On July 15, 2019, M.J. Bradley & Associates released a series of Issue Briefs on renewable natural gas (RNG). The Issue Briefs are intended to provide policymakers, regulators and other stakeholders with a better understanding of the current RNG market, key policy drivers, potential natural gas utility business models, and the economics of RNG. Renewable natural gas is pipeline quality natural gas derived from renewable energy resources. Today, the most common sources of RNG include landfills, animal manure, and wastewater. Additional sources include food waste, agricultural waste, woody biomass, and renewable electricity (power to gas). This Issue Brief focuses on utility business models to facilitate RNG use and development.
