This data-file compares different trucking fuels — diesel, CNG, LNG, LPG and Hydrogen — across 35 variables. Most important are the economics, which are fully modelled.
Natural Gas can be close to competitive. On an energy-equivalent basis, $3/mcf gas is 4x more economical than $3/gal diesel. However, the advantages are offset by higher vehicle costs, operational costs and logistical costs. Overall, CNG ends up 10% more expensive, and LNG ends up 30% more expensive versus diesel-trucking. Mild environmental positives of gas are also offset by mild operational challenges.
Hydrogen still screens as an expensive alternative. We estimate vehicle costs are 2x higher than diesel trucks, while $15/kg hydrogen is 4x more expensive than diesel as a fuel.
