We want to play an active role in the transformation of the energy sector and contribute value to the development of renewable gases, the reduction of polluting emissions and energy efficiency.

We participate in working groups and innovation projects at national and European level and in different R+D+I initiatives to promote the creation of sustainable models. In particular, we are members of European associations such as GERG (The European Gas Research Group), MARCOGAZ and Hydrogen Europe. At the national level, we are members of the board of trustees of the Hydrogen Foundation of Aragon and collaborate with the Catalonia Institute for Energy Research (IREC).

We work on innovation projects in the renewable hydrogen, the emissions reduction and the infrastructures fields.


Enagás shares a strong commitment with other TSOs and companies in the sector to accelerate the reduction of methane emissions at its facilities and support the EU’s climate ambition for 2030, as well as the 2050 climate neutrality targets.


The European Gas Research Group (GERG) and Enagás lead the pioneering research project ‘Top-Down Challenge’  aimed at promoting the use of new technologies for the quantification of methane emissions in midstream infrastructure.

This initiative, which has increased knowledge of new technologies to quantify and reduce methane emissions in this type of facility, highlights the important role of gas infrastructure in the energy transition process. 

The project is supported by Bureau Veritas and involves 13 other European gas infrastructure operators and gas associations. It is also aligned with the requirements of the UN Environment Programme (UNEP) OGMP 2.0 initiative and the European Commission’s objective to develop a regulation that improves the quantification of methane emissions in the energy sector and contributes to their further reduction.


The transmission of renewable gases through existing natural gas infrastructure requires a detailed analysis of the potential impact on existing network elements to ensure full compatibility. Enagás participates in several international projects to overcome these challenges.


A consortium of eight companies, including Enagás, and six research centres have joined forces to launch this project. GreenH2Pipes is aimed at promoting research and technology development to boost hydrogen production, its transmission through the gas network and its storage.

Enagás’ contribution to the initiative consists of facilitating the injection of hydrogen into the Gas System, eliminating possible existing barriers. It includes the conceptual design of a hydrogen injection plant and the construction of a test loop (HyLoop) at the Enagás Metrology and Innovation Centre in Zaragoza.

In addition, the company will participate in the validation of methods to ensure the quality of injected hydrogen, as well as technologies to separate hydrogen from natural gas. Furthermore, artificial intelligence will be used to optimise the operation of power-to-gas plants (facilities that convert electricity to hydrogen) and facilitate the integration of electricity and gas grids.

The project has received support under the Science and Innovation Missions 2021 programme of the Centre for the Development of Industrial Technology (CDTI).

The Metrology for decarbonising the gas grid project (DECARB), supported by European funds from the European Metrology Programme for Innovation and Research (EMPIR), aims to develop the metrology of renewable gases. It addresses the priority challenges of flow metering, gas composition, physical properties and safety — including monitoring of gas leaks — associated with the transmission of these renewable energies. In addition, CO2 metrology will be developed for carbon capture and storage.

This project, supported by European funds under the EMPIR programme, involves the accuracy, durability and intercomparison testing of gas meters for the measurement of renewable gases, and will develop calibration methods and standards to ensure their correct functioning.

The objective is to achieve a common European approach for assessing the compliance of commercially available meters with EN standards and the MID Directive, and to provide recommendations for adapting the designs and associated standards.

This project aims to put into practice the knowledge acquired in R+D projects by means of recommendations and guidelines for the adaptation of natural gas infrastructure for the injection of hydrogen.

Through GERG and CEN (European Committee for Standardisation), Enagás participates in the ‘Removing the technical barriers to use of hydrogen in natural gas networks and for (natural) gas end users’ project funded by the European Commission.

Enagás is a member of the advisory board of this European project that will carry out technical developments on hydrogen storage in a wide range of aquifers and depleted fields. The company will conduct technical and economic feasibility studies and will provide industry and energy policymakers with insights into underground hydrogen storage.

Enagás is committed to the energy transition process. We want to help accelerate this by supporting concrete R+D+I projects in technologies that facilitate the uptake of renewable gases, such as green hydrogen, biomethane and syngas, in different sectors.

This project aims to design, produce and validate cost-effective photocatalytic solar panels for the production of hydrogen from wastewater.

This technology has been successfully tested at laboratory scale and is protected by a European patent application. The project will therefore focus on the pilot-scale validation phase using real wastewater as feedstock and under natural sunlight, which will favour early market acceptance.

The process involves the degradation of aqueous pollutants, mostly organic, by solar photocatalytic reforming (photoreforming) under anaerobic conditions with concomitant hydrogen production.

We have partnered with LatemAluminium to develop a pioneering green hydrogen industrial project in Spain. It consists of promoting two renewable hydrogen production plants in two LatemAluminium factories in Castilla y León region, which will allow renewable energy to be produced for use in the aluminium manufacturing process.

The two companies will also promote a consortium to develop an R+D+I project to determine the admissible ranges for utilisation of green hydrogen as an alternative fuel in the molten aluminium production process.
