MaritimeNH3 - Webinar #1:  Use of ammonia for ship propulsion: crucial issues in engines and fuel cells

In this webinar, we focus on some outstanding issues that must be addressed to enable the clean and efficient use of ammonia as a marine fuel.

  • For piston-engines there is a need for accurate assessment of the burning rate in premixed, spark-ignited combustion of partially-decomposed ammonia, and the related emissions.
  • For fuel cells there are still unknowns regarding possible degradation mechanisms and durability that needs further understanding.

The Green Platform project Ammonia Fuel Bunkering Network aims at realizing an ammonia fuel value chain for the first ammonia-fuelled ships. MaritimeNH3 is the competence-building part of the project. Here, SINTEF develops new knowledge to facilitate the implementation of ammonia as a safe and cost-efficient zero-carbon maritime fuel. Our research is focused on:

  • Simulations and experimental work to advance the development of NH3 propulsion, including both piston engines and high temperature fuel cells.
  • Techno-economic analysis and green-house-gas assessment of a Norwegian NH3 value chain for maritime transport.
  • Models and simulations of NH3 spills to improve risk mitigation for NH3 bunkering installations in a Nordic climate.
