An extensive amount of studies [17–23] that include either or both technical and economic analyses related to the pre-combustion carbon capture from natural gas are found in the literature, and the most relevant results are briefly summarized. Kanniche et al. [17]
conducted a techno-economic study for different CCS technologies that are applied to pulverized coal combustion,integrated gasification combined cycle, and natural gas combined cycle (NGCC). Kanniche et al. stated that pre-combustion capture by the reforming of natural gas is fairly expensive compared to other CCS methods and it should be used rather in the production of hydrogen than in energy production. Lozza and Chiesa [22,23] conducted an economic analysis of pre-combustion capture technology where partial oxidation (PO) is combined with a NGCC and these costs compared to those of post-combustion carbon capture from NGCC. According to the results, adding the PO process to NGCC increased the relative investment cost ($/kW) by 40–59%,increased the cost of electricity by 36–43%, and resulted in a cost of avoided CO2 as 39–46$/tCO2 . with 90% CO2 capture. Manzoliniet al. [24] studied the cost of pre-combustion CO2 capture based on pressure swing adsorption (PSA) in a natural gas combined cycle. According to the results, the presented pre-combustion process based on PSA increased the specific electricity production
costs by 33–36% compared to NGCC without CO2 capture. With a conventional pre-combustion capture based on methyldiethanolamine (MDEA) the increase was stated to be 38%.
