2007 ICHS Ⅰ. The status of construction □ KIER H 2 station (Compressed Hydrogen Delivery) (Compressed Hydrogen Delivery) □ Yonsei University H 2 station (Naptha Reforming) (Naptha Reforming) hydrogenStation size type supply FCV Nm 3 /hr→200 Nm 3 /hr or over ON-SITE Use of Electrolysis type Pipeline hydrogen application motorcar 3,200 /bus200 1,500,000 3,000,000 9,000, ,000

2007 ICHS Ⅰ. A policy of hydrogen stations in Korea □ Concentrated on fuelcell technology development and supply 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 H 2 stations  The absence of standards for hydrogen facilities

2007 ICHS Ⅰ. CNG station accident CNG Station accident   Date :   Loss of property   These accidents took place just after filling the cylinder and cylinder were ruptured.

2007 ICHS Ⅰ. LPG station accident LPG Station explosion accident   Date :   Casualties : death 1 injured 83   Breakaway from the tank lorry during gas filling

2007 ICHS 『 Hydrogen·Fuelcell safety 』 Research  Hydrogen fueling station standards  FCV fueling supply system standards  Fuelcell standards for manufacture and installation Standards Development Legislation for Hydrogen safety code ~ ~ Ⅰ. Hydrogen safety standards in Korea

Ⅱ. Simulator Development

2007 ICHS Ⅱ. Background □ A part of □ A part of 『 Hydrogen·Fuelcell safety 』 Research □ The 1 st simulator development finished □ The 2 nd step will be started from to □ The 3 rd step will be started from to □ It will be accomplished as results of this project and will be open to public and will be open to public

2007 ICHS Ⅱ. Objectives □ Virtual reality of 4 type H 2 stations constructed in Korea □ User navigate freely through the H 2 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 H 2 stations Reduce a feeling of insecurity for H 2 Application for training and publicity work Reduce a feeling of insecurity for H 2 Application for training and publicity work

2007 ICHS Ⅱ. Overview H 2 energy information Virtual Reality Experience H 2 Station information Accident simulation

2007 ICHS Ⅱ. Virtual Reality Modules First Screen Virtual Reality Execution Screen and Menu Explanation □ Major Equipments in H 2 station Detailed 3D modeling for Station Equipments like H 2 production equipment, compressor, H 2 storage, dispenser

2007 ICHS Ⅱ. Natural Gas Reforming Type   Process Flow viewing from H2 production process to fueling   Move to select process by clicking   Detailed explanation about selected equipments and process   select the equipment and freely rotate, magnify, reduce event

2007 ICHS Ⅱ. LPG Reforming Type A LPG reforming type station view and dispenser A LPG Tank lorry fuel transmission facility   Construction in SK Research Center

2007 ICHS Ⅱ. Naptha Reforming Type   H 2 producing type by reforming conveyed liquid Naptha   Expected to be completed by next week   The only H 2 station in Seoul H 2 station

2007 ICHS Ⅱ. Compressed H 2 delivery type   conveyed H 2 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 H 2 station in Korea   Now operating from 2006

2007 ICHS Ⅱ. Object View   Control Rendering mode about major equipments Basic rendering transparency wire frame mode   Wire-frame mode that user can easily understand composition of equipments by expressing the frame   Transparency mode that view the inside by expressing equipments transparently

2007 ICHS □ 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 Ⅱ. Accident Scenario □ Example Scenario H 2 release during fueling by the dispenser damage (in case the wind doesn’t blow) After 0.1 sec After 0.5 sec After 0.4 sec

2007 ICHS 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 H 2 station

2007 ICHS □ Application Program The Use of EON reality company EON Studio(version 5.5) □ Use the EON Studio on the web application Ⅱ. Program Configuration and management manager System operator server user internet client

Ⅲ. Conclusions
