DECARBONIZATION BEYOND ELECTRIFICATION
Green Gas
Biomethane derived from biogas, is a renewable, low carbon-footprint energy source generated from the breakdown of organic matter such as agricultural waste, manure, municipal waste, and plant material.
Fuel Operations With Clean Alternatives
Biomethane
used as a direct substitute for natural gas.
Synthetic Gas
created through power-to-gas technologies, provide a way to store excess renewable energy.
Green Hydrogen
used in industrial processes and transportation.
Biomethane is a renewable alternative to natural gas
Biomethane is derived from biogas processing, which is produced through the anaerobic digestion of agricultural residues, food waste, energy crops, landfill waste, and sewage.
Biomass to Biogas to Biomethane
Biomass is the feedstock for producing biogas through anaerobic digestion. To convert biogas into biomethane, the raw biogas undergoes an upgrading process, where impurities like carbon dioxide are removed. The result is a high-purity methane gas chemically equivalent to natural gas.
Biomethane certificates represent the green attributes of biomethane injected into the natural gas grid. They can be bought and sold separately from the physical gas to allow gas consumers to claim the environmental benefits of biomethane without directly sourcing it.
Biomethane certificates are typically issued through recognized certification schemes and registries that verify the production and sustainability of the biomethane. This provides assurance about the authenticity of the environmental claims.
European Renewable Gas Registry (ERGaR) and the Association of Issuing Bodies (AIB) harmonize the registries to facilitate the cross-border trade of certificates across Europe.
REDCert provides certification systems for sustainable biomass, biofuels, bioliquids (REDCert-EU), and agricultural raw materials for food, feed, and material use in industries like chemicals (REDCert²).
Standards and accounting practices around biomethane certificates are still evolving. Some initiatives, like CDP RE100 and SBTi, recognize biomethane certificates for emissions reporting and emissions inventory accounting. However, GHG Protocol guidance currently limits their use for scope 1 emissions reductions.
