The transportation industry is witnessing a growing interest in hydrogen internal combustion engines (ICE) and hydrogen fuel cell technology as alternative fuel options. Industry experts from Volvo Group, Cummins, and Bosch highlighted the potential of hydrogen ICE at the Advanced Clean Transportation Expo and Conference in Anaheim, California. They emphasized that hydrogen ICE shares commonalities with traditional diesel and natural gas engines, making it easier for fleets to adopt this technology. Hydrogen ICE technology is seen as particularly suitable for long-distance haulage, regions with limited access to sustainable fuels, and situations where quick recharging is necessary. Additionally, hydrogen ICE is considered a zero-emission technology, especially in the European market. Volvo Group is actively testing green and blue hydrogen in combustion engines and plans to begin low-volume hydrogen ICE production in Europe. Cespira, a joint venture involving Volvo Group and Westport Fuel Systems, is developing high-pressure direct injection technology to facilitate the use of hydrogen in internal combustion engines without significant modifications. The speakers at the expo highlighted that hydrogen ICE is not merely a transition to fuel cell technology but rather a complementary alternative offering flexibility to operators. They emphasized the importance of having multiple fueling options to cater to diverse operational needs. Overall, the sentiment towards hydrogen ICE in the article is positive, showcasing its potential as a fast-to-market, sustainable solution for future transportation challenges.
