Baltic Exchange introduces biofuel blends in expansion of Emissions Calculator

(Posted on 12/03/25)

Baltic Exchange has introduced a series of green fuel options to its FuelEU voyage and compliance cost calculator as more shipowners, traders and charterers seek to understand the commercial implications of this regulation on their voyage costs.

Biodiesel, bio-LNG, bio-LPG, green methanol, green hydrogen and green ammonia have all been added to the calculator, either as green fuel or blend options. Baltic Exchange’s FuelEU Maritime calculator provides an overview of the cost implications for the selected option relative to the Baltic standard for that route. This will enable the market to factor any change in fuel selected or contemplated into their voyage cost estimates.

“Green fuels are expected to be very expensive initially, so will likely be blended into fossil-derived fuels initially, to achieve compliance with the new FuelEU Maritime regulation. For this reason and based on industry feedback, we have added a blend capability to Baltic Exchange’s FuelEU compliance and fuel cost calculator,” said Martin Crawford-Brunt, Emissions Lead at Baltic Exchange.

“Baltic Exchange is assisting the market by cutting through the considerable complexity of these regulations by providing a simple decision-making tool that estimates the voyage costs of the many fuel and blend alternatives quickly and simply,” he added.

These results of the calculations are all presented relative to the Baltic standard ship and route types, which is generally considered to be burning VLSFO in navigation outside ECA and MGO for waiting and port consumption. The output from these calculations shows the cost differential for the fuel under consideration with the entered speeds and consumptions of the test ship versus the market standard.

For example, a 115,000 dwt LR2 clean tanker operating on the TC20 Baltic route (Al Jubail – Rotterdam), assuming a standard speed of 11 knots with ballast consumption of 21 mt/day and laden consumption of VLSFO of 27 mt/day, stands to save nearly $30,000 in fuel costs if using a 35% B100 blend option.

Despite an increase in overall fuel costs, the amount saved for being in compliance with the FuelEU Maritime regulation will offset those costs and provide additional savings compared to burning purely VLSFO.

According to Baltic Exchange’s FuelEU Maritime Calculator, in this example, the vessel stands to save increasing amounts of costs on fuel as the ratio of biodiesel to VLSFO increases.
