Movement of freight is a major factor of the economy, while diesel truck hauling is not the primary method it is a major cost affecting the sales and distribution of goods. Over the past, few years alternative technologies have been developed that are proving to be strong competition to light and medium duty diesel trucks. These new trucks are powered by liquid natural gas (LNG), all electric, and diesel hybrid; this research paper will describe a truck from each category and conduct economic analyses using variable energy prices, minimum attractive rates of return (MARR), miles traveled per year, and discounted upfront purchase costs. Under these different scenarios, the economic analysis shows that alternative fueled trucks can compete with diesel. Issues, which may arise in a broader technology analysis, may find that the infrastructure and technology is still developing, as in the distribution network for liquid natural gas and battery systems.
