Approaches to Techno-Economic Assessment of CO2 Capture, Storage, and Utilization Technologies

A comparative analysis of studies devoted to the development of approaches to defining key criteria for techno-economic assessment of the prospects of innovative technologies for the capture, storage, and utilization of carbon dioxide, mainly completed over the past decade, was conducted. It is established that the main components of such an assessment are technology readiness level, life cycle assessment, and the so-called carbon footprint, which, in turn, is related to the magnitude of the global warming potential. It is shown that for CO2 production models key indicators are (a) technical (technology readiness level, operating temperatures, operating pressures, total CO2 conversion, life cycle assessment); (b) economic (capital expenditure CAPEX, operating expenditure OPEX, total production cost, product price, etc.); and (c) environmental (energy 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.
