The Journey of Natural Gas

Value chain – The role of FGSZ

FGSZ transports gas from extraction sites, import entry points, and underground natral gas storages upon removal to distribution system exit points, directly connected industrial consumers, underground gas storages when storing, and to border exit points. Only gas of the quality defined in the regulation may be fed into the transportation systems. The natural gas transported in the pipelines is not toxic, however, if it gets out of the pipe, the air-natural gas mixture between explosive limits is explosive. This means that in case natural gas concentration of the air is between 5-15%, an explosive gas mixture develops. In order to avoid any possible gas exlposions, it is very important that natural gas is detected though human senses (smell) as soon as possible, namely, an incidental gas leakage is detected easily. To this end, FGSZ mixes the colourless and odourless natural gas with special odorants: with a technical term, gas is „odorised”.

Import natural gas and gas from domestic production and storage can be fed into the Hungarian transportation system. Through the transportation system nodes, natural gas is transported to large consumers with direct supply (typically industrial consumers, power plants) and connected distribution systems. Natural gas is transported to end users (e.g.: households, industrial consumers) through distribution systems. The operation of these systems is the task of gas suppliers (distribution licensees). We operate gas delivery stations or filter-measuring stations at delivery points. For more information on natural gas transportation, see the infograph of FGSZ.

The Hungarian transportation system is an organic part of European natural gas pipeline systems. For more information, visit: ENTSOG website.
