Navigator carbon capture pipeline project, which includes POET ethanol plants, files for permit in Iowa

Navigator CO2 Ventures on Tuesday, Oct. 25, 2022, filed the application for the Heartland Greenway project with the Iowa Utilities Board. Other states on the route are South Dakota, Minnesota, Nebraska and Illinois, with a site in Illinois designated for storing the liquid carbon dioxide. South Dakota-based POET has 18 ethanol plants included in the project.

DES MOINES, Iowa — Navigator CO2 Ventures, the developer of a multi-state carbon capture project that includes ethanol plants operated by POET, has filed for a permit in Iowa.

The Tuesday, Oct. 25, filing with the Iowa Utilities Board for the Heartland Greenway project is Docket No. HLP-2021-0003 .

Most of the ethanol plants on Navigator's Heartland Greenway route are in Iowa, but it also includes five ethanol plants in South Dakota, one in Minnesota, three in Nebraska and one in Illinois. At least some of the carbon captured from the ethanol plants will be stored underground in Illinois.

Navigator is developing the Heartland Greenway to provide ethanol producers and other industries a way to reduce their carbon footprint, taking advantage of federal tax credits that encourage capturing and storing greenhouse gases.

"With the submission of the IUB permit, Navigator is pleased to continue making notable progress in the development of the Heartland Greenway, which will be one of the premier carbon management platforms in the United States. We are continuing to work with landowners, community leaders, and other key stakeholders across the project footprint," Navigator said in an emailed statement.


Carbon capture pipelines are being met with some landowner resistance in the Midwest, with landowners concerned about damage to farmland, property values and the safety of the hazardous liquid pipelines.

Navigator, which has its headquarters in Omaha, Nebraska, made its filing with the South Dakota Public Utilities Commission on Sept. 27

Navigator has public hearings coming up on the project in South Dakota: 5:30 p.m., Nov. 21 in Canton; 11:30 a.m., Nov. 22 in Flandreau; and 5:30 p.m., Nov. 22 in Sioux Falls.

In Iowa, public hearings are held before the permit application is filed; the Navigator meetings were in August and September.

POET, based in Sioux Falls, South Dakota, announced in June that the project would include 18 of its bioprocessing facilities. POET is the world's largest producer of biofuels.

The June announcement said the project is on schedule to be operating in 2025. It is designed to deliver up to 15 million tons of carbon dioxide annually to multiple storage sites.

Valero and BlackRock Global Energy and Power are other key partners in the Navigator project.

In Minnesota, the pipeline will go through Martin County on the state’s southern border, connecting the Valero ethanol plant in the town of Welcome.


Navigator's Heartland Greenway is one of three carbon capture projects involving the ethanol industry in Iowa, the other being the five-state Summit Carbon Solutions project and the Wolf Carbon Solutions project that includes ethanol plants owned by ADM.
