Gasnät

Gasnät is the system of pipelines, facilities and related infrastructure that transports gas from production and import points to end users, such as households, businesses and power plants. While the term is most commonly used in Swedish contexts, gas networks generally include transmission networks that move gas over long distances at high pressure and distribution networks that deliver it to end users at lower pressures. The networks handle various gaseous fuels, most often natural gas, but increasingly biogas, biomethane and other renewable gases, with potential future integration of hydrogen in some regions.

Key components of a gasnät include the transmission pipeline system, which connects gas suppliers and import terminals to the distribution network; compression and pressure-regulating stations that maintain flow and pressure; metering and regulation stations for measurement and control; and the distribution network that delivers gas to consumers. Underground storage facilities, such as depleted gas fields, aquifers or salt caverns, and LNG terminals may also be part of the system to balance supply and demand. Gas quality control, odorization for leak detection, and safety mechanisms are essential elements of operation.

Operation and regulation of gas networks are typically governed to ensure reliability, safety, and fair access. In many jurisdictions the network is treated as a regulated natural monopoly, with unbundling requirements separating network operation from gas supply and third-party access rules to allow multiple suppliers to use the same infrastructure. Standards cover pressure management, safety, interoperability, and emergency response.

Market trends include the integration of renewable gases like biogas and biomethane, and ongoing research into hydrogen blending and future decarbonization strategies, while maintaining secure and flexible gas supply.
