The aireg members work together in three working groups and a task force to solve major issues around biofuels.
The aim of this working group is to determine the available types and quantities of feedstock for the production of biojet as well as the development of a roadmap for a highly efficient alternative aviation fuel industry. Key issues:
- Which feedstocks are suitable for the production of alternative aviation fuel? Short, medium and longer-term periods are considered.
- Which regions are significant for feedstock provision now and in the future? The global potential is taken into consideration.
- What quantities of biomass can be provided under what conditions? The assessment takes defined sustainability standards into account.
- What is the standard of technology for potential biofuel production processes? The opportunities arising in the coming decades are also considered.
- What are the estimated costs of the various technologies? The assessments include assumptions for different points in time.
- How can the environmental effects associated with biomass conversion be determined for the different points in time? Greenhouse gas emissions are the primary focus.
This work group is concerned with the specific aspects of using alternative aviation fuels and handles all tasks related to quality and certification of new biofuels. Key issues:
- What influence do biofuels have on engines, aircraft and infrastructure? Leading research institutes contribute to the scientific structure of the investigations.
- To what extent do individual aspects of the logistics supply chain need to be adjusted? Particular attention is paid to the needs of airlines as end users.
- How much biofuel is required within a specific period? Answers to this also make it possible to draw conclusions about the feasibility of specific climate targets.
- How can the quality of fuel supply and fuel logistics be maintained? Aviation biofuel producers not previously active in the market are also supported.
- How can the certification of new conversion technologies be accelerated? The working group co-operates with international organisations to answer questions of this nature.
- How do biofuels that are already approved behave in comparison with different types of conventional kerosene? Can specifications of Jet A-1 be adapted?
The main objective of this working group is to integrate the three pillars of sustainability – ecology, economy and society – into the entire value chain of aireg’s activities. Key issues:
- Which criteria do the various sustainability standards include? Analysis also serves to define a clear sustainability catalogue for aireg.
- Which feedstocks are promising from the perspective of aspects of sustainability? Scenarios are used to consider the provision of sustainable biofuel quantities.
- How are biofuels viewed in the context of emissions trading?
The main objective of the Task Force deals with economic aspects and potential production capacities of sustainable aviation fuels in Germany. Key issues:
- How can the marketability of sustainable aviation fuels which are in price competition with fossil fuels be established?
- How can an infrastructure (refineries for the production of sustainable jet fuel) for the reliable supply of sustainable fuels in Germany be built up in the next few years?
- How can the financing of refineries for the production of alternative kerosene be ensured?
