This work aims at providing a deeper insight into large scale hydrogen production facilities through Steam Methane Reforming and CO2 capture and storage, considered as a promising option for the decarbonization scenario that has to be reached by the end of 2050. First of all, a technological overview was carried out in order to explore all the feasible options that are present in this moment at different scales, both in terms of size of the plants and development stage. Relevant parameters were extracted from literature, leading to the confidence that Chemical Looping Combustion (CLC) driven plants could become a worhy substitute of tradtional Steam Methane Reforming ones.
