As part of their ongoing commitment to support greener shipping, Yara Marine has jointly commissioned a report to quantify the climate impact of scrubbers compared to low sulphur fuel oil.
“Well-to-wake, using HFO as fuel in combination with scrubbers generates less CO2 than using compliant fuel,” says Kai Låtun, Director in Yara Marine Technologies. He notes the report shows that use of compliant fuel could potentially generate as much as 25% increased CO2 emissions (see attached graph from the CE Delft report). “In real life this is probably not the case, but there is no doubt that using compliant fuels, all things considered, will result in three to five times higher CO2 emissions than using HFO as fuel in combination with scrubbers.”
In practice, there are two options for achieving compliance with MARPOL Annex VI Regulation 14. The first is using an exhaust gas cleaning system (EGCS) in combination with fuel oils with sulphur content higher than 0.50% or 0.10%. The second is burning fuel oil with a sulphur content of 0.50% / 0.10% or less…
