The low energy density of existing battery technology makes the decarbonisation of the aviation industry extremely challenging. In addition to carbon trading and fuel efficiency improvements, sustainably sourced biofuels are seen as a key method of reducing the aviation sector’s emissions. As our fuel is derived from waste materials, it is classified under the EU’s Renewable Energy Directive criteria as a virtually carbon free source of biofuel.  
Before a fuel can be utilised in a commercial airliner, it must pass stringent fuel certification tests. Biofuels that are based upon short chain alcohols and esterified fatty acids are significantly different from conventional Jet A1, which raises considerable safety concerns. In contrast to this, our fuel is derived from Fischer-Tropsch methodology and is virtually identical in terms of chemical and physical properties to conventional jet fuel. Fischer-Tropsch based fuels already have an approved aviation fuel certification pathway through ASTM D7566 “Standard Specification for Aviation Turbine Fuel Containing Synthesized Hydrocarbons.” This significantly streamlines our fuel’s pathway to commercial application and enables us to blend our fuel into existing aviation supply chains without issue.  
Fuel supply volume is another important factor for the aviation industry, as over 14 billion litres per year are consumed by the UK sector alone. Our first demonstration unit will start producing fuel in the second half of 2018 and we estimate that we will have produced over 100,000 litres by the end of 2019. Our long term goal is to exponentially increase production to the point where we are producing over 250 million litres per year by 2030, with potential to produce well over a billion litres per year by 2040.
