Green hydrogen plant for industrial use

Europe's most ambitious innovation project to promote decarbonization of industrial sectors

100% renewable hydrogen for emission-free ammonia and fertilizer production

  • Icono Investment 150 M€
  • Icono Local jobs 1,000
  • CO₂ CO2 avoided emissions (1) 48,000 tCO2/year

Distribution network

The surplus energy generated in the photovoltaic plant is fed into the distribution network for commercialization.


Green hydrogen production

Sistema de producción

Green hydrogen is produced by electrolysis cells powered by both the energy generated by the photovoltaic plant and the battery energy storage system, in a process with no associated CO2 emissions and allowing the electrification of industrial sectors.

The production process is carried out with a polymer electrolysis system with a 20 MW power supply and a capacity to generate 360 kg/hour of hydrogen.


H2 tanks

H2 tanks

The storage of green hydrogen is essential to guarantee the stability of supply required by the Fertiberia plant and to make efficient use of renewable energy production. A total of 11 tanks that allow the storage of 6,000 kg of green H2 at 60 bars.

Each tank has a volume of 133 m3 and dimensions of 23.5 m height and 2.8 m in diameter. They weigh 77 tonnes empty and are made of a special steel with a sheet thickness of 4.5 cm to contain hydrogen, given the small size of this particle.




The project includes a 5MW lithium-ion battery system, with a storage capacity of 20MWh, which allows for greater plant manageability and optimisation of control strategies.


Puertollano II photovoltaic plant

Planta foltovoltaica

The new facility for the production of green H2 from 100% renewable sources consists of a solar photovoltaic plant with an installed capacity of 100 MW.

The installation incorporates state-of-the-art technologies, such as bifacial panels, which allow for higher production by having two light-sensitive surfaces, and string inverters, which improve performance and make better use of the surface area.


Underground power line

Dedicated underground power line for exclusive use to ensure that all energy used in the electrolyser is renewable and environmental impact is minimised.
