The system produces 455.1 kg/h of hydrogen, a high rate. The area and dimensions of the heliostat mirror, the kind of working fluid, and the heliostats' efficiency are among the examined problem parameters of the solar energy system.
Advancements in photolysis for direct solar-to-hydrogen conversion and improving the efficiency of water electrolysis with solar power are crucial. Comprehensive economic and environmental analyses are essential to support the adoption and scalability of these solar-based hydrogen production technologies.
This contribution is projected to rise in the near future with the progress of renewable energy utilization and electrolyzer design. Since solar energy is abundant, sunlight could be deployed effectively in PV modules and PEM “proton exchange membrane” electrolyzers to promote the generation of green hydrogen.
Hydrogen production relies on the presence of electrical power at the input of the electrolyzer, which is contingent upon the availability of solar radiation. To maximize the solar energy supplied to the load, the availability of solar radiation should match the PV generation.
In a study by Y. Chen et al. , a solar-based new energy generation and storage configuration was studied for energy and hydrogen fuel production. For the solar farm, a PTC was used, and the useful heat from the PTC powered the organic Rankine cycle (ORC), generating electricity.
Solar hydrogen production devices have demonstrated promising performance at the lab scale, but there are few large-scale on-sun demonstrations. Here the authors present a thermally integrated kilowatt-scale pilot plant, tested under real-world conditions, for the co-generation of hydrogen and heat.
