A Trends Analysis on Safety for CNG/HCNG Complex Fueling Station

In this research, the safety trends and technologies of HCNG, a mixture of hydrogen and natural gas, are analyzed. This is an attracting alternative fuels to meet the strengthened automotive exhaust gas emission standards. HCNG is very important opportunities and challenges in that it is available the existing CNG infrastructures, meets the strengthened emission standards, and the technical, social bridge of the coming era of hydrogen. It is essential for the commercialization of HCNG that hydrogen - compressed natural gas blended fuel for use in preparation of various safety considerations included accidents scenario, safety distance, hydrogen attack, ignition sources and fire detectors are examined. Risk assessments also are suggested as one of permission procedure for HCNG filling station. , HCNG . HCNG CNG , , , . HCNG - , , , , , HCNG HCNG .
