Strategic Insights

— 1 min read

Researchers at the Egypt-Japan University of Science and Technology have made a significant discovery in the field of concentrated solar-operated green hydrogen production. By integrating solar photovoltaic cells with a compound parabolic concentrator, the system is able to drive proton membrane electrolysis, resulting in a promising and cost-effective method for producing green hydrogen. According to the study, the system's performance parameters were evaluated under winter and summer conditions, with the hydrogen production flowrate reaching a peak of 0.0175 kg/h in summer and 0.0144 kg/h in winter.

Key Takeaways:

  • Theoretical work for concentrated solar-operated green hydrogen production system using compound parabolic concentrator (CPC) integrated with solar photovoltaic (PV) cells driving proton membrane electrolysis (PME) was developed, analyzed, and evaluated under winter and summer conditions.
  • Mathematical models for the system components, including the CPC-PV integrated unit and the electrolyzer, were developed and solved using MATLAB.
  • The system's hydrogen production flowrate reaches a peak of 0.0175 kg/h in summer and 0.0144 kg/h in winter.
  • The CPC-PV system power output can reach up to 607 W in summer and 590 W in winter.
  • The PV efficiency in the CPC-PV system increases to about 14.75 % in both seasons.
  • The overall system shows a summer and winter efficiency of nearly 13 % with a slight variation between both seasons.
  • The minimum achieved cost of hydrogen production of the system during summer and winter is $0.17/kg and $0.271/kg, respectively at concentration ratio of 5.
  • The system shows promising performance under operation of different concentration ratios provided by CPC-PV system.
