2 Bioenergy vs Petroleum-based energy * petroleum-based energy - price - demand vs supply - CO emissions * Bioenergy - CO recycle - renewable resources - cheap, economical - technology innovations

3 Bioenergy - Methane gas - bioethanol - biodiesel - biobutanol - biohydrogen - methane from CO - methanol from methane - artificial photosynthesis

4 Bioethanol - cellular metabolism (yeast) glucose pyruvate ethanol TCA cycle CO + H O aerobic condition : CO + H O anaerobic condition : ethanol + CO

5 Bioethanol – raw materials sugar cane starch material - starch glucose ethanol - amylase enzyme cellulosic material - cellulose glucose ethanol - cellulase enzyme

6 Bioethanol – cellulosic material wood cellulose hemicellulose lignin

7 Bioethanol Brazil : sugar cane ethanol USA : corn ethanol * gasohol (gasoline + ethanol) * ethanol from cellulose ethanol from waste paper * Thailand, Philippines : 10% gasohol * Korea : ?

8 Biodiesel (oil) + ethanol FAME + glycerol FAME : fatty acid methyl ester (biodiesel) plant oil - corn - rape seed (canola) - palm - jatropa - waste oil
