Pemex is looking into using geological hydrogen by 2030 to diversify its income sources, move forward with the energy transition, and cut its greenhouse gas emissions.

White hydrogen is emerging as an energy alternative with great potential. It is clean, renewable, and abundant. In addition, its production does not generate carbon, which reinforces its role in the transition to a more sustainable future.

Added to this is its high energy density, which allows for efficient use in different applications. It is also compatible with much of the existing infrastructure, which facilitates its integration into the market.

For these reasons, geological hydrogen is emerging as a strategic solution. It can respond to growing energy needs while helping to meet international climate commitments.

Geological hydrogen

Pemex has decided to explore low-carbon business opportunities. The goal is to advance energy generation projects that do not depend on fossil fuels.

In its 2025-2030 Strategic Plan, the company notes that these initiatives will be key. They will serve to diversify its sources of income while reducing the risks associated with the energy transition.

Looking ahead to 2030, the oil company is considering a wide range of options. These include wind, geothermal, and geological hydrogen energy. The use of biofuels, tidal, and wave energy is also being analyzed. Even the extraction of strategic minerals, such as lithium, is being considered to meet future demand.

Greenhouse gas emissions

Geological hydrogen generally refers to two sources of hydrogen: 

• Hydrogen deposits naturally confined in underground reservoirs (sometimes referred to as white hydrogen).
• Hydrogen that can be produced underground by stimulating the decomposition of water in specific types of rock. 

Today, hydrogen is mainly used in oil refining and ammonia production. However, its horizons are expanding. Emerging applications include energy storage, heating, and replacing natural gas in certain functions.

Assessing its carbon footprint is key. Clean fuels are measured through a life cycle analysis. This calculation includes all energy inputs and production processes. It is then compared to a benchmark linked to fossil fuels. Tax credits available for its use also depend on this.

As a clean energy source, geological hydrogen presents a strategic opportunity. It reduces dependence on fossil fuels and accelerates decarbonization. Sectors such as transportation, industry, and power generation would be the main beneficiaries.
