Tapping the full potential of clean, renewable energy resources to effectively meet the steadily increasing energy demand is the critical need of the hour and an important proactive step
Dihydrogen (H2), commonly named ''hydrogen'', is increasingly recognised as a clean and reliable energy vector for decarbonisation and defossilisation by various sectors. The global hydrogen
When combined with hydrogen storage systems, fuel cells can provide a clean and reliable source of power. They offer several advantages, such as high efficiency, low emissions, and scalability for various applications.
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.
To partially power this hydrogen production system using solar energy, it is essential to identify hot and cold currents. This allows for the integration of a solar system with a suitable heater if high thermal energy is necessary.
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.
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.
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.
Hydrogen production from the solar thermal collectors were reviewed. Steam reforming, prevalent in the chemical industries, operates effectively with methane and steam. Thermochemical processes efficiently convert biomass into hydrogen for large-scale production.
