Toshiba Corp says its “H2One” stand-alone hydrogen energy supply system has been completed in the “Henna (Weird) Hotel,” a hotel run by Huis Ten Bosch Co Ltd in Sasebo City, Nagasaki Prefecture.
The Henna Hotel is known for its robot reception staff and is located in an area adjacent to the Huis Ten Bosch theme park. The H2One was introduced in the “West Arm” building, which was constructed in the second construction phase.
The H2One is a CO2-free stand-alone hydrogen energy supply system that is based on Toshiba’s unique hydrogen EMS (energy management system) and uses renewable energy and hydrogen to stably supply electricity. It consists of a solar power generation system, storage battery, hydrogen production equipment, hydrogen storage alloy tank and pure hydrogen fuel cell.
In summer, when there are long hours of sunlight, surplus solar electricity is used to electrolyze water with the hydrogen production equipment, and the produced hydrogen is stored in the tank. In winter, the stored hydrogen is used to generate electricity with the pure hydrogen fuel cell. As a result, one hotel building (12 rooms) can be powered by using only water and solar power throughout the year.
