by Stephen Groves (Associated Press)  Two companies seeking to build thousands of miles of pipeline across the Midwest are promising the effort will aid rather than hinder the fight against climate change, though some environmental groups remain skeptical.

The pipelines would stretch from North Dakota to Illinois, potentially transforming the Corn Belt into one of the world’s largest corridors for a technology called carbon capture and storage.

Environmental activists and landowners have hindered other proposed pipelines in the region that pump oil, carrying carbon that was buried in the earth to engines or plants where it is burned and emitted. The new projects would essentially do the opposite by capturing carbon dioxide at ethanol refineries and transporting it to sites where it could be buried thousands of feet underground.

Both companies planning the pipelines appear eager to tout their environmental benefits. Their websites feature clear blue skies and images of green fields and describe how the projects could have the same climatic impact as removing millions of cars from the road every year.

However, some conservationists and landowners are already wary of the pipelines’ environmental benefits and safety, raising the chances of another pitched battle as the projects seek construction permits.

The pipelines could fall into a longstanding divide among environmentalists. President Joe Biden and many Republicans are pushing a strategy for tackling climate change that offers a financial boon to industries that use carbon capture and storage to reduce their emissions. But others, such as Greenpeace and Vermont Sen. Bernie Sanders, argue the focus should be completely on developing renewable energy sources and that carbon capture just prolongs dependence on fossil fuels.

Navigator CO2 Ventures, which is planning a pipeline that will stretch over 1,200 miles (1,931 kilometers) through Iowa, South Dakota, Nebraska, Minnesota and Illinois, says it is offering “carbon capture solutions for a greener planet.” While Summit Carbon Solutions, whose pipeline will connect refineries in Iowa, Minnesota, Nebraska and South Dakota to a sequestration site in North Dakota, says it plans to build the world’s largest carbon capture and storage project. Both hope to start some operations by 2024.

…

The federal government set off the scurry of pipeline plans by increasing, by 2026, tax credits to $50 for every metric ton of carbon dioxide a company sequesters. California’s Low Carbon Fuel Standard has sweetened the deal by requiring that distributors in that state buy only ethanol with a low carbon emissions impact; companies that produce such ethanol can get a higher price.

While the practice of storing carbon dioxide in rock formations has been around for almost 50 years, developing technology that captures carbon emissions has proven to be expensive and struggled to gain widespread use.

Ethanol refineries could represent the low-hanging fruit that helps push the technology forward into widespread use. Plants such as corn are natural sponges of carbon dioxide, absorbing the gas and storing carbon as they grow through the spring and summer. When those crops ferment into ethanol, which is eventually mixed with gasoline, it produces a steady, easily-captured stream of carbon dioxide.

Crabtree (Brad Crabtree, Great Plains Institute) said there has not been a single human fatality or serious injury in the United States from transporting or storing captured carbon dioxide. He thinks that as long as companies act responsibly, landowners will be convinced the pipelines are safe and can benefit from them.   READ MORE
