  1. Solar Hydrogen Project IPRO 397 – 301 Advisor: Dr. Said Al-Hallaj Sponsors: BP, BP Solar, Proton Energy Systems, ComEd & IL-DCEO

  2. Team Members • Ariel Simons, Ronak Shah, Harsha Pannala, Vesna Dodevski, Umar Rabbani, Nishant Shah, Steven Peters, Ryad Djerrouf, Elvir Kahrimanovic, Leonardo Melo, Lyes Boundaoui, Adekunmi Keleko (Team Leader). • Brian  Kustwin (Consultant).

  3. Overview • Project Objective • Project Schematics • Individual Group Approaches • Q&A.

  4. Objective • The objective of this project is to design, assemble and analyze a stand-alone distributed power generation system that utilizes solar energy through PV panels and hydrogen storage and conversion to power an LED sign.

  5. Schematic

  6. Approach

  7. The DC/DC Converter Teams 1&2 • Converts PV output to a voltage usable by the electrolyzer • Needs protection from dust and heat • Housing should be made of aluminum, Plexiglas, or plastic • Commercial units not acceptable • Too expensive, provided outdoor protection • Too unprofessional, cheap

  8. DC/DC Converter Experimental Setup The DC/DC Converter Teams 1&2

  9. The Transformer Teams 1&2 • Previous IPROs underestimated input voltage to electrolyzer auxiliaries (240 Vac instead of 120 Vac) • Need 120V/240V step-up transformer to fix this problem • Decided on 1kVA rating to be safe • http://phaseconverter.com/sptransformer.html • $150 before shipping

  10. Project Goals Team 3 • Go to site and inspect electrolyzer and storage tank. • Find out how to connect the fuel cell to the four-way valve for the hydrogen flow. • Find equipment and price that can be purchased and used to connect the fuel cell to the four-way valve • Find equipment and price for a back pressure regulator (BPR) and steel tubing to connect the fuel cell intake with the hydrogen tanks

  11. Team 3 Electrolyzer and Storage Tank • The water storage tank and electrolyzer are already installed . • The electrolyzer is currently inactive, the water tank would needs to be periodically refilled when the electrolyzer is active . • The pump needed to bring the water from the tank to the electrolyzer was installed in the storage tank stand.

  12. Team 3 Steel Tubing / Back Pressure Regulator (BPR) • To transfer hydrogen to the fuel cell the four way valve needs to be connected to the fuel cell intake. • Connected to the stainless steel tubing needs to be a BPR. • BPR takes 250psi inlet hydrogen down to approximately 30psi outlet hydrogen. • Stainless steel tubing, at least 0.25in thick, is needed to prevent significant hydrogen diffusion.

  13. Further Actions Team 3 • A BPR needs to be purchased before all of the gas systems can be put up. • The primary problem in searching for a suitable BPR involves finding an inline BPR instead of the more prevalent panel-mounted BPR.

  14. Team 4 Data Acquisition (DAQ) • The data acquisition was done using LabView which is designed to monitor the Solar Hydrogen System. It measured voltage, pressure, temperature, solar insulation and mass flow of the system elements we studied in this project.

  15. Equipment Team 4 • HP6060B Digital Electronic Load • HP6632A System DC Power Supply • Battery Bank • DC / DC Converter.

  16. Data Team 4 • DC Converter Test Data

  17. Data Team 4 • Constant Resistance Mode Data

  18. Data Team 4 • Constant Current Mode Data

  19. Analysis Team 4 • Resistance vs. Current

  20. Analysis Team 4 • Voltage vs. Resistance

  21. Signal Calculation Team 4 • Voltage (Volt): System voltage • Current (Amp): System voltage/ Shunt resistance. • PV Power (Watt): • Pin = Vpr*Area (PV)/ Cal • PV Power Out (Watt): V*Current

  22. Signal Calculation Team 4 • Solar Radiation Power (Watt/m2): Psr = Vpr/Cal • Total Power, Ptotal: Voltage*Current (of Pv1+Pv2) • Efficiency (%) = Ptotal/Pin*100 • Battery Power (Watt): Vbat*Current.

  23. Hydrogen System Team 4 • The power available at given time of year.

  24. Hydrogen System Team 4 • The time needed to fill tanks at time of year.

  25. Calculations Team 4

  26. Calculations Team 4

  27. Upgraded CameraDVMR 80/CDN 12 Team 5 • Hardware Features: • It comes with four high quality digital camera input • All weather Indoor/Outdoor Rated CDD Cameras • Provides Sony True CCD Color Quality • Automatic switch to infrared in Total Darkness up to 30 feet • Has a reusable (record over) 80 gig hard drive

  28. New Upgraded Camera Team 5 • Software Features: • Allows viewing of all cameras live and recorded video via internet • Has user name and password option for security • Has split screen option • Has ability to ZOOM • 120 fps (frame per second) capacity Order in progress

  29. System Installed Team 5 • Ability to run LabView at all times to record and store data • Share folders, directories with existing system. • To be networked wirelessly to the World Wide Web. • Performed complete diagnostics to improve its efficiency and latest drivers installed.

  30. Website Team 5 • Newer accurate documents/pictures uploaded and linked. • New design/layout applied to the website to reflect modern design.

  31. The End Any Questions?
