Madison-based Virent Energy Systems Inc. today announced it has launched a joint research and development effort with Shell to convert plant sugars directly into gasoline and gasoline blend components, rather than ethanol.
The collaboration could herald the availability of new biofuels that can be used at high blend rates in standard gasoline engines. Such a fuel could potentially eliminate the need for specialized infrastructure, new engine designs and blending equipment.
Virent's trademarked BioForming platform technology uses catalysts to convert plant sugars into hydrocarbon molecules like those produced at a petroleum refinery. Traditionally, sugars have been fermented into ethanol and distilled. The new biogasoline molecules have higher energy content than ethanol (or butanol) and deliver better fuel efficiency. They can be blended seamlessly to make conventional gasoline or combined with gasoline containing ethanol.
The sugars can be sourced from non-food sources such as corn stover, switch grass, wheat straw and sugarcane pulp, in addition to conventional biofuel feedstock like wheat, corn and sugarcane.
The companies have so far have agreed to collaborate for one year on the research. According to Virent, the BioForming technology has advanced rapidly, exceeding milestones for yield, product composition and cost. Future efforts will focus on further improving the technology and scaling it up for larger volume commercial production.
Dr. Randy Cortright, Virent's co-founder, chief technical officer and executive vice president, said, "Virent has proven that sugars can be converted into the same hydrocarbon mixtures of today's gasoline blends. Our products match petroleum gasoline in functionality and performance. Virent's unique catalytic process uses a variety of biomass-derived feedstocks to generate biogasoline at competitive costs. Our results to date fully justify accelerating commercialization of this technology."
"The technical properties of today's biofuels pose some challenges to widespread adoption," said Dr. Graeme Sweeney, Shell executive vice president of future fuels and C02. "Fuel distribution infrastructure and vehicle engines are being modified to cope but new fuels on the horizon, such as Virent's, with characteristics similar or even superior to gasoline and diesel, are very exciting."
Virent has 68 employees in a state-of-the-art catalytic biorefining development facility in Madison. Virent has exclusively licensed the technology from the Wisconsin Alumni Research Foundation.
