Even with progress in electrifying passenger cars, the transport sector remains heavily dependent on conventional fuels. The shift to alternative fuels faces several obstacles: differing levels of technology readiness, inadequate infrastructure, higher costs than traditional fuels, and regulatory and market uncertainties. Nevertheless, a variety of transitional and alternative fuel options such as natural gas, biofuels, and synthetic fuels are available. Organisations that embrace these fuels early can benefit from first-mover advantages, government incentives, and improved sustainability profiles.
