‘World’s first’ ship-to-ship ammonia bunkering

Ammonia fuel was transferred directly by connecting a bunkering vessel and a receiving vessel via transfer hoses.

At a Japanese quay, ammonia fuel was transferred from an ammonia carrier to an ammonia-fuelled medium gas carrier (AFMGC).

Ammonia’s toxicity makes it difficult to handle, so the bunkering operation is an ‘example of the fuel-supply framework that will be required for the widespread adoption of ammonia-fuelled vessels’, claims the Japanese shipping company NYK Line.

The AFMGC is currently in the final stage of construction and is scheduled to be completed in November 2026.

The AFMGC is a Green Innovation Fund Project by Japan’s New Energy and Industrial Technology Development Organization (NEDO).

The ¥2tln-NEDO fund was created to accelerate carbon neutrality in Japan’s energy and industrial sector by 2050. The fund provides R&D and support with implementing projects for up to a decade.

The project was a joint venture by NYK Line, and Japan Marine United Corporation, Nihon Shipyard Co., Ltd., Mitsubishi Gas Chemical Company, Inc., and Kokuka Sangyo Co., Ltd.
