Here, also the influence of various process configurations is elucidated. The first two rows of the table report the same results of figure and are not analysed further. The raw 'PtX with CO2 from capture' refers to the case in which the CO2 is not available as a waste stream but must be separated from a flow gas stream (post-combustion carbon capture). In this case, the cost of the products increases significantly. The cost increase is in the order of 200% for electricity production and 300% for H2 production. This shows that the source of CO2 is a critical point with the current state of the energy systems, highlighting that the coupling of PtX with energy storage purposes is essential to favour the market entry of these technologies.
