CSU Researchers test emissions from burning Biofuel Posted by Rumana on Tue March 30 2010 05:08:06 AM

Many in the field of Renewable Energy hope that Algae Biofuel production reduces the amount of green house gases in the Atmosphere and very Eco friendly too.
But the conclusions are vague and the Reseachers at CSU who are mechanical engineering professors,Anthony Marchese and Azer Yalin are on a mission to find out exactly what gases are emitted when algae oil burns.

"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?" Marchese said. "Are there going to be any consequences that we may not have thought about? Recent history is littered with examples of where we've moved too quickly with the technology without understanding the risks."

Marchese and Yalin have received a $325,000 National Science Foundation grant to conduct a study of emissions from algae-based biofuels, during which they'll look at how pollutants are formed when the fuel burns.

At the heart of the CSU study is gaining an understanding of how nitrogen oxides, known as "NOx" emissions, are produced from biofuel.

"There is a lack of understanding of the chemistry behind NOx and soot formation from biodiesel in general," Yalin said. "Algae-based biodiesel is unique and has a different chemical structure than feedstocks like soybeans, so we're building several experiments to focus on the NOx production and soot as well. In diesel engines, NOx and soot are still a major concern."

Marchese said his team already has studied how algae-based biodiesel combusts in engines, and researchers detected lower levels of NOx emissions than from other biofuels.
