When electrolyzer-based hydrogen production is implemented using a system design that includes PV solar panels and energy storage, the PV solar array is usually placed first. A system of energy storage, like batteries, receives the electricity produced by the solar panels after they have absorbed sunlight.
The efficiency of a solar-to-hydrogen system, known as solar hydrogen production, involves multiple conversion stages: solar energy capture, electrical power generation, and hydrogen production through electrolysis.
Improving hydrogen production using solar energy involves developing efficient solar thermochemical cycles, such as the copper-chlorine cycle, and integrating them better with solar thermal systems. Advancements in photolysis for direct solar-to-hydrogen conversion and improving the efficiency of water electrolysis with solar power are crucial.
This study proposes an innovative energy management strategy that ensures a stable hydrogen production rate, even with fluctuating solar irradiation. By integrating battery-assisted hydrogen production, this approach allows for decentralized, grid-independent renewable energy systems, mitigating instability from PV intermittency.
These results show that the use of energy storage as a bridge between a solar power plant and an AWE is an effective strategy to reduce the unit cost of hydrogen production by decreasing the AWE capacity. The techno-economic analysis for green hydrogen production cost.
