Nikkiso receives order for a pump unit of hydrogen-fuelled ships

The pump unit will be designed and manufactured by combining the technologies of products for LNG-fuelled ships and hydrogen stations. This is scheduled for delivery in 2026.

The hydrogen-fuelled ship in which this pump unit will be installed equips a low speed two-stroke hydrogen-dual fuelled engine as the main propulsion engine. This is the first ship in the world to obtain an approval in principle (AiP) from Nippon Kaiji Kyokai (ClassNK) for a ship with the same type of engine as its main propulsion engine. This project, to develop the first hydrogen-fuelled ship, is part of the project ‘Development of marine hydrogen engines and marine hydrogen fuel tank and fuel supply system (MHFS)’ which was adopted by the Green Innovation (GI) Fund / Next-generation Ship Development of the New Energy and Industrial Technology Development Organization (NEDO).

Overview of the project

In response to the need to reduce greenhouse gas (GHG) emissions in the shipping sector, Kawasaki and two other companies proposed this project to NEDO's GI Fund, which was adopted in October 2021.

In this project, the three companies are simultaneously developing marine hydrogen-fuelled engines with different power ranges and applications, and Kawasaki is also responsible for the development of the MHFS. The ship with a low speed two-stroke hydrogen-fuelled engine is scheduled to begin demonstration operation in 2028.

About the pump unit

The pump unit on order from Kawasaki is a key component of the MHFS that supplies high-pressure hydrogen to a low speed two-stroke hydrogen-fuelled engine. This pump unit, which combines multiple types of pumps, is used to boost the pressure required by the engine in the process of supplying liquefied hydrogen from the hydrogen fuel tank to the evaporator.

The design and manufacturing are being carried out by the Clean Energy & Industrial Gases Group (CE&IG Group, California, US), part of Nikkiso's industrial division, and they will apply the technology of high-pressure fuel supply systems for LNG-fuelled ships for the pump units for the hydrogen-fuelled ships.

Nikkiso will contribute to achieving carbon neutrality in international shipping by providing pump units for hydrogen-fuelled ships.
