Abstract (EN):
Carbon dioxide (CO2) has significantly contributed to the increase of the greenhouse effect. CO2 concentrations have increased over the last several decades mainly due to the increase of anthropogenic emissions. Taking into account the relationship between the world energy demand and the respective CO2 emissions, it can be estimated that the atmospheric CO2 concentration can double those of the preindustrial age by the end of 21st century. In this context, an emerging technology is CO2 biosequestration by microalgae. These microorganisms can fix CO2 using solar energy with an efficiency 10 times greater than terrestrial plants. This biological process was tested for CO2 capture from flue gas. The major adverse effects are the high temperature of the gaseous stream and pH decrease of the culture medium due to the presence of NOx and SO2. Thus, this chapter aims to update researchers, governments, and industries from different regions on the latest developments of CO2 biosequestration by algae.
