Algae for CO2 sequestration

Using algae to sequester CO2 from power plants and other CO2 emitting industries

Algae for CO2 sequestration

I have a big doubt whether all the high oil Algae strains consume more CO2 than other algae? Can I relate the Amount of CO2 consumed to the oil content of Algae? :roll:

How much CO2 do the algae remove per acre?

Algae can absorb over 2 million tons of Co2 a year per acre...

Refer this link…..
Algaecake Technologies estimated that one acre of algae farm will consume 17,000 to 18,000 metric tons of carbon dioxide per year.

The ability of photosynthetic organisms to use CO2 for photosynthesis depends in part on the properties of Rubisco. Rubisco has a surprisingly poor affinity for CO2, probably because it evolved in an atmosphere that had very high CO2 levels compared with the present atmosphere. In C3 plants the Km(CO2) of Rubisco ranges between 15 and 25 µM. In cyanobacteria Rubisco has an even lower affinity for CO2, and the Km(CO2) can be greater than 200 µM. In comparison, the concentration of CO2 in water in equilibrium with air is approximately 10 µM. From these numbers it becomes apparent that Rubisco is operating at no more than 30% of its capacity under standard atmospheric conditions. This is one of the reasons that C3 plants contain such large amounts of Rubisco. Exacerbating this situation is the fact that O2 is a competitive substrate with respect to CO2.
