Close storage means that the digestate resulting from the digestion process is stored in a gas tight tank and the additional biogas released during storage is considered to be recovered for production of additional electricity or biomethane.
Shranjevanje v zaprtem prostoru pomeni, da se digestat, ki nastane v procesu presnove, shranjuje v rezervoarju, neprepustnem za plin, za dodatni bioplin, ki se sprosti med shranjevanjem, pa se šteje, da je predelan za proizvodnjo dodatne električne energije ali biometana.
