Among the various carbon dioxide (CO2) capture and utilization (CCU) systems, photoautotrophic mass cultivation of microalgae is the most promising strategy for reducing CO2 from an industrial flue gas with the production of high value compounds. Herein, we propose a cost and energy efficient CCU process using the green microalga, Haematococcus pluvialis. In order to establish economic H. pluvialis mass culture system, the industrial flue gases containing 3–5% CO2 from the combustion of Liquefied Natural Gas. The present system used natural solar radiation and hot water without consuming any electric power to improve the economics of CO2 capture from the flue gas using microalgae. In addition, we developed a low-cost thin-film photobioreactor system with a vertical bubble column. Also, we will expand the culture capacity based on closed PBR system to a 10 ton securing up to 50 tons of Certified Emission Reductions a year, producing 6,000 kg of an astaxanthin yearly. |
