Iberdrola will construct the largest green hydrogen plant for industrial use in Europe

Iberdrola has launched what will be the largest plant producing green hydrogen for industrial use in Europe. The Puertollano (Ciudad Real) plant will consist of a 100 MW photovoltaic solar plant, a lithium-ion battery system with a storage capacity of 20 MWh and one of the largest electrolytic hydrogen production systems in the world (20 MW). All from 100 % renewable sources.

Puertollano Green Hydrogen Plant

With an investment of 150 million euros, the initiative will create up to 700 jobs and prevent emissions of 39,000 tCO2/year. The green hydrogen produced there will be used Fertiberia's local ammonia plant.

This is already one of the most efficient plants in the European Union with a production capacity of more than 200,000 t/year. Fertiberia will update and modify the plant to be able to use the green hydrogen produced to manufacture green fertilisers.

The new plant, which will become operational in 2021, will be developed in the municipality of Puertollano, a prime location with an important industrial hub. It is also the location of the National Hydrogen Centre, which has advised on the project since its inception. In addition, the project will help advance the technological maturity of green hydrogen and make it a solution for efficient decarbonisation in the medium term.

In Spain alone, the annual production of hydrogen, which is used as a raw material in the refining, chemical and fertiliser industries, is 0.5 Mt H2/year and this generates emissions of 5 Mt CO2/year. Worldwide this figure grows to 830 Mt of CO2/year (more than 2 % of global emissions).

This is why Iberdrola has joined the Choose Renewable Hydrogen, initiative, through which companies in the energy sector are urging the European Commission to take appropriate measures to make the most of the potential of green hydrogen.

It is estimated that decarbonising global hydrogen production through the use of 100 % renewable energy would also increase electricity demand by over 10 %.


Iberdrola already operates 2,229 MW of renewable energy in Castilla-La Mancha which is mainly wind power and because of this the Castilla-La Mancha community has the second most "green" megawatts installed by the company. Beside these, it will develop three new photovoltaic projects more in the region with an installed capacity of 150 MW.
