Bifacial PV and PEM-RFC Systems Unite for Sustainable Building Solutions
Researchers at the Khalifa University of Science & Technology in Abu Dhabi, United Arab Emirates, have conducted a study on the integration of bifacial photovoltaic (PV) panels with proton exchange membrane (PEM) reversible fuel cells (RFC) to enhance renewable energy storage across various US climates. The study assesses the impact of environmental variables like sunlight exposure, climate fluctuations, and energy demands on system efficiency and resilience. The research found significant economic benefits through varying bifacial PV gains from 0 to 20% yield with reductions in Levelized Cost of Electricity (LCOE) by 16%, Levelized Cost of Hydrogen (LCOH) by 14%, Levelized Cost of Storage (LCOS) by 13%, and overall system LCOE by 18%.
Key Takeaways:
- The study evaluated the performance of bifacial PV and PEM-RFC systems in five US cities with unique climatic characteristics: Tucson, Los Angeles, Denver, Dallas, and Minneapolis.
- The analysis used metrics such as Levelized Cost of Electricity (LCOE), Levelized Cost of Hydrogen (LCOH), and Levelized Cost of Storage (LCOS) to gauge the economic viability of the systems.
- The research found that varying bifacial PV gains from 0 to 20% yield resulted in significant reductions in LCOE, LCOH, and LCOS, indicating substantial economic benefits.
- The study concluded that bifacial PV and PEM-RFC systems have the potential to boost energy yield and economic efficiency amid dynamic environmental conditions.
- The analytical framework developed in the study provides detailed insights into the economic viability and advantages of these systems in different climatic zones in the United States.
- The research has been peer-reviewed and published in the International Journal of Hydrogen Energy.
