Task 60


The Progress of Advanced Marine Fuels

Purpose, Objectives and Key Question

This Task is established to create an assessment of fuel options that have emerged or significantly developed since the 2013 report (AMF Task 41). The outcome that participants wish to achieve is a better understanding of the potential and limitations of new marine fuel options. The key question that we wish to address is: “How can the new forms of advanced marine fuels contribute to carbon neutral shipping in the future?”


Activities will include surveys and assessments as well as experiments with methanol engines.

  • New IMO 2020 fuel specifications and the problem of standardizing biofuels
  • Engines for LNG/Liquefied Petroeum Gas (LPG) mixtures
  • Engines for methane/low carbon gas mixtures
  • Engines for ammonia and ammonia/hydrogen blends
  • Engines and vessels for methanol
  • Experiences with biofuels based on organic waste
  • After treatment systems for advanced marine fuel engines

Key Findings

We expect to find significant technological development in the use of alternative fuels in ship engines. Specific results to be delivered:

  • Denmark: Formal Task documents. A report on converting 4-stroke engines to methanol (DTI), survey of emission reduction systems (DTI) and a report on Ammonia combustion studies (DTU)
  • Finland: A report on legislation and technology for advanced marine fuels
  • Sweden: A report on advanced marine fuels for small engines
  • Switzerland: A report on Dual Fuel technology for large two-stroke engines and the effect of mixtures of methane and gases with lower carbon intensity
  • Korea: A report on LPG/LNG mixtures and Ammonia
  • USA: A summary report on past and ongoing experiences with alternative fuels for marine use
  • Canada: A survey report based on Black carbon and PM emission factors, that are broadly accepted by other jurisdictions, and relate to different types of marine fuels (heavy fuel oil, marine diesel oil and very low-sulfur fuel oil) and different type of marine engines (2-stroke, 4-stroke) along with scrubber technologies
  • China: A report on methanol technology and infrastructure for fishing vessels and watercraft
  • Austria: A report on the activities of LEC regarding large ship engines
