Maersk Reports 2025 Renewable Fuel Consumption Halved Due to Increased Grey Methanol Use
In 2025, Maersk's renewable fuel consumption decreased to 1,524 GWh, primarily due to an increase in grey methanol utilization. The shift raises concerns about emissions and the costs associated with grey methanol relative to greener alternatives.

In 2025, Maersk's renewable fuel consumption dropped to 1,524 GWh from 3,034 GWh in 2024, marking the lowest level since 2021. The decline is attributed to a significant increase in grey methanol use, which has higher GHG emissions compared to conventional fuels.
The company reported that grey methanol cost $669/mt, significantly cheaper than green methanol at $988/mt, albeit more expensive than VLSFO at $476.50/mt. Maersk operates 21 dual-fuel vessels and considers grey methanol an interim solution for testing, with plans to transition to greener fuels.
By 2030, it aims to potentially consume 6 million mt/year of methanol. The firm is also expanding its fuel strategy to include LNG, with vessels expected to operate by 2027, underscoring the need for a diversified approach to achieve energy transition goals.
