Sorghum is a good fit for a many different types of ethanol production including traditional starch-based, sugar-based and cellulosic ethanol production.
Grain sorghum is an excellent crop for ethanol production because it produces the same amount of ethanol per bushel as comparable feed grains while utilizing one-third less water.
Sweet sorghum, which is also a water-sipper, grows very tall and the stalks contain a high volume of potent sugars. Ethanol can be distilled from those sugars. Research is ongoing into infrastructure development needs to make sweet sorghum ethanol a mainstream reality.
In cellulosic ethanol production processes, the whole plants are used to make ethanol. Forage sorghum is an excellent candidate for cellulosic ethanol production, again, because of its high biomass nature (growing 8 to 15 feet tall) and its low water-use qualities.
