Hydrogen is considered as an ideal fuel for the future. Solar is one of the major sources of renewable energy and it is also a promising sources for renewable hydrogen production.
Presently, renewable energy contributes only about 5% of the commercial hydrogen production primarily via water electrolysis, while other 95% hydrogen is mainly derived from fossil fuels.
Renewable hydrogen production is not popular yet mainly because the quantum efficiency is still low and the cost is still high. |
