Customers and security of supply to the territory – at the heart of our concerns
Adapting to make gas an energy of the future
Teréga has a public service mission. We guarantee the country’s security of gas supply and contribute to achieving France’s targets on the energy transition and energy frugality. Although the need to move our energy mix towards renewable, lower-carbon energies is already largely recognised, the energy crisis has made Europeans more acutely aware of their dependence on imported fossil fuels.

Securing and modernising our network
We undertake projects to modernise and develop our installations, to guarantee a quality service that meets the needs of the market.
In 2024, the total amount invested by us came to €154m.
For our Transport business, investment was mainly in grid maintenance and safety.
For our Storage business, investment was less than in 2023, when Teréga had made an exceptional cushion gas purchase (at €21m).
Actor in the territories
Our mission: to pursue and encourage the integration of renewable gases
ACTOR IN THE BIOMETHANE INDUSTRY:
10 sites in production
9 under construction

CATALYST FOR HYDROGEN DEVELOPMENT:
Contributor to the targets set by the Energy Transition for Green Growth Law (LTECV)
As a transporter, Teréga’s objective is for infrastructures to become an effective means of delivering hydrogen, thus enabling the development of this decarbonised energy carrier
Accelerator of the energy transition
Encouraging the development of renewable gases
H2
Decarbonised hydrogen could help us tackle two challenges at once:
accelerating the energy transition and strengthening France’s industrial fabric.
A variety of solutions are being researched to move across to decarbonised hydrogen production. They include electrolysis of water, and waste pyro-gasification.
As a gas expert, we are working on the compatibility of our existing structures and the conversion of our natural gas pipelines to hydrogen, to enable the injection of pure hydrogen into a dedicated transport grid.
In addition to projects such as H2med, Teréga has launched the HySoW project, a hydrogen transport and storage infrastructure, and a major element of the future European hydrogen backbone.
H2 project
The HySoW project, led by Teréga, is a 650 kilometre infrastructure of pipelines able to transport 16 TWh/year of decarbonised hydrogen across the whole of the South West.
This infrastructure will allow the transit of hydrogen in two directions – both East-West and West-East – between Marseille and Bordeaux, while supplying the territories of the greater Toulouse area, the Lacq industrial hub, and the ports of Bayonne and Port-la-Nouvelle.
HySOW is intended to interconnect with the H2med green energy corridor. It occupies a strategic position at the intersection of the two main components of H2Med: the Franco-Spanish Barcelona-Marseille (Bar-Mar) interconnection and the HY-FEN pipeline to northern France.
CO₂
CCUS (Carbon Capture, Utilisation and Storage) is a technology that contributes to reducing excess CO₂ by collecting it at its source of production and then storing it sustainably, or utilising it as a resource for different applications.
CO₂ is a greenhouse gas produced in particular by certain industrial processes. Its capture at the source of production, then its storage underground, can thus prevent it being released into the atmosphere. It is also possible to reuse CO₂ that has been captured and stored to produce synthetic methane or biofuels.
Over the past few years, Teréga has conducted a number of studies, to prepare its infrastructures to take in the CO₂ captured on local industrial premises or coming from other CO₂ hubs and neighbouring countries.
CO₂ project
PYCASSO: a project to decarbonise industry in the Far South West
This largescale industrial project is led by Lafarge and Teréga. This project should contribute to achieving carbon neutrality in the Pyrenean territories by 2040.
The aim is to capture CO₂, transport it, and then put it into permanent geological storage in depleted oil and gas fields in the Far South West, which represent safe and sustainable CO₂ storage capacity. In addition, part of that CO₂ could be utilised in a number of ways, for example by combining it with hydrogen to produce methane and methanol.
The PYCASSO project offers a solution for invigorating the territory’s industrial transition. The processing of residual CO₂ is the final stage of reducing greenhouse gas (GHG) emissions in industry.
Biomethane
Methanisation projects enable us to recycle waste, produce renewable energy, and create non-relocatable employment. The natural methanisation process consists in breaking down organic matter to produce biogas which, after treatment, can be injected into the grid as biomethane.
Biomethane production is supported by the French Government, particularly through the introduction of the biogas production certificate (CPB) scheme. At the end of September 2024, 710 facilities were injecting biomethane into French natural gas grids, representing installed capacity of 13.1 TWh GCV/year.
We support all biomethane project leaders, such as the industrial operator Fonroche in Villeneuve-sur-Lot, and agricultural methanisation projects AgriEnergies in Auros, Mélusine in Aillas and Garonne Biogaz in Le Pin.
Biomethane project
The Garonne Biogaz project, which came into existence through a cooperation between Thomas Pagliarin (an entrepreneur), Edouard Crubile, Hugo Sazy (farmers) and Teréga, aims to recover organic waste (agricultural material and biowaste) from the surrounding area (farms and mass catering) and transform it into biomethane.
Thanks to this biomethane production, the departments of Tarn-et-Garonne and Lot-et-Garonne will be able to benefit from locally-produced renewable gas.
Teréga has supported this biomethane producer from the project’s birth right through to its connection to our transport grid in 2023.
Synthetic methane
The methanation process which produces synthetic methane enables the recycling of CO₂ from other processes, such as methanisation, transforming it into methane by adding renewably sourced H2.
This means that methanation can double the energy production yield of a methanisation plant, while at the same time reducing its greenhouse gas emissions.
We make an active contribution to collaborative projects designed to produce synthetic methane at both the laboratory and industrial scales, supporting projects such as SOLIDIA, METHAMAG® and Jupiter 1000.
From 2028, Power-to-Methane units could be systematically installed at methanisation facilities and Power-to-Methane could make up as much as 25% of gas consumption by 2050 (36 TWh NCV).
Synthetic methane project
METHAMAG® is a new methanation process based on the use of magnetic induction. It provides a response to the challenges of storing renewable energy sources, while demonstrating energy performance that is vastly superior to that of other systems. The partnership between Teréga and Toulouse Tech Transfer is the practical outworking of Teréga’s commitment to accelerating renewable gases, and reaffirms its partnership-based innovation strategy.
The METHAMAG® technology provides the conversion of CO₂ into CH4 by hydrogenation, thus enabling the rollout of “Power-to-Gas” solutions based 100% on the storage of renewable energy sources.
NGV and BioNGV
Natural Gas for Vehicles is natural gas used as a fuel. It offers one of the best balances in terms of the environment and overall usage costs.
Its advantages: virtually zero fine particulate emissions, NOx emissions at half the Euro VI standard level, with the option to replace natural gas with biomethane, which is even greener: bioNGV.
Since 2021, two public filling stations at Damazan (Lot-et-Garonne) and Saint-Sulpice (Tarn) were commissioned on our network along with three private stations for our own fleet.
Multi-energy
In France, the different energy networks operate independently of one another, resulting in energy losses of between 25 and 60%.
The aim of multi-energies is to join up those networks, resulting in greater energy efficiency with optimised production closer to where consumers need it, energy transformation (electricity into hydrogen, for example, to allow storage) and energy storage for use at a later date.
Teréga has launched the IMPULSE 2025 project, a smart multi-energy grid that puts this approach into practice, adding energy complementarity.
Multi-energy project
The IMPULSE 2025 project hopes to roll out a smart multi-energy system over a multiplayer industrial platform with the aim of decarbonising all the activities on the site.
In this way, IMPULSE 2025 makes it possible to:
share multiple energy sources and direct them to new users;
reduce energy wastage by storing losses for use at a later date, or transforming them into an energy source that is in greater demand or more efficient in use.
2 phases:
2019 - 2024: Conclusive finalisation of the study conducted with a major industrial operator on the Lacq platform and launch of the ZIBaC* project.
2025 - 2027: Operational and economic feasibility study of the concept, demonstrating estimated benefits
Accelerator of the energy transition
Call for expressions of interest (AMI) H2 and CO2
In its strategy to move decarbonisation from words to deeds, in December 2022 Europe created an inventory of H2 and CO₂ infrastructure projects of potential community interest. In that process, projects put forward by Teréga (HySoW, Pycasso and H2med BARMAR as part of the established consortium) received significant support from tens of Stakeholders within our territory.
Teréga then decided to launch this CEI, with the aim of getting a more accurate picture of the needs of the different regional, national and European actors in H2 and CO₂ transport and storage. The results of this CEI will also help us develop the design of our projects to provide the best possible response to the needs of both actors and territories.

THE HY’TOURAINE & ARMOR HYDROGÈNE PROJECTS
The Hy’Touraine project is aimed at the deployment in the Indre-et-Loire department of an ecosystem for the production, distribution and utilisation of renewable hydrogen in the transport and industrial sectors. Teréga Solutions and Lhyfe joined forces to develop this project together. Lhyfe will develop the renewable H2 production part, and Teréga Solutions the Distribution part: safe usage, design, construction and operation of stations.
Since 2020, the CCI Côtes d’Armor, Saint Brieuc Armor Agglomération, Syndicat d'Énergie and Banque des Territoires have been working together on the development opportunities for the Armor Hydrogène project (GREEN H2 production), based on the acquisition of a fleet of H2 buses and household waste collection vehicles by St Brieuc Armor Agglomération. At the end of 2021, the partners selected the operator of the project following a call for expression of interest: VALOREM, supported by TEREGA Solutions.
Teréga Solutions is also a technical partner in major events:
H2 supplies for vehicles, monitoring, operation and safety at the Pure ETCR (Electric Tourism Car Racing) event,
H2 supplies for the Vendée Globe 2024 partners’ village.
CO₂
Solutions introduced by Teréga Solutions for Carbon:
Capture: Teréga Solutions supports businesses which are a source of incompressible CO₂ emissions, helping them develop infrastructures to capture that CO₂.
Collection, transport and distribution: Construction of the 100% customised logistics chain, adapted to the needs of all, via pipelines or other means (road, rail, sea or river transport).
Utilisation and storage: With the help of a network of expert partners, we support:
the sale of biogenic CO₂ to producers for its utilisation as e-molecules,
storage enabling the CO₂ to be isolated from the atmosphere over the long term,
temporary storage with a view to generating negative carbon credits that can be traded.
Biomethane Gas Mobility
Teréga’s calling is to energise and support the biomethane industry in taking its rightful place in an energy mix that is compatible with the challenges of the ecological transition.
Our work and attention are focused on autonomous and territory-based agricultural methanisation, comprising small- and medium-sized units, well integrated into the territories. This is “French-style” methanisation, consistent with the structure of the nation’s agricultural fabric and the environmental and social expectations of our fellow citizens.
Our ambition:
to become a trusted partner to farmers in conceiving, designing and building their methanisation project.
Biomethane Gas Mobility project
The STRAW-Berry project
The aim of the STRAW-Berry project is to set up a pilot biomethane production unit in Neuvy-Pailloux in the Indre Department of France, based on the innovative methanisation process developed by start-up DualMetha.
The DualMétha solution is the first to propose a hybrid methanisation system, combining dry discontinuous and liquid continuous systems, an immersion process that allows better temperature control and more complete decomposition of the material. Associated with DualMétha through its 20% shareholding, Teréga Solutions is supporting the rollout of this exclusive process.
