“…As the theoretical prediction of microalgal production in PBR is limited, we compare with the available production scenarios from open pond systems. Zemke et al 9 proposed a methodology to predict the production in both PBR and open pond systems 9 . However, microalgal production in PBR with the inclusion of photoinhibition effect is comparable with other reported values from open pond systems.…”

Microalgae have received a great deal of attention among researchers in recent decades in the production of sustainable bioenergy due to the limitations of second-generation biofuels. However, scalability and economics are the two key challenges that need to be overcome for sustainable biofuel production at field level, and mathematical modelling can be utilized as an effective tool to evaluate the influencing factors. This article focuses on the mathematical modelling of microalgal growth and carbon dioxide sequestration potential of a fixed photobioreactor (PBR) at 25 inclination facing south and a two-axis trackable PBR in Odisha, India. The total geographic area of Odisha has been represented in 1195 spatial sites, each site representing around 130 sq. km of the real scale dimensions approximately. The model incorporates site-specific data of solar radiation, climatic conditions and PBR configurations to derive the bioenergy content of microalgal biomass by photon energy balance. The effect of photoinhibition was also studied, and the outputs from the mathematical modelling, such as daily microalgal lipid production and carbon dioxide sequestration potential were plotted for the whole of Odisha using QGIS software. The net microalgal biomass production rate drastically reduced to around 30% and 40% due to the effect of photoinhibition in the case of fixed and trackable PBR systems respectively. The outcome of the present study could influence the policy-makers for selecting suitable sites for the implementation of microalgal-based biofuel production facility.

“…In the case of heat energy balance, irradiance, radiation, evaporation, and conduction were considered along with the heat released by microalgae during its growth. The complete parameters used in the model for theoretical estimation and effect of photoinhibition were listed in Table II. [9], [10] This model aimed to predict the realistic limit of microalgal production rates by accounting the plausible light energy distribution, land use efficiency, photon transmission and utilization efficiency, photosynthetic efficiencies, and microalgal oil content based on the literature data. The mean daily meteorological data, sunlight, ambient temperature and…”

“…Further, similar procedures were utilized to estimate the microalgal production in the five different places of Ethiopia such as Addis Ababa (8.9° N, 38.8° E); Awasa (7.1° N, 38.5° E); Bahir Dar (8.6° N, 39.3° E); Mekele (13.5° N, 39.5° E) and Nazret (8.6° N, 39.3° E) [9]. Zemke et al, (2010) evaluated the maximal theoretical microalgal production for the estimation of triacylglycerides using biochemical and molecular approach of photon requirements of microalgae [10]. Wigmosta et al, (2011) investigated the theoretical predictions of microalgal production by incorporating the effect of water temperature on the production rates [11].…”

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.
