Hydrogen has been a versatile resource in industry since the early 20th century, when it was mainly used to produce fertilisers. Today, it plays an essential role in the energy transition, with applications in power generation, metallurgy and sustainable fuels. The International Energy Agency (IEA) estimates that 500 million tonnes of hydrogen will be needed annually by 2050, but the current supply is not sufficient. To close this gap, innovative solutions are needed, such as natural hydrogen, which is generated geologically underground and could help meet this demand.

Green hydrogen is a promising alternative thanks to advances in electrolysis, storage and transport. Meanwhile, natural hydrogen is emerging as another viable option to reduce emissions. Currently, several projects around the world are seeking to identify economically viable reserves. The development of new technologies, such as specialised software and aerogeophysical exploration, is accelerating this process. This positions natural hydrogen as a key resource for achieving a net-zero emissions future.

Benefits of hydrogen:

• Lower emissions: Reduces pollution in industry.

• Higher efficiency: Fuel cells convert energy optimally.

• Versatility: It can be produced from a variety of sources, such as water and biomass.

• Energy security: Local production reduces dependence on imported fossil fuels.
