Abstract

A method for modification of a methane-containing gas stream, comprising the steps of: 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 which comprises a lower fraction of methane than the methane-containing gas stream used and iii) return of modified gas composition into the methane-containing gas stream. This method makes possible the storage of excess power in a natural gas line grid.
