Vale orders first ethanol-powered Guaibamax bulk carriers to advance low-carbon shipping

Brazilian mining major Vale has partnered with Shandong Shipping Corporation to introduce the world’s first large ethanol-powered Guaibamax bulk carriers, according to Maritime Executive . The move strengthens Vale’s multi-fuel maritime strategy and signals growing industry interest in ethanol as a practical transition fuel for deep-sea ore transport.

 

The agreement covers two 325,000-DWT next-generation Guaibamax vessels under 25-year charter arrangements, with options for additional ships. Besides ethanol, the vessels will also operate on methanol and conventional fuel oil and remain adaptable for future conversion to LNG or ammonia, ensuring long-term fuel flexibility.

 

Each 340-meter ore carrier will feature five rotor sails, upgraded propulsion systems, hydrodynamic improvements, shaft generators, frequency converters, and silicone hull coatings. Together, these upgrades are expected to reduce greenhouse-gas emissions by around 15% compared with the current Guaibamax series.

 

Vale views ethanol as a scalable alternative fuel with operational advantages over ammonia, particularly in handling and safety. According to Vale’s shipping leadership, combining ethanol propulsion and wind-assist rotor sails places the company in a strong position within the sector’s long-term decarbonization transition.

 

From a lifecycle perspective, second-generation ethanol can cut emissions by up to 90% versus heavy fuel oil. Vale is already expanding ethanol trials beyond shipping to trucks and locomotives operating along the Vitória-Minas Railway corridor.

 

The ethanol-fuelled vessels will complement 10 methanol-capable dual-fuel Guaibamax ships scheduled for delivery from 2027 under earlier agreements with Shandong. All projects form part of Vale’s broader Ecoshipping program, which integrates alternative fuels and efficiency technologies across its chartered fleet.

 

Since deploying Valemax and later Guaibamax ore carriers, Vale has steadily improved transport efficiency. The company estimates these vessels can reduce CO₂-equivalent emissions by up to 41% compared with standard Capesize bulkers, reinforcing their role in long-haul iron-ore logistics decarbonization.
