Abstract [en]

This pre-feasibility study was taken out by the co-operation with Zhejiang University, the CEU lab in Zhejiang University is taking researches of the algae based carbon dioxide capture technology, this report mainly aims to evaluate the GHG mitigation effect of this technology and give suggestions.

 

This study was carried out at Zhejiang University based on the Zhoushan islands waste incineration power plant project, the report presents the initial feasibility study for the algae based carbon capture and utilization technology focus on the carbon footprint and value summary . First the algae based CCU technology was introduced, then by using the life cycle assessment methodology and based on the description of the whole algae based carbon capture utilization process, each process unit was defined, concerning mass balance analysis was made for each unit, according to the mass balance analysis, carbon flow data was obtained for the whole process. In the discussion part, the carbon dioxide capture and avoid amount was analyzed, also the economic value summary for the material input and output was discussed. Concerning general suggestions for the further development and research about the project were given in five sectors: biotechnology, cultivation and harvesting, biomass utilization, substance and energy input, human resource.

 

The final conclusion is that the algae based carbon capture and utilization technology is not a carbon negative process, but could produce renewable fuels to avoid certain fossil fuels consumption. Lots of technical limitations exist in the study, it needs more work to applied this technology into reality for China. And the profit analysis based on the value summary for the project is optimistic without the consideration of the initial cost. The algae base CCU technology may become a useful alternative for the carbon abatement in China but not the best choice.
