It is noted that the use of a CaL-type carbon capture system in natural gas thermoelectric plants (S3) results in higher costs than if the same system were to be coupled to a coal-fired power plant (S2). This is mainly due to the price of natural gas (74.60 USD/MWh), which is about two-fold of that associated with coal . The magnitude of the coal price in the international market also justifies the smoothing of the
