Spains His Majesty King Felipe VI, accompanied by the President of the Regional Government of Castilla-La Mancha Emiliano García-Page and the Chairman of Iberdrola Mr Ignacio Galán, inaugurated the company's green hydrogen plant in Puertollano in Ciudad Real. It is the largest facility of its kind for industrial use in Europe, and is also the largest plant currently operating in the world.This facility could make Spain a benchmark in the production and development of this new energy vector, which would make a decisive contribution to the decarbonisation of sectors that are difficult to electrify, such as fertilisers, high-temperature industry and heavy transport. With a total investment of 150 million euros, which includes both the green hydrogen facilities and a dedicated photovoltaic power plant, the Puertollano plant will be able to produce up to 3,000 tonnes of green hydrogen per year and avoid the emission of 78,000 tonnes of CO2 per year.The Puertollano plant will be able to generate 100% green hydrogen through one of the world's largest electrolysis systems.The project will have zero CO emissions2 thanks to the use of renewable energy from an innovative 100 MW solar photovoltaic plant integrated into the facility. This plant has bifacial panels and a lithium-ion battery system with a storage capacity of 20 MWh. Its bifacial modules allow for higher production, as they have two light-sensitive surfaces. It will thus have an annual output of around 156,000 MWh.
