For the further development of CCS (Carbon Capture and Storage) an integrated approach is needed to optimize the full chain from capture, via transport to application. It is to be expected that in the near future carbon dioxide will be one of the largest commodities. Besides storage as the main option to discard the captured CO2 more sustainable option are emerging where CO2 is used as a feedstock.

A number of options for CO2 utilization are evaluated, and one of the most promising options, biofixation of CO2 by microalgae, is discussed in detail. One of the main aspects of mirco-algae is the scale-ability, both small-scale and relatively large-scale applications can be envisaged. Results for the growth of different microalgae in the presence of CO2 and the extraction of valuable components from the algae biomass are presented.
