Decarbonising fertiliser production in Iowa via CCS

Navigator will provide carbon transport and storage services to decarbonise OCI’s Iowa Fertilizer Company plant via the newly-announced Heartland Greenway CCS system. In the first phase, 500,000 tonnes of carbon dioxide will be captured from process gas at the plant beginning in 2024, scaling up to 1.13 million tonnes. This equates to production of 300,000 and 700,000 tonnes of blue ammonia respectively. 45Q tax credits from the US federal government will make the near-total decarbonisation of Iowa Fertilizer Company economically feasible.

“We are monitoring the on-going discussions in Congress around enhancements to the 45Q program to support the project economics and potentially open the opportunity to widen the scope of this project to capture more CO₂. This agreement follows the announcement earlier this year that we have the ability to produce up to 365,000 metric tons per year of blue ammonia at OCI Beaumont in Texas, and blue and green ammonia projects in Abu Dhabi and Egypt, and marks another milestone towards achieving our sustainability goals and progressing towards a greener future.”

Heartland Greenway

Navigator’s proposed pipeline system will cover 1,200 miles and connect five Midwest states with a sequestration site in southwest Illinois (the Mt Simon formation). An additional pipeline is being proposed by Summit Carbon Solutions, covering an additional 2,000 miles and reaching further into the Dakotas. The Des Moines Register reports that Navigator has reached agreements with 20 ethanol and fertilizer plants for capture, transport & sequestration services (Summit is aiming to sequester carbon from 31 biodiesel plants).
