SERC has successfully installed and commissioned the 700 bar hydrogen fueling system at the Humboldt State University (HSU) Hydrogen Station. The first 700 bar hydrogen fueling of a Toyota FCHV-advanced vehicle took place on October 25, 2012 during testing operations with engineers from Toyota.
The 18-month project was supported by a grant from the California Department of Transportation entitled, “Developing a Hydrogen Transportation Infrastructure.” With the new fueling system, the station can now completely fuel state-of-the-art vehicles, such as the Toyota FCHV-advanced vehicle, to 700 bar. This high pressure fueling capability now connects the HSU station with the rest of California’s Hydrogen Highway.
The new fueling system required the installation of a 700 bar compressor and dispensing hardware to allow full fueling of vehicles. The compressor pumps hydrogen from the existing 420 bar storage tanks through the dispensing plumbing and directly into the vehicle’s fuel tanks.
Data collection and analysis has started and will continue in order to evaluate the 700 bar fueling system and vehicle performance in day-to-day use. Through this continued operation and evaluation, SERC will contribute to the technical experience needed in the development of a hydrogen transportation infrastructure and also assist in public acceptance of this alternative fuel technology in California.
