AiP Granted from Lloyd's Register for Floating Ammonia Cracker Unit for Onshore Hydrogen Supply Solution

September 10, 2025

Mitsui O.S.K. Lines, Ltd. (MOL; President & CEO: Takeshi Hashimoto), HD Korea Shipbuilding & Offshore Engineering Co., Ltd. (HD KSOE), and HD Hyundai Heavy Industries Co., Ltd. (HHI) today announced that the Approval in Principle (AiP) was granted from Lloyd's Register for Floating Ammonia Cracker Unit (FACU), jointly developed by the group for onshore hydrogen supply. FACU is a solution that enables direct hydrogen supply from offshore to onshore by equipping vessels with technology that thermally decomposes ammonia into hydrogen and nitrogen. It is expected to accelerate the use of hydrogen energy toward the realization of a decarbonized society.

MOL, HD KSOE and HHI have finalized the conceptual design, including the process layout and general arrangement of FACU. In support of this achievement, Kellogg Brown & Root LLC (KBR) collaborated on the ammonia cracking process and module design, enabling a single-train capacity of 1,000 ton/day hydrogen supply based on H2ACT® technology, and Amogy Inc. (AMOGY) has provided a new catalyst solution (Note).

The presentation ceremony was held on September 9 at the Gastech Exhibition & Conference 2025, one of the world's largest international energy exhibitions and conferences, in Milan, Italy. As the demand for hydrogen, a clean energy source, continues to grow, establishing a robust supply chain is crucial for its widespread deployment. By receiving ammonia, cracking it onboard, and delivering hydrogen to onshore, this solution contributes to the stable supply of clean energy in areas where building onshore facilities is challenging, and the establishment of a hydrogen supply chain toward decarbonization.
