ProQR – Climate-Neutral Alternative Fuels

Project details

Title: Climate Neutral Alternative Fuels (ProQR)
Commissioned by: German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU)
Country: Brazil
Lead executing agency: Brazilian Ministry of Science, Technology and Innovation (MCTI)
Overall term: 2017 to 2022



The demand for fuel in Brazil’s transportation sector is rising annually by around five percent. In the aviation sector, this growth is even more noticeable as new flight connections are increasingly offered to remote regions. This accelerates climate change and results in large logistical challenges for fuel suppliers.

The aviation industry’s commitment to climate neutral growth is only achievable in the medium term using non-fossil energy sources. Even with an increase in the production of ethanol and biodiesel, biofuels can only play a limited role in satisfying the growing demand.


An internationally useable reference case for the decentralised production and application of Power-to-Liquid Sustainable Aviation Fuels (PtL SAF) has been created.



PtL SAF, produced using wind and solar energy, is one possible solution for climate-friendly air transport. Brazil’s geographic location is ideal to meet the requirements; there is ample sunlight across the country for photovoltaic systems and many regions have constant wind or other climate-friendly, low-cost renewable energy sources.

Small local plants that produce fuel for aviation from renewable electricity not only contribute to climate-neutral aviation, but also produce efficiently in remote or isolated locations. The key element of the ProQR project will be a pilot plant in Brazil. The project supports the planning, funding, construction and operation of this plant. In the future, systems of this kind will be produced in series and used at airports throughout the world.

The Brazilian implementation partners are the Ministry of Science, Technology, Innovation and Communications (MCTIC) and the National Agency of Petroleum, Natural Gas and Biofuels (ANP). On the German side, apart from the Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH, the German Aerospace Center (DLR) contributes to the project.


All the parties involved are helping with the development and enhancement of technologies for climate neutral-fuels and the related technical expertise.

Under real conditions, the project proves that the production and use of electricity-based renewable fuels is economically feasible. This opens new possibilities for aviation and other areas of transportation where there is no potential for electromobility.

The results contribute to CO2-free transport – in Brazil and around the world.
