There is increasing pressure to reduce dependence on foreign petroleum sources. As such, the development of routes to produce fungible fuels from renewable and/or domestic feedstocks has been the focus of significant research. Traditional bio-refining processes rely on microbial fermentation of renewable carbon sources such as sugar into higher value products. More recently, work has focused on the use of non-traditional feedstocks in bio-processing such as cellulosic biomass, pyrolysis of waste biomass, or gasification of organic municipal solid waste, to name a few. OPXBIO is developing an engineered microorganism that produces free fatty acids of targeted carbon chain length utilizing hydrogen (H2) and carbon dioxide (CO2) as a feedstock. The free fatty acids are subsequently converted to alkanes and or jet fuel using chemical catalysis. The proposed process will fix CO2 utilizing H2 to generate an infrastructure-compatible, energy-dense fuel. The proposed process is scalable, the initial economics are favorable, and the liquid fuel can be used directly in the existing diesel infrastructure.
