Key Highlights:

• Ammonia offers high energy density without carbon emissions, making it a promising fuel alternative.
• Challenges with low reactivity? Cofiring with hydrogen or partially cracking ammonia might be the solution.
• Our study, conducted on an optical engine test rig, reveals that turbulent flame speeds of ammonia-based fuels can rival those of methane, even with low levels of ammonia cracking.
• This is caused by the stronger turbulence response of ammonia-based fuels, which makes them attractive candidates for highly turbulent engine applications.

Why it matters: These findings bring us closer to a sustainable, carbon-free future, with ammonia playing a crucial role in the next generation of energy systems.
