During the last ten years the global production of biofuels has increased about five-fold. Biofuels production in 2016 included approximately 23 billion gallons (87 billion liters) of fuel ethanol produced mostly from corn in the US and sugar cane in Brazil, approximately 8 billion gallons (30 billion liters) of biodiesel produced mainly from vegetable oil, animal fat (tallow, lard) or waste frying oil and approximately 1 billion gallons (4 billion liters) of hydrotreated vegetable oil (a drop-in hydrocarbon biofuel also called green diesel and green jet fuel). The year 2016 was an important year because several industrial plants began producing fuel ethanol from cellulosic feedstocks (including switchgrass and corn stover), however less than 1% of the total biofuels were produced from cellulosic feedstocks. This presentation will describe the current status of biofuels, will describe some additional obstacles that will need to be overcome to ensure continued commercial success, and will include some predictions about the future of cellulosic biofuels.
