International Journal of Energy Research, Volume 2025, Issue 1, 2025.In the ocean thermal energy conversion (OTEC) system, electrical power is generated by exploiting the temperature difference between cold deep seawater and warm surface water. This study introduces an innovative method that uses a solar collector to increase the temperature of the water entering the evaporator and a wind turbine to increase the useful ...

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 ...

Performance of Heat Pump Air Conditioning with R1234ze (HFO) as a Refrigerant
Journal of Optimization, Volume 2024, Issue 1, 2024.The study shows that refrigerants R1234ze (E) and R1234ze (Z), known for their low global warming potential, are likely to become primary choices in heat pump air conditioning for residential and commercial use. The research evaluates the thermodynamic properties of R1234ze (Z) using experimental, thermodynamic, and numerical analyses.
