Abstract: The Institute of Gas Technology has completed 2 years of a 5-year experimental program to supply information about prospects for hydrogen delivery in conventional gas distribution systems. Three model distribution systems were constructed and operated using components loaned or donated by manufacturers and gas utility companies. The three models. Residential/Commercial, Industrial, and Safety Test, have been operated in the laboratory under closely controlled conditions to monitor and compare gas flow and energy delivery, general component performance, and leakage for natural gas and hydrogen. Specific components for any evident effects of hydrogen exposure are being examined. It was experimentally observed that energy delivery as hydrogen could be about 80% that of natural gas under the same operating conditions using a distribution model. Volumetric leakage ratios (hydrogen-to-natural gas) of 2.6:1 to 4.6:1 were measured for various different components in the model systems. No conditions were found corresponding to normal operating conditions of gas distribution where hydrogen will ignite spontaneously from a leak.
