Although it is claimed by many that hydrogen technology is a dead-end, Japan will be showing off some of its hydrogen-based gadgets at the Osaka Expo in 2025:

Iwatani Corporation has completed the construction of a hydrogen-powered boat poised to ferry passengers to and from the 2025 Osaka Kansai Expo. This groundbreaking vessel will mark Japan's first commercial operation of a hydrogen-powered boat. The company plans to commence test operations shortly and aim for full service during the Expo, which begins in April 2025. The ship, Mahoroba, which in ancient Japanese translates to "a comfortable place to live," embodies the company's vision of a sustainable future. The 33-meter-long, 8-meter-wide vessel is designed to accommodate 150 passengers. Its propulsion system utilizes hydrogen fuel cells, generating electricity by reacting hydrogen and oxygen from the air. This innovative technology offers a clean and environmentally friendly mode of transportation, aligning with global sustainability goals.

It doesn't emit carbon dioxide during operation, and produces less odor, noise and vibration than traditional boats powered by gasoline engines. The Mahoroba was built in Onomichi, Hiroshima Prefecture, and a launching ceremony was held in May. It was then towed by another ship to Osaka in mid-October. The operation of the vessel will be entrusted to Osaka Aqua Bus ltd., a wholly owned subsidiary of Keihan Holdings Co.



Another hydrogen-based invention to be displayed in Osaka:

Coca-Cola Bottlers Japan Inc. and Fuji Electric Co., Ltd. will unveil the world's first vending machine powered by hydrogen cartridges at Expo 2025 in Osaka. This groundbreaking vending machine represents a significant step towards a more sustainable future, as it utilizes hydrogen as an alternative energy source to reduce carbon emissions and contribute to the goal of achieving carbon neutrality by 2050. Unlike traditional vending machines, this innovative device is unaffected by weather conditions or location and emits no CO2 during operation. It will be showcased at Expo 2025 Osaka, Kansai, a worldwide platform for showcasing advanced technologies. Visitors to the Expo will have the opportunity to experience this futuristic vending machine firsthand.
