Biogas Could Meet 25% of Global Natural Gas Demand, Says IEA
A recent report from the International Energy Agency (IEA) suggests that biogas and biomethane have the potential to significantly reduce our reliance on fossil fuels, specifically natural gas. According to a news release from the Environment Innovation Information Organization (EIC) published on June 16, 2025, the IEA believes these renewable gases could meet as much as one-quarter of global natural gas demand.
What are Biogas and Biomethane?
-
Biogas: This is a renewable gas produced by the anaerobic digestion (breakdown without oxygen) of organic matter. Think of things like agricultural waste, food scraps, sewage sludge, and even manure. This natural process creates a gas mixture primarily composed of methane (CH4) and carbon dioxide (CO2), along with smaller amounts of other gases.
-
Biomethane: This is biogas that has been upgraded and purified to remove impurities, primarily carbon dioxide. The resulting gas is almost pure methane and is essentially equivalent to natural gas. This means it can be injected into existing natural gas pipelines and used in the same applications – heating, cooking, electricity generation, and as a fuel for vehicles.
Why is this Significant?
-
Reducing Greenhouse Gas Emissions: Biogas production is often carbon neutral (or even carbon negative in some cases). The organic matter used would decompose anyway, releasing methane into the atmosphere. Methane is a potent greenhouse gas, much more effective at trapping heat than carbon dioxide. By capturing the methane and using it as a fuel, we prevent it from entering the atmosphere and reduce our reliance on fossil natural gas, which releases carbon dioxide when burned.
-
Energy Security: Many countries rely heavily on imports of natural gas. Developing domestic biogas and biomethane production can enhance energy security by reducing dependence on foreign suppliers and utilizing locally available resources.
-
Waste Management: Biogas production provides a valuable outlet for dealing with organic waste. Instead of simply sending food scraps and agricultural residues to landfills (where they decompose and release methane), they can be used to generate energy.
-
Supporting Rural Economies: Biogas plants can be established in rural areas, providing jobs and income opportunities for farmers and local communities. The digestate (the solid and liquid residue left after anaerobic digestion) can also be used as a fertilizer, reducing the need for synthetic fertilizers.
How Could Biogas and Biomethane Meet 25% of Natural Gas Demand?
The IEA’s assessment likely considers several factors:
-
Abundant Resources: There is a vast amount of organic waste available globally that could be used for biogas production. The key is to collect and process it efficiently.
-
Technological Advancements: The technology for biogas production and upgrading is well-established and continuing to improve, leading to lower costs and higher efficiency.
-
Policy Support: Government policies, such as subsidies, mandates, and carbon pricing, can create a favorable environment for biogas and biomethane development.
-
Investment in Infrastructure: Expanding the network of biogas plants and upgrading infrastructure to inject biomethane into natural gas pipelines is essential to realizing the full potential of these renewable gases.
Challenges and Considerations:
-
Cost: Biogas production can be more expensive than natural gas production, although costs are declining. Government support and technological advancements are needed to make it more competitive.
-
Logistics: Collecting and transporting organic waste can be challenging and expensive. Optimizing logistics and establishing biogas plants near sources of waste is crucial.
-
Public Perception: Some people may have concerns about the odor associated with biogas plants or the use of waste as a feedstock. Effective communication and community engagement are important to address these concerns.
-
Sustainability: It is important to ensure that biogas production is truly sustainable and does not lead to unintended consequences, such as deforestation to grow energy crops.
Conclusion:
The IEA’s report highlights the significant potential of biogas and biomethane to contribute to a more sustainable energy future. While challenges remain, these renewable gases offer a promising pathway to reduce greenhouse gas emissions, enhance energy security, and promote waste management. With continued innovation, policy support, and investment in infrastructure, biogas and biomethane can play a vital role in meeting global energy demand and mitigating climate change. The EIC’s highlighting of this IEA report underscores the importance of this renewable energy source in Japan’s and the world’s transition to a cleaner energy mix.
