从化石燃料发电厂的烟气中捕获和封存二氧化碳的物理化学过程非常昂贵。二氧化碳利用的生物过程包括植物光合作用和将生物质转化为燃料，不产生净二氧化碳。陆生植物不能直接利用烟气中的二氧化碳。只有沉水水生植物，特别是微藻，才能在实际过程中利用发电厂烟气中的二氧化碳。微藻具有实现高生产率的潜力，可以转化为气体和液体燃料。对这一过程进行了初步成本分析，分析表明，如果能够实现高生产率，总体成本将优于用于烟气CO2捕获和封存的其他物理-化学过程，但将高于利用陆生植物减缓二氧化碳的成本。微藻二氧化碳利用系统最适用于农业不容易利用的土地和水（海水、微咸水）资源。
Physical-chemical processes for the capture and sequestration of CO2 from fossil fuel-fired power plant flue-gases are very expensive. Biological processes for CO2 utilization involve plant photosynthesis and conversion of the biomass to fuels, with no net CO2 production. Terrestrial plants cannot utilize flue gas CO2 directly. Only submerged aquatic plants, particularly microalgae, can utilize CO2 from power plant flue gases in a practical process. Microalgae have the potential for achieving high productivities and can be converted to gaseous and liquid fuels. A-preliminary cost-analysis of such a process is presented that suggests that, if high productivities are achievable, overall costs would compare favorably with alternative physical-chemical processes for flue gas CO2 capture and sequestration, but would be higher than CO2 mitigation with terrestrial plants. Microalgae CO2 utilization systems would be most applicable where land and water (seawater, brackish) resources, not readily utilized by agriculture, are available.
