Challenges faced in CO2 Capture using Algae

While algae-based carbon capture offer the potential to provide sustainable solutions for alternative biofuels and CO2 mitigation, important challenges must be overcome to make them cost-effective and economically sustainable.

Unlike terrestrial crops that have been cultivated and harvested for centuries, the infrastructure and knowledge needed to cultivate and harvest algae using industrial processes is in a pre-commercial stage of development. Within the discipline of plant biotechnology, algal research is one of the least explored fields and industrial-scale algae energy systems will benefit greatly from intense R&D efforts.

Though intermittent investments and progress has been made in recent decades, the potential of algae energy systems has yet to be fully realized and recycling carbon through industrial or agricultural algae energy systems that simultaneously produce biofuels is a relatively new concept.

Clearly-defined goals and significant, well-managed and critical investments are needed in the following areas:

    Carbon life-cycle analysis
    CO2 delivery and conditioning
    Integration and systems engineering
    Strain optimization and optimization
    Energy and water use
    Algal areal and volumetric productivity
    Cultivation system design
    Synthetic biology
    Downstream processing
    Value-added co-products development

The challenges of algae-based CO2 capture are explained in the subsequent pages.
