Biofuels from Microalgae:
Photobioreactor Exhaust Gases
in Oxycombustion Systems
Ihana Aguiar Severo, Juliano Smanioto Barin, Roger Wagner,
Leila Queiroz Zepka and Eduardo Jacob-Lopes
Abstract The aim of this chapter is to present a comprehensive overview of
integrated bio-oxycombustion systems with photobioreactors. Divided into seven
distinct topics, the chapter discusses issues related to fundamentals of oxycombustion, the operational implications for oxycombustion-enhanced performance,
oxygen produced by photosynthesis, volatile organic compounds as energy source,
photobioreactors design, the process integration in bio-oxycombustion systems, and
the hurdles of bio-oxycombustion technology, summarizing a range of useful
strategies directed to the sustainable development of industrial combustion systems.

1 Introduction
Carbon capture and storage or use (CCS/CCU) is recognized as one of the options
to mitigate the increase of atmospheric carbon dioxide (CO 2 ) concentration
(Koytsoumpa et al. 2017). However, through biological carbon capture and utilization (BCCU) as a concept of bioconversion of greenhouse gases (GHG) into
value-added metabolic products, oxycombustion has gained considerable attention
in recent years (Jajesniak et al. 2014).
Oxycombustion is a promising carbon capture technology due to its ability to
reduce emissions by up to 90%, improving the energy efficiency of industrial
combustion systems. However, the main barrier to be overcome from
