CO2 capture technologies: pre-combustion capture

This report provides an update for pre-combustion carbon capture in the power industry. It was developed by the Electric Power Research Institute (EPRI) on behalf of the Global CCS Institute.

Some key points raised in the pre-combustion carbon capture knowledge product are:

  • CO2 removal from coal gasification derived synthesis gas (syngas) is a mature commercial process widely practiced throughout the world.
  • Although there is additional capital involved, the largest component of the poor economic performance in pre-combustion capture systems is the loss of energy involved.
  • Much of the RD&D effort is aimed at reducing the energy losses due to capture in the various process steps but one of the greatest improvements to the overall IGCC technology is the development of high firing temperature larger gas turbines of higher efficiency.
  • The next key event for the advance of pre-combustion capture technology will be the integrated operation of the first IGCC plant with capture at the Kemper County IGCC plant in Mississippi in 2014.
  • EPRI and the US Department Of Energy have identified a roadmap of IGCC technology developments that can potentially improve the IGCC efficiency to a level that matches or exceeds that of the current IGCC technology without capture.
  • With IGCC there are multiple pathways of improvements using different gasification technologies which may find particular application more favourably in certain climate conditions, locations and coal types.
