The CAER project -- Advancing Post-Combustion CO2 Capture through Increased Mass Transfer and Lower Degradation -- aims to "significantly advance deployment of CO2 capture through enabling technologies that increase CO2 mass transfer and reduce solvent loss."
The project will involve the development and fabrication of customized dynamic packing to increase CO2 mass transfer in the absorber column, and an electro-chemical cell to adsorb and decompose nitrosamines before they can be emitted into the environment. After both of these systems have been constructed, they will be tested on CAER's bench-scale CO2 capture unit.

UK CAER's current 0.7 mw small pilot CO2 capture facility that operates at Kentucky Utilities' E.W. Brown Generating Station in Burgin, Kentucky, has led to scientific and engineering breakthroughs in the field, according to the CAER. The post-combustion system features modular equipment and free-standing columns with built-in advanced controls to continually minimize the CO2 capture energy penalty while responding to a dynamic external demand. The new system will combine several facets to simultaneously address capital cost, energy consumption, load change and environmental impact.
Project collaborators include LG&E and Kentucky Utilities, Carbon Clean Solutions, University of Texas at Austin, Membrane Technology Research, Electric Power Research Institute, Huaneng Clean Energy Research Institute, Koch Modular Process Systems, Worley Parsons and Smith Management Group.

This FOA will address the cost and operational challenges associated with current CO2 capture technologies that are commercially available for industry, providing for additional development to these technologies at coal-fired power plants. Some of the challenges that will be addressed include a need to improve the reliability and operational flexibility; reduce high capital costs; and reduce the high-energy penalty associated with operating existing technology.
The National Energy Technology Laboratory (NETL) will manage the selected projects, which will concentrate on transformational technologies focused on: developing transformational materials and processes for CO2 capture that will enable step-change reductions in the capital and energy cost; and enabling technologies that facilitate improved performance of transformational CO2 capture processes to reduce capital cost and energy penalties, and improve operational reliability and flexibility.
