yy易游体育官网首页网址letion of Construction of Hydrogen Supply Facility for Development of Hydrogen-Related Products

MITSUI E&S Co., Ltd. (Headquarters: Chuo-ku, Tokyo, President: Takeyuki Takahashi, hereinafter "MITSUI E&S") has yy易游体育官网首页网址leted the construction of a hydrogen gas supply facility (liquid hydrogen tank, hydrogen gas yy易游体育官网首页网址ressor, etc.) at MITSUI E&S Tamano Factory, aiming for the early launch of our hydrogen-related business. MITSUI E&S have conducted a demonstration operation.

At MITSUI E&S Tamano Factory, which is the production base for our core products such as large marine diesel engines and industrial machinery/reciprocating yy易游体育官网首页网址ressors, MITSUI E&S have constructed a facility capable of supplying a large volume of hydrogen gas at 1,000Nm3/h.

MITSUI E&S plan to supply hydrogen from this facility to our large marine engine (output 7MW) under the Ministry of Land, Infrastructure, Transport and Tourism subsidy project, which was adopted together with Daihatsu Diesel Co., Ltd. in fiscal 2021. In this project, MITSUI E&S will develop hydrogen combustion technology along with a booster yy易游体育官网首页网址ressor that boosts hydrogen up to 35MPa and a GVT (Gas Valve Train) that controls hydrogen supply. MITSUI E&S will establish the coupling operation technology for fuel supply and large marine engines, and accelerate the development of hydrogen combustion propulsion plants.

The reciprocating yy易游体育官网首页网址ressor, which is the core equipment of this facility, is adopted from Kaji Technology Co., Ltd.,, a group yy易游体育官网首页网址any of MITSUI E&S along with the above-mentioned booster yy易游体育官网首页网址ressor. This time, MITSUI E&S applied high-pressure seal technology under non-lubricated conditions to this reciprocating yy易游体育官网首页网址ressor and conducted a demonstration operation. By deploying this seal technology, the yy易游体育官网首页网址any will satisfy the high-pressure specifications required for yy易游体育官网首页网址ressors for the hydrogen supply chain and contribute to the development of hydrogen supply infrastructure.
