CBG, RNG or Biomethane: Unique Names of Modern Biogas Across Countries?
Biogas, a renewable energy source derived from the anaerobic digestion of organic materials like agricultural residue, food waste, animal waste, and sewage sludge, is gaining global traction as a cleaner alternative to fossil fuels. Interestingly, its nomenclature varies significantly across countries, reflecting local priorities, technologies, and branding strategies.
In Europe, this purified form of biogas is often called“Biomethane” or simply “Green Gas”. Countries like Germany and Sweden use terms such as “Biogasaufbereitet” (upgraded biogas) and “Biogas på fordonsgas” (vehicle biogas) to emphasize its refined form for energy or transport. The European Union actively promotes biomethane under its green energy policies, highlighting its role in decarbonizing transport and heating.
In the United States, biomethane is widely recognized as RNG (Renewable Natural Gas). It is predominantly marketed for its compatibility with existing natural gas infrastructure, making it a preferred choice for utilities and transport fleets aiming to lower carbon footprints.
India, with its growing biogas sector, refers to biomethane as “Compressed Biogas (CBG)” or Bio-CNG, a term championed by government initiatives like the SATAT (Sustainable Alternative Towards Affordable Transportation) program. This name highlights its application in vehicular use, supporting India’s goals to reduce dependency on imported fuels.
In Latin America, particularly in Brazil, biomethane is often called “Biometano”, aligning with the region’s focus on bio-based energy solutions for transport and agriculture.
China, one of the largest producers of biogas, uses terms such as Green Natural Gas or Bio Natural Gas, reflecting its push for green energy in rural and urban settings.
Despite the varied names, the global goal remains consistent: to harness biogas as a sustainable and versatile energy source to combat climate change and promote energy security.
