The Port of Rotterdam handled 17,644 cbm of bio-LNG in 2025, representing a more than sixfold increase from the 2,775 cbm bunkered in 2024, according to figures released by the port authority.

Maritime shipping bunkered 9.8 million tonnes of fuel in Rotterdam last year, an increase of 3,000 tonnes compared with 2024. For the first time, vessels bunkered more than 1 million cbm of LNG at the port, including the growing volume of bio-LNG.

Biomethanol bunkering also rose sharply, with 11,819 tonnes delivered in 2025 compared with 3,946 tonnes the previous year — a threefold increase.

However, the total volume of bio-blended fuels decreased by 14% compared with 2024. The port authority attributed this decline to increased availability of bio-blended fuels in Asia following the European Union’s imposition of anti-dumping duties on Chinese biodiesel.

From the third quarter of 2025 onwards, bio-blended fuel volumes began to recover following the dip in 2024, according to the port.

In April 2025, the first ship-to-ship ammonia transfer took place at a terminal quay in the Port of Rotterdam. The port described this as a step in preparing for vessels that will operate on green ammonia and wish to bunker the fuel in Rotterdam.

The figures indicate growing diversification in marine fuel types as the shipping industry explores alternatives to conventional fossil fuels.
