Ship Universe Maritime Tool

Alternative Marine Fuel Comparison Calculator

Compare VLSFO, MGO, LNG, methanol, ammonia, biofuel and custom marine fuels on an energy-equivalent basis. Model fuel cost, required fuel mass, tank volume, CO₂ emissions, lifecycle GHG intensity, carbon cost, FuelEU planning value, conversion CAPEX, payback, NPV and break-even fuel pricing.

Energy Equivalent
Alternative fuel quantity is adjusted for LHV and engine efficiency
Commercial View
Fuel + carbon + FuelEU planning value + operating penalties
Investment View
CAPEX, payback, NPV, IRR, break-even fuel price and lifecycle benefit

Fuel Comparison Results

Simple energy-equivalent comparison

Enter fuel data
Enter annual fuel consumption and fuel prices to compare the baseline fuel with the alternative on an energy-equivalent basis.
Planning estimate only. Fuel properties, densities, lifecycle emissions and actual engine performance vary by specification, pathway, supplier, storage condition and fuel-consumer technology. FuelEU Maritime calculations require verified fuel, pathway and engine-specific data and may include pooling, banking, borrowing, RFNBO treatment and other regulatory provisions not modeled here. EU ETS exposure also depends on voyage scope and applicable surrender requirements. VLSFO should be classified by its actual ISO 8217 grade rather than sulfur content alone. Confirm contractual, technical and regulatory assumptions before investment or fuel-procurement decisions.
