Biofuels can be obtained from a variety of sources, and microalgaes are of particular interest as one of the most promising sources of biomass for biofuels. In this review, the potential and problem of microalgae bio-energy are analyzed, which indicates that the mode of mass cultivation of microalgae, including improving the growth of microalgae, reducing the energy consumption and enhancing the reliability of mass cultivation of microalgae, is still the main task. Here we introduced the strategy to integrate microalgae bio-energy technology with greenhouse gas reduction in SINOPEC. Besides, the key technologies employed in microalgae bio-energy and the on-going projects of utilizing greenhouse gases to develop microalgae bio-energy in Sinopec Shijiazhuang Refining and Chemical Company, including isolation and characterization of microalgae species, photobioreactors and application of microalgae biomass, are described.
