Detailed Description

Is Sequestration Necessary? Can We Do It at an Acceptable Total Cost?

By Yousif Kharaka, USGS National Research Program

 

  • Combustion of fossil fuels currently releases approximately 30 billion tons of carbon dioxide (CO2) to the atmosphere annually
  • Increased anthropogenic emissions have dramatically raised atmospheric CO2 concentrations in the last 100 years
  • There is broad scientific consensus that global warming, and resulting climate changes, are caused mainly by increases in atmospheric CO2
  • Geochemistry of CO2 sequestration: Recent results and remaining major technical and environmental challenges for successful geologic storage
