The U.S. Green Hydrogen Market for Mobility is experiencing a significant uptick driven by federal policy support and investments in infrastructure. The Inflation Reduction Act and advancements in electrolyzer technologies, particularly PEM and alkaline types, are boosting green hydrogen production from renewable sources like wind and solar. Key industry players such as Plug Power, Cummins, Linde, Air Liquide, and Bloom Energy are laying the groundwork for a scalable hydrogen mobility ecosystem. The market is witnessing growth in adoption trends across various sectors, including passenger FCEVs, commercial trucks, buses, marine, and aviation applications. Policy measures like the Inflation Reduction Act, along with the development of regional hydrogen hubs, are expected to reduce green hydrogen costs, enhancing its competitiveness with conventional fuels. By the early 2030s, large-scale projects in regions abundant in wind and solar resources are forecasted to supply cost-effective green hydrogen, promoting robust ecosystem growth catering to a wide range of mobility applications. Segmentation by application includes passenger FCEVs with a focus on expanding fuel cell models, commercial FCEVs like trucks and buses benefiting from rapid refueling and extended range, confined space equipment such as forklifts and cargo handlers improving productivity, hydrogen locomotives for lower-emission rail transport, marine applications from small ferries to larger vessels, and aviation including air-side vehicles relying on on-site electrolysis for fueling. Overall, the U.S. Green Hydrogen Market for Mobility is poised for substantial growth and innovation in the coming years.
