City-Tech.Tokyo:Technical Tours Showcasing Tokyo's Futuristic Approach to Urban Development

The City-Tech.Tokyo conference was held at the Tokyo International Forum from February 27 to 28, 2023, to great success. This conference is dedicated to making a "sustainable society through open innovation with startups," and this time, explored this concept through the four themes "infrastructure," "environment," "living," and "culture." The event was held in a hybrid format and attracted a total of 26,000 delegates and various speakers, including Japan's most famous architect Kengo Kuma and the governor of Tokyo.

Tokyo Convention & Visitors Bureau (TCVB) provided in-kind half-day technical tours of Tokyo for foreign delegates, in line with the conference's content, maximizing educational opportunities for participants and showcasing Tokyo's futuristic approach to urban development. Below we introduce two of the highlights.

Technical Tour on Hydrogen Boat "Hydro Bingo"

On February 28, participants of City-Tech.Tokyo had an exceptional opportunity to join the technical tour on the unique hydrogen-powered boat Hydro Bingo, which uses H2 as fuel for propulsion. This is the world's first passenger ferry of its kind.

Hydro Bingo is a 19.4m long aluminum alloy catamaran type equipped with two dual-fuel engines utilizing diesel and hydrogen. It can accommodate 80 passengers and can cruise at a maximum speed of 26.0 knots.

This eco-ship was developed by Tsuneishi Facilities&Craft Co.Ltd. in Hiroshima Prefecture jointly with the Belgian shipowner Compagnie Maritime Belge (CMB.TECH), which has extensive know-how in marine hydrogen systems aim to decarbonize ships. The ferry is currently operated by a start-up company named JPNH2YDRO Co., LTD. The ship's name refers to" Hydro," the Greek word for water, and "Bingo," the former region comprising the eastern part of Hiroshima Prefecture today.

An amazing tour started from Hinode Pier with JPNH2YDRO's explanation about the boat's safety. The hydrogen storage tank is located on the stern (the back part of the boat) and equipped with H2 gas detectors. There is also a thick wall between the tank and passenger cabin to secure extra protection for travelers. Japan Craft Inspection Organization approves the safety of the ship.

The H2 injection system requires minimal changes to the base engine. It was highlighted that Hydro Bingo drastically cuts CO₂ emissions by up to 50% during navigation using a mixture of diesel/hydrogen fuels compared to conventional diesel engines. Test results related to CO₂ emission reduction were displayed on the monitoring screen. Participants could also see on the monitor the bars of diesel fuel and hydrogen ratio beside usual indicators of engine speed, the distance from the port, and other data. It was stressed that the H2 dual fuel system is designed to control and allow automatic switch back over to diesel-only operation, ensuring the machine's operational reliability in case of any problem. Participants were also very impressed that hydrogen supply was much easier to implement than they expected.

After the explanation, participants enjoyed guided views of the Rainbow bridge, Odaiba seaside area, Tokyo International Cruise Terminal, the Olympic and Paralympic village, and other spots from the upper open deck. Tokyo weather welcomed all travelers with an exceptionally warm and sunny day. All participants highly evaluated the rare content of the technical tour where they could experience the future of boats.

Digital Technology the Future of Offices: Mori Building and CIC Tokyo
