What is renewable natural gas?

What do cows and trash have in common?

They are both sources of renewable natural gas and key to several Williams partnerships.

Williams is partnering with a dairy farm in Washington that is turning methane from cow manure into renewable natural gas. Williams built the necessary infrastructure in 2019 to connect the biogas to our Northwest Pipeline.

This project is expected to convert 150,000 gallons per day of dairy waste from up to 7,000 cows at the dairy into 160,000 MMBtu of renewable natural gas each year – the equivalent of 1.4 million gallons of gasoline. The facility will offset approximately 50,000 metric tons of greenhouse gas emissions each year.

Williams also is partnering with energy companies in Washington, Ohio and Texas to transport landfill-produced methane. Like manure, it is a byproduct of waste composition. Capturing methane from dairies and landfills prevents the methane from being released into the atmosphere.

Renewable natural gas is pipeline quality natural gas and is often used for transportation fuels and sometimes called “waste to wheels”.

Methane from the Apex Landfill in New Holland, Ohio, is processed by Montauk Energy before connected to Williams pipeline system.

Scott Hill, Montauk’s vice president of operations, says he values the partnership with Williams and is hoping to expand the project.

“Williams continuing interest and ongoing support of this project has allowed for the beneficial use of RNG, which is equivalent to greenhouse gas emissions avoided by 6.2 wind turbines or reducing CO2 emissions from 3.2 million gallons of gasoline consumed per year.”
