It is estimated by the Intergovernmental Panel on Climate Change (IPCC) that by the year 2100 the world will see a temperature change of 2.5–7.8 °C above the average for the years between 1850 and 1900 (Bernstein et al. 2007). The aviation industry contributes approximately 2% of total carbon emissions across all industrial sectors and air transportation growth is increasing rapidly due to globalization of trade and travel. Aviation has no credible near‐term fuel alternative in ethanol or electric power due to the energy density required although aviation fuel can be used in fuel cells to produce electricity locally in dispersed applications. Current jet fuel production processes require huge facilities that are complex ...
