Hoosier #1

The Hoosier #1 Project is a Class VI CO₂ sequestration initiative proposed by One Carbon Partnership, LP, a joint venture between Vault 44.01 and Cardinal Ethanol. Located at Cardinal Ethanol’s plant in Randolph County, Indiana, the project is designed to capture and permanently store CO₂ generated from ethanol fermentation. Cardinal produces about 420,000–450,000 metric tons of CO₂ per year, and the project aims to capture and inject this full volume. Captured CO₂ will be compressed, purified, and transported to a dedicated injection well (CCS1) for storage in the Mt. Simon Sandstone, with the Eau Claire Shale as the primary confining layer and the Knox Dolomite as a secondary confining zone. Over a planned operating life of 12 to 30 years, the project anticipates storing between 5.4 and 13.5 million metric tons (MMT) of CO₂. The facility will include multiple wells for injection and monitoring, supported by seismic surveys, geomechanical modeling, and a 3D seismic program to ensure storage integrity.
