Propagation of alternative vehicle worldwide
• Micro hybrids offer 3-4% CO2 reductions, mild hybrid up to 12% and full hybrids up to 20%. IC Engine and transmission improvement Petroleum (conventional sources) 100 % 65 % 40 % 20 % 3 % 0 % 1995 2002 2010 2015 2020 Fuel Cell Vehicle Fuel cell • Fuel cells and pure electric propulsion technologies impact long term, both being zero emission technologies. However the source of electricity is to play a major role in the future. Battery electric Vehicle Electricity Full, mild and micro hybrids Bio fuel (Ethanol, Bio-diesel) • Plug in hybrids could offer as much as 65% CO2 reductions depending on the customer driving characteristics, is seen as a midterm solution. Plug in hybrids Hybrid (conventional + Elec.) • The future of bio fuels pose a challenge with its own share of controversies regarding harvesting of crops.

Conclusions Conclusions: M. Mourad 29.10.2014 slide # 11
Alternative fuels in developing countries have been driven by air pollution, balance of payments/import dependence concerns, industrial development aspirations (and increasingly greenhouse gas concerns). There are significant alternative fuel programms in developing countries to learn from (including those that require new infrastructure for CNG and LPG). Alternative fuels programms develop around local energy sources rather than fuel imports. Cost advantages are often location specific. Successful alternative fuels in vehicle are based on social /political actions. M. Mourad slide # 11
