This study assesses atmospheric carbon dioxide (CO2) capture using algal cultures, a key negative emission technology. Algae offer high efficiency for biomass production, aiding CO2 mitigation efforts.
Area of Science:
- Environmental Science
- Biotechnology
- Climate Change Mitigation
Background:
- Rising atmospheric carbon dioxide (CO2) concentrations drive climate change and global warming.
- Diffuse emission sources necessitate direct air capture technologies, termed negative emission technologies.
- Bioenergy with Carbon Capture and Storage (BECCS) is a promising strategy for CO2 mitigation.
Purpose of the Study:
- To evaluate the potential of algal cultures for atmospheric CO2 capture.
- To explore algae as a sustainable biomass source for negative emission technologies.
Main Methods:
- Assessment of algal cultures for CO2 removal efficiency.
- Analysis of biomass yield and photosynthetic efficiency in algae.
- Evaluation of the economic viability of algal biomass applications.
Main Results:
- Algae demonstrate high photosynthetic efficiencies and biomass yields.
- Algal biomass has diverse applications, enhancing process economic viability.
- Algal cultures show significant potential for atmospheric CO2 capture.
Conclusions:
- Algal cultures are a viable option for negative emission technologies.
- The use of algae in BECCS can contribute to CO2 mitigation.
- Further research into algal cultivation for carbon capture is warranted.
