HHI have completed the conceptual design, including the process layout and general arrangement.

Kellogg Brown & Root (KBR) collaborated on the ammonia cracking process and module design, enabling a single-train capacity of 1,000 tonnes per day of hydrogen supply based on its H2ACT® technology. Amogy provided a high-performance catalyst solution designed for efficient ammonia decomposition with advantages in offshore applications.

By receiving ammonia, cracking it onboard, and delivering hydrogen to shore, the solution aims to contribute to stable clean energy supply in regions where building onshore facilities is difficult and support the development of a hydrogen supply chain for decarbonisation.
