Fossil Fuels are currently classified as some of the leading producers of greenhouse gases which are major agents of Global warming. This study establishes the benefits Liquified Natural Gas (LNG) would have when used as a fuel in a hybrid-electric vehicle. The study establishes a Parallel-Hybrid vehicle model equipped with a control system to determine the mode of operation of the vehicle. Simulations using the vehicle models developed were performed in AVL Cruise. The results generated from the simulations the vehicle’s fuel consumption and CO2 emissions are compared to that of a traditional gasoline/diesel Internal Combustion Engine. The results show a lower acceleration time and better fuel consumption in the LNG hybrid vehicle operation. Further tests are needed to properly ascertain the CO2 emission and overall efficiency of the LNG hybrid vehicle model.
