High-speed schlieren videos of turbulent flames at engine conditions: CH4, NH3, crNH3 7.5%, crNH3 10.0% (c) LEC GmbH

 

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.
