Green Plains Breaks Ground on Carbon Capture Compression Equipment in ‘Advantage Nebraska’ Strategy, Provides Update on Clean Sugar Technology™

OMAHA, Neb.--Green Plains Inc. (NASDAQ:GPRE) today announced that construction has commenced on the compression infrastructure for its carbon capture and storage initiative in Nebraska, an important step in the company’s ongoing transformation to produce low-carbon, high-value biofuels and ingredients.

The compression equipment will enable the permanent sequestration of approximately 800,000 tons of biogenic carbon dioxide each year from Green Plains’ three Nebraska facilities in Central City, Wood River, and York, keeping the project on track for start-up in the second half of 2025.

"Breaking ground at our sites for this project is another milestone in executing our ongoing ‘Advantage Nebraska’ strategy," said Chris Osowski, Executive Vice President of Operations and Technology. "With construction of the laterals for the Trailblazer CCS project underway and now with compression equipment beginning to be installed, we are positioned to be an early mover in sequestering biogenic CO2, unlocking significant value for our shareholders."

Green Plains also announced that it will temporarily idle operations at its Clean Sugar Technology (CST™) facility in Shenandoah, Iowa, as the company focuses on optimizing its product mix to maximize current returns. CST™ has already proven its ability to produce a high-purity dextrose with a lower carbon intensity, and the company remains confident in its commercial potential. The decision to temporarily pause operations presents an opportunity for Green Plains to further refine the dextrose production process while continuing to build significant commercial interest.

"The innovative Clean Sugar Technology is proven, and customer interest remains strong," added Osowski. "As we refine our commercialization strategy, we are focused on optimizing plant performance to ensure CST becomes a cornerstone of our long-term value creation strategy."
