Tokyu Construction and Teijin complete successful trial

Tokyu Construction and Teijin complete successful trial of hydrogen fuel cell generators to supply power at Shibuya construction site.

Loughborough – 10th August 2023 – Tokyu Construction Co., Ltd. and partner of Intelligent Energy, Teijin Limited, have announced the completion of a trial whereby hydrogen fuel cell generators were used as power sources at a construction site around Tokyo’s Shibuya Station.

The successful trial, which ran from late June to mid-July 2023, evaluated reductions of noise and carbon dioxide emissions achieved by using hydrogen fuel cell generators instead of conventional gasoline generators. It revealed that the hydrogen fuel cell generators reduced noise from approximately 80 decibels to 60 decibels (*) compared to gasoline generators. It also cut CO2 emissions approximately 6kg (reference range) in ten hours, or more than 1,000 kg per year.

In addition to testing noise and emissions, Tokyu Construction and Teijin verified the workability and portability of the fuel cell and pressure vessel units. No special equipment was required to load and unload the fuel cell and pressure vessel units onto a vehicle for transport to the Shibuya construction office.

The hydrogen fuel cell generators are comprised of a fuel cell unit, featuring the IE-LIFT 1T fuel cell, and a companion pressure vessel unit, which supplies hydrogen fuel. The pressure vessel unit is a portable hydrogen fuel supply device equipped with three Ultressa® lightweight, corrosion resistant, composite pressure cylinders developed by Teijin Engineering Limited, a subsidiary of Teijin.

The generators have been used at the construction site to supply electricity for lighting and warning signs during night time construction work. They have helped to avoid the issues caused by existing gasoline power generators, which can disturb local residents with unwanted noise, odours and ground vibrations.

Teijin aims to begin marketing the fuel cell and pressure vessel units to various industries, including building and construction, in the spring of 2024.
