REA Consult and GreenSinnergy GmbH are advancing Eco-Refinerías del Sur, a power-to-liquid Sustainable Aviation Fuel (SAF) project in Chubut, Argentina, and have begun formal engagement with institutional investors and prospective offtakers.
The project is being developed with local partners and consists of a large-scale SAF production facility with an initial target capacity of 100,000 tonnes per year, scalable to 500,000 tonnes annually, and commissioning targeted for the early 2030s. At full build-out, total capital investment is expected to reach approximately USD 2.5 billion. Eco-Refinerías del Sur is being prepared in alignment with Argentina’s Régimen de Incentivo a las Grandes Inversiones (RIGI), a framework intended to support capital-intensive infrastructure through long-term regulatory and fiscal stability. It counts with public support by the Chubut Province and has secured the totality of the required area for its full deployment.
Designed as an integrated system combining renewable power generation, green hydrogen production and synthetic fuel synthesis, the project is structured to meet the technical and financing requirements typically associated with infrastructure-scale assets. It comes amid tightening regulatory mandates in Europe and other major aviation markets, which are increasing pressure on airlines and fuel suppliers to secure SAF volumes. Global SAF production today accounts for well under 1% of total jet fuel consumption, while policy requirements and airline commitments are expected to drive demand growth over the coming decade, shifting investor focus toward scalable, financeable SAF production capacity.
Within this cooperation, GreenSinnergy acts as lead developer, overseeing technical design, permitting and execution, while REA Consult leads the financial and transaction structuring, coordinating investor engagement and aligning the capital framework with international investment standards. Both parties emphasised that early system-level integration is essential to bankability for projects combining renewables, hydrogen and fuel production.
Carlos Villalba, Managing Partner of GreenSinnergy GmbH: “This project brings together renewable power, hydrogen and fuel production into a single industrial system. Structuring it correctly from the outset is essential for scale, bankability and long-term execution.”
Rachel Andalaft, Director of REA Consult: “Integrated SAF projects require coordination across energy generation, conversion and offtake infrastructure. Our role is to structure this complexity into a coherent financing framework that strategic capital can support.”
For both partners, the project supports broader efforts to advance sustainable industrial development and decarbonisation in Latin America, while positioning the region as a competitive production base for next-generation aviation fuels serving international markets.
