MASH Makes powers first vessel trial with bio bunker fuel from carbon-negative process

Global shipping company DS NORDEN and renewable energy company MASH Makes on Thursday (21 April) successfully completed the world’s first commercial vessel trial using biofuel produced from a carbon-negative process. 

The vessel operated on a roundtrip voyage from Singapore to Brazil, successfully using 65 tonnes of fuel blend with 20% MASH Makes biofuel in its auxiliary engine.

“This trial proves that MASH Makes’ biofuel is suitable for marine engines, and it marks an important milestone towards bringing the fuel into our operation,” said Henrik Røjel, Head of Decarbonisation and Climate Solutions, NORDEN.

The trial demonstrated that MASH Makes’ biofuel is technically a drop-in fuel, compatible with existing systems and capable of reducing reliance on fossil fuels in specific marine applications. 

The results point to a practical path for shipowners to cut emissions without waiting for new infrastructure.

If the new agreement by the International Maritime Organization (IMO) to cap and price excess emissions globally is ratified in October 2025, MASH Makes offers a solution that enables shipowners to start significantly reducing their emissions well before the agreement takes effect in 2028.

“Our biofuel meets the technical requirements of the shipping industry and can be used in unmodified engines. It’s a seamless, scalable alternative ready to cut emissions today,” said MASH Makes CEO Jakob Bejbro Andersen.

Unlike emerging fuels like green hydrogen or ammonia, which require new infrastructure, MASH Makes biofuel integrates directly with existing systems.

NORDEN acquired a minority stake in MASH Makes in 2023 to strengthen its future supply of renewable fuels. Since the acquisition, the two companies have worked closely together to validate the biofuel for marine usage.
