Japan's advancement in hydrogen and fuel cell (FC) technology goes beyond automotive use, as demonstrated by the operation of the Hanaria, the country's first hydrogen-powered passenger ship in Kitakyushu. The ship, equipped with hydrogen fuel cells similar to the Mirai, can utilize hydrogen, biodiesel, or a combination of both fuels, significantly decreasing CO2 emissions compared to traditional fossil fuel-powered ships. The report observes the challenges of refueling ships with hydrogen due to the lack of stations, showcasing innovative navigation systems resulting from collaborations between Toyota and other companies. Additionally, the H2 & FC Expo held in Japan featured diverse exhibits illustrating the broad spectrum of applications for hydrogen and FC technology, from water heaters to power generators, attracting international visitors. The article emphasizes the growing acceptance and utilization of hydrogen as a clean energy source, highlighting the efforts to establish partnerships and collaborations for a sustainable, carbon-neutral future.
