A pilot, $30$ cm depth, large$-$area, microalgal raceway is used to sequester CO$2$ from a coal fed power station, operating at $10$ MW$,$ with a capacity factor of $58\%.$ Space is limited next to the power plant and only $10$ ha is available for the raceway. Assuming that the microalgae can grow at $0\mathrm{.}5$ g$/$L$-$day over $365$ days per year and utilize the emitted carbon, calculate the total CO$2$ emissions that could be sequestered from the power plant per year and what this is as a fraction of the plant$$s total emissions. Cleary state any assumptions that you make and briefly comment on your answer and potential problems with this CCS method. How can this fraction be increased with the limited footprint available?
