Sweden's Stena Bulk has become the latest owner to test out the potential of biofuels.
It is carrying out a trial of the eco-fuel over 10 days on its 50,000-dwt Stena Immortal (built 2016).
The vessel has been bunkered with 250 tonnes of the MR1-100 fuel at Rotterdam.
It is produced from used cooking oil and supplied by GoodFuels of the Netherlands.
The 100% biofuel will power the main engine in normal operations to test and prove the technical and operational feasibility.
Moving towards sustainable shipping
"By doing this test we want to contribute to pushing the industry and pave way towards more sustainable shipping," said Stena Bulk chief executive Erik Hanell.
"We want to be able to offer our customers additional options with less environmental impact in the future."
"By conducting the trial in normal operations, we want to show that being sustainable doesn't have to interfere with core business."
Biofuels are compatible with regular fuels but produced from biomass or biowaste instead of fossil oil.
Stena Bulk is using second-generation biofuels based on waste, so that its production does not compete with food production.
Stena Bulk said CO2 emissions can be cut by 83% with this MR1-100 blend. The trial will see 690 fewer tonnes released into the atmosphere.
The fuel also emits significantly lower levels of SOx than regular compliant bunkers.
Companies as diverse as Hapag-Lloyd, Norden, UECC and Samskip have also been testing out biofuels on their vessels.
