Navigator cancels US Midwest CCUS pipeline project
Navigator CO2 Ventures LLC has cancelled its 15-million tonne/year (tpy) Heartland Greenway carbon capture, utilization, and sequestration (CCUS) pipeline project, citing “the unpredictable nature of the regulatory and government processes involved, particularly in South Dakota and Iowa.” Heartland Greenway was being developed to collect carbon from Midwest ethanol plants—including 18 operated by POET LLC in Iowa, Nebraska, and South Dakota—for sequestration in Illinois.
The cancellation follows a Sept. 29, 2023, request by Navigator to pause the Iowa permitting process and its Oct. 10, 2023, withdrawal of the 1,300-mile project’s sequestration permit application in Illinois. South Dakota had denied permits for Heartland Greenway earlier in September.
Summit Carbon Solutions LLC and Wolf Carbon Solutions US LLC are still developing multistate projects in the Upper Midwest. The North Dakota Public Service Commission in August 2023 denied a siting permit for Summit’s 18-million tpy Midwest Carbon Express CO2 pipeline, feeling that the company had not taken steps to address outstanding legitimate concerns expressed by landowners (OGJ Online, Sept. 4, 2023).
Summit now expects Midwest Carbon Express to begin operations in 2026 instead of 2024. It is partnering with 34 Midwest ethanol plants in building the 2,000-mile system.
