IEP – Post-Combustion CO2 Emissions Control
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 hybrid 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 hybrid sorbent formulations for CO2 capture that have been identified in previous studies.
