Spain and Portugal aim to become clean hydrogen hubs and net energy exporters, causing tensions with France which plans to produce its own hydrogen using nuclear energy.
The pipeline will only carry hydrogen in order to meet EU funding criteria, though "improvements" could be made in future to allow for some gas, a Spanish government source said.
As a result, the industry source said, they have pushed their four grid operators to "speed up technical studies, potential pipeline layouts and cost assessments".
