As biogas production from an anaerobic reactor or fermenter varies a biogas buffer can ensure that the supply of biogas to the utilisation (e.g. gas engine or biogas boiler) and or flare will be stable . Enwell supplies biogas buffers in ISO container versions of 8' up to 40'. The biogas volumes of these gas buffers varies between 10-70 m3. If larger gas buffers are desired, we recommend double-membrane biogas holders.
