Metanlager

Metanlager is a German term used in energy and environmental literature to refer to methane storage facilities or systems. The word combines Metan (methane) and Lager (storage or depot). In English, it is usually translated as methane storage facility or methane reservoir. The term is most commonly encountered in German-language technical and policy discussions about natural gas infrastructure and biogas deployment.

Scope and forms: Metanlager can denote underground storage in depleted natural gas fields, aquifers, or salt caverns; it can also refer to above-ground storage facilities, such as pressurized gas tanks or LNG plants, and to methane stored as part of biogas upgrading systems. In natural gas networks, metanlager provide seasonal storage to balance supply and demand.

Operations and safety: Operation involves injection and withdrawal cycles, compression, and continuous monitoring of pressure, temperature, and gas quality. Safety measures include leak detection, corrosion control, and adherence to gas quality and pipeline standards to prevent fugitive emissions.

Environmental and policy context: Methane storage supports grid reliability and energy security but carries environmental considerations due to methane's potency as a greenhouse gas. Modern metanlager emphasize minimizing leaks, efficient capture of vented gas during maintenance, and integration with carbon accounting and methane abatement strategies.
