# 2 <strong>Biodiesel</strong> oxidation producescorrosive peroxidesExample: 10’ diameter steel UST walls are ~ 6mm0.2 % H2O2 corrosion rate on 1030 steel ~ 2mm/yrAre the peroxides produced in biodiesel oxidationcapable of penetrating a steel UST in 3 years?Not impossible if the UST is routinely exposed tocontaminated fuel, water, and acidity
#3 <strong>Biodiesel</strong> has frequently beenout of spec in the pastIn 2007 National Renewable Energy Lab publisheda nationwide survey of B100 fuel quality >50% B100 samples did NOT meet ASTM D6751 Off spec fuel may contain corrosivecontaminants such as peroxides and water
