Goal
Evaluate the safety and reliability of operating internal combustion engine (ICE) vehicles on hydrogen and blended HCNG fuels; Develop a working model of a refueling system for ICE and fuel cell vehicles
Description
The plant's hydrogen system consits of production, compression, storage and dispensing. It distinctly separates the hydrogen ystem from the natural gas system, but can blend the two fuels at the stationary filling system. Components: Hydrogen Generator – PEM fuel cell, 57 kW, 300 scfh hydrogen output (Hogan 300) Hydrogen Compressor – Oil free, three stage, diaphragm compressor, 99.9997% purity Hydrogen Dispenser – Dispenses hydrogen up to 5,000 psi HCNG and CNG Dispenser – Dispenses HCNG and CNG up to 3,600 psi CNG Boot Compressor – 300 scfm @ 60 psi CNG Main Compressor – 350 scfm @ 4500 psi CNG Storage – 50,000 scf up to 5,000 psi Fuel Dispenser – Pure hydrogen or CNG and HCNG blended fuels, with metering and electronic billing interface
