Hydrogen engines are gaining traction as a promising alternative to traditional engines, particularly in industries like aircraft and long-haul vehicles where battery technology may not be feasible. The University of Michigan and the University of California, Riverside, along with other stakeholders, have formed the H2EA-NA to promote hydrogen engine development and infrastructure in the US. The focus is not only on the technology itself but also on ensuring that the hydrogen used is sourced from renewable sources. Global collaborations, such as Yamaha and Caterham in Japan developing Project V for an electric sports coupe, and BorgWarner partnering with Chinese brands for electric motors, are further examples of the industry's dedication to sustainable transportation innovations. These partnerships highlight a shift towards prioritizing sustainability and showcasing the potential for a carbon-neutral world in the future.
