Study shows relative CO2 savings of ethanol versus TAEE
A refinery model simulation study carried out by Hart Consulting shows that blending TAEE (tertiary amyl ethyl ether) into European gasoline results in an larger CO2 reduction than directly blending the ethanol.
When ethanol is used at 5%vol in all European gasoline, there is a calculated reduction in CO2 emissions of 700,000 tons per year versus a base case of no ethanol. When the ethanol is blended as TAEE, the calculated reduction in CO2 emissions versus the base case rises to 3,830,000 tons per year.
