Future perspectives for biofuels in road transport

The promotion of biofuels is a political priority and part of the European energy-climate policy. The EC Directive 2009/28/EC on the promotion of the use of energy from renewable sources introduced a binding target of 10 % share of renewable energy in transport by 2020. For this target, biofuels will make a substantial contribution. In addition, Directive 2009/30/EC allows for the blending of ethanol into petrol up to 10 % (v/v) and for a FAME content of 7 % (v/v) in diesel.
In 2013, the European Parliament stated its intention to place a 6 % cap on first-generation biofuels and a 2.5 % incorporation threshold of advanced biofuels, produced from waste or algae, but these initial ambitions were cut down in the draft directive on the change of land use (June 2014). This agreement imposes a minimum level of 7 % of final energy consumption in transport in 2020 for first-generation biofuels and does not provide for a binding incorporation target for advanced second and third generation biofuels. The agreement is still in a draft version, a final decision is expected for 2015 (EurObserv’ER 2014).
Future expansion of biofuels in road transport up to 2020 and beyond depends on a favourable regulatory environment for advanced biofuels value chains, in particular to support:
·   availability of more diverse feedstocks including energy crops, wastes and residues
· demonstration of innovative thermochemical, biochemical and chemical conversion technologies at commercial scale
·  market development of advanced biofuels through support mechanisms at national and EC level
Global expansion of biofuels use in road transport also depends on the ongoing development of:
·   CI and DI engines able to use higher blends of ethanol and diesel

· the development of drop-in biofuels with properties 'near-identical' to their fossil fuel counterparts. Drop-in fuels can be used in standard engines at much higher blend levels than conventional biofuels, or even at 100% with similar performance.
