SimCCS supports decision making by integrating applications in operations research, geographical information systems, carbon capture engineering, pipeline infrastructure design and geologic reservoir performance. Users are able to produce integrated CCUS system designs for problems ranging from single facilities to large, regional networks involving multiple carbon emission sources and geologic sinks. By harnessing the power of high-performance computing resources, users can investigate how CCUS may play a meaningful, cost-competitive role in mitigating carbon emissions.
