Key Points: Sally Benson

Why is Carbon Capture and Sequestration (CCS) important?

  • Fossil fuels will continue to be the major source of energy for the foreseeable future
  • Without CCs it will be difficult to meet emissions reduction targets of 50% to 80% by 2050

How much sequestration capacity is available?

  • Estimates indicate sufficient capacity for sequestering emissions for over the next century
  • Experience and research will improve reliability

Will it lead back to the atmosphere and how will we know?

  • Seals providing a permeability and capillary barrier can retain buoyant fluids for geologic time scales
  • Careful site selection and operations with regulatory oversight
  • Many monitoring methods are available – with more to come
