Ethanol Plant CCS Feasibility Study and Strategic Recommendations
In 2025, Sproule ERCE evaluated the potential for carbon capture and storage (CCS) near a client’s facility in the midwestern United States. The study examined geological suitability, reservoir quality, environmental risks, seismic activity, and regulatory considerations. Analysis of extensive geological and geophysical data identified potential storage zones but revealed poor reservoir conditions and significant operational risks. We recommended against immediate CCS development and advised exploring partnerships with established CO₂ transport and storage operators as a more strategic and lower-risk path forward.

Project Highlights
- Comprehensive assessment of geological formations for CCS potential
- Identification of operational and regulatory barriers limiting project viability
- Cost estimation for advanced data acquisition and risk analysis phases
- Strategic recommendation to partner with CO2 pipeline operators for market entry
Challenges:
Geological Limitations Surfaced: Local deep rift clastic and volcanic formations have low permeability and poor reservoir quality, making CO₂ injection ineffective. Faults and fractures raise leakage risk despite generally low seismic activity. These subsurface conditions present strong technical barriers to CCS development.
Regulatory and Environmental Hurdles: Freshwater aquifers protected by EPA salinity rules and numerous water wells complicate operations. Compliance requirements and groundwater protection add regulatory complexity, limiting injection options and raising legal risks.
High Investment and Uncertainty: Further CCS assessment would require costly 2D seismic, gravity, and magnetic surveys, with timelines from six months to years and uncertain returns. Balancing cost, technical challenges, and regulatory risks hinders project justification.

Solutions:
Focused Data-driven Approach: Sproule ERCE began with thorough screening using existing geological and geophysical data to identify CCS viability. Our tailored reports evaluated reservoir quality, seal integrity, and environmental risks in detail. Collaboration with Client ensured alignment with their operational goals and compliance needs.
Strategic Partnership Recommendations: Recognizing local limitations, we advised exploring relationships with established CO2 pipeline and storage operators. This approach reduces capital exposure and accelerates participation in regional CCS markets. We emphasized careful due diligence and ongoing industry collaboration as critical success factors.
Phased Investment Plan: We proposed steps for additional data acquisition and risk analysis with cost and timeline estimates, enabling Client to validate CCS potential before committing major resources.
