How can the cost gap between IGCC plants and pulverized coal plants be closed?
The Capture-Committed Power Plant
Moving coal forward requires a clear path to CCS.
in a carbon-constrained future. To ensure this power generation doesn’t contribute to climate change, a bridge must be built over the gap between the current plants built without CCS and future plants that will be built from the start with CCS. Capture-ready plants have been proposed as that bridge, but that approach gives assurance that many deem inadequate that CCS will actually be implemented. Capture-committed plants can provide that needed assurance, and get the coal-fired power industry moving toward sustainable future.

This concept is similar to a proposal that has been made for “capture options” for coal-fired power plants in China, but has the advantage over that proposal of ensuring the availability of financing of CCS and its implementation by a specified date.

13. The Carbon Sequestration Leadership Forum (CSLF) Technical Group has developed procedures for estimating storage capacity. The CSLF is an international initiative focused on the development of CCS. The governments of 21 countries and the European Commission are members of the CSLF. Information about these capacity storage estimation procedures can be found on the CSLF website. See the documents of the Task Force for Review and Identification of Standards for CO 2 Storage Capacity Estimation at http://www.cslforum.org/taskforces.htm.
