Thermodynamic Assessment of Solar‐Powered Hydrogen Production Using Hybrid Power Cycles

International Journal of Energy Research, Volume 2025, Issue 1, 2025.
The rise in global energy demand amid growing concerns over climate change from fossil fuel emissions has made decarbonization a necessity. However, some industries are difficult to decarbonize with conventional renewable energy systems. Green hydrogen offers a clean path to decarbonizing these industries, but more than 80% of global hydrogen is not ...
