Summary of "Financing Solutions to Reduce Natural Gas Flaring and Methane Emissions"

Core Content

This report explores financing solutions for reducing natural gas flaring and methane emissions, emphasizing the importance of addressing the "missing middle" flares—those that are too small for traditional financing but still viable for monetization. It provides a framework for evaluating the financial feasibility of such projects and highlights the role of various investors and financial instruments in supporting these initiatives.

Main Points

• Gas Flaring and Methane Emissions: Gas flaring and methane emissions are significant contributors to greenhouse gas emissions, accounting for up to 12% of global energy sector emissions. Despite a 19% reduction in flaring since 2003, the "missing middle" flares remain under-addressed due to their size and economic viability.

• Financing Landscape: The report outlines different categories of investors, including project developers, equipment suppliers, strategic investment funds, and commercial banks, and discusses the applicability of various financing instruments such as transition bonds and sustainability-linked loans.

• Financial Modeling: Detailed financial models are provided for six technologies used in flaring and methane reduction projects, including gas-to-power (third-party and on-site use), gas delivery to existing pipeline and processing plants, compressed natural gas (CNG), and small-scale liquefied natural gas (SNG). These models are based on indicative assumptions and aim to support preliminary feasibility assessments.

• Case Studies: Six case studies are presented, covering a range of technologies and geographic locations. These include Aggreko, Hoerbiger, Mechero Energy, Galileo, the Nigerian Gas Flare Commercialisation Programme, and Crusoe Energy Systems. The case studies highlight the importance of regulatory frameworks, infrastructure, and innovative approaches in overcoming project challenges.

• Barriers to Financing: Several barriers hinder the financing and execution of FMR projects, including lack of prioritization by operators, regulatory challenges, infrastructure gaps, and macroeconomic risks. Additionally, the unpredictability of flare volumes and the volatility of end-product prices pose significant challenges.

Key Information

Technologies for Flaring Reduction

1. Gas-to-power (third-party use): Flared gas is converted to electricity and sold to external buyers.
2. Gas-to-power (on-site use): Flared gas is converted to electricity used directly by the oil operator.
3. Gas delivery to existing pipeline network: Flared gas is directed into existing infrastructure for transportation.
4. Gas delivery to existing gas processing plant: Flared gas is integrated into existing processing facilities.
5. Compressed natural gas (CNG): Flared gas is compressed and sold as a fuel.
6. Small-scale liquefied natural gas (SNG): Flared gas is liquefied for transport and sale.

Financial Attractiveness

• 10 mmscf/d flares: Offer double-digit internal rates of return (IRR).
• 5 mmscf/d flares: Provide positive but sometimes single-digit IRR.
• 1 mmscf/d flares: May have negative or single-digit IRR, requiring clustering to achieve economic viability.

Best Practices for FMR Projects

• Turnkey Solutions: Developers should offer comprehensive solutions covering design, procurement, installation, and operation.
• Modular Equipment: Flexibility in equipment deployment is crucial to adapt to changing flare profiles.
• Portfolio Approach: Clustering small flares under one project helps achieve economies of scale and reduce risk.
• Equity Financing: Given the risks involved, developers may need to provide equity or mobilize other equity sources.
• Strong Project Management: Coordination with multiple stakeholders is essential due to the complexity and geographic dispersion of flare sites.

Regulatory and Policy Considerations

• Regulatory Support: Effective regulations, such as flare fines and clear ownership rules, are vital for encouraging FMR projects.
• Nationally Determined Contributions (NDCs): Some countries have included flaring reduction in their NDCs, signaling a commitment to the issue.
• Transition Bonds and Loans: These are emerging financial instruments that could support FMR projects, although they are still in a small market niche.

Conclusion

The report underscores the need for innovative financing mechanisms and supportive regulatory environments to address the "missing middle" flares. It encourages operators and governments to view associated gas as an asset rather than a by-product, and highlights the potential for private investment in this sector as the world moves toward a low-carbon future.
