Proposed carbon pipeline will miss some ethanol plant emissions

Proposed carbon pipeline will miss some ethanol plant emissions

The planned $8 billion carbon pipeline in South Dakota promises to capture CO2 from ethanol fermentation but will leave emissions from fossil-fuel-powered equipment untouched.

Joshua Haiar reports for South Dakota Searchlight.

In short:

  • The pipeline aims to capture up to 18 million metric tons of CO2 from ethanol fermentation annually, but leaves 7 million tons from machinery emissions.
  • CO2 from gas-powered equipment is harder to capture and more expensive due to its mixed composition.
  • A report suggests ethanol production could achieve net-negative emissions by 2040 through carbon capture and other sustainability efforts.

Key quote:

"This is both a giant pipeline project and a drop in the bucket."

— Daniel Sanchez, assistant professor at the University of California-Berkeley’s Department of Environmental Science, Policy and Management

Why this matters:

Capturing only fermentation emissions limits the pipeline's environmental impact. Broader efforts are needed, including reducing natural gas use at ethanol plants, to meaningfully cut greenhouse gases.
