Taking advantage of the long-fostered ultra-high pressure gas technology, Toyoko Kagaku has developed a small-scaled hydrogen (H2) station unit of packaged type which has a disaster preventing function and is responsive to the H2 Fueling Protocol for 70MPa FCVs.

The unit has packaged the on-site H2 production system using electrolysis and also associated the fuel cell system, so that H2 can be supplied to FCVs at an ordinary time and anti-disaster measures may be taken to supply electricity and hot water by H2 power generation in case of emergency. The power generation at the time of emergency is designed to last for 1 to 2 weeks for several ordinary households.

The system consists of water electrolytic H2 generation system, booster (pressurizing up to 82MPa), accumulator and dispenser. It enables to fill one to two FCVs per week at a filling pressure of 70MPa.

The unit was adopted as the “H2 Station Co-development Verification Facility” which is a private sector-oriented project not depending upon any subsidization arisen by Choshu Industry and Riken Keiki as well as Toyoko Kagaku. They built up and opened on March 27 their “Solar Hydrogen Power Station (SHiPS) of H2 station originally developed to verify a renewable energy in the premises adjacent to Choshu Industry’s head office in Yamaguchi Prefecture.

The company is planning to make the unit compact-sized furthermore, so that FCV filling units or fuel cell forklift (FCFL) filling units of 35MPa can be designed and produced to meet needs, and to develop the business taking advantage of its nationwide network.
