Operation from June 2009 is Scheduled Construction of a Liquid Hydrogen Plant Starts in Ichihara, Chiba Prefecture The First Plant in the Eastern Area Considers the Environment

Iwatani International Corporation

Iwatani International Corporation (Headquarters: Osaka & Tokyo, President: Akiji Makino, Capital: \20,000 million) will build a liquid hydrogen production plant in the premises of the Chiba Plant of the Iwatani Industrial Gases Corporation in Ichihara, Chiba Prefecture in order to reinforce a stable supply system to meet users’ needs; in response to the increased nationwide demand for hydrogen. With a predicted investment of around \3.7 billion, the plant is scheduled to commence in June 2009.
Liquid hydrogen is used in a wide range of industries, including space development, metallurgy, semiconductors, glass, and automobiles. Because of its advantageous features, such as the potential for mass supply, high purity and space saving, the needs of users for liquid hydrogen have been steadily increasing. Iwatani therefore decided to build a liquid hydrogen plant to cover the future increase in demand in the eastern areas of Japan.
The source of hydrogen will be supplied from adjacent factories. Using by-product hydrogen gas, a new production system, introduced in the plant, does not produce CO2.
It is the industry’s first such plant in the Kanto area, and our second production base following Hydro Edge (Sakai, Osaka) in the Kansai area Iwatani aims to stabilize the production and supply of liquid hydrogen in the eastern areas of Japan by extending our supply system with this liquid hydrogen plant.
The hydrogen market is expanding with the growth of next generation industries, such as semiconductors and photovoltaic cells. At the same time, many other industries have also used liquid hydrogen. We will meet these needs in a positive way. Towards the early realization of a future hydrogen-based society, we will promote the use of liquid hydrogen while ensuring security and improving the supply infrastructure.
