Techno-Economic Evaluation of Floating Photovoltaic-Powered Green Hydrogen for FCEVs in Various Koppen Climates

Strategic Insights -

Researchers from the University of Exeter conducted a comprehensive analysis of a 10 MW floating photovoltaic (FPV) system deployed across different Koppen climate zones. The study aimed to evaluate the technical efficiency and economic viability of FPV systems in various climates. The results indicated that temperate and dry zones exhibit significant electricity generation potential from FPV systems, with the lowest payback period of 5.7 years. The system is integrated with hydrogen generation, with the highest amount of hydrogen production being 292,817 kg/year, refueling more than 100 cars per day.

Key Takeaways:

  • The FPV system deployed in different Koppen climate zones generated significant electricity, with temperate and dry zones exhibiting the highest potential.
  • The study evaluated the technical efficiency of the FPV system using PVsyst simulation and HOMER Pro, indicating a payback period of 5.7 years for the lowest-cost zone.
  • The FPV system was integrated with hydrogen generation, producing 292,817 kg/year of hydrogen, equivalent to refueling more than 100 cars per day.
  • The study highlighted the environmental benefits of reducing water loss in the form of evaporation.
  • The LCOH of the system was calculated to be GBP 2.84/kg for 20 years.
  • The integration of FPV with hydropower plants is suggested for enhanced power generation, reaffirming its potential to contribute to a sustainable energy future.

Statistics:

  • 18,829,587 kWh/year of electricity was generated in the dry climate zone.
  • 292,817 kg/year of hydrogen was produced in the dry climate zone.
  • The payback period for the lowest-cost zone was 5.7 years.
  • The LCOH for 20 years was GBP 2.84/kg.
  • More than 100 cars can be refueled per day with the produced hydrogen.
