Biofuels Versus Diesel and Gasoline in the JEC-WTW Report Version 2c - An Extract from the 'Well-to-Wheels Analysis of Future Automotive Fuels and Powertrains in the European Context', Ver. 2c March 2007

摘要

An extract of the JRC-EUCAR-CONCAWE (JEC) Well-to-Wheels Report (WTW) Version 2c, March 2007 has been made to form an easily readable reference for people interested only in biofuels.Thus, among all alternative fuels analysed in the WTW study, only the biofuels have been extracted. Conventional fuels, namely standard gasoline and diesel, have been incorporated for comparison.In particular, the following biomass types are considered:¿Sugar beet, sugar cane, wheat and straw (to ethanol and further conversion from ethanol to ETBE (Ethyl-Tertiary-Butyl Ether))¿Oil seeds -rapeseed, sunflower- (to bio-diesel)¿Wood (to ethanol and to synthetic liquid fuels)¿Organic wastes (to compressed biogas)The extract incorporates the complete pathway of the biofuel, from the production of the raw material to the final biofuel use in the car. It means to have listed in the report for each biofuel:¿availability in EU at given cost¿costs involved in the processing, transportation, infrastructures¿GHG emissions and energetic balance.Natural gas sources, hydrogen, fossil fuels and uses to electricity are not part of this report.
