Algae biofuel
● Algaculture (farming algae) for making vegetable oil, biodiesel, bioethanol, biogasoline, biomethanol, biobutanol and other biofuels
- using land that is not suitable for agriculture
● Estimates suggests that the per unit area yield of oil from algae is between 4’700 to 18’000 m3/km2/year, this is 7 to 30 times greater than the next best crop, Chinese tallow (650 m3/km2/year)*

Ethanol from algae
● The company Algenol claims a process that can produce 8’450 m3 ethanol/km2/year*
- growing corn and fermenting it produces 350 m3 ethanol/km2/year
- sugar cane yields 830 m3 ethanol/km2/year

Major technology aspects
● Growth of algae - closed (photobioreactors) or open bioreactors (open ponds) - nutrients and CO2 supply
● Importance of light - delivery - capture
● Maximizing the triacylglycerides (TAG) content in algae - engineering of lipid production pathways
● Downstream processing - extraction of oil from algae - waste biomass conversion
