KAWASAKI, JAPAN—Toshiba Energy Systems & Solutions Corporation (hereinafter, “Toshiba ESS”) today announced that it has delivered the H2Rex^TM pure hydrogen fuel cell system (rated output 100 kW) to the head office of U Group Company in Nagano City, Nagano Prefecture, Japan (hereinafter, “U Group”), where it will start operation.

Toshiba ESS’s pure hydrogen fuel cell system H2Rex^TM was installed as a fuel cell system at the “Hydro Q-BiC” at SHIMIZU CORPORATION’s (hereinafter, “SHIMIZU”) building-attached hydrogen energy utilization system, which supplies electricity to the U Group head office building. This will be the first building in Nagano Prefecture^*1 to use hydrogen energy, contributing to the Net Zero Energy Building (“ZEB”) initiative.^*2

H2Rex^TM is a more environmentally friendly pure hydrogen fuel cell that generates power and heat free of CO₂ emissions, and Toshiba ESS has already delivered H2Rex^TM to wholesale markets, convenience stores, heated swimming pool facilities, factories, and various other applications. While Hydro Q-BiC is installed outdoors, where the temperature is expected to be below 0°C in winter, Toshiba ESS has improved the design of the H2Rex^TM to achieve an installation temperature of -10°C and a power generation temperature of -7°C, enabling it to be used in lower temperatures than the previous product.

SHIMIZU has been promoting the introduction of Hydro Q-BiC, which contributes to low-carbon technology. The first Hydro Q-BiC unit has been operating since July 2019 in the wholesale market in Koriyama City, and all Hydro Q-BiC units are equipped with Toshiba ESS’s H2Rex^TM.

Shigehiro Kawahara, Vice President of the Energy Aggregation Div. at Toshiba ESS, says, “In order to help make a carbon-neutral society a reality, Toshiba ESS aims to provide high value-added hydrogen solutions by integrating related technologies, such as renewable energy-derived hydrogen energy, by expanding our business through this collaboration.”
