Over the past two decades, zero-emission aviation initiatives have focused on using drop-in biofuels and sustainable aviation fuels (SAF) to replace fossil-based jet fuels to achieve near-term reductions in carbon emissions with minimal impacts on the global aircraft fleet and supporting infrastructure. While significant advances have been made in the production of such fuels, scaling up manufacturing capability to provide cost-competitive drop-in fuels has been a challenge. This paper discusses ammonia as a carrier of electricity-derived, green hydrogen for aviation, with near-zero emission. Ammonia is proposed as both a carrier of hydrogen as fuel and to provide cooling for compressor intercooling and cooled cooling air for NOx elimination and condensation of water vapor in the exhaust to reduce contrail formation. The performance of ammonia with regard to all of these objectives will be evaluated. A detailed analysis of the energetics concerning the flow of ammonia from leaving the airport storage, to the fuel tanks of the aircraft to the wake of the engine will be performed. Conclusions will be drawn on how ammonia compares to Jet A, SAF, and hydrogen in overall performance as aviation fuel. |
