- Biomass-derived biofuels can aid in rapidly decarbonizing the transportation industry by replacing diesel fuel in heavy-duty vehicles. While the electric vehicle (EV) share of the light-duty fleet has grown rapidly, medium- and heavy-duty vehicles present an electrification challenge because of their high energy-density requirements. Biomass-derived biofuels have high energy densities, combust with fewer tailpipe green-house gas (GHG) emissions compared to petroleum-derived diesel, and can replace heavy-duty fuels without major changes to vehicle design and fueling infrastructure. To achieve both high fuel efficiency and low tailpipe GHG emissions with biofuels, their properties must be well understood. One such property, the heat of vaporization (HOV), represents the energy required to vaporize a liquid on a per-mole basis and is important for the fuel injection event of the compression ignition cycle. In this research, the HOVs of various novel diesel-like biofuels were determined using a combined differential scanning calorimetry and thermogravimetric analysis (DSC/TGA) and DSC only approach. The results showed a high repeatability of experimental HOV analysis. Finally, this procedure for determining the HOVs of biofuels showed promise as part of a multi-tiered screening of potential candidates to replace conventional diesel with a more sustainable alternative fuel.
