A Review of Energy Consumption in the Acquisition of Bio-Feedstock for Microalgae Biofuel Production

Microalgae biofuel is expected to be an ideal alternative fossil fuels mitigate the effects of climate change and energy crisis. However, production process microalgae sometimes considered intensive uneconomical, which limits its large-scale production. Several cultivation systems are used acquire feedstock for microalgal biofuels The consumption different different, concentration culture medium (microalgae cells contained in unit volume medium) other properties vary with methods, affects subsequent processes. This review compared systems, including open pond system, four types closed photobioreactor (PBR) hybrid harvesting process. biomass areal every system were also analyzed. results show that flat-panel PBRs column both preferred high productivity.
