Yusuke Nagai, Hydrogen Energy Department, Iwatani Corporation, said, "The bicycle has a hydrogen cartridge and fuel cell inside. The hydrogen is sent to the fuel cell, and the electricity that is produced is then used to provide the power to assist pedaling."

The 80 liter hydrogen cartridge powers the bicycle for about three hours before it has to be refilled, which is done at the airport's hydrogen refueling station.

The largest benefit of using hydrogen as an energy source for the bicycles is that they are 100 percent environmentally friendly. The fuel cell's only emission is pure water without any gases, which rules out pollution or possible greenhouse gases.
