Abstract
Ethanol production from sweet sorghum in China was investigated for three cases: 1. Conventional fermentation, 2. Fast fermentation, and 3. Fast fermentation with hydrothermal hydrolysis of horocellulose. Sweet sorghum production in the present corn field in Jilin province will produce 7.1 times as much energy as gasoline used in Shanghai. Fast fermentation is effective for reducing cost of ethanol production. Hydrothermal hydrolysis further reduces the cost by increasing the amount of ethanol production.
