How liquefied biomethane works

Liquefied biomethane (LBM) is renewable methane made from organic waste and agricultural residues. It works wherever LNG is used today. Here is how leftovers become fuel, step by step.

  • 7stations from manure to fuel and back to the field
  • 1/600of its gas volume once liquefied at about −162 °C
  • 0technical changes needed in engines that already run on LNG

    What upgrading changes

    Raw biogas is only partly methane. Upgrading removes the rest, so biomethane has the same quality as natural gas and can be fed into the public gas grid.

    Raw biogasTypical composition by volume
    • Methane around 60 %
    • CO₂ around 38 %
    • Other gases around 2 %

    Typical values for illustration. The exact mix depends on feedstock and plant.

    Why LBM from manure can go below zero

    LBM from manure is climate-positive: over its lifecycle it removes more CO₂ from the atmosphere than it emits. This is where that comes from.

    1. Manure releases methaneStored on the farm, manure gives off methane, a strong greenhouse gas.
    2. The digester captures itIn a sealed digester, that methane is collected instead of escaping.
    3. Avoided emissions countThe emissions avoided on the farm are credited to the fuel, which pushes its lifecycle value below zero.

    Lifecycle CO₂ compared with diesel

    Good to know

    +22 %more energy per tonne than diesel, for LNG and LBM alike.
    −90 %nitrogen oxide (NOₓ) emissions compared with diesel.
    −95 %sulphur oxide (SOₓ) emissions. LNG and LBM are virtually sulphur-free.
