At the International Hydrogen Fuel Cell Vehicle Congress and Exhibition in Shanghai, over 300 companies highlighted the growing interest in hydrogen vehicles, touted as the future of net-zero transport. These vehicles operate using electricity produced from hydrogen by fuel cells, presenting a sustainable alternative with zero emissions beyond water vapor. The article discusses the advantages of hydrogen vehicles, including quick refueling times and extended driving ranges, citing Toyota's Mirai as a standout model. However, challenges like limited green hydrogen availability, slow infrastructure progress, and higher costs and inefficiency compared to battery electric vehicles pose obstacles to mass adoption. The article touches on the global landscape of hydrogen vehicle adoption, with Korea, China, and the US leading registrations. Countries are exploring ways to make hydrogen vehicles more accessible and cost-effective, aiming to compete with traditional diesel vehicles in the future.
