H2 Valleys programme awards seven projects, ammonia dominates

Click to learn more about the €1.2 billion program, aiming to support the development of hydrogen valleys in Spain.
Launched in August 2024, the funding round aims to support the domestic production and use of electrolytic hydrogen in Spain via an industrial cluster approach. Projects had to meet criteria including:
- prior commitment from customer(s) to purchase 60% of hydrogen production
- hydrogen must be “renewable” as per EU guidelines for electrolysis
- electrolysis capacity must be more than 100 MW (with an exception for “grouping” of projects with at least 50 MW electrolysis capacity)
Among the seven winners are projects familiar to readers here at Ammonia Energy. Ammonia projects account for more than half of the €1.2 billion funding, and half of the installed electrolysis capacity:
