Tri-State Redbud 2

The Tri-State CCS Redbud 2 Project, developed by Tri-State CCS, LLC (a Tenaska affiliate), is a proposed Class VI carbon storage project located in Marshall County, West Virginia, within the broader Tri-State CCS Hub spanning Ohio, Pennsylvania, and West Virginia. The project includes four planned CO₂ injection wells (TR2-1 through TR2-4) targeting deep saline formations in the Appalachian Basin, specifically the Lockport Dolomite (LIC) and Medina Sandstone (MIC) injection complexes, at depths of approximately 8,600–8,900 feet. The facility is designed for simultaneous injection into both zones, with modeled average injection rates of approximately 0.22–0.26 million tonnes per year per well (combining LIC and MIC). This equates to roughly ~0.9–1.0 million tonnes per year across the site under expected operating conditions. The project is engineered with a maximum design capacity of up to ~1.0 million tonnes per year per well (0.5 MMt/y per zone), or ~4.0 million tonnes per year across all wells, subject to pressure and reservoir constraints. Injection is expected to begin around 2028 and continue for approximately 30 years, followed by a 50-year post-injection monitoring period. Under modeled conditions, the project is expected to store approximately ~25–30 million tonnes of CO₂, with additional upside under maximum capacity scenarios.
