with costs and investments in AF infrastructure, as well as the limited economic viability of biofuel use in transportation. To address these issues, the authors of the report emphasize the need for developing a common European approach to the AF market and call on the European Commission to support a detailed assessment of policymaking. They also recommend strengthening the regulatory framework by identifying clear long-term objectives as well as offering financial incentives.
Other strategies and suggestions include: improvements in truck and powertrain design; technology neutrality for the combination of various fuel alternatives; and the progressive use of AF technologies—starting with more mature ones. The authors propose "switching from Diesel to Compressed Natural Gas and Liquified Natural Gas (for heavier trucks and longer routes) and progressively to Advanced biofuels, Bio-Methane, Synthetic gas and, ultimately, Hydrogen" where electric-based solutions are unfeasible.
Increased efficiency
The ongoing COLHD (Commercial vehicles using Optimised Liquid biofuels and HVO Drivetrains) project was launched to develop an AF engine that's more efficient than the standard diesel alternative. COLHD covers technology, infrastructure and removal of additional barriers. It focuses on the development of three powertrain technologies that use biogas (liquefied biomethane or liquid biopropane) and second-generation biofuels (hydrogenated vegetable oil). The project website states: "The engines will be designed to run on optimized blends of both fossil fuels, mainly Autogas (LPG) and LNG (Liquid Natural Gas), and non-fossil renewable biofuels, with the objective of progressively increasing the share of biofuels throughout the evolution of the market." In addition to conducting research on removing barriers and reducing costs across the whole value chain, project partners have made significant progress in fuel selection.
