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, provides an overview of the potential for sustainable aviation fuel (SAF) development in four African countries: Kenya, Ethiopia, Nigeria, and South Africa. It aims to highlight the opportunities, challenges, and pathways for SAF adoption in the region, with a focus on techno-economic feasibility and policy implications.

Main Viewpoints

1. Growth of Africa's Aviation Sector

• Africa's aviation industry is expected to grow significantly, with passenger traffic projected to double by 2043 compared to 2023.
• This growth presents economic opportunities for increased connectivity, tourism, and trade, but also raises environmental concerns due to rising aviation emissions.

2. Importance of SAF

• Sustainable Aviation Fuels (SAF) are identified as critical for reducing the carbon footprint of the aviation sector and achieving net-zero emissions.
• SAF can reduce lifecycle greenhouse gas (GHG) emissions by up to 57% by 2050 compared to business-as-usual scenarios.
• The ICAO outlines a "basket of measures" for emission reduction, including SAF, which is considered a key component for the industry's sustainability.

3. Techno-Economic Assessment Approach

• The report uses a techno-economic analysis (TEA) to evaluate the feasibility of SAF production in the four countries.
• It highlights the cost structure, feedstock availability, and policy environments as key factors influencing SAF development.
• The analysis focuses on different production technologies and their associated feedstocks, such as:
  • Hydrotreated Esters and Fatty Acids (HEFA) in Kenya and Ethiopia
  • Alcohol-to-Jet (ATJ) in Ethiopia
  • Fischer-Tropsch (FT) in Ethiopia and Nigeria
  • Power-to-Liquid (PtL) in South Africa

4. Challenges and Opportunities

• SAF in Africa faces high production costs, logistical inefficiencies, and fragmented policy frameworks.
• Risk premiums and green premiums are significant in Africa, contributing to higher selling prices for SAF.
• Feedstock availability is abundant, but supply chain management is a critical factor for cost competitiveness.
• Investment needs are substantial, with a 4,000 BPD HEFA plant in Kenya requiring $235 million, while a 2,000 BPD MSW-FT facility in Ethiopia would require $547 million.
• Co-processing in Nigeria is a cost-effective method that leverages existing refinery infrastructure.
• PtL technology in South Africa, using green hydrogen and industrial waste carbon, is a promising but capital-intensive option.

5. Policy and Market Considerations

• The Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) is a key policy instrument that could support SAF adoption.
• The report outlines short-term, medium-term, and long-term recommendations for policy, investment, and infrastructure development.
• Greenhouse gas emissions from SAF production are analyzed, with a focus on the environmental impact of different feedstocks and technologies.

Key Information

1. Country-Specific Insights

2. Investment and Cost Considerations

• Capital Expenditure (CAPEX) varies significantly by country and technology:
  • Kenya: $235 million for a 4,000 BPD HEFA plant
  • Ethiopia: $376 million for a 1,445 BPD ATJ plant; $547 million for a 853 BPD FT plant
  • Nigeria: Co-processing can leverage existing refinery infrastructure, reducing CAPEX
  • South Africa: $156 million for a 1,000 BPD PtL plant (excluding green hydrogen costs)

3. Environmental and Economic Benefits

• Greenhouse Gas Emissions Reduction: SAF production from various feedstocks (UCO, castor oil, sugarcane, MSW) can significantly reduce emissions.
• Energy Security and Economic Resilience: Local SAF production can reduce reliance on imported jet fuel, conserve foreign exchange, and create value-added industries.
• Economic Diversification: Exporting SAF or selling through book-and-claim platforms offers new economic opportunities for African countries.

4. Technological Readiness and Risks

• Some SAF pathways, such as FT from MSW and ATJ from sugarcane, are at a low technology readiness level, introducing uncertainty in their feasibility and scalability.
• Operational challenges include managing feedstock impurities, optimizing conversion processes, and ensuring cost efficiency.
• Further R&D and pilot projects are essential to address these challenges and improve the viability of SAF technologies in Africa.

Conclusion and Recommendations

• Short-term (1–3 years): Focus on policy alignment, feedstock availability, and initial pilot projects.
• Medium-term (3–7 years): Develop infrastructure, support R&D, and encourage private sector participation.
• Long-term (7+ years): Scale SAF production, integrate into global markets, and establish a robust SAF supply chain in Africa.

The report emphasizes that Africa has the potential to become a key player in the global SAF industry, but this requires coordinated policy support, international partnerships, and strategic investments in infrastructure and technology.
