• Product Attributes– Adaptability– Burning Attributes– Octane
• Product Challenges– Energy Density– Current Engine Technology
• New Applications– E100 – proven fuel in Indy Cars
Ethanol Technology• Ricardo’s EBDI Engine – the future
– Ethanol Boost, Direct Injection– 3.2 L engine to replace 6.6 -7 L CI engine to
deliver peak power 450+ hp, 663 lb-ft torque at 3000 rpm More horsepower and torque than
gasoline Diesel engine replacement Closes the gap in fuel economy Meets new US EPA emissions stds

• US Market Biofuels– 36 Billion Potential– >25% volumetric replacement
• National Security– Cost of Oil (USD)
• Environment– Total GHG Reduction
• Rural Development (Jobs)– Green Jobs Waiver (E15)– 136,000 new jobs– US$24 billion/year to GDP– One Time GDP Impact
• US$37 billion in capital projects• 260,000 jobs
