aardgasnet

Aardgasnet is the system of pipelines, infrastructure and organizational structures used to transport natural gas from production or import points to end users within a country or region. It comprises high‑pressure transmission networks that carry gas over long distances and lower‑pressure distribution networks that deliver gas to homes, businesses and industry. The term is commonly used in Dutch-speaking contexts to denote the national natural gas grid.

Key components of an aardgasnet include transmission pipelines, distribution networks, compressor stations and pressure‑regulating stations, as well as metering and control facilities. Storage sites, such as underground gas fields or salt caverns, provide flexibility to balance supply and demand. Control centers monitor gas quality, pressure, flow and safety, while maintenance activities such as pipeline inspection and pigging help ensure reliability.

Operation involves moving gas from import or production sources through the transmission network to regional distribution networks, where pressure is reduced and gas is metered for customers. Operators balance supply and demand daily and coordinate maintenance, safety inspections and emergency response. Safety codes, standards and training govern construction, operation and monitoring to prevent leaks and protect infrastructure and people.

Regulation and market structure vary by country but typically involve independent energy regulators and unbundling of network operation from suppliers. Transmission System Operators manage the high‑pressure network, while Distribution System Operators oversee local grids. European network codes also facilitate cross‑border gas flows and security of supply.

Future developments may enable the injection of low‑carbon gases, such as biomethane or hydrogen blends, into the network. Ongoing priorities include reducing methane emissions, modernizing infrastructure, and ensuring reliability while supporting energy transition goals.
