Resource Insights: Geology beats technology: Shell shuts down oil shale pilot project: "A clue comes from one sentence in coverage in The Denver Post: "Full-scale production would probably have required building a dedicated power plant." In simple terms, it takes energy to get energy. Shell's process requires copious amounts of electricity to heat the rock in place through boreholes in order to release the waxy hydrocarbons embedded in it. In this pilot project, the subterranean rock was heated for three years before liquids were captured and brought to the surface for further processing."
