From Waste to Fuel: The Prospects for Renewable Natural Gas in the US
While hydrogen initiatives have been grabbing headlines thanks to large-scale national plans and projects at corporate level, renewable natural gas (RNG) also deserves attention as an emerging tool for decarbonization.
RNG comes from capturing biogas from areas like landfills and farms and then cleaning and upgrading that gas to remove excess carbon dioxide to then turn it into biomethane, which is more commonly referred to as RNG. This process is needed to bring the methane portion of biogas to a level that can then be blended with conventional natural gas on existing pipeline infrastructure, to avoid diminishing the quality or heat content of the pipeline.
