TotalEnergies and VNG, a German natural gas distribution company, have signed an agreement to initiate the future supply of green H₂ to the Leuna refinery operated by TotalEnergies. Under the agreement, green H₂ will be produced from renewable electricity with a 30-MW electrolyzer in Bad Lauchstädt, built and operated by VNG with its partner Uniper.

This agreement contributes to the decarbonization of the Leuna refinery and will reduce the site's CO₂ emissions by up to 80,000 tpy by 2030. Furthermore, the pipeline connection to the Bad Lauchstädt Energy Park will give the Leuna refinery access to the future European H₂ infrastructure and the international markets for green H₂.

"This project is fully in line with TotalEnergies' ambition to decarbonize all H₂ used in its European refineries by 2030. Our ambition is to replace the gray H₂ with low carbon H₂, representing a reduction of 3 MMtpy of CO₂ by 2030," said Jean-Marc Durand, Senior Vice President, TotalEnergies Refining Base Chemicals Europe.
