CSU researchers studying biofuel emissions
FORT COLLINS - Armed with a $325,000 National Science Foundation grant,
two Colorado State University professors will study the emissions
produced from algae as biofuel.
Anthony Marchese and Azer Yalin, associate professors in mechanical
engineering, will focus their research on the potential for unintended
hazardous emissions that could develop if algae biofuel saw large-scale
"One of the reasons we're interested in algae-based biofuels is because
of their potential to reduce greenhouse gas emissions and to reduce our
dependence on imported oil," Marchese said, in a prepared statement.
"What are the consequences if we were to suddenly go from zero to 20
billion gallons of algae-based biofuel per year over the next 20 years?
Are there going to be any consequences that we may not have thought
about? Recent history is littered with examples where we've moved too
quickly with the technology without understanding the risks."
Marchese gave the example of methyl tertiary butyl ether, or MTBE, that
was added to gasoline as an oxygenator. It was pulled from the market
after it was linked to groundwater contamination potentially causing
The duo will work with Jeff Collett in CSU's atmospheric chemistry
department and John Volckens in environmental and radiological health
sciences. Much of the work, which will revolve around how oxides of
nitrogen are produced from biofuel, will be conducted at the CSU Engines
and Energy Conversion Laboratory.
