Global Biofuels Status Update  

Posted by Big Gav in , ,

Robert Rapier has an article on biofuels drawing on the recent Renewables 2014 Global Status Report (the BP for this year is also out) - Global Biofuels Status Update.

Global biofuel production falls primarily into three categories; ethanol, biodiesel, and hydrotreated vegetable oil (HVO), also known as “green diesel.” Of the 30.8 billion gallons (116.6 liters) of biofuel produced globally in 2013, 23 billion gallons (75%) were ethanol. ...

Biodiesel is the second largest category of global biofuel, accounting for 6.9 billion gallons globally in 2013 — 22.6% of total biofuel production. Biodiesel is derived from reacting fats like vegetable oil with an alcohol like methanol. The products of the reaction are biodiesel and glycerin. The chemical structure of biodiesel is distinctly different from that of petroleum diesel. Petroleum diesel is composed of only hydrogen and carbon (hydrocarbons), but biodiesel also contains oxygen. This gives biodiesel somewhat inferior physical and chemical properties compared with petroleum diesel. ...

Global biofuel production continues to be dominated by ethanol, and the US is the world’s dominant biofuel producer — leading in both ethanol and biodiesel. HVO is the world’s third largest volume biofuel and its production is growing at a faster pace than the more mature ethanol and biodiesel industries.
