What are biofuels? Feed stock Intermediates Conversion Bio-jet fuel Chemical Transestrification Polymerization … Crops/ annuals Sugarcane Grains Seeds Grass Etc… Fats and oils Additional conversion Starch Biochemical Fermentation Enzymatichydrolysis … Biodiesel Sugars Refining and purification Trees Hardwood Softwood Alcohols Cellulose Hemicellulose Lignin Thermochemical Fischer-Tropsch Pyrolysis Gasification … Biogas Marine biomass Micro-algae Macro-algae Hydrocarbons and natural oils Chemicals Combustion Waste Household Industrial Agricultural Power generation Process waste
Aviation has an impact on CO2 emissions Aviation is responsible for an estimated 500 million tons, or 1%, of annual anthropogenic CO2 emissions. Unchecked, the industry estimates the aviation sector will be responsible for over 5% of global emissions by 2020.(IPCC) 80 % of CO2 annually emitted by aircraft are from those flying more than 1,500 kilometers There is no alternative mode of practical transportand given the energy density of kerosene, there really is no alternative to liquid fuel either 15.614 billion gallons of jet fuel used in 2009 600 million gallons of biofuel a year by 2015(The Sustainable Aviation Fuel Group)

Not all biofuels are created equal • http://www.qantas.com.au/travel/airlines/sustainable-aviation-fuel/global/en • http://renewablejetfuels.org/ Sustainable Aviation Fuel (SAF) as defined by Quantas advanced jet turbine biofuel made from next generation biomass sources such as algae, municipal waste streams, waste tree oil and specially selected types of biomass energy crops which do not compete with food crops. To be acceptable for commercial use, SAF must: Be certified in accordance with the aviation industry's stringent safety and performance requirements Have a reduced lifecycle carbon emission compared to traditional fossil based jet fuel as well as meet comprehensive sustainability criteria Be a 'drop-in' alternative to traditional fossil based jet fuel to avoid costly redesign of engines, airframes or fuel delivery systems.
Sustainable Aviation Fuel Users Group (SAFUG) definition of sustainable biofuel Perform as well as, or better than, traditional fossil fuel jet kerosene from a technical perspective but with a smaller carbon lifecycle; Use only biomass feedstock sources that minimise biodiversity impacts, require minimal land, water, and energy to produce; Not compromise food security; Not jeopardise drinking water supplies; Provide socioeconomic value to local communities where biomass is grown.
EUs definition of sustainable biofuels • EU Directive 2009/28/EC (Renewable energy directive: RED) requires: • Proof of sustainability of biomass: • no production from no-go areas (high biodiversity or high carbon stocks), • sustainability of production and operations • monitor social sustainability and food security • Raw material should not be obtained from : • wetlands • continuously forested areas • from areas with 10‐30% canopy cover • from peatlands • if the status of the land has changed compared to its status in January 2008 • GHG savings: • biofuels and bio‐liquids must yield a GHG emission savings of at least 35% • (50% from 2017, 60% from production started after 2017) • Traceability and mass balance must be assured

Indirect land-use change (ILUC) may need to be considered Indirect land-use change (ILUC) occurs when the production of crops for biofuels in a given land pushes the previous activity to another location. The use of the new location to place the previous activity generates a land-use change attributable to the implantation of the biofuel crop. In other words, if the crops needed to make a particular batch of biofuels crops are grown on uncultivated land, this will cause direct land use change. If crops grown on existing arable land are used to make biofuels instead of food, this will likely cause ILUC because of the necessity to replace the food. Due to changes in the carbon stock of the soil and the biomass, indirect land-use change has consequences in the greenhouse gas (GHG) balance of a biofuel.

Trade… or will the fuel be used locally? The potential for international trade in biojet fuels appears to be high …at a blend of 10%, the potential trade of biojet fuel will be between 36.8 and 57.5 Mt by 2050. http://www3.weforum.org/docs/WEF_FutureIndustrialBiorefineries_Report_2010.pdf IEA report “The potential role of biofuels in commercial air transport - biojetfuel”)
Sustainable biofuels for the aviation industry will need support from all stakeholders • http://www.safug.org/assets/docs/SAFUG_Brochure.pdf Continued Advancement Needs: Government support for development of aviation biofuel consistent with international trade commitments Policies designed to accommodate the specificities of aviation Global harmonised sustainability criteria Further research to develop sustainable feed stocks
Conclusions Biofuel sustainability criteria defined by the industry are challenging, but needed Proving sustainability will require certification and traceability systems – new systems and added costs compared to fossil fuels Costs – current estimates are ca2.8-3.7 USD/gallon (0.74-0.97 $/litre) (Bauen et al., (2009)) Still a great degree of uncertainty over its production costs as aviation biofuels are not currently being produced on a commercial scale “There is no silver bullet and it is imperative that policy makers, governments, universities, airlines, farmers, refineries and R&D work together to tackle the fuel problems of the aviation industry. Major advances are also necessary in relation to logistics, regulatory frameworks, quality control management and adoption of appropriate sustainability certifications.” (IEA report “The potential role of biofuels in commercial air transport - biojetfuel”)
