Fuel Generation from CO2

Abstract

Aware of the uncontrolled increase in greenhouse gas emissions, and designated as the main contributor, carbon dioxide (CO2), until now, has been the hottest point in research on gaseous waste management. Thus, the use of CO2 is attracting more and more interest in renewable fuel generation processes. In this sense, this chapter aims to compile a wide range of applications for the use of CO2 as an essential raw material in the conversion of fuels. Beyond briefly discussing the technologies for direct chemical conversion of CO2 for the generation of alternative fuels, our approach focused on examining in more detail the biological use of CO2, through microalgae-based processes. Finally, the chapter presents some recommendations for the future exploration of CO2 generation technologies for fuels.
