Abstract

Utiskivanje vodika proizvedenog iz obnovljivih izvora energije u mrežu plinovoda, u dugoročnom smislu, može predstavljati način skladištenja obnovljive energije te djelomično dekarbonizirati plinsku industriju. S obzirom na vrlo veliki kapacitet mreže prirodnog plina u Europi, čak i niska stopa miješanja vodika znači apsorpciju velikih količina varijabilne obnovljive energije. Adekvatna koncentracija vodika pomiješanog s prirodnim plinom uvelike ovisi o značajkama postojeće mreže prirodnog plina, sastavu prirodnog plina i načinu krajnje primjene. Svaki element infrastrukture prirodnog plina ima različit stupanj prihvaćanja koncentracije vodika; međutim element koji ima najmanji stupanj prihvatljivosti koncentracije vodika određuje ukupnu dopuštenu koncentraciju vodika u transportnom sustavu prirodnog plina. Širom svijeta, stanje postojećih propisa i standarda za kvalitetu plina trenutno ograničava primjenu vodika. Treba ih ažurirati kako bi vodik imao priliku ispuniti svoj potencijal. Prilagodba nacionalnih propisa koji određuju granice dopuštenih koncentracija vodika u transportnom sustavu prirodnog plina pomogle bi da se omogući umješavanje i krene razvoj vodikovog tržišta.

Abstract (english)

Injecting hydrogen produced from renewable energy sources into the pipeline network can be a way of storing renewable energy and partially decarbonizing the gas industry. Because of Europe's very large gas network capacity, even low hydrogen mixing rates would mean absorbing significant amounts of variable renewable energy. The optimal concentrations of hydrogen mixing with natural gas significantly depend on the characteristics of the existing gas network, the composition of natural gas and the method of final application. Each element of the natural gas infrastructure has a different degree of acceptance of hydrogen concentration; however, the element with the lowest degree of acceptance of the hydrogen concentration determines the total permissible hydrogen concentration in the natural gas transmission system. Worldwide, the existing gas quality regulations and standards currently limit the hydrogen application. They need to be updated so that the hydrogen could reach its potential. Adaptation of national regulations which define the limits of permissible concentrations of conductors in the natural gas transmission system would enable the mixing and encourage the development of hydrogen.
