Methodology for conducting a technical and economic assessment of technologies for CO2 capture, storage and utilization

A comparative analysis of studies devoted to the development of approaches to determining key criteria for conducting a feasibility study on the prospects of innovative technologies for carbon dioxide capture, storage and utilization, mainly carried out over the past 10 years, has been carried out. It has been established that the main components of such an assessment are: the level of technology availability, the duration of its life cycle and the so-called carbon footprint, which in turn correlates with the magnitude of the global warming potential. It is shown that for CO2 production models, the key indicators are: a) technical (technology availability, operating temperatures, operating pressures, total CO2 conversion, life cycle assessment); b) economic (CAPEX capital costs, OPEX operating costs, total production cost, product price, etc.); c) environmental (electricity consumption, net CO2 utilization, carbon footprint, water consumption, etc.). The leading countries in the development of these technologies are the USA, Great Britain and Canada.
