Renewable Diesel Production and
Demand Growing Worldwide, Report Finds
Renewable diesel growth
A new type of renewable, non-petroleum-based diesel fuel is on the rise worldwide, according to the U.S. Energy Information Administration
, with demand driven by mandates in multiple countries. Unlike other biofuels, renewable HEFA biofuels — the acronym stands for hydroprocessed esters and fatty acids, and the fuels are known as "renewable diesel" in the U.S. — are nearly indistinguishable from their petroleum counterparts, meaning they can serve as "drop-in" fuels, readily substituting for traditional diesel. For example, they can be used in diesel engines without the need for blending with petroleum diesel fuel. Worldwide, more than a billion gallons of HEFA fuels were produced in 2014. Ten plants worldwide now produce renewable diesel, and five additional projects are in development. Alaska Airlines, KLM, and United Airlines have demonstrated the use of HEFA biojet fuel on commercial flights since 2011.
