Abstract

<p>HyGeiaA, a small on-site hydrogen production device, produces hydrogen from city gas and emits flue gas containing CO2 as a byproduct. If the flue gas that is normally exhausted into the air can be used for the growth of microalgae, the cultivation of microalgae may become an effective means of CCU. We developed a glass tube photobioreactor (PBR) installed outdoors that can supplied flue gas and evaluated the performance. As a result, two types of microalgae could be cultured. It was also found that CO2 usage efficiency could be improved by modifying the gas supply section. In the future, we plan to measure the amount of CO2 absorption and fixation rate in detail, and design an expanded model for industrialization.</p>
