Midwest CO₂ Pipeline Abandons Climate Goals to Boost Oil Production

A long-delayed pipeline project in the Midwest has taken a sharp turn in direction. Originally designed to store carbon dioxide underground, the scheme will now help extract more oil from ageing wells. The shift comes after years of legal battles and regulatory setbacks for Summit Carbon Solutions, the company behind the plan.

The change also brings a new financial incentive—up to $1.5 billion a year in potential tax credits for the ethanol plants supplying the CO₂. In 2021, Summit Carbon Solutions proposed a 2,000-mile pipeline to transport liquified CO₂ from ethanol plants in Iowa to underground storage sites in North Dakota. The company, led by Iowa businessman Bruce Rastetter, argued the project would slash greenhouse gas emissions while supporting the Midwest's farm economy. At the time, its website emphasised sustainability, calling the pipeline a key step toward lower-carbon aviation fuel.

Legal and political hurdles soon piled up. South Dakota banned the use of eminent domain for carbon pipelines in 2025, blocking a crucial section of the route. Then, in February 2025, a North Dakota judge revoked Summit's permit to store CO₂ underground. Meanwhile, disputes over land rights stalled progress in state legislatures across the region.

Facing these roadblocks, Summit has now abandoned its original climate-focused pitch. The company scrubbed mentions of 'climate change' and 'global warming' from its website. Instead, it will redirect the captured CO₂ toward enhanced oil recovery (EOR)—a process that pumps the gas into wells to squeeze out more crude. The pipeline, once framed as a green solution, is now billed as a vital supply line for America's oil and gas industry.

With 25 ethanol facilities under contract, Summit stands to gain billions in tax credits annually. The financial upside comes as the project's environmental goals fade into the background. The pipeline's new purpose marks a clear departure from its initial promise of cutting emissions. Instead of storing CO₂, the gas will be used to boost oil production in depleted fields. The shift follows four years of regulatory battles, with no recent policy changes cited as the reason for the change in strategy.

The company now positions itself as a key supplier to the fossil fuel sector, leaving its earlier climate commitments behind.
