A photobioreactor (PBR) system is used to sequester CO₂ from a small boiler operating at 20 kWth, fired with natural gas and with a capacity factor of 25%. Assuming that the microalgae can grow at 2 g/L-day over 365 days per year and utilize the emitted carbon, calculate the total reactor volume that is needed to sequester 100% of the CO₂ emissions per year. Briefly comment on your answer and potential problems of this CCS method.
