The Vervain Project is part of the Heartland Greenway proposed carbon capture, utilization, and sequestration (CCUS) system. The system is planned to connect industrial customers in Illinois, Iowa, Minnesota, Nebraska, and South Dakota through a 1,300-mile pipeline network and permanently sequester up to 15 million tonnes per annum (Mtpa) of carbon dioxide (CO2) into sequestration sites in central Illinois. The Heartland Greenway system is proposed by Navigator CO2 Ventures (NCV) and will be operated by Heartland Greenway Carbon Storage, LLC (HGCS), a subsidiary of NCV. Operations will be phased with an expected start date in early 2025.

The Vervain Project is one of several sites in Central Illinois that is being developed by NCV for long-term sequestration into the Mt. Simon Sandstone. The project seeks to transport 2.5 Mtpa to a location in the southwest corner of McLean County, Illinois. Well construction is expected to commence in Q1 2024. Injection will commence following completion and approval of all UIC Class VI permit requirements.
