The investment in hydrogen is one of the greatest opportunities of the global energy transition.

It is a crucial strategy for the decarbonization of the economy and the reduction of dependence on fossil fuels, while driving technological innovation and the creation of new sustainable markets.

What makes hydrogen so important?

The great versatility of this element allows its use in various areas:

• Industry – as a raw material for chemical and metallurgical processes;
• Heating – in buildings, thermal systems, and combustion equipment;
• Transport – as a clean fuel in vehicles, trucks, and trains.

Because it is storable and transportable, hydrogen can ensure energy stability and complement the intermittent production of solar and wind energy.

But to understand its true potential, it is essential to know how it is produced.

How is hydrogen produced?

H₂ does not exist in nature in its pure state.
It is obtained through energy-consuming processes and can then be used for direct combustion or in fuel cells that convert the gas into electricity.

There are two main production methods:

• Reformation (grey hydrogen)

Reformation involves subjecting fossil fuels (such as natural gas, diesel, or coal) to high temperatures, reacting the steam with hydrocarbons to generate hydrogen.
This process accounts for about 95% of global H₂ production, but it emits carbon dioxide (CO₂), which is why it is considered grey hydrogen.

• Electrolysis (green hydrogen)

Electrolysis uses electricity to separate water (H₂O) into hydrogen (H₂) and oxygen (O₂) through an electrolyzer.
When this electricity comes from 100% renewable sources, the result is green hydrogen – a completely clean fuel, with no carbon emissions from production to final consumption.

Green Hydrogen: the next step in the energy transition

Renewable green hydrogen is considered one of the most promising solutions to achieve carbon neutrality.
Its zero emissions, high energy efficiency, and ability to integrate with other renewable sources make it an essential pillar of the future economy.

Furthermore, H₂ can play a crucial role in sectors that are difficult to decarbonize, such as heavy transport, the chemical industry, and steel production — areas where electric batteries still have limitations.

International Examples

Countries like Japan and Germany are among the pioneers in hydrogen use:

• In Japan, H₂ is already considered the "fuel of the future." Hydrogen-powered cars have been developed that emit only water vapor.
• Germany, on the other hand, initially produced hydrogen from natural gas but is now converting its solar and wind power grid into green hydrogen, applying it in the industrial, energy, and transport sectors.

These examples show that hydrogen is more than just a technological bet – it is a structural transformation in how the world produces, stores, and consumes energy.

The future of energy is hydrogen

With the ongoing energy transition, H₂ will be one of the drivers of global decarbonization, accelerating the phase-out of fossil fuels and contributing to a clean, secure, and accessible energy system.

Its transformative potential is immense – and research into new ways of producing, storing, and utilizing this element is just beginning.

The future of sustainable energy is being shaped today, and green hydrogen is one of its most promising components.
