Abstract: Sequester means to withdraw. Bio-sequestration implies sequestering via natural ways.
Furthermore, Carbon sequestration, as the name suggests, involves in capturing carbon-dioxide
from the atmosphere. It’s a long-term storage of carbon-di-oxide or other forms of
carbon to either mitigate or defer global warming. The proposal for the Kota Thermal Power
Plant was to sequester the carbon-di-oxide emitted by the plant with the establishment of an
algae cultivation system at the location itself. It is a suggested pilot project with a budgetary
estimate of $ 27,678,800 /= i.e. Rs. 1,383,940,000/= (At the exchange rate of 1$ = Rs. 50/=).
The technology used would be MEA Extraction Plant i.e. Monoethanolamine Extraction Plant,
that would direct carbon-di-oxide from the Thermal Power Plant to the nearby algae ponds,
where it would be sequestered. The analysis would be conducted to determine the cost
effectiveness of the bio-sequestration technology as a means to reduce carbon emissions.
Furthermore, statistical analysis would be used to evaluate the profitability of the technology
in different time frames and at different price levels prevailing in the carbon credit market, at
different rates of discounts.
