As the demand for the reduction of global emissions of carbon dioxide (CO2) increases, the need for anthropogenic CO2 emission reductions becomes urgent. One promising technology to this end, is carbon capture and storage (CCS). This paper aims to provide the current state-of-the-art of CO2 capure, transport, and storage and focuses on mineral carbonation, a novel method for safe and permanent CO2 sequestration which is based on the reaction of CO2 with calcium or magnesium oxides or hydroxides to form stable carbonate materials. Current commercial scale projects of CCS around Europe are outlined, demonstrating that only three of them are in operation, and twenty-one of them are in pilot phase, including the only one case of mineral carbonation in Europe the case of CarbFix in Iceland. This paper considers the necessity of CO2 sequestration in Greece as emissions of about 64.6 million tons of CO2 annually, originate from the lignite fired power plants. A real case study concerning the mineral storage of CO2 in Greece has been conducted, demonstrating the applicability of several geological forms around Greece for mineral carbonation. The study indicates that Mount Pindos ophiolite and Vourinos ophiolite complex could be a promising means of CO2 sequestration with mineral carbonation. Further studies are needed in order to confirm this aspect.

Based on the operating data of a 40 tCO2/day (2 megawatt (MW)) class carbon capture and utilization (CCU) pilot plant, the scaled-up 400 tCO2/day (20 MW) class CCU plant at 500 MW power plant was economically analyzed by applying the levelized cost of energy analysis (LCOE) and CO2 avoided cost. This study shows that the LCOE and CO2 avoided cost for 400 tCO2/day class CCU plant of mineral carbonation technology were 26 USD/MWh and 64 USD/tCO2, representing low LCOE and CO2 avoided cost, compared to other carbon capture and storage CCS and CCU plants. Based on the results of this study, the LCOE and CO2 avoided cost may become lower by the economy of scale, even if the CO2 treatment capacity of the CCU plant could be extended as much as for similar businesses. Therefore, the CCU technology by mineral carbonation has an economic advantage in energy penalty, power plant construction, and operating cost over other CCS and CCU with other technology.

We incorporate the carbonation of ultramafic ore followed by froth-flotation to enhance nickel recovery in the beneficiation stage, instead of the traditional froth-flotation step for nickel processing.

While the demand in reduction of CO2 increases, the need for CO2 sequestration processes is very high. One promising technology is the Carbon Capture and Storage (CCS). In this paper we refer to several papers which study the three main steps in CCS chain. CO2 capture technologies, CO2 transportation to the storage sites and the very critical step the CO2 storage. Recently a novel method (mineral carbonation) for CO2 sequestration has been proposed which is based in the reaction of CO2 with calcium or magnesium oxides or hydroxides to form stable carbonate materials. Greece is a country that emits CO2 mainly from the lignite fired power plant in Western Greece. After the study of the bibliographic references about the use of mineral carbonation process while injecting CO2 in the appropriate geological forms we concluded that there are also these forms in our country and mainly in the area near to the power plant such as in sites Vourinos and Pindos. In these sites exist minerals rich in oxides and hydroxides of Ca, Mg and Fe representing the perfect materials for mineral carbonation.
