Greenhouse gas (GHG) emission, which has led to global warming and unpredicted climate change, remains one of the major challenges. Transport industry ranks second in the list of largest contributors to GHG emissions, with over 90% petroleum-based fuel usage. Clean transport brings the idea of low or zero tailpipe emission by reducing or eliminating non-renewable energy with the use of alternative fuels like solar, propane, biodiesel, hydrogen, non-fossil methane, electricity, non- fossil natural gas, biomass and ethane. Private fleets and government vehicles are the biggest shareholders in the global alternative fuel market followed by industrial transportation and domestic vehicles.
Propane, which has been widely used for decades, mainly for fleet applications such as school buses, shuttles and police vehicles, offers notable GHG emission benefits as compared to gasoline vehicles. In addition, ethanol is being blended with biodiesel, yielding higher energy output at lower emissions.
Clean transport sector is witnessing major change with the emergence of electric vehicles (EV) which provides both noiseless and low emission mobility. EVs can be segmented into All Electric, Plug-in Hybrid, Hybrid Electric Vehicles (HEV) and battery electric vehicle (BEV). Li-ion batteries are preferred choice for electrical vehicles; however cost is a major impediment associated with Li-ion batteries usage.
Electrical vehicles are gaining attention but the lack of proper charging infrastructure to support the usage of electrical vehicles remains a hurdle. Vehicle-to-grid connectivity can act as an appropriate solution for the problem which enables flow of power between a power system or grid and electric drive vehicles. Manufacturers like Nissan, Volkswagen, Tesla, BMW, General Motors and Ford already have their EVs running on roads.
Global initiatives and strict government policies to reduce carbon dioxide emissions will further drive the growth of clean transport sector.
