The objective of the CarbonSAFE Northern Michigan Basin project (Department of Energy Award Number DE-FE0029276) was to take the first step in developing an integrated commercial geologic CO2 storage complex in the Northern Michigan Basin through the Phase I pre-feasibility study. This includes demonstrating that the storage sites within the complex have the potential to store more than 50 million metric tons (MMT) of industrially sourced CO2 emissions safely, permanently and economically. A high-level sub-basinal evaluation focused on assessing the lateral extent, thickness, structure, properties, and CO2 storage capacity for two saline reservoirs: the St. Peter sandstone and Bass Islands dolomite. Additionally, a catalog of Niagaran reefs was used in collaboration with the regional characterization work completed by the MRCSP to identify top targets for CO2-EOR. This study also included an evaluation of risks and identification of land usage. All the collected and interpreted data was integrated with CO2 source locations to identify potential regions for commercial-scale carbon capture and storage (CCS). The modeling analysis demonstrated 50 MMT of CO2 could be injected into the St. Peter Sandstone and that 82 reefs were needed to reach a goal of a combined commercial storage volume. Lastly, the project successfully formed a CCS coordinate team which consisted of industry partners, geoscience experts, legal and regulatory experts, outreach coordinators, and financial analysis experts. The team consisted of all critical expertise needed to develop a commercial CCS project in the region.
