This is one article in a series that discuss key findings from a newly completed market and competitive economic analysis of ten potential alternative fuels for commercial vehicles. The analysis covered natural gas in both compressed (CNG including Bio-methane) and liquefied (LNG) forms, liquid propane gas (LPG a.k.a. Autogas), dimethyl ether (DME), Hythane®, hydrogen in both compressed and liquefied forms, (bio)ethanol, biodiesel, and methanol. Each of these fuels becomes competitive at different oil/diesel prices in each of the four global regions; North America, Latin America, Asia-Pacific, and EMEA (Europe, Middle-East, and Africa). This exercise has uncovered valuable insights and profitable opportunities for all the stakeholders in this exciting emerging sector.
