Abstract

Abstract: Nowadays, the environmental problems caused by the burning of fossil fuels as vehicle fuel have become more and more serious in the world. Many countries are carrying out the research on the alternative energy sources and the clean energy. Meanwhile, China has begun to focus on the development of the gas mixture containing hydrogen as the vehicle fuel, mainly hydrogen enriched compressed natural gas (HCNG) and coke oven gas (COG). Application status of HCNG and COG as the vehicle fuel in China were reviewed and their existing problems were analyzed. The analysis results shows that the relevant regulations standards of HCNG vehicle, COG vehicle and their refueling stations have not been formulated and unified yet and the optimal hydrogen ratio of the HCNG requires further experimental investigation and theoretical analysis. In addition, as a country with substantial COG wasted, China can make better use of the wasted hydrogen contained in COG to realize the miniaturization and closed production of the COG without pollution. HCNG and COG as vehicle fuel are beneficial for the development of the hydrogen energy, which can alleviate the crisis of global energy shortage and effectively reduce the production and emission of sulfur oxides. Therefore, the prospects of HCNG and COG as the vehicle fuel are good in China. Highlights: Vehicle standards of HCNG and COG have not been formulated and unified. Refueling stations standards of HCNG and COG have not been formulated. Optimal hydrogen ratio of HCNG requires further study. Miniaturization and closed production of COG can make better use of COG.
