Biorefining company Green Plains Inc. has started construction of compression infrastructure for its carbon capture and storage (CCS) project in Nebraska, the company said in a news release March 17.
The project, expected to start up in second-half 2025, will enable the permanent sequestration of about 800,000 tons of biogenic CO2 each year from Green Plains’ three Nebraska facilities in Central City, Wood River and York, according to the release.
“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,” said Chris Osowski, executive vice president of operations and technology, at Green Plains.
The infrastructure is part of the Tallgrass Trailblazer project to convert a natural gas pipeline to transport CO2 from ethanol plants to sequestration sites.
Green Plains also announced it is temporarily idling operations at its Clean Sugar Technology facility in Shenandoah, Iowa, as it “focuses on optimizing its product mix to maximize current returns.”
The company said the facility has already proven it can produce high-purity dextrose with a lower carbon intensity.
“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.”
