Africa Gas Initiative Summary

Core Content

The Africa Gas Initiative (AGI) is a project initiated by the Joint UNDP/World Bank Energy Sector Management Assistance Programme (ESMAP), aimed at promoting the utilization of natural gas in Sub-Saharan Africa (SSA). The initiative focuses on reducing gas flaring, developing indigenous gas resources, and enhancing the use of gas for power generation, industry, and transformation into secondary energy carriers.

Main Objectives

• To reduce gas flaring and improve the utilization of natural gas in the region.
• To develop local and export gas markets.
• To increase economic benefits from gas substitution, reduced fuel imports, and increased oil product exports.
• To improve environmental conditions by reducing emissions from liquid fuel combustion and deforestation.

Key Areas of Focus

1. Gas Resources and Reserves:

   • SSA holds 141 Tcf of proven gas reserves, though the region is not rich in gas compared to other parts of the world.
   • Gas is primarily associated with oil fields, especially in the Gulf of Guinea, with Nigeria holding 80% of total reserves.
   • Non-associated gas reserves are found in southern and eastern Africa, but are limited in development due to lack of infrastructure and market mechanisms.

2. Gas Uses and Flaring:

   • Gas production in SSA is 1.8 Tcf, but over 70% is flared or vented due to lack of markets and infrastructure.
   • Only a few countries (e.g., Nigeria, Cote d'Ivoire) market gas for domestic and commercial use.
   • Gas flaring is a major environmental issue, contributing to 28% of global flaring despite representing only 2% of global production.

3. Flared Gas Recovery:

   • Flaring is primarily due to the absence of a proper regulatory framework and market access.
   • Recovery options include re-injection into oil wells to enhance recovery and utilization in power generation and industry.
   • Recovery projects are essential for reducing environmental impact and improving resource efficiency.

4. Natural Gas Markets:

   • There is potential to build new markets for natural gas in SSA.
   • Projects could include power generation, industrial applications, and conversion of gas into liquid fuels (GTL).
   • The AGI recommends developing gas-to-power (GTP) and gas-to-liquids (GTL) technologies to increase economic and environmental benefits.

5. Liquefied Petroleum Gas (LPG):

   • LPG has been overlooked for a long time but has significant potential in the region.
   • It can be used as a cleaner alternative to charcoal and wood, helping to mitigate deforestation.
   • Institutional and regulatory support is needed to enhance LPG supply and utilization.

6. Institutional and Regulatory Frameworks:

   • A new regulatory framework is required to support the development of gas downstream activities.
   • The AGI emphasizes the need for a competitive and transparent market environment.
   • Regulatory bodies should be established to ensure proper management of gas resources and their utilization.

Key Findings

• Gas Flaring:

  • Gas flaring in SSA accounts for 71% of total gas production, significantly higher than the global average of 4%.
  • Nigeria is the largest flaring country, with 965 Bcf of gas flared in 1998.

• Gas Market Potential:

  • Many SSA countries have substantial undeveloped gas reserves, with over 400 known oil and gas fields.
  • The AGI has identified key countries for development, including Angola, Cameroon, Congo, Cote d'Ivoire, Equatorial Guinea, and Gabon.

• Economic and Environmental Benefits:

  • Utilizing gas can reduce fuel imports and increase economic returns.
  • It also reduces emissions of greenhouse gases (GHG), carbon dioxide (CO₂), and methane (CH₄).
  • LPG can replace charcoal and wood, helping to reduce deforestation.

• Methodology:

  • The AGI follows a structured methodology with four phases: desk study, field visits, feasibility studies, and proposal refinement.
  • Data collection and analysis were conducted using traditional sources and questionnaires, with the support of local governments and operators.

Key Recommendations

• Establish a market-driven regulatory framework to support gas utilization.
• Develop gas-to-power (GTP) and gas-to-liquids (GTL) projects to diversify energy use.
• Improve institutional capacity and fiscal policies to support gas development.
• Encourage private sector involvement and public-private partnerships to enhance gas market development.
• Reduce gas flaring by promoting field re-injection and utilization in local industries.

Summary of Countries Analyzed

• Angola: Identified as a key gas producer with 1.7 Tcf reserves.
• Cameroon: Has 3.9 Tcf reserves and potential for gas utilization.
• Congo (DRC): Minimal reserves but potential for development.
• Cote d'Ivoire: Has a small gas reserve (1.1 Tcf) and is a focus for LPG and gas-to-power projects.
• Equatorial Guinea: 1.3 Tcf reserves with significant potential.
• Gabon: 1.2 Tcf reserves, with some gas utilization already in place.

Conclusion

The AGI has demonstrated the potential for gas utilization in SSA, especially in reducing flaring, enhancing market access, and improving environmental and economic outcomes. The initiative has received strong support from African governments and has laid the groundwork for future gas development and sector reform.
