This purpose of this report is to document and discuss key results to date from the U.S. Department of Energy's (DOE) Controlled Hydrogen Fleet and Infrastructure Validation and Demonstration Project, also referred to as the fuel cell vehicle learning demonstration. This report serves as one of many mechanisms to help transfer knowledge and lessons learned within various parts of DOE's hydrogen program, as well as externally to other stakeholders. The primary goal of this project is to validate vehicle/infrastructure systems using hydrogen as a transportation fuel for light-duty vehicles. This means validating the use of fuel cell vehicles (FCVs) and hydrogen refueling infrastructure under real-world conditions using multiple sites, varying climates, and a variety of sources for hydrogen.
