Evaluation of CO2 Capture from Existing Coal-Fired Plants by Hybrid Sorption Using Solid Sorbents (CACHYS™)
Project No.: DE-FE0007603

The University of North Dakota (UND) is scaling up and demonstrating a solid sorbent technology for carbon dioxide (CO2) capture and separation from coal combustion-derived flue gas.  The technology – Capture from Existing Coal-Fired Plants by Hybrid Sorption Using Solid Sorbents Capture (CACHYS™) – is a novel solid sorbent process based on the following principals:

  • Reduction of energy for sorbent regeneration.
  • Utilization of novel process chemistry.
  • Contactor conditions that minimize sorbent-CO2 heat of reaction and promote fast CO2 capture.
  • Low-cost method of heat management.

Another key component of the technology is the use of a low-cost sorbent (consisting of active component, promoter, and support).  UND is evaluating effective and cost-competitive sorbent formulations for CO2capture that have been identified in previous studies.
