The theoretical efficiency of this solar hydrogen production system is 36.5% (Kaleibari et al., 2019). However, the energy obtained from the full-spectrum utilization of solar energy is predominantly thermal energy, with an electrical energy to thermal energy ratio of less than 1:2.
Based on the energy management strategy of this system proposed above, the system produces hydrogen stablywhen the solar irradiance changes, i.e., the hydrogen production rate remains unchanged, and the constant electrolytic efficiency of 68.5% is obtained.
Another energy management strategy for stand-alone PV hydrogen production systems has been proposed [ 18] with the aim ofreducing the battery size and loss by reducing the energy circulating in the battery, and the strategy has been validated in real operations.
Hydrogen production using solar power is referred to as solar hydrogen. PC water splitting is actively pursued for hydrogen production because it efficiently utilizes solar energy to address environmental and energy challenges. Photocatalysts driven by visible light are primarily used for solar energy conversion.
However, the majority of hydrogen production today relies on fossil fuels (96%), with only a small fraction (4%) being produced through water electrolysis. Even though there have been many studies on climate change mitigation with a focus on Africa, a green hydrogen production from a photovoltaic power station approach has not been reported.
A prevalent method for generating hydrogen using electricity is through PV cells. In this approach, a PV power plant produces the electricity needed for the electrolysis process. The efficiency of hydrogen production via electrolysis can be significantly increased by using high-performing PV power plants.
