Abstract—There is a huge urge currently for the new, clean
and renewable energy as well as the protection of environmental
resources for the sustainable livelihood of human. In recent
decades, microalgae received lots of attention for its carbon
dioxide capturing potential and as a valuable feedstock for
bioenergy. This study aimed to analyze the effect of
geographical coordinates on carbon dioxide sequestration by
microalgae using mathematical models. Ten sites at three
different latitudes were chosen for the study based on
geographical location of the places in the Equator, Tropic of
Cancer and Tropic of Capricorn. The key model input
parameters such as solar radiation and other climatic conditions
for the identified potential sites were retrieved from NASA, USA
databases and used as basis for estimating annual microalgal
biomass production and carbon sequestration potential. The
variation in microalgal productivities and carbon dioxide
sequestering potential were very minimal at countries present in
the Equator while the Tropic of Capricorn has relatively higher
productivities than the countries present in the Tropic of Cancer.
This study provides a baseline data for theoretical estimates and
effect of photoinhibition on microalgal photobioreactor
production systems in the selected study locations.
Index Terms—Carbon dioxide sequestration, geographical coordinates, mathematical modeling, microalgae, photoinhibition, photosynthesis.
