Scientists Determine New Strategies for Next-Generation Biofuel

Conventional insights offered by research on biofuels convey that efficiency of carbon is the most effective strategy for producing better biofuel. According to scientists, the production efficiency is directly proportional to number of carbon from crops which get utilized for making biofuel. But getting more carbon in biofuel may not be the defining point. According to recent study by researchers at the University of Wisconsin–Madison and the Great Lakes Bioenergy Research Center (GLBRC), the quality of the biofuel and energy needed to produce them are equally important factors in deciding better next-generation biofuel strategies.

The work is detailed in a paper published in the journal Joule on September 28, 2018.

CCA Conversion Offers Stiff Competition to BCE in Efficient Fuel Production

The scientists are more focused toward developing new biofuel strategies apart from the carbon efficiency. The researchers also examined two other important factor such as the fuel efficiency when use in vehicle and the energy required to produce in a bio refinery. To this end,the researchers compared two processes for producing biofuels from the corn stover, which is catalytic conversion to alkene (CCA) and biological conversion to ethanol (BCE). In which, alkenes are long carbon chain and comprises of at least one double bond and those produced from CCA are diesel.

Their result evaluates all aspects such as fuel efficiency, carbon efficiency, and requirements of processing energy, in deciding for the most effective strategies for biofuel production across the globe. As per the researchers, the BCE has very high carbon productivity, but the fuel itself has very less energy in its content. Whereas, CCA has less energy carbon which has higher fuel efficiency when it is utilized in a car. As a result the CCA method produces better fuel despite being less efficient in terms of carbon, since it produces more mechanical energy using both electricity and fuel.
