Abstract | One approach being put forth for the advancement of hydrogen fueled vehicles is to blend hydrogen with compressed natural gas (H/CNG) for use in state-of-the-art internal combustion engine vehicles. Current natural gas engines and vehicles can be modified to operate on H/CNG with available technology. This report reviews a small-scale study of this concept. The project demonstrated that with minor engine and vehicle modifications, the 20/80 hydrogen/CNG blend can be used in revenue service fleets with similar operational performance as CNG. However, additional optimization of the H/CNG engine calibration is necessary to attain equivalent fuel economy, or alternatively increased fuel economy at equivalent NOx emissions. |
