A method for modifying a methane-containing gas stream, comprising the steps: i) withdrawal of at least one substream from a methane-containing gas stream, ii) treatment of the substream with an electrically generated plasma, generating a modified gas composition that has a lower fraction of methane than the methane-containing stream used, and iii) return of the modified gas composition into the methane-containing gas stream, permits the storage of excess flow in a natural gas pipe grid.
