Bio-Isobutanol Wins Key Thumbs-up from Underwriters Labs

by Jim Lane (Biofuels Digest) In Illinois, Underwriters Laboratories announced a joint research program has determined that gasoline fuel storage and dispensing equipment meeting latest UL standards can safely and successfully use blends of up to 16% biobutanol. This is the first time that UL has made such a determination.
According to UL: “fuel storage and dispensing products intended to handle isobutanol-gasoline blends, up to 16 percent isobutanol by volume and compliant with applicable ASTM International fuel quality standards, will not require special investigation by UL if they have been Listed for use with applicable UL standards that require testing with 25% or higher ethanol blends.
“This includes fuel dispensing equipment Listed to the UL Subject 87A Outline of Investigation for Power-Operated Dispensing Devices for Gasoline and Gasoline/Ethanol Blends with Nominal Ethanol Concentrations up to 85 Percent (E0 – E85).”

State regulations require fuel dispensing equipment to be listed by independent product safety testing laboratories such as UL.
This ruling provides assurance to all of the service stations that the fuel will work fine in their current equipment without the need to purchase new pumps. This removes another hurdle to be able to full market renewable isobutanol in on road gasoline.
At the time current UL dispensing equipment test standards were finalized, biobutanol was not commercially available and was not tested. This announcement by UL means that if butanol had been available as a fuel it would have been included for service use in equipment meeting latest UL standards. READ MORE and MORE (UL)
