We provide you with data related to the use of our LNG terminals :

  • incoming and outgoing commercial flows,
  • quantities of gas emitted to the onshore transport network,
  • stocks and capacities day by day.

We share this information in complete transparency.

For information, aggregated monthly nominations for unloading operations, net from reloads, received on 20/05/2026 for June 2026 were totalizing:

  • for Montoir LNG terminal:  7 600 GWh at 0 °C
  • for Fos Tonkin LNG terminal: 1 000 GWh at 0°C
  • for Fos Cavaou LNG terminal : 2 900 GWh at 25°C

Flows and inventories

Since the 3rd of March 2011, according to the Regulation (EC) 715/2009, ELENGY has published and updated daily the following information regarding :

  • Flows (nominated and allocated aggregated quantities),
  • Amount of gas in LNG facility,
  • Total and available capacities,

in order to comply with the new Transparency requirements as mentioned in the Article 19 and recalled here below :

" [...] Each LNG and storage system Operator shall make public the amount of gas in each storage or LNG facility, or group of storage facilities if that corresponds to the way in which the access is offered to system users, inflows and outflows, and the available storage and LNG facility capacities, including for those facilities exempted from third-party access. That information shall also be communicated to the transmission system operator, which shall make it public on an aggregated level per system or subsystem defined by the relevant points. The information shall be updated at least daily. [...]"

 

The information is sent in parallel to GRTgaz through Edigas messages, in order to be published by it on its own Transparency Plateform on an aggregated level per entry point from LNG facilities.

 

You can access the data thanks to the application below : choose a date and select the terminal to get the information wanted.

Our strategy

The energy sector is going through a period of upheaval that requires all its players, including Elengy, to reinvent themselves. That's why we launched our ‘Reinventing 2025’ corporate project in 2021. This was the start of a profound change, which we have translated into a strong ambition: ‘Successfully diversify into new gases and services to accelerate towards a carbon-neutral world.’

In 2023, this ambition is reflected in our new strategic priorities, which are resolutely focused on decarbonisation. 

Our 3 development priorities

Our LNG terminals, located at the crossroads of energy chains, will play a key role as import points for low-carbon molecules and export gateways for CO2 destined for permanent storage. Elengy will also play an active role in the development of liquefied biomethane (bioGNL) and low-carbon hydrogen.

From now on, Elengy is taking a decarbonising approach based on 3 main strategic priorities. 

Decarbonising our assets and activities

with the maintenance of our sites in operational condition, the improvement of our environmental impact and the accelerated switch to green LNG.

Decarbonising heavy mobility on land and sea

in which terminals and LNG play a central role.

Decarbonizing industries 

with imports of new low-carbon molecules (hydrogen, ammonia, etc.) and solutions for liquefying and exporting industrial CO2.

stratégie

New molecules in our terminals

Elengy is developing projects aimed at adapting its terminals to turn them into CO2 liquefaction and export sites, and developing them into decarbonisation hubs using ammonia. Elengy is actively promoting the introduction of e-methane production, which has the advantage of not requiring any adaptation of existing logistics chains or customer installations.

In addition, a new tax incentive introduced by the 2024 Finance Law (TIRUERT) will make it possible to market bioNGL at a price competitive with diesel, with no link to the market price of gas.  Drawing on our expertise in cryogenics and working with innovative partners, we are developing ‘on-farm’ liquefaction projects that are true models of the circular economy.

In this way, Elengy's terminals will become major infrastructures in the energy transition. 

CO2

CO2 is a colourless, odourless gas present in the atmosphere at 400 ppm (a figure that has been rising over the years). Unlike natural gas, it has to be compressed beyond 5 bars to become liquid.  It is a major greenhouse gas.  It is also a waste product subject to a European tax known as ‘CO2 quotas’. 

Ammonia

is a chemical compound with the formula NH3, which is gaseous under normal conditions of temperature and pressure. Liquid at -33°C, it can be easily transported, stored and moved by road, rail or pipeline. Tomorrow, it will be synthesised from green hydrogen and will be used to transport green hydrogen from one continent to another, and could be the fuel of the future to decarbonise the maritime sector.

E-methane

 is a synthetic gas produced from renewable hydrogen and recycled CO2. It is used to convert non-storable electricity into a storable renewable gas and recovers the CO2 released by industrial sites or extracted from biogas during the purification phase. It can be stored and injected directly into the grid, without prior adaptation of consumer infrastructures and installations. Thanks to e-methane, the CO2 released is given a new life, helping to reduce the overall carbon footprint.

Le bio-LNG

is the renewable, non-fossil fuel variant of LNG, produced from organic matter such as waste and residues. The organic matter is transformed into biogas in a fermenter. This biogas is then purified and liquefied to produce a gas with the same properties as liquefied natural gas.   With a carbon footprint more than 80% lower than that of diesel, it contributes to the objectives of decarbonising the heavy land and sea mobility sector, and to the consumption/production targets for renewable gas set by the French Energy Transition law.

Nos projets en développement

Aujourd’hui, Elengy a l’ambition de transformer ses terminaux méthaniers en hub multiservices de décarbonation, notamment pour les chaînes de capture et de stockage du carbone (CCS) ainsi que pour de nouvelles molécules : bio-GNL, hydrogène et ammoniac bas carbone.
