Bio-LNG - Well-to-Wake
Liquefied biomethane from anaerobic digestion (waste feedstock) or thermal gasification. WtW intensity often < 20 gCO₂e/MJ for waste-based pathways.
Tank-to-wake CO₂
2,750.00t
From Cf per MEPC.364(79)
Energy content
48,000GJ
LCV 48.0 MJ/kg
Well-to-wake GHG
720.0t CO₂e
15.0 gCO₂e/MJ WtW
Method
TTW CO₂ (t) = mass × Cf Energy (MJ) = mass (kg) × LCV (MJ/kg) WtW (t CO₂e) = Energy (MJ) × WtW factor (g/MJ) / 1e6
WtW factors include upstream extraction, processing, transport, plus tank-to-wake combustion and relevant CH₄/N₂O. FuelEU Maritime Annex II publishes the authoritative defaults.
