Critical review of strategies for CO2 delivery to large-scale microalgae cultures

doi:10.1016/j.cjche.2018.07.013

Abstract

Abstract: Microalgae have great, yet relatively untapped potential as a highly productive crop for the production of animal and aquaculture feed, biofuels, and nutraceutical products. Compared to conventional terrestrial crops they have a very fast growth rate and can be produced on non-arable land. During microalgae cultivation, carbon dioxide (CO₂) is supplied as the carbon source for photosynthesising microalgae. There are a number of potential CO₂ supplies including air, flue gas and purified CO₂. In addition, several strategies have been applied to the delivery of CO₂ to microalgae production systems, including directly bubbling CO₂-rich gas, microbubbles, porous membrane spargers and non-porous membrane contactors. This article provides a comparative analysis of the different CO₂ supply and delivery strategies and how they relate to each other.
