An independent study has confirmed that the use of ammonia as a marine fuel can reduce greenhouse gas (GHG) emissions by up to 61%. This significant decrease depends on the marine technology employed and compares with current emissions from petroleum-based marine fuels.
Ammonia as a marine fuel and decarbonization
The study, commissioned by the Society for Sustainable Marine Fuels Management (SGMF) and conducted by Sphera, uses the latest marine engine and supply chain data. The study follows the standards of the International Organization for Standardization (ISO) and has been reviewed by three academic experts from institutions in France, Germany and the United States. The results show that ammonia can contribute significantly to the GHG reduction targets of the International Maritime Organization (IMO).
The report also uses primary data from OEMs such as Wärtsilä, Winterthur Gas & Diesel and MAN Energy Solutions, as well as suppliers such as Yara Clean Ammonia and BASF. The analysis includes GHG emissions from supply chains. supply chains and emissions released during on-board combustion.
Dr. Oliver Schuller, director of sustainability consulting for Sphera commented that the main objective of the study was to provide a fact-based report on the life cycle GHG emissions of ammonia as a marine fuel. The analysis followed international standards ISO 14040/44.
Tom Strang, president of SGMF, highlighted the importance of this work, noting that it will help inform the maritime maritime sector about the use of ammonia as a marine fuel and that it reinforces the importance of working together for decarbonization.
He also stressed the relevance of an independent organization such as SGMF providing high quality reports.
For his part, Mark Bell, general manager of SGMF, expressed his confidence that this work will provide IMO with solid information for its regulatory decisions. SGMF will continue to produce updated data on ammonia, methanol and hydrogen as marine fuels.
