This study aimed to collect data for an evaluation of alternative technologies (microalgae cultivations and reforestation) for biofixation of CO2 from the atmosphere near a power plant, named Barbosa Lima Sobrinho, which uses natural gas and diesel as fuels. There is a project to assess the effect of reforestation for CO2 fixation in this facility and, in this study, we evaluated the alternative of cultivating microalgae. An initial review was done in the literature to determine what species of microalgae would be most suitable to use and Chlorella sp was selected. Thereafter cultivation of microalgae media, commonly employed in the market, were evaluated and the culture selected was in open tanks as a reference for the modeling process. Using data from the thermoelectric and the literature it was possible to estimate the amount of CO2 that will be capture from the atmosphere if a microalgae farming will be installed in thermal power plant area. An economic analysis was performed to determine the feasibility of the project. The results indicate that the use of this technology is promising
