Renewable Energy -Ethanol

Ethanol Energy

Energy is the basic need of human's life and development. With the sustained rapid economic development, non-renewable resources such as oil are limited in earth and gradually running out.
According to the several assessments by International Energy Association (IEA), the massive industrialized exploitation of petroleum will come to an end in about fifty years.

Limited crude oil supplies and refining capacity, and rising concern over environmental degradation provide ethanol with a good market outlook.. Ethanol will be increasingly used for environmental protection, energy conservation and agricultural products transformation.
Future of Ethanol Fuel and Additives

Ethanol is one of the best tools to fight air pollution from vehicles. Ethanol contains 35% oxygen. Adding oxygen to fuel results in more complete fuel combustion, thus reducing harmful tailpipe emissions. Ethanol gasoline and ethanol diesel will be greatly promoted in the future.

The government in the United States has implemented the vigorous development program of ethanol fuel with the target of increasing the ethanol fuel consumption (excluding ethanol diesel) up to 4.4 billion gallon/year (13.6 million t/year) from 1.5 billion gallon/year (4.5 million t/year) by 2011.

The study report provided by the University of Tennessee forecasts the achievement of 60 billion gallons of ethanol and 1.6 billion gallons of biodiesel per year:
• Can be achieved without using CRP lands,
• Will be fostered by research increasing agricultural productivity and commercialization of cellulosics to ethanol,
• Is projected to result in a cumulative increase in net farm income over the 2007-2030 period of $210 billion,
• Is estimated to impact the nation's economy by $350 billion and 2.4 million jobs, with much of these impacts occurring in the nation's rural economies,
• Will provide for displacement of more than 20% of the gasoline by 2030; potentially reducing oil imports by $52 billion, and
• Can result in cumulative displacement of 10.48 billion barrels of oil, and a potential import reduction of $629 billion through 2030.

Future of Ethanol Fuel Cells

Ethanol can be used as the fuel for fuel cells. Ethanol fuel cell is widely used in low temperature fuel cells such as phone cells, notebook computer batteries and other portable power fuel cell in 10~20 years. Ethanol has been identified as a safe, convenient, practical fuel cell. This new type fuel cell will occupy 30~40% market percentage and the capacity will be 5 times as much as now (mainly cellulosic ethanol)

Future of Ethylene-based Ethanol Petro-chemistry

Ethanol will become the basic raw material for ethylene-based petrochemical industry. Ethanol is predicted to replace ethylene in the future.

Future of Cellulosic Ethanol

New technology will break through the concept of grain-ethanol. With the application of modern technology and gene research technology, there has been a breakthrough in promoting ethanol production. The rapid conversion of xylose yeast has been applicable, which has changed the resource-shortage status of grain-based ethanol. Cellulosic ethanol production will proves more economic and industrialized in 10 years. Cellulose is the most abundant renewable energy in the earth. Cellulose as the raw material of ethanol will meet the great demands in ending-oil era and post-oil era.
