Overcoming Cultural Bias Against Corn Ethanol New DOE BETO FOA specifically allows grain starch Cost < $2.50 , Demonstrate 70% GHG reduction.

© Whitefox Technologies Limited 2021Vital Role for Corn Starch Ethanol in “Zero Carbon” Transportation
Is Corn Starch Ethanol the Best Renewable Fuel? Probably, Yes
Carbon-Reducing Technologies required for other Fuels Pathways to achieve Ultra-
Low / Zero Carbon Scores are Same Technologies being implemented in Corn
Starch Ethanol
Corn Starch Ethanol Production is already Well-Established Processes and
Agricultural and Transportation Fuel Commerce.
With Reality-Based Adjustments to CI models for Farm Inputs, LUCs and ILUCs,
Corn Starch Ethanol is likely at a Permanent Advantage on Cost to Produce,
Efficiency, and CI.
Corn Starch Ethanol is a Practical Way to Decarbonize Transportation,
Support U.S. Farming, and offer Best Price and Air Quality Benefits to U.S. CitizensWhitefox Technologies – Introduction

Conclusions
• A Producer can develop a strategy to implement existing technologies into their corn
ethanol plant, in various combinations, to achieve ultra-low or zero CI in the next five
years
• Corn farming practices and realistic corrections into land-use change modeling
accelerate that
• Whitefox offers a low-risk path for debottlenecking, reducing energy use and optimizing
operations
• Incremental expansion steps over the next five years can significantly reduce natural gas
use and replace molecular sieve units (Whitefox ICE®-XL). It starts with Whitefox ICE®
