Iwatani Opens Hydrogen Station for Commercial Demonstration in Toyota, Aichi Prefecture
—Developing Hydrogen Infrastructure Ahead of the Start of Widespread Adoption of Fuel Cell Vehicles in 2015—

 

Iwatani Corporation (Head office: Tokyo and Osaka; President: Masao Nomura; Paid-in capital: 20 billion yen), together with Toho Gas Co., Ltd., has constructed and commenced operation of a Hydrogen Station with 70MPa filling pressure in Toyota, Aichi Prefecture, as part of joint research (regional hydrogen supply infrastructure technology, social demonstrations, technical and social demonstration research) between the Research Association of Hydrogen Supply/Utilization Technology※1 (HySUT), of which Iwatani is a member, and the New Energy and Industrial Technology Development Organization (NEDO).

 

 

The Toyota Ecoful Town※2 Hydrogen Station was constructed by HySUT members Iwatani Corporation and Toyo Gas Co., Ltd. utilizing the combined achievements in technological development and operating knowledge amassed the companies have developed to date.
By adopting a package-type hydrogen station from German firm Linde incorporating one of the nation’s largest direct filling method※3 high-flow compressors, the station achieves improved convenience, takes up less space and reduces costs, and will conduct a comprehensive demonstration aimed at the future development of commercial hydrogen stations through the filling of fuel cell vehicles (“FCVs,” hereafter) and fuel cell buses (“FC buses,” hereafter).
At the station, Iwatani is responsible for the main package installation, which incorporates key equipment such as high-flow compressors and cooling units, as well as high-pressure gas equipment such as accumulators for storing high-pressure hydrogen gas, safety facilities, filling control and so on.

 

Meanwhile, Iwatani has built a consistent nationwide supply network covering everything from the manufacture to the supply and security of compressed hydrogen and liquefied hydrogen for industrial use, and with the latest addition following on from Tokyo, Osaka and Fukuoka, is now involved in the operation of hydrogen stations in each of Japan’s four major metropolitan areas.

 

As an advanced model aimed at the widespread adoption of FCVs in the environmental model city of Toyota, the Toyota Ecoful Town Hydrogen Station is contributing to the development of low-carbon society in environmental and car-oriented towns, and will play a big part towards the beginning of the widespread adoption of hydrogen stations and FCVs in 2015.

The City of Toyota collaborates with companies and citizens engaged in the development of cutting-edge environmental technologies and promotes initiatives aimed at the development of a vibrant low-carbon society. Toyota Ecoful Town, designated as a model area for low-carbon society, opened in May 18, 2012 as a facility for visualizing initiatives such as the latest environmental technologies, next-generation transportation technologies and smart energy experience. The hydrogen station opened as a new facility in Toyota Ecoful Town.

The direct filling method is a method which feeds compressed hydrogen gas directly from a hydrogen compressor into an FCV.

 

 

1. Outline

Ahead of the start of fuel cell vehicle (“FCV,” hereafter) sales to the general public from 2015, Iwatani Corporation and other energy companies made a joint declaration in January 2011 and announced the development of 100 stations nationwide, primarily around Japan’s four major metropolitan areas, beginning 2013. Ahead of this advance development, the hydrogen station will fulfill roles such as ascertaining expected cost reductions and evaluating the performance of the developed technologies as a model of a hydrogen station built to commercial specifications. Further, in conjunction with the low-carbon society initiatives implemented by the City of Toyota, the station will pursue activities to promote understanding of the technology, such as filling FC buses and other vehicles running throughout the city.

  

(1) Main Demonstration Items: 

  ①Smaller installation area, shortened construction schedule and
     lower costs through a package-type station  

  ②Evaluation of high-capacity and direct filling technologies for FCVs and FC buses  

  ③Activities to promote understanding ahead of widespread adoption  

 

(2) Installation Location: Motoshirocho 3-11, Toyota-shi, Aichi Prefecture (Inside Toyota Ecoful Town)

 

2. Equipment Flow and Main Specifications

Hydrogen is manufactured from city gas and FCVs and FC buses are filled with the hydrogen through filling units (high-flow compressors) and dispensers.
