Summary of Associated Gas Monetization via miniGTL Conversion

Core Content

This report provides an overview of the development and application of mini-Gas to Liquids (miniGTL) technologies aimed at converting flared gas into liquid fuels and chemicals. It highlights the progress made in the field over the past few years, the role of new technology providers, and the economic and environmental benefits of GTL projects.

Main Points

• Global Gas Flaring: Over 5 TCF (140 billion cubic meters) of gas is flared annually. Converting this gas via GTL could produce 500 million barrels per year of liquid fuels and chemicals worth approximately $35 billion.

• Environmental Impact: Eliminating gas flares would prevent around 350 million tons of CO₂ emissions annually, along with the removal of black carbon from the atmosphere.

• Economic Benefits: Utilizing flared gas for energy or liquid fuels can provide significant economic value. The report emphasizes the importance of finding the lowest cost feedstock and producing the most valuable products.

• Technology Advancements: MiniGTL technologies have matured over the past decade, enabling the conversion of flared gas into diesel, gasoline, methanol, DME, and other products. The report notes that 2014 was a turning point with the announcement of the first commercial miniGTL plants.

• Flare Size Applicability: Technologies are categorized based on their applicability to different flare sizes: small (below 1 MMscfd), medium (1–10 MMscfd), and large (above 10 MMscfd). Small-scale solutions are particularly suitable for flares under 1 MMscfd, while large-scale GTL plants are typically for flares over 10 MMscfd.

• Commercial Projects: The report outlines the first commercial miniGTL projects, including:

  • Juniper GTL by SGC Energia (1,100 bpd, $100 million CAPEX)
  • CompactGTL (2,500 bpd, $275 million CAPEX)
  • Greyrock (1,000 bpd, CAPEX not disclosed)
  • TIGAS (15,500 bpd, $1.7 billion CAPEX)

• New Technology Providers: The report introduces several new companies such as SGC Energia, Maverick Synfuels, AUM Energy, Greenway Innovative Energy, and Standard Alcohol Company of America (SACA), each offering different GTL-FT or methanol-based technologies.

• Technology Readiness: Companies are evaluated based on their readiness for commercial deployment. Some, like Primus Green Energy and Siluria, are close to commercialization, while others are still in the development or pilot phase.

• Partnerships and Funding: Several companies have secured funding and partnerships, such as Velocys and Red Rock Biofuels with a $80 million DOE grant, and EFT with Airbus for sustainable jet fuel.

• GGFR's Role: The Global Gas Flaring Reduction Partnership (GGFR) is actively involved in advising on the best technologies and facilitating connections between potential customers and GTL solution providers.

Key Technologies and Companies

Economic Considerations

• Cost Efficiency: The cost of capital expenditure (CAPEX) varies significantly across technologies, with some projects costing as low as $100 million for 1,100 bpd plants.

• Feedstock Flexibility: Technologies are being developed to handle a wide range of feedstocks, from dry gas to wet gas, and are adaptable to different flare volumes.

• Operational Costs: Ongoing reductions in capital and operational expenditures (OPEX) are making miniGTL more viable and attractive for oil producers.

Conclusion

The miniGTL industry is rapidly evolving, with more companies and technologies emerging to address the challenge of gas flaring. The report highlights that the future of GTL lies in smaller, more flexible plants that can be deployed at various flare sizes. The availability of these technologies is increasing, and the first commercial miniGTL plants are being built, which is a significant milestone in the effort to reduce gas flaring and monetize it effectively.
