Fluxys is an independent gas infrastructure group headquartered at Kunstlaan 31 in Brussels, Belgium. It employs roughly 1,500 people in gas transmission and storage and in the handling of liquefied natural gas, and reports that its associated companies operate 28,000 kilometres of pipeline and LNG terminals with a combined regasification capacity of 485 terawatt hours a year. Its footprint covers Europe, the Middle East and South America, with terminals in Belgium, France, Greece and Chile and underground storage at Loenhout in Belgium.
Transmission, storage and LNG
The group's activities are organised around moving and storing molecules. Transmission covers the Belgian network and the pipelines of affiliated operators abroad; storage is concentrated at the Loenhout facility, which the group holds out as its underground gas storage site; and terminalling is delivered through the Zeebrugge terminal in Belgium, the Dunkerque terminal in France and further capacity in Greece and Chile. Beyond natural gas, Fluxys is building infrastructure for hydrogen, biomethane and carbon dioxide, and offers shippers tariffs, capacity booking tools, transparency data and a price simulator for its market zones. The Belgian business is run by Fluxys Belgium, a separately listed subsidiary on Euronext that owns and operates the national transmission, storage and LNG infrastructure.

Energy transition projects
Fluxys frames its transition work around creating a system that can handle low-carbon molecules and carbon dioxide alongside natural gas. In Germany the group worked with OGE to lay the first sections of a hydrogen network, operating within the national core network framework approved by the German government, which the company says mitigates investment risk. In Belgium, Fluxys c-grid is developing carbon transport infrastructure and the group has partnered with Elia Group to coordinate planning between gas and electricity infrastructure. The 2025 annual report discussion on the group's site notes that the hydrogen market is struggling to gain traction while the carbon dioxide market is gathering momentum, and sets out the infrastructure, with its storage capacity and ability to handle hydrogen and CO2, as the group's contribution to a lower-carbon energy mix.

Contacting the group
Fluxys does not publish a single general enquiry mailbox. Its contact page lists a press team, community relations, legal and human resources addresses, each with the same Brussels telephone number, and separates commercial enquiries by activity: transport, storage and Zeebrugge LNG each have their own address, as do hydrogen transport and carbon transport, with further addresses for the German, French, Swiss, Brazilian and Chilean operations. Emergencies are directed to the Belgian 112 service, and the group also maintains a damage-reporting route for works near its pipelines.
