Swedish owner Stena Bulk is to expand the use of biofuels on its tankers following a test run this month.
It loaded 250 tonnes of the bunkers made from recycled cooking oil on to the 50,000-dwt MR Stena Immortal (built 2016) in Rotterdam.
The 10-day commercial trial went very well, said chief executive Erik Hannell.
The fuel, produced by Dutch group GoodFuels Marine, cuts greenhouse gas emissions by 83% and substantially reduces SOX emissions.
