Mitsui E&S Co., Ltd. has received an order from Tsuneishi Corporation for a VD4-250GH-OL high-pressure, high-flow H₂ compressor for use in Japan's offshore H₂ station, which is being built by JPN H2YDRO.

The goal of the Nippon Foundation Zero Emission Ships Project is to achieve carbon neutrality in the shipping sector amid the global trend toward decarbonization. As part of this project, the VD4-250GH-OL will be used at Japan's first offshore H₂ station to supply H₂ to H₂-fueled ships, including tugboats equipped with H₂ co-firing engines. The station is currently being built by JPN H2YDRO.

The VD4-250GH-OL's design is optimized for longevity. It enables stable H₂ compression with minimal downtime and is equipped with technologies based on long track record in high-flow compressors for petroleum refining and chemical plants all over the world by Mitsui E&S and extensive expertise in high-pressure H₂ compression technology by our group company, Kaji Technology, who have the largest share market at Japanese H₂ stations. The VD4-250GH-OL boasts high reliability and durability with the ability to compress H₂ up to 50 MPa at a flowrate of 100 kg/hr.

The compressor is also characterized by its high-pressure high flowrate. Even with this flowrate, it is physically smaller than existing compressors, making it a space-saving compressor that can be used in a wide range of processes for the transportation and supply of H₂.

Mitsui E&S began manufacturing reciprocating compressors in 1961 and has delivered more than 1,200 reciprocating compressors to customers all over the world, for use in essential oil refining and chemical plants. Mitsui E&S will continue to contribute to a recycling-oriented and decarbonized society through its supply of compressors to facilities such as H₂ stations and H₂ production equipment in the H₂ market, as well as to SAF plants.
