Renewable Natural Gas
With advancements in alternative gas technologies, RNG produced today comes from capturing emissions from existing waste streams found in landfills, wastewater treatment plants and animal manure. This renewable energy, in the form of RNG, can be processed and injected into natural gas pipelines to be used as a clean, reliable energy source for homes, businesses and electric generation. It can also be used as transportation fuel, providing a cleaner option than diesel.
How does the RNG life cycle work?
- Capturing Energy – Beginning the RNG journey at a landfill or a dairy, swine or poultry waste farm, emissions are captured from lagoons or digesters.
- Cleaning and Processing – The captured emissions are processed and cleaned to pipeline quality standards so that they can be injected into Piedmont’s system as RNG.
- Customer Use – The RNG is injected into Piedmont’s natural gas infrastructure to serve homes and businesses in a sustainable environment.
These quality standards ensure Piedmont’s ability to continue providing safe, reliable and affordable natural gas service to our customers.
