Hydrogen could play a significant role in low-carbon future as an energy carrier that can be easily stored and transported across the transport, heat, industry, and electricity sectors. As we know, the Power-to-Gas concept, based on water electrolysis using electricity coming from Renewables is the most GHG-free approach. However, Green hydrogen is now much more expensive than other energy resources. This is why this paper focuses on analyzing the economic value, especially regarding solar power energy. Commercial solar power system and wind power system are investigated in this study. And the levelized cost of hydrogen (LCOH) is used a key indicator to account for the total economic value of combined system. The result represents to set for the affordable price of REC prices.
