Aviation industry’s quest for a sustainable fuel: considerations of scale and modal opportunity carbon benefit

Are we on course for a sustainable biofuel-based aviation future?

“…Revisiting this position, Warshay et al showed that the pathway with the greater opportunity for carbon benefits (i.e., how much carbon is saved by using biofuels in different modes) is for biofuels to be used for aviation as surface transport decarbonizes. In other words, as ground-based transport gains in efficiency through wider adoption of electric vehicles and low-carbon electricity generation gains share, it makes more sense to use the high energy density liquid biofuels for those purposes that cannot follow along this path, including aviation [5].…”

How biofuels could take off

“…More importantly, increases in global air travel demand are projected to far outweigh efficiency gains through technological improvement (Kahn Ribeiro et al , 2007; WEF and Booz & Company, 2011), which will result in a significant gap in attempts to achieve carbon neutral growth. Figure 1 shows that to close the gap development and use of alternative fuels – among other measures – is essential (Warshay et al , 2011; European Advanced Biofuels Flight Path Initiative, 2011).…”

“…Aviation, having no alternative should be an exception (Schrader, 2012). In recognition of the small window of opportunity for sustainable biomass production, Warshay et al (2011) assessed modal opportunities of carbon benefits, i.e. how much carbon emissions can be avoided by using different feedstock in different biofuels production pathways for different transport modes.…”
