Recent advances in CO < sub > 2 < /sub > fixation by microalgae and its potential contribution to carbon neutrality

Chemosphere. 2023 Jan 28:137987. doi: 10.1016/j.chemosphere.2023.137987. Online ahead of print.ABSTRACTMany countries and regions have set their schedules to achieve the carbon neutrality between 2030 and 2070. Microalgae are capable of efficiently fixing CO2 and simultaneously producing biomass for multiple applications, which is considered one of the most promising pathways for carbon capture and utilization. This work reviews the current research on microalgae CO2 fixation technologies and the challenges faced by the related industries and government agencies. The technoeconomic analysis indicates that cultivation is the major cost factor. Use of waste resources such as wastewater and flue gas can significantly reduce the costs and carbon footprints. The life cycle assessment has identified fossil-based electricity use as the major contributor to the global warming potential of microalgae-based CO2 fixation approach. Substantial efforts and investments are needed to identify and bridge the gaps among the microalgae strain development, cultivation conditions and systems, and use of renewable resources and energy.PMID:36720412 | DOI:10.1016/j.chemosphere.2023.137987
