Mitsui O.S.K. Lines, Ltd., HD Korea Shipbuilding & Offshore Engineering Co., Ltd. and HD Hyundai Heavy Industries Co., Ltd. announced that the Approval in Principle (AiP) was granted from Lloyd's Register for a floating ammonia cracker unit (FACU), jointly developed by the group for onshore H₂ supply. FACU is a solution that enables direct H₂ supply from offshore to onshore by equipping vessels with technology that thermally decomposes ammonia into H₂ and nitrogen. It is expected to accelerate the use of H₂ 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 tpd H₂ supply based on H2ACT^® technology, and Amogy Inc. (AMOGY) has provided a new catalyst solution.

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 H₂, 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 H₂ 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 H₂ supply chain toward decarbonization.
