France, which relies on its aging nuclear fleet to generate electricity, is leading a campaign to count hydrogen made using nuclear power -- known as "red" hydrogen -- in the EU's new renewable energy targets, which currently focus on green hydrogen made using electricity from renewable sources. After much foot-dragging, French President Emmanuel Macron agreed to the hydrogen pipeline between Barcelona and Marseille in October, a deal formalised at a summit with Spanish counterpart Pedro Sanchez in Barcelona in January. In Madrid, officials say the row is a "misunderstanding" and they are willing to be flexible on red hydrogen in other legislation such as the gas market directive, but not in the renewables bill. "Red hydrogen cannot be renewable because nuclear is not an energy that can be considered as such. France wants this to include its red hydrogen but it must first be designated as renewable.
