ALTERNATE has brought together a consortium of world leading, interdisciplinary experts in the field of air transport, engine certification and alternative fuels both from Europe and China, to provide synergy of the potential climate change mitigation strategies based on the use of alternative jet fuel pathways. An overview of the perceived needs and roadmap towards integration of alternative fuels in aviation sector is presented in with the specific aims and associated objectives of ALTERNATE detailed below.

Aim 1: Improve physical and climate models to include alternative aviation use.

  • Develop more reliable physical and climate models measurement methods for the potential alternative aviation fuel utilization.
  • Integration between policy and life cycle thinking.

Aim 2: Development of a reliable and globally harmonized LCA approach

  • Develop a reliable and globally harmonized LCA approach for the potential alternative aviation fuel supply chain on low cost, low energy consumption, low emissions.
  • Establish new LCA values for set of feedstock to fuel pathways based on this methodology.
  • Prepare a catalogue of feasible feedstocks/pathways for the 2020/2050 period.

Aim 3: Reduce the fuel cost and time cost in drop-in jet fuel certification.

  • Characterize different alternative fuels
  • Test different alternative fuels at laboratory scale.
  • Test and model alternative fuels in combustion chamber.
  • Conduct engine scale test.
  • Develop advanced sustainable fuels certification procedures.

Aim 4: Protocols and guidance for alternative fuel introduction in the aviation sector

  • Develop integrative tools and methods to support policies, regulations and practices for sustainable air transport.
  • Development including different regulatory approaches, and evaluate the effects on market demand.
  • Possible developments at worldwide scale, in China and in the EU.

The overall aim is to reach a Technology Readiness Level (TRL) of about 3 to 4, but the TRL level to be reached will vary between the different developments in the project (more details on TRL in the section 1.4 Ambition).
