Introduction
An option for the drastic mitigation of CO2 emissions, alternative to the Carbon Capture and Storage concept, is to transform it into valuable compounds, like fuel and chemicals, namely as ‘the CO2 capture and utilization (CCU) concept’. The majority of CO2 use in industry is for urea production, which accounts for more than half of the global annual usage [1]. Alternatively, CO2 is utilized also physically in various applications such as refrigerant medium, in fire extinguishers and in the petroleum and NG industry for Enhanced Oil Recovery (EOR) and Enhanced Gas Recovery (EGR), respectively [2] and [3].
