It is generally recognized that algae could be an interesting option for reducing CO₂ emissions. Based on light and CO₂, algae can be used for the production various economically interesting products. Current algae cultivation techniques, however, still present a number of limitations. Efficient feeding of CO₂, especially on a large scale, is one of them. At TNO, two novel methods have been developed for the integration of flue-gas from power plants with algae production for the capture and utilization of CO₂. The first method can be described as being amine based whilst the second is carbonate based. Both methods have in common that algae is used as photochemical desorber of CO₂ from absorption liquid. The advantages of these methods is that they are easy to scale-up, would lead to higher CO₂ removal efficiencies compared to current CO₂ feeding systems for algae, and lower operational cost compared to both conventional CO₂ removal using amines and conventional autotrophic algae cultivation. The impact of the new strategies for integrating power plants with algae are described in order to provide more information on their novel aspects and their potential for CO₂ mitigation.
