World’s First Ethanol-Powered VLOC Moves Closer to Reality as Everllence Clears G80 Engine Test

Everllence has successfully tested and verified the G80 ME-LGIMe ethanol-capable two-stroke engine intended for the third vessel in Shandong Shipping’s ten-ship Guaibamax program for Vale. The engine completed R&D testing at HD Hyundai Heavy Industries’ Engine & Machinery division in South Korea and can operate on fuel oil, methanol, ethanol, or blends of methanol and ethanol. Everllence now says the vessel is scheduled for early 2027 delivery, potentially putting a 325,000-dwt ethanol-capable VLOC into service considerably earlier than previously expected.

The Ethanol VLOC Timeline Just Accelerated

The technology has moved from a laboratory engine to an identified commercial ship in roughly one year.

Date Milestone Technology Position Commercial Meaning Remaining Question
July 2025 Fleet contract 10 VLOCS
Vale signs 25-year charters with Shandong Shipping for ten 325,000-dwt Guaibamax vessels.
Methanol / fuel-oil dual-fuel propulsion with future flexibility built into the vessel design. Creates a standardized ten-ship platform that can absorb later fuel developments without starting from a completely new vessel design. Which ships in the series ultimately receive additional fuel capabilities?
Sept. 2025 Engine test ETHANOL RUN
Everllence successfully operates a 90-bore ME-LGIM engine on ethanol across all load points.
Testing indicates the existing liquid-gas-injection methanol platform can also combust ethanol. Reduces the amount of completely new engine architecture needed to introduce ethanol. Full-scale ship application and fuel-system optimization.
Feb. 2026 Development VALE + EVERLLENCE
Formal cooperation agreement targets G70 and G80 ethanol-capable engine development.
Ethanol development moves from general R&D toward Vale's actual newbuilding program. Creates a direct path between engine testing and one of the world's largest dry-bulk charter programs. Final ship selection and test validation.
April 2026 Dedicated ships 2029 PLAN
Vale announces two ethanol-primary Guaibamax vessels under separate 25-year arrangements with Shandong.
Ships designed for ethanol, methanol and bunker fuel, with additional retrofit pathways. Establishes ethanol as an intended primary marine fuel rather than simply an engine-test fuel. Whether an earlier vessel could demonstrate the technology first.
Sept. 2, 2026 R&D verified G80 VERIFIED
Everllence completes testing of the G80 ME-LGIMe engine at HHI-EMD.
Fuel oil, methanol, ethanol and methanol/ethanol blends are supported. Hardware is now assigned to the third ship in the existing ten-vessel program. Sea trials and actual commercial ethanol bunkering.
Early 2027 Vessel delivery LATEST TARGET
Everllence's current schedule for the third Shandong Shipping VLOC.
Potential world's-first commercial ethanol-capable VLOC. Could move real-world ethanol capability roughly two years ahead of Vale's previously announced 2029 dedicated ships. Will ethanol be available for the ship's initial commercial voyages?
Ethanol Energy ~26 MJ/kg
Roughly one-third higher than methanol by mass.
Methanol Energy ~19.7 MJ/kg
Lower fuel energy density increases required mass and tank volume.
Storage State Ambient Liquid
Neither alcohol requires LNG-style cryogenic storage.
IMO Safety Framework Already Exists
Methyl and ethyl alcohol are covered by common interim safety guidance.

Planning model: This is an energy-equivalence calculator, not an engine-performance model for the Shandong Shipping VLOC. Actual consumption depends on engine efficiency, pilot fuel, load profile, weather, rotor-sail contribution, fuel quality and auxiliary demand. Reference properties are editable assumptions based on typical published values. Fuel prices are example inputs only. Vale's 90% ethanol reduction applies to its stated best-case second-generation ethanol pathway; lifecycle performance depends on feedstock, production energy, transport and certification.
