HOUSTON (ICIS)--Butamax Advance Biofuels announced on Friday that a joint research project with Underwriters Laboratories (UL) has determined that gasoline fuel storage and dispensing equipment meeting UL standards can use blends containing up to 16% isobutanol that is derived from biomass.
Butamax stated that the guidance from UL clears the way for state regulatory agencies to consider and approve dispensing isobutanol gasoline blends.
Butamax bio-based isobutanol is not yet commercially available. The company recently began work on the first phase of a retrofit of the Highwater ethanol plant in Lamberton, Minnesota, including the installation of a feed train and processors at the facility. The company expects to be commercially producing isobutanol by 2015.
Butamax is a joint venture between BP and DuPont.
Other groups are also working on commercial production of isobutanol and n-butanol from biomass in the US.
In September, Green Biologics agreed to acquire the Central MN Ethanol Co-op (CMEC) in Little Falls, Minnesota, with plans to use the C-MEC plant to produce n-butanol.
Gevo brought a second fermenter on line at its isobutanol plant in Luverne, Minnesota, during the summer.
Abengoa Bionergy is also looking to produce industrial butanol in 2015.
