O-21　水素製造装置排ガスを利用したガラス管型フォトバイオリアクターでの微細藻類培養評価

抄録

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.
