Heartland Greenway is a Navigator CO₂ proposed carbon capture, utilization, and storage (CCUS) system that will provide biofuel producers and other industrial customers in five Midwest states with a long-term and cost-effective means to reduce their carbon footprint. Heartland Greenway will reach industrial customers in Illinois, Iowa, Minnesota, Nebraska and South Dakota. Operations are expected to be phased in early 2025.

The multi-faceted project will help customers finance and construct their carbon dioxide (CO₂) capture equipment; and safely transport the captured CO₂ over a newly built 1,300-mile pipeline network to either: injection wells for permanent, geological storage, or terminal off-takes for commercial use.

Once fully expanded, Heartland Greenway will have the ability to capture and store 15 million metric tons of CO2 every year.
