  • 1. Sustentabilidade / Renováveis e Pilhas de Combustível João Toste de Azevedo Luis Manuel Alves ECONOMIA DO HIDROGÉNIO, UM DESAFIO PARA PORTUGAL Iniciativas para uma Plataforma Tecnológica Vimeiro, 17 de Novembro de 2008
  • 2. CONTENTS
    • Utsira, Norway
    • Attica, Greece
    • Mljet, Croatia
    • Porto Santo, Portugal
  • 3. Utsira, Norway Utsira – wind hydrogen energy system Norsk Hydro
  • 4. Utsira – wind-hydrogen Stand Alone Power System (SAPS)
  • 5. Utsira – wind-hydrogen Stand Alone Power System (SAPS) SAPS Customers
  • 6. Wind-Hydrogen SAPS
  • 7. Wind-Hydrogen SAPS
  • 8. Hydrogen ”Battery” Renewable power source Consumer Power conditioning/ controller DC or AC AC Electrolyser Hydrogen Fuel cell / H 2 -engine H 2 -refuelling station DC DC Heat
  • 9. Utsira Wind-Hydrogen SAPS Haugaland Kraft Norsk Hydro Electrolyser Enercon Haugaland Kraft
  • 10. Utsira – wind-hydrogen Stand Alone energy system
  • 11. Load profile - customers Peak load: ~ 50 kW Energy consume: ~ 190 MWh/year
  • 12. Hourly rate of load
  • 13. Component characteristics
    • Electrolyser: 50 kW peak (4.8 kWh / Nm 3 assumed) (50-100% operation possible only)
    • HEGS: 60 kW peak (0-100% operation possible)
    • Storage unit: Compressed gas – 200 bar
    • Compressor: Not included
    • Battery: Not included
  • 14. Energy characteristics
    • E WECS = 2805 MWh / yr
    • E el.load (10 houses) = 196 MWh / yr = 19 600 kWh / yr / house
    • E deficiency = E HEGS = 15 MWh / yr
    • E exported = 2544 MWh / yr
    • E to_load & H2-system = 261 MWh / yr
    • E toH2-system = E ELY = 65 MWh / yr
    • Energy efficiency for H 2 -system = 23%
  • 15. Power balance (wind – el. load)
  • 16. State of charge – storage unit Critical period: Storage may be reduced by use of battery
  • 17. Electrolyser and genset
  • 18. Electrolyser and genset
    • Genset:
      • Starts & stops: ~ 60 yr -1
      • Operation hrs: 977 h / yr
    • Electrolyser:
      • Starts & stops: ~ 50 yr -1
      • Operation hrs: 2106 h / yr
  • 19. Storage size
    • 13 m 3 @ 200 bar = 2300 Nm 3
    • This may be reduced by the introduction of a battery
    • Just below 10 m 3 should be possible
  • 20. Attica, Greece RES & Hydrogen Technologies Integration Section RES Directorate CRES
  • 21. Wind hydrogen test site (RES2H2) General View of wind-hydrogen installation 100 Nm 3 in cylinders Filling station Single stage 10 - 220 bar Hydrogen compressor LaNi 5 type 40 Nm 3 in MH tanks Metal hydride tanks 25 kW, 5 Nm 3 /h H 2 20 bar 99.98 %v. purity Alkaline Electrolyser 500 kW Wind Turbine October 2005 Start-up Key data Key Components
  • 22. Wind hydrogen test site (RES2H2)
  • 23.
      • RES & H2 Technologies Integration Laboratory of CRES
      • Objective: The integration of
        • hydrogen production technologies (alkaline and PEM electrolysis – biotehanol reforming),
        • hydrogen storage technologies (compressed gaseous storage and in metal hydrides)
        • hydrogen re-electrification technologies (PEM fuel cells and Alkaline Fuel Cells) in an existing PV-based hybrid system
      • Total Budget: 440.000 Euro
