Due to its dilute nature, the CO2 gas stream from flue gases is in most cases unfeasible to be utilized directly for the production of fuels and chemicals due to the limitations by the thermodynamic driving force, and it, therefore, has to be captured and purified in an energy-and cost-demanding process . The development of a technology for mitigation of CO2 emissions from flue gas streams by the use of CCU is therefore imperative, and the progress of these technologies to reduce the associated costs remain an essential element in the journey toward carbon neutrality.
