Carbon Capture and Utilization by Algae with High Concentration CO2 or Bicarbonate as Carbon Source

Yang, Yi, Tang, Shuo, Chen, J. Paul·2024·Science of The Total Environment

Abstract

Algae plays a key role in carbon capture and utilization (CCU) as it can capture and use the atmospheric CO 2 for conversion of value-added products. Concentrated CO 2 is common in flue gas and provides opportunities for algae cultivation. The drawbacks are mass transfer limitation, poor CO 2 dissolution, and challenges to reach optimal levels for algal growth at given flue gas levels. Bicarbonate is flexible to be used as carbon source and owns the potential to enhance the efficiency of biological carbon fixation by algae. The requirements of algae strains are more stringent. To improve the industrial scale-up of CCU, system optimization is of great importance. More novel algal strains that can grow rapidly under harsh environment and provide valuable bio-products should be developed for large-scale production. Algae-driven CCU is promising for achieving carbon-neutrality.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Bicarbonate application significantly improves carbon fixation efficiency in algae and enhances carbon utilization by increasing production of intracellular total sugars, exopolysaccharides, chlorophyll, and phycocyanin.

    “Their study demonstrated that, in addition to significantly improving carbon fixation efficiency in algae, bicarbonate application can enhance carbon utilization by increasing the production of intracellular total sugars, exopolysaccharides, chlorophyll, and phycocyanin.”
  • Under specific pressure and temperature conditions, Henry's Law governs CO2 solubility in liquid, limiting the CO2 available to algae.

    “Under specific pressure and temperature conditions, Henry's Law governs the solubility of CO 2 in liquid, limiting the CO 2 available to algae [150].”
  • Converting CO2 into a bicarbonate solution used as a carbon source in algal cultivation systems overcomes the limitations of gas-phase CO2 dissolution.

    “Studies have demonstrated that converting CO 2 into a bicarbonate solution, used as a carbon source in algal cultivation systems, overcomes the limitations of gas-phase CO 2 dissolution [150,152-154].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
