CCS Adequately Demonstrated?

More to CCS Than Separation Technology
http://www.publicpower.org/files/HTM/ccs.html
Storage and recycling of CO2
for EOR and sequestering from
power plants under CCS are similar
but not at all the same.

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

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
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
