ABSTRACT:
Many parts of the country have no potential geological reservoirs in the appropriate depth range for sequestration of CO2 from coal-fired power plants. Within a significant fraction of the limited areas where reservoir rocks may be in the appropriate depth range, defining localized potential traps (if any) will represent an enormous challenge. Those traps already reasonably defined as oil & gas plays likely include numerous penetrations (old wells and test holes) that could leak CO2 at the storage pressures required for sequestration can be highly toxic. Most sequestration endeavors for the volumes required would require well fields (and surface piping) covering hundreds or thousands of square miles per power plant. |
