University of Maryland researchers patent fermentation of hydrocarbons

In Maryland, researchers at the University of Maryland have been awarded a patent that ferments biomass or gaseous CO₂ and H₂ into hexane and octane much like beer with the use of natural microorganisms. This follows a patent that uses a similar technique to produce ethanol but this time directly into hydrocarbon components. The microorganisms feed on hydrogen and CO₂ and in the long run is expected to be much more energy-efficient and cost-effective than current corn-based ethanol production.
