Study Confirms Ammonia Cuts Shipping GHG Emissions by Up to 61%

In the UK, an independent study by Sphera commissioned by the Society for Gas as a Marine Fuel has confirmed using ammonia as a marine fuel can achieve greenhouse gas (GHG) reductions of up to 61%, compared to current oil-based marine fuels.

Conducted according to International Organization for Standardization (ISO) standards and reviewed by experts from France, Germany, and the USA, the 1st Life Cycle GHG Emission Study on the Use of Ammonia as a Marine Fuel utilized the latest marine engine and supply chain data. It concluded that ammonia can significantly contribute to the International Maritime Organization’s (IMO) GHG reduction targets.

The comprehensive report assessed all major types of marine engines and global supply sources, incorporating data from manufacturers like Wärtsilä, Winterthur Gas & Diesel, MAN Energy Solutions, Yara Clean Ammonia, and BASF. It included emissions from supply chains and onboard combustion processes.

Mark Bell, GM of SGMF, expressed confidence that the study would provide the IMO with crucial information for regulatory decisions, while Dr. Oliver Schuller of Sphera highlighted the study’s adherence to ISO standards and rigorous independent review.
