1. unw Prof. Dr. Helge Majer Helge Majer Qualitative Evaluation of PV- and Fuel-cell-driven Boats for Tourist Use in Danube Areas Symposium Donauhochschule Fachhochschule Ulm November 28th - 30th, 2005

2. unw Prof. Dr. Helge Majer

3. The Boat - soft version Idea: HP Lahaye

4. unw Prof. Dr. Helge Majer The Boat - hard version capacity 20-25 persons two crew members high-tech design drag-optimization of hull minimum energy consumption FC - PEW PV - crystallin battery system onboard Idea: HP Lahaye

5. unw Prof. Dr. Helge Majer Methodology 1 Qualitative Assessment and Evaluation with mediating a group of experts, responsible, effected persons 2 Selection of Criteria of Sustainability Reduction as to relevance and practicability 3 Definition of Life Cycle Reduction as to relevance and practicability

6. unw Prof. Dr. Helge Majer Methodology 4 Application of Weights 5 Arguments for applying colors to the areas red - no sustainability at all yellow - partly sustainable green - sustainability fulfilled 6 Limitations

7. unw Prof. Dr. Helge Majer Criteria of Sustainability A. Economic sphere 1 Monetary efficiency 2 Total Efficiency B. Environmental sphere3 Environmental damage 4 Resource use C. Social sphere5 Comfort 6 Safety

8. unw Prof. Dr. Helge Majer D. International sphere 7 International conformity 8 Appliance to rules E. Cultural sphere9 Conformity 10 Acceptance

9. unw Prof. Dr. Helge Majer Life Cycle I Research & Development, Design II Production III Transport IV Operation V Area of Operation, Infrastructure VI Maintenance, Repair, Scrapping

10. unw Prof. Dr. Helge Majer The complete evaluation matrix

11. unw Prof. Dr. Helge Majer The final evaluation matrix

13. Conditions for color selected IV/1 economic efficiency depends on conditions additional utility for stakeholders battery charge on shore monopoly situation (right of operation) preferences of communities synergies absence of electricity supply prohibition of combustion engines sponsors, lighthouse function

14. unw Prof. Dr. Helge Majer

15. Conditions for color selected IV/4 PV green field, fuel cell red field, best case 50:50 Hydrogen must be produced with REG energy PV-power station onshore Energy farms Utilization of synergies

16. unw Prof. Dr. Helge Majer

17. Conditions for color selected II/3 differentiation view (comparison with traditional boats) V/3 differentiation view (comparison) green: life time of fuel cell appr. 5 years yellow: 2 years durable material

18. unw Prof. Dr. Helge Majer

19. Holistiv view Light-house function technology transfer fascination of solar and hydrogen technologies (clean, soft, inodorous, costless, natural)
