Bonanza BioEnergy Garden City CCS

The Liberal Kansas carbon capture and storage project integrates CO₂ capture from Conestoga Energy’s Bonanza BioEnergy ethanol facility with dedicated pipeline transport and permanent geologic sequestration. The capture facility currently recovers approximately 150,000 tonnes of CO₂ per year from ethanol fermentation and has been operational since 2012 under an enhanced oil recovery configuration. The project is now transitioning away from EOR toward Class VI dedicated geologic storage, aligning with long term decarbonization and low carbon fuel production objectives. The storage component targets the Arbuckle Formation in southwestern Kansas, a deep saline carbonate reservoir at roughly 5,500 feet depth with favorable porosity, permeability, and thick regional sealing intervals Gary Climate Solutions is leading sequestration development and owns and operates approximately 15 miles of CO₂ pipeline connecting the ethanol plant to the injection site. A feasibility study conducted with SLB modeled 30 years of injection at 150,000 tonnes per year, confirming suitable plume behavior and storage performance for long term containment The project is advancing characterization drilling and permitting activities to support EPA Class VI authorization and transition to permanent geological storage operations.
