Iberdrola is making progress on Europe's largest green hydrogen complex for industrial use, located in Puertollano in Spain with the selection of European company Nel Hydrogen Electrolyser, a division of Nel ASA, as its preferred supplier for the construction of the project's key component, a hydrogen production system using electrolysis. Nel's Proton PEM solution, deployed all across the world for several decades, will now be used a as part of a commercial green hydrogen project, with 20 MW of installed capacity.

The electricity utility is also working on leading the creation of a supply chain in Spain to develop electrolyser technology.

The EUR150 million green hydrogen project in Puertollano in Ciudad Real, the result of an alliance between Iberdrola and Fertiberia, will be operational in 2021. The complex will comprise a 100-MW solar photovoltaic plant, a lithium-ion battery system with a storage capacity of 20 MWh and a system for producing hydrogen by electrolysis of 20 MW. Its construction will create 700 jobs and, once operational, will prevent the emission of 48,000 tonnes CO2 per year.

The green hydrogen produced will be used in the Fertiberia ammonia factory in the same town. The plant is already one of the most efficient in the European Union, with a production capacity of over 200,000 tonnes per year. Fertiberia will adapt its plant to the use of green hydrogen for manufacturing green fertilizers, reducing the needs of natural gas in the plant It will be the first European company in the sector to develop a large-scale experience in the generation of green ammonia.

The plant is being built in a strategic location, an important industrial hub which includes the National Center of Hydrogen that advised both companies during the process.
