Acelen Secures $1.5B for Bahia SAF Biorefinery in Brazil

Acelen Secures Funding for Major SAF Expansion

Acelen Renováveis, a subsidiary of Mubadala Capital, has successfully secured $1.5 billion in financing to initiate construction of its large-scale biorefinery in Bahia, Brazil. This capital injection, part of a broader $3 billion total investment plan, was provided by a consortium of financial institutions led by HSBC and the IFC (International Finance Corporation). The facility is set to become a cornerstone of Sustainable Aviation Fuel (SAF) production in South America, leveraging Brazil’s unique agricultural scale and industrial infrastructure to accelerate the global energy transition.

According to the project specifications, the facility will utilize HEFA (Hydroprocessed Esters and Fatty Acids) technology to convert plant-based oils into renewable fuels. Once operational in 2029, the refinery is projected to produce 1 billion liters of SAF and HVO (Hydrotreated Vegetable Oil) annually. This output is critical as the aviation industry faces mounting pressure to decarbonize through the adoption of low-carbon alternatives to conventional jet fuel.

Industry Impact and Regulatory Alignment

The project is strategically aligned with Brazil’s ProBioQAV (Programa Nacional de Combustível Sustentável de Aviação), established under the Fuel of the Future Law (Law No. 14,993/2024). This regulatory framework mandates that domestic airlines reduce emissions by 1% starting in 2027, with requirements scaling up to 10% by 2037. By establishing this domestic production hub, Acelen ensures that Brazilian carriers, including LATAM, Gol, and Azul, have a reliable local supply chain to meet these legal obligations.

Beyond domestic needs, the project serves international markets. European and North American carriers, which are currently navigating stringent blending mandates such as ReFuelEU, are expected to view Brazil as a primary source for high-quality, sustainable fuel imports. As noted by Acelen Renewables, the project integrates a 'seed-to-fuel' model by cultivating macaúba—a native Brazilian oilseed—on 180,000 hectares of previously degraded pastureland. This approach effectively avoids competition with food crops and aligns with international lifecycle emission standards.

Technical Analysis

The development of the Bahia facility represents a significant shift in the global SAF landscape. Historically, the industry has relied on limited supplies of used cooking oil and animal fats. By pivoting toward dedicated non-food agricultural feedstocks like macaúba, Acelen is addressing the primary bottleneck in feedstock availability. This trajectory mirrors the successful scaling of large-scale HEFA biorefineries, such as the Neste facility in Singapore, which demonstrated that high-capital-expenditure projects are essential for achieving the volume required by the global aviation sector.

However, the project faces ongoing scrutiny. According to industry analysts, the production cost of SAF remains significantly higher than conventional jet fuel, which could influence future airline operational costs. Additionally, environmental organizations have highlighted the importance of monitoring indirect land-use changes to ensure that the cultivation of new feedstocks does not inadvertently impact local biodiversity. These factors remain central to the Ministry of Mines and Energy oversight of the national energy transition strategy.

What Comes Next

The project timeline is anchored by key regulatory and operational milestones. The first major milestone occurs in 2027, when the ANAC (National Civil Aviation Agency) begins enforcement of the ProBioQAV mandate. Following this, Acelen is expected to commence full-scale operations at the Bahia biorefinery in 2029. Success will depend on the continued integration of the agricultural supply chain with the industrial refining capacity currently under development.
