Ceará’s Green Hydrogen Hub Promises to Be One of the World’s Largest Undertakings and Already Has 16 Signatures from Interested Companies
Ceará has already accumulated more than 15 signatures from American, Asian, and European companies intending to participate in the state’s new green hydrogen hub, and estimates that by next week this number will increase to 20 interested companies, further boosting the future production of green hydrogen in Brazil.

After New Companies Sign, Ceará Will Have 20 Companies Involved in the Green Hydrogen Hub
According to the Secretary of Economic Development and Labor, Maia Júnior, in an exclusive interview for the O POVO portal, four new companies are looking to be part of Ceará’s green hydrogen project, and their signatures should be registered later this week.
After the new companies sign, the state will total 20 interested companies in the green hydrogen hub. Ceará’s green hydrogen undertaking promises to generate thousands of jobs and income for the state. The central idea of the project, which was presented in mid-February last year, will be installed at the Pecém Industrial and Port Complex (CIPP) in São Gonçalo do Amarante.

What Is Green Hydrogen and Why Do We Need It?
Green hydrogen is emerging as one of the main options for storing energy from renewable sources with hydrogen-based fuels, potentially transporting energy from renewable sources over long distances—from regions with abundant energy resources to areas with energy hunger thousands of kilometers away.
Green hydrogen was highlighted in several emission reduction promises at the UN Climate Conference, COP26, as a means to decarbonize the industry in general, long-distance freight, transport, and aviation. Governments and industry have recognized hydrogen as an important pillar of a net-zero economy.
How Green Hydrogen Differs from ‘Gray’ Hydrogen and Traditional High-Emission Blue Hydrogen?
Hydrogen is the simplest and smallest element in the periodic table. No matter how it is produced, it ends up with the same carbon-free molecule. However, the pathways to produce it are very diverse, as are the greenhouse gas emissions, such as carbon dioxide (CO2) and methane (CH4). Green hydrogen is defined as hydrogen produced by splitting water into hydrogen and oxygen using renewable electricity. This is a very different pathway compared to gray and blue.
Gray hydrogen is traditionally produced from methane (CH4), split with steam into CO2—the main culprit of climate change—and H2, hydrogen. Gray hydrogen has also increasingly been produced from coal, with significantly higher CO2 emissions per unit of hydrogen produced, so much so that it is often referred to as brown or black hydrogen instead of gray. Today it is produced on an industrial scale, with associated emissions comparable to the combined emissions of the United Kingdom and Indonesia. It has no transitional energy value; quite the opposite.
Blue hydrogen follows the same process as gray, with additional technologies needed to capture the CO2 produced when hydrogen is separated from methane (or coal) and store it long-term. It is not a color but rather a very broad gradient since not all the CO2 produced can be captured, and not all storage means are equally effective long-term. The main point is that by capturing a large part of the CO2, the climate impact of hydrogen production can be significantly reduced.
