Workshop on Technology Pathways Forward for Carbon Capture & Storage on Natural Gas Power Systems

This workshop explores the possibilities and challenges of CCS on natural gas power systems, including storage and recycling of CO2 for EOR. It also addresses the legal, water, and liability issues associated with sequestration. The workshop includes case studies and cost comparisons for CCS on coal and gas-fired EGUs.

  1. Workshop on Technology Pathways Forward for Carbon Capture & Storage on Natural Gas Power Systems United States Energy Association Theresa Pugh April 22, 2014

  2. Coal Plant Retirement Estimates as of Fall 2013 Sources: SNL; industry news; corporate announcements Notes: † 59 GWs “ripe for retirement” in addition to estimated 41 GWs announced; *includes ~9 GWs retired in 2012 Graphic used with permission from Scott Madden

  3. CCS Adequately Demonstrated?

  4. More to CCS Than Separation Technology http://www.publicpower.org/files/HTM/ccs.html

  5. Storage and recycling of CO2 for  EOR and sequestering from power plants under CCS are similar but not at all the same.

  6. Sequestration requires addressing many unknowns including: • Laws to separate mineral rights vs. surface rights in most states • Address western water law-- drilling is depth limited and first in right issues • CERCLA • RCRCA • UIC system does not address other water and liability issues • Products liabilities laws • Trespass laws 

  7. Map of Existing CO2 Pipelines http://naruc.org/Grants/Documents/Final-ICF-Project-Report071213.pdf

  8. Map of Possible CO2 Pipeline Corridors for a High CCS Case with Greater Use of EOR http://naruc.org/Grants/Documents/Final-ICF-Project-Report071213.pdf

  9. Holland Board of Public Works(a case study about natural gas combined cycle and a BACT analysis for CCS in 2013) • CCS for NGCC CHP Plant  is theoretical as it has not been adequately demonstrated and did not meet 5 part Top Down BACT test • Capital cost of $183 million for  geologic sequestration for the proposed 114 MW plant nearly equates to the cost of the NGCC plants without CCS • Inclusion of $37 million ANNUALLY in operating costs for geologic sequestration would exceed expected revenues without significant rate increases to customers

  10. Holland Board of Public Works(a case study about natural gas combined cycle and a BACT analysis for CCS in 2013) • CO2 from NGCC is only 1/4 the concentration of coal fired power plant and not easily captured  • CCS on a NGCC with higher renewables makes the operation too complex • No large scale CCS has been demonstrated in Midwest Regional Carbon Sequestration Partnership region and that process  in Northern Niagara Pinnacle Reef is expected to not be finished until 2015 • Water usage for separation and sequestration

  11. Comparison of CCS Cost for Coal and Gas-fired EGUs

  12. Comparison of 90% CCS Cost for Coal and Gas-fired EGUs

  13. Comparison of 90% CCS Cost for Coal and Gas-fired EGUs(550 MW nominal net)
