4. Ⅰ. The Present Status of Hydrogen Stations in Korea

5. Ⅰ. Trend in research • □ First policy measures toward hydrogen in 1992 • 16 research fields • Support 7million dollars from 1992 to 2002 • Hydrogen research started in the latter of the 80’s • Limited to a basic research like hydrogen manufacture ·storage·utilization • □ First Hydrogen fueling stations constructed in 2003 • □ Started on full-scale hydrogen safety research in 2006

6. □ Hydrogen stations(present 5) • construction • (under construction inclusive) • planned(until 2008) • - 2006 : The Metropolitan Area • 2007 : Wind power plant complex • with Electrolysis type • 2008 : Southern area Truck-in type Naptha Reforming Seoul Natural Gas Reforming Compressed Gas Incheon Yongin LPG Reforming Daejeon Natural Gas Reforming Ulsan Yosu Cheju Ⅰ. The status of construction

7. 2005 2015 2020 2030 2040 2010 hydrogen Station 30Nm3/hr→200 Nm3/hr or over size ON-SITE Use of Electrolysis type Pipeline hydrogen application type 10 50 1700 3400 10,000 supply motorcar 3,200 /bus200 1,500,000 FCV 9,000,000 3,000,000 Ⅰ. The status of construction □ KIER H2 station (Compressed Hydrogen Delivery) □ Yonsei University H2 station (Naptha Reforming)

8. Ⅰ. A policy of hydrogen stations in Korea □ Concentrated on fuelcell technology development and supply □ Should accomplish hydrogen safety research □ Should prepare hydrogen standards and risk assessment guidelines for installing hydrogen facilities □ Barriers • The Public recognize that hydrogen is dangerous materials • NGO oppose to construct H2 stations • The absence of standards for hydrogen facilities

9. CNG Station accident • Date : 2005. 1. 27 2005. 8.19 • Loss of property • These accidents took place just after filling the cylinder and cylinder were ruptured. Ⅰ. CNG station accident

10. LPG Station explosion accident • Date : 1998. 9. 11 • Casualties : death 1 injured 83 • Breakaway from the tank lorry during gas filling Ⅰ. LPG station accident

11. 『Hydrogen·Fuelcell safety』Research Standards Development Legislation for Hydrogen safety code 2006.8~2008.7 • Fuelcell standards for manufacture and installation • Hydrogen fueling station standards • FCV fueling supply system standards 2008.8~2009.7 Ⅰ. Hydrogen safety standards in Korea

12. Ⅱ. Simulator Development

13. Ⅱ. Background □ A part of 『Hydrogen·Fuelcell safety』Research □ The 1st simulator development finished 2007.6 □ The 2nd step will be started from 2007.10 to 2008. 5 □ The 3rd step will be started from 2008.10 to 2009. 5 □ It will be accomplished as results of this project and will be open to public

14. Reduce a feeling of insecurity for H2 Application for training and publicity work Ⅱ. Objectives □ Virtual reality of 4 type H2 stations constructed in Korea □User navigate freely through the H2 stations and experience station operation □ Detailed 3D Modeling for major equipments in the station □ Freely Select the equipments and magnifying·rotating· reducing in 3-D □ Accident Prediction by accidents scenario modeling in H2 stations

15. H2energy information H2 Station information Virtual Reality Experience Accident simulation Ⅱ. Overview

16. □ Major Equipments in H2 station Detailed 3D modeling for Station Equipments like H2 production equipment, compressor, H2 storage, dispenser Ⅱ. Virtual Reality Modules First Screen Virtual Reality Execution Screen and Menu Explanation

17. event Ⅱ. Natural Gas Reforming Type • Detailed explanation about selected equipments and process • select the equipment and freely rotate, magnify, reduce • Process Flow viewing from H2 production process to fueling • Move to select process by clicking

18. A LPG reforming type station view and dispenser A LPG Tank lorry fuel transmission facility Ⅱ. LPG Reforming Type • Construction in SK Research Center

19. Ⅱ. Naptha Reforming Type H2 station • H2 producing type by reforming conveyed liquid Naptha • Expected to be completed by next week • The only H2 station in Seoul

20. Ⅱ. Compressed H2 delivery type • conveyed H2 to the station by tube trailer is stored at compressed cylinder of 492kg/㎠ • Fueled to FCV as 350kg/㎠ pressure • Consisted of tube trailer, compressor, dispenser • User can navigate in the station and rotate by selecting equipment • The first H2 station in Korea • Now operating from 2006

21. Basic rendering transparency wire frame mode Ⅱ. Object View • Control Rendering mode about major equipments • Transparency mode that view the inside by expressing equipments transparently • Wire-frame mode that user can easily understand composition of equipments by expressing the frame

22. After 0.5 sec After 0.1 sec After 0.4 sec Ⅱ. Accident Scenario □ Choose the possible 20 accidents scenarios in the station □ Simulation accident scenario by applying ANSYS company’s CFX Program □ The CFD results applied Visual Reality technology □ Example Scenario H2 release during fueling by the dispenser damage (in case the wind doesn’t blow)

23. Ⅱ. Supplementation □ Limits in the accident simulation by applying CFX □ Execute the Dynamic Simulation by using FLACS □ FLACS program enable to simulate explosion and fire in the H2 station

24. System operator manager internet server client user Ⅱ. Program Configuration and management □ Application Program The Use of EON reality company EON Studio(version 5.5) □ Use the EON Studio on the web application

25. Ⅲ. Conclusions

26. Ⅲ. Conclusions □ User can experience the operation of a H2 stations □ Safety training and publicity about H2 station to public □ Reduce the feel of insecurity of H2 safety □ Learn the accident’s type and emergency response plans from a scenario simulation □ Application to prepare standards of the H2 station

27. Ⅳ. Future Plans

28. Ⅳ. Future Plans • □ Construct virtual reality modules of H2 stationsabroad • The type that does not constructed in Korea • □ Development of H2 safety training content modules • Materials related to H2 energy • □ The modules of standards and regulations • related to H2 safety • Materials from all countries of the world
