A review of techno-economic data for road transportation fuels

Worldwide, the road transport sector typically arises as one of the main sources of air pollutants due to its high energy intensity and the use of fossil fuels. Thus, governments and social agents work on the development and prospective planning of decarbonisation strategies oriented towards sustainable transport. In this regard, the increase in the use of alternative fuels is the recurrent approach to energy planning, e.g. through the promotion of electric vehicles, biofuels, natural gas, liquefied petroleum gas, etc. However, there is a lack of comprehensive information on the techno-economic performance of production pathways for alternative fuels. The acquisition of robust techno-economic data is still a challenge for energy planners, modellers, analysts and policy-makers when building their prospective models to support decision-making processes. Hence, this article aims to fill this gap through a deep literature review including the most representative production routes for a wide range of road transportation fuels. This led to the development of datasets including investment costs, operating and maintenance costs, and transformation efficiencies for more than 40 production pathways. The techno-economic data presented in this work are expected to be especially useful to those energy actors interested in performing long-term studies on the transition to a sustainable transport system.
