Toyota has introduced its latest third-generation hydrogen fuel cell technology at the H2 & FC Expo in Tokyo, Japan. The new fuel cell system, targeted at commercial use, boasts enhanced performance, fuel efficiency, and cost-effectiveness, making it comparable to conventional diesel engines. While the technology will also be utilized in passenger vehicles, Toyota suggests that the future market for personal cars is unlikely to focus on hydrogen due to limited sales and infrastructure challenges. Toyota's commitment to hydrogen for long-term carbon neutrality remains steadfast, with the new fuel cell set for markets in Japan, Europe, North America, and China post-2026. This third-gen fuel cell aims to address the shortcomings of its predecessor by offering increased durability and a 20% increase in cruising range, positioning it as a viable alternative to diesel engines in commercial vehicles. Toyota's success in supplying fuel cells for buses, trains, and power generators is encouraging for the new technology's potential in meeting the company's fuel-cell needs in the commercial sector, particularly in creating 'hydrogen societies' in partnership with various industries.
