Keeping the ammonia flame alive
The chemistry of ammonia flames shows that even a small dose of hydrogen can turn an unstable or near-extinction flame into a steadier source of clean power.

mmonia may be packed with hydrogen, nature’s lightest and most energydense carrier, and contain no carbon, but it is an oddly obstinate fuel. It ignites slowly, burns unstably and easily blows out — a temperamental quality that makes engineers skittish about using it in real turbines or engines. Yet its potential is too valuable to ignore. Finding out when and how ammonia keeps burning, especially under the intense pressures of real combustion systems, could help turn it into a practical low-carbon energy carrier.
