Methanol - Well-to-Wake by pathway
Grey (fossil natural-gas feedstock), bio (waste-derived), or e-methanol (electrolytic H₂ + captured CO₂). WtW intensities span 1–100 gCO₂e/MJ depending on pathway.
Tank-to-wake CO₂
1,375.00t
From Cf per MEPC.364(79)
Energy content
19,900GJ
LCV 19.9 MJ/kg
Well-to-wake GHG
1,972.1t CO₂e
99.1 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.
