The first large-scale CCS demonstration project, Sleipner, started up in 1996. Over the next two decades, more than a dozen other CCS demonstration projects came on-line. However, there were many more projects that were announced that never came to fruition. By studying both the successful and unsuccessful projects, one can discern patterns and learn valuable lessons that can be applied to future efforts. This presentation summarizes a study that analyzes the financing of large-scale CCS demonstration projects and reports the lessons learned.
