LIFE-CYCLE GREENHOUSE GAS AND NONRENEWABLE ENERGY ASSESSMENT OF AMMONIA-DIESEL MIXTURES AS TRANSPORT FUEL

Abstract

The global warming potential (GWP) and non-renewable energy consumption (NREC) of using ammonia-diesel mix as transportation fuel were assessed. The environmental impacts in using ammonia produced from steam reforming and partial oxidation processes were considered and differentiated. The assessments were compared to the GWP and NREC of the conventional pure diesel-fueled transport. The results suggest that using the steam reforming ammonia – diesel mix would have lesser GWP compared to pure diesel. However, the partial oxidation ammonia – diesel fuel mix has higher GWP than pure diesel, also its NREC is the highest among the three fuel systems. The NRECs of steam reforming ammonia – diesel fuel and pure diesel fuel are similar. The results suggest that steam reforming ammonia – diesel fuel mixture may offer some advantages over pure diesel fuel in terms of reducing global warming potential.
