Production of Sustainable Aviation Fuel from CO2-fed Algae Farm: A beneficial way of achieving both green-energy production and CO2 reduction simultaneously

It is expected that about 600-GT CO₂ is expected to be emitted by the industrial sector for the next 50 years. In order to achieve the goal to reduce the industrial CO₂ emission by 75%, an innovative carbon capture and utilization technology should be urgently developed and implemented.  From 2050, all the flights taking off from any airport in the Europe should be fueled with jet-oils more than 70% of which should be sustainable aviation fuel (SAF). By the same year, all the petrol-based jet-fuel consumed in the US will be replaced with SAF. Therefore, 190 private companies located in 330 cities, 73% of which are in the EU or the US, are planning to produce SAF. As one of the most important jet-fuel providers in the world, Korea is finding a stable biomass source for producing SAF. Growing algae for oil extraction has attracted interest from engineers, since its lipid content is 40-60%. If CO₂ is supplemented to the algae-growing farm, a higher yield is expected.  Moreover, CO₂ is supplied to the farm as HCO₃^-, the yield can double. In this presentation, an innovative and economical strategy to produce SAF via utilizing CO₂ from industry will be presented. The feasibility of the strategy will evaluated in a holistic way.
