What is Align RNG?

Align RNG is a joint venture between Dominion Energy and Smithfield Foods that is capturing methane from our nation’s hog farms and turning it into clean energy for consumers. It's called renewable natural gas, or RNG, and it's transforming the future of clean energy and sustainable agriculture.

How Does it Work?

Capturing methane from the farm
Capturing Methane from the Farm

As hog manure breaks down, it produces methane gas. Instead of allowing methane to enter the atmosphere, it’s captured in an anaerobic digester.

The methane captured from multiple farms is sent to a central conditioning facility, where it is refined to 99% pure methane, the same as traditional natural gas.

The RNG is then put into an existing distribution system to serve homes, businesses, power plants and other natural gas consumers.
