In order to make a fair comparison, an adjusted CAPEX is made including the same level of compression (the base case compresses H 2 /CO 2 from 51.2 bar). As seen from the results, there is a wide spread in the estimated CAPEX. The results of the present study are in close agreement with the results of Campos et al. The results of Nyari et al. are also comparable to the estimates of the present study, considering that hydrogen compression is from 50 bar and CO 2 compression is from 2 bar. Thus, it would be expected to fall within the two cost curves, as is also observed. The work of Perez-Fortes et al. is higher than the comparable cost curve, but this may partially be explained by hydrogen compression being from 25 bar instead of 30 bar. On the other hand, the CAPEX from Atsbha et al. and Mucci et al. seems to be under-estimated, also to some extent the work of Cordero-Lanzac et al. In general the CAPEX modelling provided in the present study seems to be of sufficient quality for techno-economic analysis of green methanol production.
