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.
Solar-driven thermochemical conversion of low-carbon fossil fuels integrated with PV-driven electrochemical separation offers viable hydrogen production routes that can combine the strengths of solar PV and solar thermal technologies, and make up for the shortcomings of PV-E discussed above.
Solar PV-E for hydrogen production converts fluctuating PV electricity to stable chemical energy, and provides a stable and time-shifted energy source to support the power grid and address practical energy demands. In addition, the products of water electrolysis (H2, O 2) are produced separately at the two electrodes of the electrolytic cell.
Conventional PEC devices require downstream technologies to capture and store the generated hydrogen gas for its further use as an energy carrier or a fuel. Among various methods, solid-state hydrogen storage appears particularly attractive due to its safety, long-term stability, and application flexibility.
