19. Geothermal Energy Geothermal Energy provides approximately 0.4% of the world global power generation, with a stable long term growth rate of 5%.
32. Why is the field of algae energy interesting? Micro-algae are the fastest growing photosynthesizing organisms. They can complete an entire growing cycle every few days. Under optimum growing conditions micro-algae are reported to produce up to 15,000 gallons of oil/acre/year.
33. Why is the field of algae energy interesting? Grown under conditions which are unsuitable for conventional crop production.
34. Why is the field of algae energy interesting? Capable of fixing CO2 in the atmosphere, thus facilitating the reduction of increasing atmospheric CO2 levels, which are now considered a global problem. Algae biofuel is non-toxic, contains no sulfur, and is highly biodegradable.
35. Energy products from algae Biodiesel Ethanol Hydrogen Methane Biomass – where algae biomass is directly used for combustion Other hydrocarbon fuel variants, such as JP-8 fuel, gasoline, biobutanol etc.
65. Conclusion “ Algae energy has excellent potential as a source of alternative energy but there are significant engineering challenges to be overcome”
