ProQR - promoting 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, Innovation and Communications (MCTIC)/ Ministério da Ciência, Tecnologia, Inovações e Comunicações (MCTIC)
Overall term: 2017 to 2022



The demand for fuel in Brazil’s transportation sector is rising annually by around five per cent. The increase is even more pronounced in the aviation sector with new flight connections being offered to increasingly remote regions. This accelerates climate change and results in huge logistical challenges for fuel supply.

The aviation industry is committed to climate neutral growth, which will only be achievable in the medium term through the use of non-fossil fuels. 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 applicable reference case for local production and the use of electricity-based renewable fuels for aviation has been created.



Electricity-based renewable fuels, produced using wind and solar energy, are one possible solution for climate-friendly air transport. Brazil is ideally placed to meet the requirements: there is plenty of sunlight across the country for photovoltaic systems, while many places have constant wind or other climate-friendly and low-cost renewable energy sources.

Small local power plants that produce fuel for aviation from renewable electricity not only contribute to climate neutral aviation, but can already produce economically at remote locations. The core element is a demonstration plant in Brazil. The project supports the planning, funding, construction and operation of this plant. In the future, plants of this kind are to be produced in series and used at remote airports in the Amazon region.

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). The Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH and the German Aerospace Center (DLR) are involved on the German side.


From the outset, the project has involved various Brazilian ministries, authorities, universities and other public institutions, as well as associations and companies. All the parties involved are helping to develop and enhance technologies for climate neutral fuels and develop technical expertise.

Under real conditions, the project proves that the production and use of electricity-based renewable fuels is economically feasible. This opens up 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.
