The fuel is the biofuel oil MR1-100 made from used cooking oil and supplied in Rotterdam, the Netherlands by GoodFuels. This was bunkered onto the Stena Immortal and would be used to test and show the technological and operational viability of the main engine in regular operations.

Biofuels are compatible with regular fuels but instead of fossil oil, they are made from biomass or biowaste. Although there are several forms of biofuel, Stena Bulk uses only 2nd generation fuel, meaning they are waste-based and therefore do not compete with food production. In this case, the combustible is made of used cooking oil.

When using this particular biofuel, CO2 reduction is about 83%. In this trial, we will minimize the emissions by 690 mt. These estimates are from the perspective of the life cycle, i.e. including the fuel production and distribution. Besides leading to a significant reduction in greenhouse gas emissions, the fuel often emits considerably lower rates of SOX relative to standard-compliant fuels.
