I have spent some time researching the potential of Algae for CO2 sequestration. During this research I get the distinct ?impression? that proper light and/or temperature levels are critical for greatest efficiency of algal digestion of CO2.
I live above the 41st parallel in Michigan, which has the greatest concentration of coal-fired power plants between the 41st & 43rd parallels, which averages roughly 64 sunny days per year. If I operated a coal fired power plant and was considering algae cultivation for CO2 sequestration from my exhaust stacks, only 64 sunny days per year would strike me as being a deal-breaker. Generating the required light levels in a low natural sunlight climate is an added expense that detracts from the financial feasibility of such an endeavor.
This seems to leave maintaining optimal thermal levels as the only feasible means of creating the proper environment for efficient algae cultivation conversion of CO2 in stack emissions. Again, if I operated a coal fired power plant and was considering algae cultivation for CO2 sequestration from my stacks, the lower temperatures during winter months would also strike me as being a deal-breaker. That is UNLESS, transferring the heat from my stacks to an algae cultivator would be sufficient to maintain that optimal temperature during winter.
Does anyone know of a source of real data that could be accessed that could support the claim that "without ample light conditions, heat from stack emissions alone during the coal burning process would be sufficient to support the conversion of CO2 through algal cultivation”?
