Biogas and biomethane are pivotal in the transition to a net-zero energy system. Produced primarily through anaerobic digestion of wet biomass, biogas can be utilized locally for heating or upgraded to biomethane to replace natural gas. This conversion significantly reduces fossil fuel consumption and contributes to sustainable energy systems.
The IEA Bioenergy Task 37 highlights that biogas and biomethane offer flexible and sustainable solutions essential for the circular economy and environmental systems. These renewable gases are not just for energy production but also support long-term energy storage and applications in hard-to-abate sectors like heavy-duty transportation, high-temperature industrial processes, agriculture, and chemical production.
Biomethane, in particular, is a renewable gas with properties similar to natural gas, allowing it to integrate seamlessly into existing infrastructure. This minimizes the total cost of ownership for energy systems, leveraging existing gas distribution and utilization technologies. Biogas and biomethane systems are mature technologies that enhance energy security and environmental sustainability by reducing greenhouse gas emissions and providing renewable biofertilizers from digestate.
Furthermore, biogas systems can utilize a variety of organic feedstocks, including municipal waste, industrial residues, and agricultural by-products. This versatility helps reduce fugitive methane emissions from organic waste, providing a strategic component in biorefineries and circular economy models in agriculture. By employing cover crops, biogas production can be economically viable without compromising food production.
In summary, biogas and biomethane are integral to a net-zero future, offering diverse and customizable solutions that go beyond energy production to include significant environmental benefits. Their development and deployment, supported by regional-specific strategies and favorable policy frameworks, are essential for achieving sustainable and low-carbon energy systems.
