Carbon Sequestration and IGCC: Partnership Technologies

Herzog, Howard (Massachusetts Institute of Technology)

Clean-Energy.us Summary

PowerPoint on CO2 issues as linked to IGCC. Herzog, the principal research engineer at MIT's Laboratory for Energy and Environment, provides an outline of current CO2 use in enhanced oil recovery and natural gas injection. Concludes that it is possible to successfully store massive quantities of CO2 through geological sequestration, saying that the main hurdle is "primarily an increase in scale -- both by volume and time horizon.
