Hi-EFECTS results were presented at the 13th Mediterranean Combustion Symposium (June 2025). Lund University highlighted ammonia/diesel dual-fuel engine performance, showing reduced NOx and CO emissions but higher N₂O, stressing the need for further research.

Lund University researchers used DNS to study ammonia/n-heptane combustion under marine engine conditions. Their findings on flame interactions and emission pathways support the development of cleaner and more efficient ammonia-fueled engines.

Hi-EFECTS participated in the IEA TLM conference in Ischia, Italy (22–26 June 2025), where Prof. Ossi Kaario (Aalto University) presented the latest ammonia and hydrogen combustion research. The event gathered around 60 experts from 12 countries, fostering collaboration on cleaner energy solutions for marine applications.

Researchers from Aalto University simulated hydrogen-enriched methane flames in narrow crevices and studied how geometry and fuel composition affect flame propagation and emissions. The results support cleaner combustion system development under the Hi-EFECTS project.

Hi-EFECTS project partners met at NTNU Trondheim to review advancements in clean marine fuels. The meeting focused on hydrogen, ammonia, and methanol development, with research tours and collaborative discussions.

Aalto University’s latest publication under the Hi-EFECTS project explores how ammonia-hydrogen-air flames behave near walls. The results help improve combustion modeling for marine engines using cleaner fuels like ammonia and hydrogen.

Hi-EFECTS project was presented internationally at German Maritime Day 2025, focusing on the potential of carbonless liquid fuel blends for maritime use. The session explored blends of ammonia, water, and ammonium peroxide or hydrogen peroxide, discussing their climate benefits, associated risks, and the pressing need for further research on performance and safety.

Research paper assesses eight advanced retrofit systems for tugboats, highlighting trade-offs and opportunities in energy, environmental, technical, and economic performance.

Aalto University’s Hi-EFECTS team shares new research on ammonia-hydrogen flame behavior, offering insights to improve combustion and reduce emissions.
