Renewable Natural Gas
Dominion Energy is rapidly expanding the use of renewables like solar, wind and hydropower. But did you know that renewable energy can also come from farms, food waste and landfills?
That’s right. Thanks to technological innovation, we can capture waste methane from farms and other sources and convert it into clean energy that can heat homes and power businesses.
It’s called renewable natural gas, or RNG, and it’s transforming the future of clean energy. When methane is converted into RNG, it captures 25 times more greenhouse gases from the atmosphere than are released when RNG is used by consumers. That makes RNG better than zero-carbon. It’s actually carbon-beneficial!
Partnering to Reduce Greenhouse Gas Emissions
We’re teaming up with the largest U.S. pork and dairy producers to expand renewable natural gas projects across the country and deliver it to U.S. consumers. We’re jointly investing $500 million with Smithfield Foods to produce RNG from U.S. hog farms, and through our partnership with Vanguard Renewables, we’re investing an additional $200 million to develop dairy RNG projects across the U.S. When combined, these partnerships will reduce the same amount of greenhouse gas emissions as taking 650,000 cars off the road or planting 50 million new trees each year.
We’re also purchasing RNG from a number of waste facilities across the country, including the South Davis Water District and Bayview Landfill in Utah, the American Landfill in Ohio, and the Upper Piedmont Landfill in North Carolina. Our goal is to meet 4 percent of our gas utility customers’ needs with RNG by 2040. Because RNG captures 25 times more greenhouse gas than it releases, that will offset our customers’ carbon footprint by 100 percent!
Where does RNG come from?
When animal waste and other organic material breaks down, it produces methane, or natural gas. Converting it into renewable natural gas is simpler than you might think.
