The California Air Resources Board (CARB) has released the 2023 issue of its Annual Evaluation of Fuel Cell Electric Vehicle Deployment and Hydrogen Fuel Station Network Development, pursuant to the requirements of Assembly Bill 8 (2013). This report is the tenth annual publication. The 2023 and previous reports are available at CARB’s Hydrogen Fueling Infrastructure page (see the “2023 Report” link). 

The Annual Evaluations provide CARB’s latest assessment of California’s on-road fuel cell electric vehicle fleet, auto manufacturer projections for future deployment volumes in California, and progress in development of California’s hydrogen fueling station network.
