Liquid biofuels offer an alternative fuel for all types of internal combustion engines currently running on gasoline, diesel, or kerosene. Potential exists for passenger vehicles, trucks, ships and airplanes. REmap shows that liquid biofuels, including both conventional and advanced forms of ethanol and biodiesel, could account for 10% of transport-sectorenergy use by 2030, more than triple the share today.
Liquid biofuels will be key if the transport modes of shipping and aviation are to be made more sustainable. These modes make up 20% of transport energy demand, and are the fastest growing segments of any part of the transport sector. Therefore solutions, in particular for advanced biofuels, will need to be developed.
Advanced biofuels offer significant emission reductions compared to the petrol or diesel.
For advanced biofuels, technology commercialisation and lack of investments in production capacity are the main barriers that should be overcome
