Ready4H2 held its 17th webinar on the status of hydrogen developments in Spain this week. José Manuel Pérez, Manager of Innovation with the largest DSO in Spain, Nedgia, presented an overview of the Spanish hydrogen landscape, covering national policy and regulatory developments, blending scenarios, the rise of hydrogen valleys and clusters, national export strategies, and the role of gas DSOs in the future Spanish hydrogen ecosystem.
The importance of gas DSOs in Spain is evident; the energy profile in Spain shows that more than 50% of Spain’s total energy consumption in 2050 will be supplied through DSO networks. Two complementary perspectives on hydrogen deployment are present in the Spanish case: the national government-issued Hydrogen Roadmap and the industry-led New Deal. Spain is seeing more development from the bottom-up, where gas DSOs play an important role - locally in industrial valleys and clusters and more regionally through interconnected regional grids, connecting ultimately to the planned hydrogen transmission backbone.
Hydrogen injection has already been introduced in the Spanish regulatory framework, with current blending thresholds set at 2–5%. 35 hydrogen projects are currently progressing, with blending seen as a practical pathway for early deployment. Several pilot projects have also demonstrated that blending levels of up to 20% are technically feasible in Spanish gas networks. Hydrogen will play a key role in Spain’s decarbonisation strategy, with blending, industrial demand, and phased infrastructure development forming the foundation of a scalable hydrogen ecosystem.
