The planned hydrogen pipeline project connecting the Iberian peninsula to France will extend to Germany, the head of states of the two European countries announced on Sunday.

“The route of the pipeline being created for the transportation of hydrogen between Barcelona and Marseille will be brought to Germany," French president Emmanuel Macron said after a meeting with German chancellor Olaf Scholz in Paris.

The two heads of state spoke of “accelerating the energy transition and encouraging the production of decarbonised energy in Europe”, which is banking on hydrogen in a multi-pronged strategy to reduce its carbon emissions.
