It is often stated that tanks cannot be used to store E15, but this assumption is incorrect as the majority of installed tanks can store blends above E10.
The American Coalition for Ethanol recently launched a tool at flexfuelforward.com to provide retailers with a free way to check if their equipment is already E15 compatible. Available 24/7, the “Flex Check” E15 compatibility tool will arm retailers with the confidence and information they need to make a conversion all in one place.
The Flex Check compatibility tool uses National Renewable Energy Lab (NREL) studies and ACE’s research with equipment companies to give retailers a place to enter the manufacturer or model of tanks, piping, and other equipment they have on site, and find out if they are already E15 compatible.
“Some stations owners will be able to download documentation they need to provide EPA if they decide to sell E15,” Lamberty added, “and if they’re not ready to sell E15, this tool will help them identify parts of their system that need to be replaced, and most retailers will be surprised at how cost effective adding E15 can be.”
The below white paper addresses the compatibility of E15 (15% denatured ethanol, 85% gasoline blendstock) with equipment at refueling stations. Over the last decade, a tremendous amount of work by refueling equipment manufacturers, industry groups, and federal agencies has resulted in a long list of equipment that can be used with E15. This report addresses compatibility through a literature review, a summary of applicable codes and standards, review of equipment manufacturer products, and verification with manufacturers regarding which ethanol blends work with their products. Over time, the refueling equipment manufacturers have improved their sealing materials for compatibility with a wide range of fuels. Upgrading materials in equipment improves consumer safety and reduces the risk of releases to the environment.
