The English version
Renewable fuels
Renewable fuels are liquid or gaseous fuels made from biomass. The starting materials are renewable raw materials such as energy crops, grain, forest biomass, residues and algae.
High quality, regenerative fuels for aviation
The conventional, petroleum-based aviation fuel is standardized worldwide. It is a jet A-1 kerosene. Fuels from renewable energies are designed as so-called drop-in fuels, i.e. they meet the same specification as conventional, petroleum-based aviation fuel. This makes them fully compatible and mixable. This means that they meet the very highest quality requirements and their use does not require any changes to the aircraft turbines. In addition, there are no technical obstacles to mixing with fossil kerosene in the airport tank farms, which also avoids infrastructure costs.
Sustainability as the top priority
Sustainability must have top priority in the manufacture and use of alternative fuels. Rising food prices, competition for water and negative land use changes in the course of sustainable fuel production must be prevented.
Under these conditions, the cultivation of raw materials for renewable fuels offers clear advantages: The emergence of a new agricultural branch in developing countries can serve as a catalyst for the further development of the cultivation region - sustainable agricultural practice creates jobs, promotes the expansion of local infrastructure and counteracts rural exodus.
National and international sustainability regulations already exist for the production of fuels from renewable resources. These initiatives and regulations must be coordinated in order to achieve global sustainability standards for fuels from alternative energies for aviation.
Need for further manufacturing processes
So far, five different manufacturing processes for regenerative aviation fuels have been approved; a number of other technologies are in the approval process. The more technologies that are approved in the future, the wider the choice of raw materials will be. This means that numerous regional supply chains can be created and CO2 emissions can be further reduced.
