Summary of "Fueling Africa's Flight: A Techno-Economic Assessment of Sustainable Aviation Fuels in Africa"
Core Content
This report, Fueling Africa's Flight: A Techno-Economic Assessment of Sustainable Aviation Fuels in Africa, presents an analysis of the potential for sustainable aviation fuel (SAF) production in four African countries: Kenya, Ethiopia, Nigeria, and South Africa. It outlines the techno-economic feasibility, feedstock availability, production technologies, and policy considerations for SAF development in these countries, with the aim of supporting Africa's transition to sustainable aviation practices.
The report emphasizes the importance of SAF in reducing aviation-related greenhouse gas (GHG) emissions and enhancing energy security, economic resilience, and foreign exchange conservation. It also identifies the challenges facing SAF development in Africa, such as high production costs, limited infrastructure, and fragmented policy frameworks.
Main Points
Aviation Sector Growth in Africa
- Africa's aviation sector is expected to grow significantly, with passenger traffic projected to double by 2043 compared to 2023.
- This growth brings economic opportunities such as increased connectivity, tourism, and trade.
- However, it also raises environmental concerns due to the rising carbon footprint of the sector.
Role of SAF in Sustainable Aviation
- SAF is identified as a key solution to reduce aviation emissions and support the transition to renewable energy.
- SAF can reduce lifecycle GHG emissions by up to 57% compared to conventional jet fuel by 2050.
- The International Civil Aviation Organization (ICAO) promotes SAF as part of its "basket of measures" to reduce emissions, including CORSIA (Carbon Offsetting and Reduction Scheme for International Aviation).
Techno-Economic Analysis
- The report uses a techno-economic approach to evaluate SAF production in the four countries.
- It highlights the cost structure, investment requirements, and potential outputs of SAF facilities.
- High risk and green premiums in Africa contribute to higher SAF selling prices compared to global averages.
- Policy scenarios are analyzed to assess their impact on minimum selling price (MSP) and feasibility of SAF production.
Country-Specific Insights
| Country | Production Technology | Feedstock | Favorable Contextual Aspects | Potential Cases |
|---|---|---|---|---|
| Kenya | HEFA | UCO, Castor Oil | Existing petroleum infrastructure, regional aviation hub, government commitment to energy transition, abundance of vegetable oils | $235 million investment could meet 15% of current jet fuel demand, with potential to meet 10% of projected 2030 demand |
| Ethiopia | ATJ, FT | Sugarcane/molasses, MSW | High jet fuel consumption, favorable climate for sugarcane, existing sugarcane facilities, large quantities of MSW, reliance on imported jet fuel | $376 million investment in ATJ for 1,445 BPD of SAF could meet 6% of jet fuel demand; $547 million investment in FT for 853 BPD SAF could meet 4% of demand |
| Nigeria | Co-processing | Lipids (vegetable oils, UCO, tallow, etc.) | Strategic Gulf of Guinea location, existing refinery infrastructure, jet fuel refining capabilities, abundance of vegetable oils | Co-processing could produce 3,321–5,950 BPD SAF without major new investments, reducing import dependence |
| South Africa | PtL | Green hydrogen, industrial waste carbon | Expertise in FT technology, ambitions for green hydrogen, availability of industrial waste carbon | $156 million investment in a 1,000 BPD PtL facility could produce 39 million liters of SAF annually, meeting 3% of jet fuel demand |
Challenges and Opportunities
- High production costs and limited infrastructure are major barriers to SAF adoption.
- Risk premiums (due to currency volatility) and green premiums (due to environmental benefits) contribute to the higher MSPs in Africa.
- Feedstock availability is abundant in many regions but requires improved supply chain management.
- Technological readiness for some SAF pathways is low, creating uncertainty in production and cost projections.
- Green hydrogen and industrial waste carbon are key inputs for PtL SAF in South Africa, but their costs are not included in the initial investment estimates.
Recommendations
- Short-term: Develop pilot projects and improve feedstock supply chains.
- Medium-term: Implement policy frameworks that support SAF production and reduce green and risk premiums.
- Long-term: Scale up SAF production capacity and integrate into the global sustainable aviation value chain.
Key Information
-
SAF Production Pathways:
- HEFA (Hydrotreated Esters and Fatty Acids) in Kenya.
- ATJ (Alcohol-to-Jet) and FT (Fischer-Tropsch) in Ethiopia.
- Co-processing in Nigeria.
- PtL (Power-to-Liquid) in South Africa.
-
Investment Requirements:
- Kenya: $235 million for a 4,000 BPD HEFA facility.
- Ethiopia: $376 million for ATJ, $547 million for FT.
- Nigeria: Co-processing can leverage existing infrastructure, reducing investment needs.
- South Africa: $156 million for a 1,000 BPD PtL facility (excluding green hydrogen costs).
-
Environmental Impact:
- SAF can reduce lifecycle GHG emissions significantly.
- The CORSIA framework is crucial for carbon offsetting and SAF incentives.
- MSW-FT and ATJ pathways offer promising carbon reduction potential.
-
Policy and Market Considerations:
- Policy support is essential to lower MSPs and green premiums.
- International partnerships and investment in technology are needed to enhance technological readiness.
- Economic diversification is a potential benefit of SAF production, especially through book-and-claim platforms.
Conclusion
This report provides a strategic overview of SAF development in Africa, emphasizing the economic and environmental benefits of local production. It highlights the opportunities for African countries to reduce import dependency, enhance energy security, and contribute to global climate goals. The challenges, including high costs, limited infrastructure, and technological uncertainties, must be addressed through policy support, international collaboration, and targeted investments. The four-country case studies offer actionable insights for scaling SAF production and integrating it into the global aviation sector.
