Product and blend
Neat ethanol is ethanol before blending. Denatured fuel ethanol has an added denaturant that makes it unfit for beverage use. E10 and E85 describe nominal ethanol blend levels; vehicle and seasonal specifications still matter.
Price location
Plant-gate, terminal, rack and retail refer to different points in the supply chain. Basis is the difference between a local cash value and a chosen benchmark.
Compliance language
Carbon intensity expresses lifecycle greenhouse-gas emissions per unit of energy under a defined method. A compliance credit is a regulatory instrument, not a litre of fuel.
