Overall, when the size of the photovoltaic system was additionally considered as a decision variable for a given annual hydrogen production required, the overall trends for LCOH, hydrogen generation, and capacity factor are compatible to the results of the previous simulation case studies.
To this end, a comparative technoeconomic analysis of photoelectrochemical and photovoltaic-electrolytic solar hydrogen production systems was performed. The results indicate an estimated levelized cost of hydrogen (LCH) for base-case Type 3 and 4 photoelectrochemical systems of $11.4 kg −1 and $9.2 kg −1, respectively.
4.2.2. Projection of Future Levelized Cost of PV-Powered Hydrogen Production The uncertainty in the technological progress of both PV and electrolyzer hydrogen production is an important factor affecting the future cost of PV hydrogen production, which will, in turn, affect its economic efficiency.
The cost of hydrogen production is determined by reviewing various government reports and research literature and using governing equations for economics. The minimum cost of hydrogen production and the electricity required to produce 1 kg of hydrogen are calculated to predict the LCOH for each scenario in different years.
Then, we constructed a PV hydrogen production techno-economic (PVH2) model. We used the levelized cost of hydrogen production (LCOH) method to estimate the cost of each major equipment item during the project lifetime. We combined the PVH2 and learning curve models to determine the cost trend of integrated PV–hydrogen technology.
Future technological advances in PV–hydrogen production systems, such as perovskite solar cells (PSCs) and noble metal-free cocatalysts for enhanced photocatalytic H2 production [ 3, 4, 5 ], will play an important role in further reducing the levelized cost of PV hydrogen production.
