Synergistic Enviro-Economic Evaluation of a Solar-Green Hydrogen Hybrid System (SGHHS) for Continuous Clean Energy Using a Region-Specific Techno-Economic and Environmental Framework
Evaluates the techno-economic and environmental viability of a solar-green hydrogen system, suggesting a pathway for enhanced energy security in Pakistan.
Key Points
The aim is to assess the feasibility of a solar-green hydrogen hybrid system for continuous clean energy supply in Rawalpindi, Pakistan.
Combined a photovoltaic array, PEM electrolyzer, hydrogen storage, and fuel cell.
Utilized high-resolution climatic data for optimization.
Conducted HOMER Pro simulations for system validation.
Capital cost is estimated at USD 19 million.
Achieved a levelized cost of electricity of USD 0.10/kWh.
Avoided approximately 157,542 metric tons of CO2 emissions over 25 years.
Demonstrated effective hydrogen storage during winter deficits.
