IBERDROLA TO CONSTRUCT LARGE GREEN HYDOGEN PLANT IN SOUTHERN SPAIN
Iberdrola and Fertiberia have signed an agreement for the construction in Puertollano of the largest green hydrogen plant for industrial use in Europe, with an investment of 150 million euros. It will consist of a 100 MW solar photovoltaic plant, a lithium-ion battery system with a storage capacity of 20 MWh and one of the largest electrolysis hydrogen production systems in the world (20 MW).
Decarbonising the planet is one of the goals that countries around the world have set for 2050. To achieve this, decarbonising the production of an element like hydrogen, giving rise to green hydrogen, is one of the keys as this is currently responsible for more than 2 % of total global CO2 emissions.
This technology is based on the generation of hydrogen — a universal, light and highly reactive fuel — through a chemical process known as electrolysis. This method uses an electrical current to separate the hydrogen from the oxygen in water. If this electricity is obtained from renewable sources we will, therefore, produce energy without emitting carbon dioxide into the atmosphere.
As the IEA points out, this method of obtaining green hydrogen would save the 830 million tonnes of CO2 that are emitted annually when this gas is produced using fossil fuels. However, there are some questions about the viability of green hydrogen because of its high production cost; reasonable doubts that will disappear as the decarbonisation of the earth progresses and, consequently, the generation of renewable energy becomes cheaper.
