Critical Elements for Industrialization
of Microalgae Fuel
Cost
Conversion (Catalyst optimization,
processing development)
Harvesting and
Extracting
Algae Species (Mutation, screening,
selecting, profiling)
Cultivation (Sunlight, CO2,
system design)

There are the Greatest Diversity of
Algal Resources in China Table 1. Comparison of the species number of algae between china and the world .

Resource Requirements for Optimal
Algal Cultivation
Able to cultivate throughout the year
Energy adequacy (large temperature variance in 24h
cycle)
Sufficient sunny days
Few raining days
Rich in water resources (salt water, fresh water, waste
water, sewage, etc)
Close to CO2 sources
5
Large Scale and High Concentration
CO2 Sources Available in China
Power plants, cement and steel
works account for about 92% of
total CO2 emissions
The distribution of CO2 industrial point
sources were concentrated located
in Bohai Sea Bay, Yangzi River Delta,
and Pearl River Delta

Opportunity and Challenge for
Algae Fuel in China
Opportunity Insufficient nature oil resource
Rising oil price
Government support
Low labor cost
High concerns about climate change (CO2 emission)
Adequate CO2 source provides economic credits and necessary nutrition
Growing interests in green renewable energy
Increasing reluctance to use food products for oil
Challenge
Cost, Cost, Cost
