Dominion Energy and Smithfield Foods Inc. are joining forces in a historic initiative to transform the future of sustainable energy and agriculture, announcing their first projects in North Carolina, Virginia and Utah. The companies are forming a joint venture called Align Renewable Natural Gas (Align RNG) that will capture methane emissions from hog farms and convert them into clean, renewable energy for residential home heating and power for local businesses.

“At Smithfield, we recognize true, enduring sustainability initiatives require collaboration with other proven innovators who share a similar vision,” Smithfield president and chief executive officer Kenneth Sullivan said. “Dominion Energy is one such proven innovator, and we are proud to partner with them in our longstanding pursuit of renewable energy. Align RNG is part of our nationwide expansion of Smithfield Renewables -- innovative projects designed to help meet our goal to reduce our greenhouse gas emissions 25% by 2025.”

By capturing methane that would otherwise be released into the atmosphere, the use of renewable natural gas (RNG) leads to a significant reduction in methane emissions from the agriculture and energy industries.

Reducing greenhouse gas emissions

RNG is produced from the methane generated by hog or dairy farms, landfills, wastewater treatment plants and food processing facilities. Capturing the methane from hog farms reduces the use of traditionally sourced natural gas and keeps greenhouse gases from entering the atmosphere. It can be stored and delivered to homes and businesses through the existing natural gas infrastructure, making it a cost-effective, renewable option.

The new joint venture will leverage Smithfield’s relationships with contract farmers who raise and care for its hogs and the decades the company has spent studying and perfecting the commercial viability of "manure-to-energy" projects. Using a technology known as anaerobic digestion, the projects will capture and process methane from large clusters of Smithfield’s company-owned and contract hog farms. Once collected at the farms, the natural gas will then be transported to a central conditioning facility, where it will be converted into RNG.

“Our companies recognize the urgent need to reduce greenhouse gas emissions for the future of our planet. RNG is an innovative and proven way to dramatically reduce greenhouse gas emissions from the agriculture industry by converting it into clean, renewable energy,” said Thomas Farrell II, chairman, president and chief executive officer of Dominion Energy. “RNG is considered carbon negative because it captures significantly more greenhouse gas emissions than are released from its end use in homes and businesses.”

Supporting Virginia, North Carolina initiatives

Virginia Gov. Ralph Northam and North Carolina Gov. Roy Cooper recently announced historic initiatives to significantly lower greenhouse gas emissions in their states over the next decade. RNG will play an important role in supporting these initiatives and help both states achieve their ambitious greenhouse gas reduction targets. Because methane is at least 25 times more potent than carbon dioxide as a greenhouse gas, reducing methane levels can have a more dramatic impact on the environment than other carbon reduction initiatives.

“Across our electric and natural gas fleets, Dominion Energy is becoming a national leader in sustainable energy,” Farrell said. “On the electric side, we are one of only three utilities in the nation to reduce its carbon intensity by more than 40% in the last decade. On the natural gas side, as an industry leader on methane reduction programs, we have already saved more than 10 billion cu. ft. of methane emissions. We have made tremendous progress, but we recognize we need to do more. RNG will build on the progress we’ve made and accelerate our momentum toward a sustainable energy future.”

Bettina Ring, Virginia secretary of agriculture and forestry, said, “This partnership with two leading Virginia-based companies shows the power of Virginia’s largest industry — agriculture — to promote cleaner energy, sustainable family farms and a brighter future for rural communities here in the commonwealth and nationwide.”

Utah Gov. Gary Herbert said he is excited about the technological advances for capturing methane. “That methane, which we call renewable natural gas, can be used to heat our homes, generate low-carbon electricity and drive industry. This bodes well for Utah’s environmental health and economic development.”

Global industry leaders bring resources, expertise, economies of scale

As global leaders in the energy and agriculture industries, Dominion Energy and Smithfield have the resources, expertise and market access to expand this proven technology on a wide scale across the region. The companies are jointly investing at least $250 million in this initiative over the next decade, with initial application on 90% of Smithfield’s finishing spaces in North Carolina and Utah. In addition to these states, projects will be implemented in Virginia and have the potential for wider-scale application across the country.

“With a long-standing commitment to sustainability, and through considerable research and exploration of ways to transform manure into energy for many years, we are well positioned to make unprecedented and revolutionary progress that will positively impact the future of the agriculture and energy industries,” Sullivan said.

Building on the success of Smithfield’s Optima KV pilot project, the new joint venture will immediately expand the program to two larger farm clusters in Duplin and Sampson counties, N.C.; Waverly, Va., and Milford, Utah. Construction of these facilities is expected to begin in late 2018, with the first projects scheduled to be in service in late 2019.

Renewable meets reliable

RNG provides energy 24/7, 365 days a year and can be used on demand to meet the real-time needs of homes, businesses, utilities and manufacturers.

“With this transformational partnership, we are combining the environmental benefits of renewables with the reliability of natural gas to meet the around-the-clock clean energy needs of consumers and businesses,” Farrell said.

RNG will also provide a new revenue stream for family farmers. In fact, the initiative will turn one of farmers’ largest costs into a new revenue source. Farmers who participate in the program will be paid for the energy their farms produce through long-term contracts.

“This project is a true win-win for all involved and reflects Smithfield’s innovative, value-driven approach to sustainability,” Sullivan said.

RNG facilities will also help protect hog farm lagoons from storm-related damage. In addition to converting manure to energy, the covered lagoon digesters mitigate potential issues associated with severe rain events such as hurricanes. Covered lagoon digesters prevent rain from entering the lagoon during severe weather events, providing enhanced environmental protection.
