Renewable gases are 100% clean energy solutions that contribute to the development of a circular economy and enable us to move towards a carbon-neutral economy.

In addition, they are energy carriers that can provide flexibility and resilience to the energy system and contribute to security of supply, promoting the coupling of the gas and electricity sectors.

Through our Enagás Renovable subsidiary, we are involved in over 30 specific projects in the field of renewable gases and decarbonisation in Spain.


They can be transported via the gas infrastructure network


To accelerate these projects, Clean H2 Infra Fund is one of the shareholders of Enagás Renovable, with a 30% stake. Managed by Hy24, it is the world’s largest green hydrogen fund, a joint venture between Ardian and FiveT Hydrogen.

In addition, through Enagás Emprende and together with Alantra, we have a fund, Klima Energy Transition Fund, with a European scope to invest in innovative companies operating in the field of green transition, decarbonisation and renewable gases.

 In the decarbonisation process, existing infrastructure will be necessary and will be complemented by new infrastructure to transport renewable gases, especially hydrogen.

Enagás promotes the development of renewable gases as new key solutions for the energy transition.


Hydrogen is a new energy carrier that opens up major opportunities. There are different types, depending on the sources and production methods, but the only one that is 100% renewable is green hydrogen.


It is 100% clean energy with zero CO2 emissions throughout the production process.


It is produced by electrolysis of water from renewable electrical energy, such as solar or wind power. This process does not emit CO2 and splits the water molecules into hydrogen and oxygen. Thus, it is an effective solution for promoting the decarbonisation of all sectors.

Enagás is committed to developing green hydrogen, given its 100% renewable nature. This renewable gas has multiple advantages.


Biogas is a renewable gas that is essential for moving towards a sustainable economy. It has considerable potential for decarbonisation, as it can be used to produce electricity and heat, especially in industrial environments where electrification is not possible.

Biogas is obtained from waste, specifically, from the organic fraction of municipal waste, agri-food industries, sewage sludge, crop residues and livestock manure. 

The most advanced way of producing biogas is by anaerobic digestion, a process through which organic matter is decomposed through the action of microorganisms.


They are renewable and local and contribute to decarbonisation and the development of a circular economy


Its development allows territories and industries to produce local, storable and clean energy, which has a positive impact on the economy and employment in rural areas, facilitating a just energy transition.

For its part, biomethane is a renewable, local and storable source of energy with an already-available technology capable of short-term emissions reductions to contribute to the development of the circular economy and greater waste recovery. Its use also reduces atmospheric emissions.

It is produced by subjecting biogas to a process known as enrichment or upgrading. It is considered an essential energy carrier in order to meet European decarbonisation targets and to boost the development of the circular economy.

It can be transported via existing gas infrastructure and has multiple energy uses in all sectors, including those that are difficult to electrify, such as the heat-intensive industry. It can also be used by households and as a sustainable fuel for vehicles.
