Navigating Green Seas-Emissions from Marine Fuels_March2024

Navigating Green Seas: Addressing Emissions from Low and Zero Carbon Marine Fuels sets out SGMF’s position on
the challenges presented by low and zero carbon marine fuels and their emissions. An emission reduction culture is proposed for managing fugitive, operational, and emergency releases, as well as fuel combustion emissions. The focus is on aligning maritime practices with global emission reduction targets, integrating an emission reduction culture into ship design and operations.

This paper provides a high-level summary of the principal greenhouse gases (GHG) and pollutants linked to the use of methane/liquefied natural gas (LNG), methanol, ammonia, and hydrogen, discussing their implications for both the environment and human health. In summary, the commitments to mitigate the effects of these fuels include a no-emission approach, addressing all GHG and pollutant emissions, adopting energy-efficient practices, identifying, and measuring emissions, enhancing vessel design, and continuous improvement in onboard practices.

Looking ahead, this paper also serves as a forerunner to future publications that will translate SGMF’s principles into practice. These forthcoming initiatives focus on the different challenges posed by each type of fuel, the progress that   has been made so far in emissions reduction, and a roadmap for continuous improvement. The goal is to facilitate the implementation of practical measures on board vessels.

New - Methanol as a marine fuel an introduction Version 1.0

Methanol as a marine fuel – an introduction serves as an overview of methanol (CH3OH) in the context of its potential use as a marine fuel. After discussing the wider marine fuels context, the publication covers essential
information about methanol, including:

• The nature of methanol: The Guide explains what methanol is and provides fundamental knowledge about its chemical composition and properties.
• Usage in marine applications: How methanol can be applied as a marine fuel and its compatibility with existing and future marine propulsion systems.
• Safety and environmental profile: The safety aspects of methanol, highlighting its flammability and environmental impact, and a discussion of the necessary safety measures and environmental
  considerations.
• Technical aspects: The technical considerations involved in using methanol as a marine fuel, encompassing engine compatibility, emissions and combustion processes.
• System design: Insights into the design aspects of systems needed for using methanol as a fuel in ships.
• Bunkering facilities and processes: The infrastructure and procedures essential for the efficient bunkering of methanol, including safety protocols.
• Training requirements: The importance of training for personnel involved in handling methanol as a marine fuel, emphasising safety and operational procedures.

While this Guide offers a high-level overview, its primary objective is to provide key information that will aid the emerging methanol-fuelled ship industry in its development and adoption of this alternative marine fuel.

New - Ammonia as a marine fuel an introduction Version 2.0

Ammonia as a Marine Fuel – An Introduction serves as a comprehensive overview of ammonia (NH3) in the context of its potential use as a marine fuel. After discussing the wider marine fuels context, the publication covers
essential information about ammonia, including: 

• The nature of ammonia: The guide explains what ammonia is; provides fundamental knowledge about its chemical composition and properties, how it is transported, its availability and regulation.
• Usage in marine applications: How ammonia can be applied as a marine fuel and its compatibility with existing and future marine propulsion systems.
• Safety and environmental profile: The safety aspects of ammonia, highlighting its toxicity and environmental impact and discussing the necessary safety measures and environmental considerations.
• Technical aspects: The technical considerations involved in using ammonia as a marine fuel, encompassing engine compatibility, emissions and combustion processes, as well as the current rules and standards.
• System design. Insights into the design aspects of systems required for using ammonia as a fuel in ships.
  • Bunkering facilities and processes: The infrastructure and procedures essential for the efficient bunkering of ammonia, including safety protocols. 
• Training requirements. The importance of training for personnel involved in handling ammonia as a marine fuel, emphasising safety and operational procedures.

While this Guide offers a high-level overview, its primary objective is to provide key knowledge that will aid the emerging ammonia-fuelled ship industry in its development and adoption of this alternative marine fuel.
