We are SGMF, leading safe maritime decarbonisation.

SGMF is a non-governmental organisation committed to advancing safety and best practices in the utilisation of low and zero carbon marine fuels. As a membership-based and not-for-profit entity, SGMF endeavours to promote the safe and sustainable use of low and zero carbon marine fuels. Its primary mission involves developing, gathering, and disseminating industry-leading guidance to encourage responsible operations with low and zero carbon marine fuels in the maritime sector.

Since it was established in 2013, SGMF has been a pioneer in shaping the industry’s approach to methane/LNG. At present, its mandate encompasses a variety of new low and zero carbon marine fuels, providing guidance for the use of methanol, ammonia, and hydrogen. This expansion aligns with the evolving landscape of the marine fuel mix.

Here you will find a number of free resources to help to facilitate the transition towards a more sustainable future.

Ammonia Cuts Shipping GHG Emissions by up-to 61%. SGMF Study is the First To Confirm Significant Well-To-Wake Reduction

Ammonia Cuts Shipping GHG Emissions by up-to 61%. SGMF Study is the First To Confirm Significant Well-To-Wake Reduction

Peer-reviewed study declares definitive figures for GHG reduction potential with the use of ammonia as a marine fuel

 LONDON, 10th June 2024: An independent study has confirmed that greenhouse gas (GHG) reductions of up to 61% are now achievable from using ammonia as a marine fuel, depending on the marine technology employed. This figure is compared with the emissions of current oil-based marine fuels measured from well-to-wake (WtW)[1]. The 1st Life Cycle GHG Emission Study on the Use of Ammonia as a Marine Fuel from Sphera, a leading global provider of environmental, social and governance (ESG) performance and risk management software, data and consulting services, uses the latest available marine engine and supply chain data available to date.

The study, commissioned by SGMF, was conducted according to International Organization for Standardization (ISO) standards. It was also reviewed by a panel of leading independent academic experts from key institutions in France, Germany, and the USA. The analysis concluded that ammonia can “beyond question” contribute significantly to the International Maritime Organization’s (IMO) GHG reduction targets.

Commenting on the research, SGMF Chairman Tom Strang said: “This is an important piece of work by SGMF that will help inform the maritime sector on the use of ammonia as a marine fuel and reinforces the importance of working together across all the different decarbonisation pathways, and for me highlights why we are part of SGMF”.

This comprehensive report uses the latest primary data to assess all major types of marine engines and global sources of supply with quality data provided by original equipment manufacturers including Wärtsilä, Winterthur Gas & Diesel & MAN Energy Solutions, but also Yara Clean Ammonia, and BASF on the supply side. GHG emissions from the supply chains as well as emissions released during the onboard combustion process (slip) have been included in the analysis.

Strang added: “It is important that an independent organisation like SGMF provides quality independent reports such as this latest life cycle assessment (LCA). The industry needs credible information and this is a landmark report as far as ammonia as a marine fuel is concerned.”

Mark Bell, GM for SGMF, added: “We are confident this work will provide IMO with solid information that will contribute to its regulatory decisions. SGMF will continue to produce up-to-date data, now including ammonia (this study), methanol and hydrogen.”

Dr. Oliver Schuller, director sustainability consulting at Sphera, said: “The main goal of this study was to provide a fact-based report describing the life cycle GHG emissions on the use of ammonia as a marine fuel across the value chain from well-to-wake. The analysis followed the established international standards ISO 14040/44 on life cycle assessment and underwent a critical review by three independent experts.”

Navigating Green Seas-Emissions from Marine Fuels_March2024

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.
