RIO DE JANEIRO, BRAZIL – Paganini explained that green hydrogen is the name given to hydrogen resulting from a process of electrolysis in which water molecules separate the oxygen atom from those of this element, turning it into a flammable gas produced to be used as fuel.
It is called “green” because, in this case, electrolysis is produced with electricity from renewable energy sources, resulting in an industry with zero carbon emissions.
There is also gray and blue hydrogen, produced with electricity from fossil and natural gas energy sources, respectively, the latter being “more environmentally friendly than gray.” However, the government’s goal is to produce “blue” hydrogen, using electricity from fossil fuels and natural gas, respectively, which is produced with electricity from fossil fuels and natural gas.
The government intends to develop the green hydrogen industry, since, according to Paganini, it is “the remaining gap to eliminate oil,” prompting the “interest of countries that want to stop depending on oil.”
He explained that as it is a high-energy fuel, given its characteristics, it poses management challenges, being a more flammable material than naphtha, but that during the trip to Europe the ministry delegation witnessed the progress the industry is making in the handling of hydrogen, including cars adapted to this system with special tanks for its containment.
