Cellulosic ethanol: Future Fuel compete with Gas

By 2030 in the U.S. Ethanol will replace gasoline by one-third of annual usage. The Joint study was released on Wednesday by Sandia National Laboratories and General Motors. Its amazing to see that 75 billion gallons of ethanol produced only from Cellulosic ethanol out of 90 billion gallons of it.

Cellulosic ethanol is a biofuel mainly produced from agricultural and forestry wastage like wood, non-edible parts of plants, grasses etc. It is a environment friendly and renewable energy for transportation fuel.

The difference between Cellulosic ethanol and Conventional ethanol :

Conventional ethanol obtained from edible parts of the food grains, which is usually less productive. Where as cellulosic ethanol can be obtained from non edible parts of food grains like cereal straws and corn stover or from dedicated crops.

Dedicated crops includes sugarcane, cotton woods and switch grass. These crops are raw material for biofuel energy. And all these crops are ability to re-grow with short term life cycle. Advantage is it allows to multiple harvesting without re-planting. These food raw materials are cheap and ample.

Cellulosic ethanol emits less carbon so directly reduces green house effect.
