The University of Central Florida researchers have been conducting a study into the many types of biofuels to see which one produces the least amount of emissions. And the winner is ethanol, according to the results ethanol produces the least amount of soot. Soot exposure is directly linked to respiratory disease, cancer and heart problems.
Ethanol is already in most gas sold in the US, which gives it an advantage over other biofuels since the infrastructure is in place. It’s also compatible in current engines, as well as, cheap to produce.
This study is funded by the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy and will continue through 2021 to collect data and improve combustion models.
