CO2 transport is important to simplify and optimize CCUS and provide storage options for sources in areas where storage options are limited; however, pipeline transport is not always the best option for transport. The paper presents the optimization and design of an intermodal transport hub in the Central Appalachian Basin Region of the United States (eastern Ohio, western Pennsylvania. and northern West Virginia). The paper presents the conceptual design of an intermodal transport system that serves natural gas related sources of various sizes in the region and is adapted for additional hydrogen sources that may come online as the Appalachian Regional Clean Hydrogen Hub (ARCH2) project progresses. This work demonstrates the optimization of these networks, including the selection of the modes of transport, operational conditions, permitting and acquisition of rights-of-way, and a technoeconomic assessment (TEA) and business case analysis (BCA). The work also focuses on a specific node within the optimized transport network. This node was selected as the location of a pre-Front Engineering and Design (Pre-FEED) location and is used to demonstrate the potential flow assurance, land and permitting requirements, and site conditions. The paper concludes with a regional assessment, showing the potential for hub expansion, and a hazardous identification analysis. results of this study demonstrate that it is technically feasible to create an intermodal carbon sequestration hub and serves as a framework to show how we may decarbonize smaller sources of CO2 emissions where a pipeline is not feasible.
