NW Natural, BioCarbN partner on RNG projects

NW Natural is partnering with BioCarbN, a developer and operator of sustainable infrastructure projects, to convert methane from Tyson Foods facilities into RNG.

Under this partnership, NW Natural, a subsidiary of NW Natural Holding Company, has options to invest up to an estimated $38 million in four separate RNG development projects that will access biogas derived from water treatment at Tyson Foods’ processing plants.

Tyson Foods is a US multinational firm based in Arkansas that operates in the food industry. It is a major processor and marketer of chicken, beef, and pork.

In December, NW Natural exercised its option for the first development project in Nebraska, initiating investment in an estimated $8 million project. Construction is expected to begin in early 2021, with completion and commissioning expected in late 2021.

Once fully operational, these four projects are expected to generate more than 1.2 million MMBtu of RNG annually – enough to provide heat for around 18,000 homes NW Natural serves in Oregon.

This is the firm’s first investment under the landmark new state RNG law, Oregon Senate Bill 98, which supports renewable energy procurement and investment by natural gas utilities.

David H Anderson, NW Natural president and CEO, said: “Our vision is to champion innovative policies and new technologies to provide a substantial climate benefit for our customers.

“We have a long history of being leaders on environmental stewardship and climate change. This partnership is just one step forward in what we intend to be many to follow, as we work to source more and more of our supply from renewables over time.”

Partners for the projects include BioCarbN, based in Idaho, and Cross River Infrastructure Partners, a Connecticut-based developer of waste-based infrastructure projects.

The BioCarbN projects will be separate from the three previously announced RNG projects that NW Natural is currently interconnecting to its system. These include the City of Portland’s Bureau of Environmental Services’ Columbia Boulevard Wastewater Treatment Plant; the Eugene-Springfield Water Pollution Control Facility; and the Shell New Energies Junction City biomethane facility.
