Cutting carbon emissions and reduction in global warming, world is relying on the carbon

capture approach. To see the world with Net Zero Emissions by 2050, researchers strongly

believing in the carbon capturing and storage to be combat technique for climate change.

Various studies have been conducted to evaluate the techniques from simple direct absorption

to novel membrane adsorption and biological methods. In achieving the impossible, this

review paper mainly focused on the comparison of two carbon capturing methods: Natural

Mineralization and Artificial Algal System Sequestration. Among the other terrestrial

organisms, algae are found to have forty times higher photosynthesis rate which gives more

weightage to the algae to be the part of bio-circular economy by diversifying the feed stock

and raw material. Overview on the potential of carbon capture and storage technologies, the

review articles further elaborate findings of the comparative study of both approaches and

their benefits in terms of carbon cutting and climate action. Key parameters considered in the

comparison were capturing and storage efficiency of both techniques, capacity and

socioeconomic constraints involved in both approaches. The objective of article also includes

the future roadmap for research and development for such approaches and give the idea on

merger of various subjects to furnish the algae as commercial feedstock to cut carbon
