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.
