The combined cycle (NGCC) combines the gas turbine and the steam turbine to generate electricity together, has the characteristics of high efficiency, low cost, less pollution and the like, and is valued and widely applied in various countries of the world. At present, the generated energy of the gas-steam combined cycle power plant accounts for more than 20% of the global generated energy, the net power generation efficiency of the NGCC power plant can reach 55% -60%, and the CO2 generated by the unit generated energy is only half of that of the coal-fired power plant, but the CO2 emission of the unit generated energy is still at a higher level.

Development and utilization of microalgae show more and more excellent potential in terms of relieving energy crisis, reducing greenhouse gas emission and the like, and have attracted more and more attention in recent years.
