• The integration of the Power to Fuel, Ptf, plant increases capacity factor and efficiency of the Coal Fired Power Plant. • The Carbon Capture and Sequestration System, CCS is not economically justified under the current EU ETS CO2 price. • With the EU ETS CO2 price over 25 €/ton, the solution with PtF and CCS became the most favorable as Cost of Electricity, COE. • Electrical energy cost, followed by the oxygen selling cost, affects the most methanol production cost. • In a future scenario, methanol production cost would be very close to the actual market ones. In this paper, an analysis of the integration of a carbon capture unit and a power to fuel system for methanol synthesis with a coal power plant is presented from the energetic, environmental and economic standpoints. The study is carried out in three different sections. In the first part, the impact of the integration of a carbon capture system (CCS) and of a power to fuel plant (PtF) for methanol production is investigated in terms of plant average efficiency, fuel consumption, CO 2 emissions. In the second part, the annual fixed and variable costs of the power plant, and the annual cost of electricity (COE) are assessed for different plant configurations. Additionally, future scenarios are analyzed considering the impact of European policies on the CO 2 emission's cost, defined by the European Emission Trading System (ETS). Finally, an economic feasibility analysis of the power to fuel plant is performed and the methanol production is evaluated. Moreover, a sensitivity analysis is carried out to evaluate the impact of the most affecting parameters (electrical energy cost, the methanol selling price and the capital cost of the electrolyzer) in terms of Internal Rate of Return (IRR).
