I found two intresting calculators for the FuelEU Maritime regulation.
FuelEU Maritime calculator by zero44
This allows to estimate the vessel’s GHG intensity and the potential resulting non-compliance penalties. FuelEU Maritime
For example, the vessel with the highest fuel oil consumption in 2022 was a passenger ship with an EEDI (7.3 gCO₂/t·nm). Based on the THETIS public data, that vessel had a total fuel oil consuption of 42759 tons. If we assume the worst case scenario that the fuel consumed was only HFO and the exposure at EU is 100%, then the following FuelEU penalty is calculated for 2025.
But, taking into account only the penalty is not enough because one should consider the cost of the fuel as well. The second tool allows an estimation of the fuel cost as follows.
Thanks for sharing. It would be interesting to see how this evolves over time considering the GHG intensity limit reductions. My gut feeling is that at some point it would be more economical to consume sustainable fuel than to pay the Fuel EU penalty.
Good day,
In fact the idea behind Fuel EU regulation is decarbonization, but the target levels applied bring us to the theory, that (especially for the existing fleet) you cannot just “switch” to biodiesel (for example), but to commence considering it (small part of consumed fuel to be non-fossil fuel), i.e. if you “play” a little bit more with the zero44 calculator, you will find one theoretical biodiesel minimum, which once you mix it with the VLSFO used you will reduce the penalty to 0 (for example - 40’000 mts VLSFO (LFO) and only 1’500 mts biodiesel (total yearly 41’500 mts) would bring penalty to 0.
If you calculate whole year burning only biodiesel (where is the infrastructure and supply), you will get better GHG intensity number and it will be beneficial for pooling or banking/borrowing.
And of course, there will be difference from biodiesel to biodiesel and real figures shall be taken into account.
I’ve come across another calculator that I wanted to share with you.
The SAFE-T: Ship Alternative Fuel and Emissions - Toolkit is developed with funding from the U.S. Department of Transportation - Maritime Administration (MARAD) Maritime Environmental and Technical Assistance (META) Program.
This is about comparing the properties of different fuels. It’s interesting because this calculator offers the Well to Wake intensity of the fuels in terms of kgCO2/MJ.
Below, I’ve included some examples.
Comparison between HFO and Biodiesel (DIN EN 16258)
Here is another tool by Lowcarbonship that might be helpful.
Performance of Alternative Fuels for Ships
This calculator compares and quantifies the performance of various alternative fuels by using four performance indicators: cargo attainment rate, specific energy, specific cost, and carbon intensity indicator. The normalised score of various fuels is calculated based on the adjustable weights of each indicator.
The scientific part of the calculations is based on the findings in the lifecycle analysis of 22 marine fuel pathways, and fleet level analysis in the following scientific papers.
