Abstract
The “Controlled Hydrogen Fleet and Infrastructure Demonstration and Validation Project,” also known as the National Fuel Cell Electric Vehicle Learning Demonstration, is a U.S. Department of Energy (DOE) project started in 2004 and concluded in late 2011. The purpose of this project was to conduct an integrated field validation that simultaneously examined the performance of fuel cell vehicles and the supporting hydrogen fueling infrastructure. The DOE’s National Renewable Energy Laboratory (NREL) received and analyzed all of the raw technical data collected by the industry partners through their participation in the project over its seven-year duration. This paper reviews highlights from the project and draws conclusions about the demonstrated status of the fuel cell vehicle and hydrogen fueling infrastructure technology. Through September 2011, 183 fuel cell electric vehicles were deployed, 25 project fueling stations were placed in use, and no fundamental safety issues were identified. We have analyzed data from more than 500,000 individual vehicle trips covering 3.5 million miles traveled and more than 150,000 kg hydrogen produced or dispensed. Public analytical results from this project are in the form of composite data products (CDPs), which aggregate individual performance to protect the intellectual property and the identity of each company while still publishing overall status and progress. Ninety-nine of these CDPs have been generated for public use and posted on NREL’s technology validation website. The results indicate that fuel cell vehicle technology continues to make rapid progress toward commercial readiness and that the fueling infrastructure technology is ready to provide a consumer-friendly fast fill and long range experience consistent with expectations of gasoline vehicle customers.
Highlights
IntroductionThe industry partners provided their final project data to National Renewable Energy Laboratory (NREL) in October 2011 and we have performed analysis across the entire seven-year period
This paper discusses key analysis results based on data from early 2005 through September 2011 from the U.S Department of Energy’s (DOE’s) Controlled Hydrogen Fleet and Infrastructure Validation and Demonstration Project, referred to as the National Fuel Cell Electric
The Learning Demonstration project was the largest single fuel cell vehicle and hydrogen infrastructure demonstration in the world to date, and the first time such comprehensive data were collected by an independent third party and consolidated and analyzed for public dissemination
Summary
The industry partners provided their final project data to NREL in October 2011 and we have performed analysis across the entire seven-year period. During this time, 183 fuel cell electric vehicles were deployed, 25 project fueling stations were placed in use, and no fundamental safety issues were identified. Key objectives of the project were to evaluate fuel cell durability, vehicle driving range, and on-site hydrogen production cost This evaluation was performed through validating the use of FCEVs and hydrogen fueling infrastructure under real-world conditions using multiple sites, various climates, and a variety of hydrogen sources. A final comprehensive report is scheduled to be published in April 2012
