Lorain CCS

The Lorain County Landfill CCS Project, proposed by Lorain Carbon Zero Solutions, LLC (a subsidiary of Republic Services), is a Class VI CO₂ sequestration project located in Oberlin, Ohio. The project plans for one injection well (CCS #1) drilled with a 1,200-meter lateral into the Mt. Simon Sandstone, a Cambrian-aged formation with favorable porosity and permeability for CO₂ storage. The overlying Rome and Conasauga Formations provide the primary confining zones, with additional protection from the thin Kerbel Formation and the regionally extensive Knox Dolomite. The project is designed to inject up to 387 metric tons of CO₂ per day (approximately 141,000 tons per year) under pressure conditions not exceeding 90% of fracture pressure. Monitoring includes two dedicated wells: one at the base of the USDW and another above the confining zone updip of the injection toe. A robust testing program will continuously track pressure, temperature, plume migration, corrosion, groundwater chemistry, and annulus integrity using fiber-optic DTS, pressure transducers, and corrosion coupons. Over its operational life, the site is expected to safely store over 1 million metric tons of CO₂, followed by post-injection site care and long-term monitoring to ensure containment integrity.
