Hydrogen (H2) as a clean and environmentally-friendly carrier can be introduced as the fuel of future to mitigate the air pollution caused by industrial anthropogenic activities. With the aim of fulfilling the need of a green H2 green production, disparate technological processes have been developed in current decades. Purposeful review of these H2 production processes can allow the expert readers as well as non-expert readers to properly perceive the limitations and future perspectives for future research. H2 may be manufactured from renewable or non-renewable energy sources. Despite significant advancements in the techniques of H2 production, the emergence of various operational/technical challenges in obtaining a steady state and stable H2 economy via increasing the process yield and decreasing production costs has motivated the researchers the study more to develop more efficient processes. Therefore, development of a scientific techno-economic analysis for all existed H2 production techniques is of great importance to highlight the future perspective of this important energy source. The main objective of this paper is to comprehensively review the advantages and disadvantages of various H2 production techniques. Moreover, the economic dimensions of each technique along with the role of nanotechnology in the production of H2 are aimed to be reviewed in this paper.
