Gasum is a Nordic energy company based in Finland that supplies natural gas, liquefied natural gas (LNG), and renewable gas (biomethane/LBG) to industrial, transport, and energy customers. The company operates across Finland, Sweden, and Norway, providing gas sourcing, distribution, and related energy market services.
Gasum develops and operates biogas plants that upgrade biodegradable waste and industrial side streams into biomethane for grid injection, vehicle fuel, and industrial use. It also manages LNG and LBG logistics and bunkering for maritime and heavy-duty transport, and runs a network of gas filling stations. In addition to gas supply, the company offers portfolio management and balancing services for energy markets. Gasum is owned by the Finnish state and, following sector unbundling, is separate from Finland’s gas transmission system operator.
