Vol 1 Chapter 38: Capture and Separation Technology Gaps and Priority Research Needs
Helen R. Kerr
Abstract: This final chapter summarizes the major conclusions and results of the CCP’s capture and separation technology development projects. It provides a look forward to Phase II of the CCP and future research needs. Separation technology challenges include:
- A fundamentally different approach to post-combustion capture. The CCP saw some potential for novel integrated approaches for separation with advanced solvents.
- Pre-combustion decarbonization to make hydrogen at very large scale as a precursor to a hydrogen-based combustion system. A systems analysis and comprehensive approach to the major components of a hydrogen fuel system are needed.
- Oxygen-fired combustion. Combustion in either oxygen-enriched air or pure oxygen offers the advantage of reduced NOx and SOx emissions while producing a highly concentrated CO2 stream for sequestration. Oxygen production is a major need and challenge – at the needed scale and costs. Chemical looping combustion that combines oxygen production with combustion may have great promise. It needs comprehensive study to determine its future potential. Public policy, incentives and regulatory activities by the various governments will be a substantial
challenge for those attempting to sequester CO2. Worldwide governmental actions must be monitored and
accounted for in future technical developments.
