"The use of vegetable oils for engine fuels may seem insignificant today, but such oils may become in the course of time as important as the petroleum and coal tar products of the present time.“ - Rudolph Diesel, 1912
"The fuel of the future is going to come from fruit like that sumac out by the road, or from apples, weeds, sawdust - almost anything. There is fuel in every bit of vegetable matter that can be fermented. There's enough alcohol in one year's yield of an acre of potatoes to drive the machinery necessary to cultivate the fields for a hundred years.“ - Henry Ford, 1925
Based on the historical rate of hybrid electric vehicle (HEV) growth as a benchmark for the first 10 years, and realistic technology sales growth projections by 2020 based on known technical and infrastructure challenges
• Charge Sustaining Electric Drive Vehicles:– Today’s HEVs– No ability to connect to grid– All energy comes from on-board chemical fuel
• Charge Depleting Electric Drive Vehicles:– PHEVs and EVs– Require or expected to be connected to grid– For PHEVs, energy is mix between on-board chemical fuel and
electricity
• The latter category requires a more in-depth approach for evaluating the impact
• Charge depleting electric drive vehicles can offer major gains in petroleum usage and greenhouse gas emissions– Certain regulated emissions can increase from
conventional vehicles– Generation mix, time of charging events, and vehicle
driving patterns all impact environmental impact
• Charge sustaining electric drive vehicles (i.e. today’s conventional HEVs) offer more modest improvements in petroleum and GHG with no increase in regulated emissions
