Sunborne reborn!
Presentation

Despite successfully demonstrating 56kW of controlled combustion of partially cracked ammonia in October 2023, Sunborne Systems was unable to secure Series A funding at the beginning of 2024. Since then, the co-founders have secured UK government funding to tackle two of the challenges set out for Series A funding: to further develop their patented catalysts and to address issues associated with ammonia slippage and NOx emissions. Future opportunities will be discussed.

How to give a chemical push to ammonia in a compression ignition engine?
Presentation

The initial work on direct additivation to ammonia in a Rapid Compression machine showed promising results and radical ignition delays and temperature reduction. From these tests on, tests conducted on a research mono-cylinder engine, with the help of the Prisme laboratory at the University of Orléans, demonstrated that the additive used in pilot fuels allowed for better controlled ignition than the pilot fuel alone, better and eased cycle to cycle stabilization and better power output. It also quite dramatically reduced the amount of pilot fuel needed. It seems that the additive helps to keep ammonia in the combustion event even…
