EIA: More than 1 billion gallons of renewable drop-in diesel/jet produced worldwide in 2014

Green Car Congress

HEFA fuels are hydrocarbons rather than alcohols or esters and are the most common drop-in biofuels; they can be used in diesel engines without the need for blending with petroleum diesel fuel. Currently, HEFA fuels are also approved by ASTM International for use in jet engines at up to a 50% blend rate with petroleum jet fuel.
