Engineers at the University of Wisconsin-Madison have developed a two-stage process for converting biomass-derived sugar into 2,5-dimethylfuran (DMF), a liquid transportation fuel with 40% greater energy density than ethanol.Interesting. Let the race for the perfect designer biofuel begin.
In addition to its higher-energy content, DMF also addresses other ethanol shortcomings. DMF is not soluble in water and therefore cannot become contaminated by absorbing water from the atmosphere. DMF is stable in storage and, in the evaporation stage of its production, consumes one-third of the energy required to evaporate a solution of ethanol produced by fermentation for biofuel applications.
Unclear from the article how efficient the energy conversion from sugar to DMF is compared to ethanol, or how the economics of it look.
