2 Overview 1 Vision of Hydrogen Economy Construction of Refueling Station Infrastructure of Hydrogen Development of VR Operator Education System of Hydrogen Fueling Station SAFETY FIRST For the purpose of assessing impacts on people inside and outside e a station, it is significant to understand the general hydrogen properties, the function f and use of the facilities, and possible accident scenarios. Operator Education, Training Virtual Reality Accident Scenario

3 Hydrogen Safety Problems 2 Which questions must be answered regarding hydrogen safety? What is the risk, and how to minimize it, in connection to new infrastructure, filling, production, and storage? How to prevent or minimize consequences of any internal explosion when staring to sell H 2 cars? What if there is a significant leak in a car commercial or transport vehicle? How to dimension a container or pipes with flammable H 2 -air? - What if hydrogen leaks inside a congested process facilities? - How to optimize wall strength and vents? - How to design ventilation system in leak-exposed buildings?

4 Hydrogen Fueling Station 3 Fueling Station Type On-Site Type Off-Site Type Steam Reforming Production Naphtha, LPG, LNG Electrolyze Production Water Compressed Hydrogen Delivered Gas Liquid Hydrogen Delivered Liquid, Vaporizer Compressor, Storage, Dispenser Compressed Hydrogen Delivered Reformer Compresso r ESD Breakaway Storage Dispenser Leak Monitor Vent

5 Hydrogen Station Simulator 4

6 Virtual Reality Experience Module 5 Trainee can understand and practice these processes indirectly. The trainee can easily find the necessary information with user-friendly GUI consisting menu, command buttons, selection boxes, icons, and so on.

7 Type of Hydrogen Fueling Station 6

8 Type of Hydrogen Fueling Station 7

9 Fueling Station Facilities & Safety Equipment 8 The virtual reality experience module display hydrogen fueling station facilities (HDS, Reformer, WGS, PSA, Compressor, Storage, Dispenser, Control Office, Fuel Cell Vehicle, etc.) and safety equipment (Emergency Shutdown Device, Vent Stack, Protective Wall, Leakage Detection System, Programmable Logic Controller, etc.).

10 Animation Event of Emergency Safety Device 9

11 Virtual Reality Experience Module 10 Trainee can select main facility(producer, compressor, storage and dispenser) and view them from various angles by rotating scale up and down.

12 Accident Scenario Module 11 A dynamic simulation is conducted by commercialized by commercialized CFD program developed hydrogen accidents model. A movie or animation file offers the simulation results could easily understand hydrogen station accidents.

14 Dynamic simulation result of hydrogen leak in the dispenser (0.1s, 0.8s) Simulation Results 13 Hydrogen Leak in Dispenser Dynamic simulation result of dispenser leak in electrolysis hydrogen station (7.2s, 26.4s, 50.4s)

15 Simulation Results 14 Hydrogen Explosion in Storage Dynamic simulation result of storage explosion in reforming hydrogen station (0.132s, 0.148s, 0.157s)

16 Conclusion 15 This program gives much helpful information for trainee to understand effectively about the hydrogen fueling station, to operate more safely, and to make plans against emergency. The final developed program may offer all the information about hydrogen fueling stations and may be not only the effective operator training program but also the public relations for safer use of hydrogen.
