B100 biofuel bunkering has increased markedly in Rotterdam during the opening eight months of 2026, according to a recent industry report.
ENGINE recorded 77 B100 fuel quality samples in Rotterdam between January and August 2026, a rise of 126% from the 34 samples logged in the same period a year earlier.
That increase lifted B100’s share of the port’s biofuel samples to almost a quarter, signalling a notable rise in the prevalence of this neat biodiesel among the samples ENGINE monitored.
Sources indicated the figures on 27 September 2026, citing ENGINE data and summarising the year-on-year change observed in the first eight months of 2026.
The raw counts and percentage change are straightforward: 77 samples this year compared with 34 in January to August 2025, representing the 126% growth ENGINE recorded.
Taken together, the numbers show B100 moving from a smaller fraction of tested biofuel samples to a position approaching one in four of such samples in the port over the measured interval.
Sample counts and proportional share
ENGINE’s sample tally is the definitive element in the report: 77 B100 quality checks between January and August 2026, compared with 34 in the same months of the prior year. The recorded rise more than doubled the absolute number of B100 samples and produced the near-25% share noted in the reports summary.
The statistics focus on samples recorded by ENGINE rather than total volumes bunkered, so they describe the composition of tested biofuel samples rather than measured quantities of fuel supplied through Rotterdam’s berthside networks.
What the figures show
The data presented by ENGINE and reported points to an increased presence of B100 among biofuel samples taken in Rotterdam during the first two-thirds of 2026. The change is evident in both the absolute sample count and the fuel’s rising share of the tested biofuel sample set.
Because the published notes relate solely to sample numbers and shares, they do not quantify the volumes of B100 supplied or the number of vessels bunkered with B100 during the period. The figures should therefore be read as a record of ENGINE’s sampling activity rather than a direct measure of cargo or sales volumes.
The reported shift in sample composition will be of interest to ship operators, suppliers and regulators monitoring uptake of neat biodiesel blends, but the available facts are limited to ENGINE’s recorded samples and the proportions derived from them. The reports item referenced these recorded data to highlight the year-on-year change through to 27 September 2026.
