The federal government has awarded a total of about $67m over four years for these projects, which aim to reduce the energy and cost penalties of advanced carbon capture systems applied to coal-fired power plants.

The selections focus on slipstream-scale development (0.5 to 5MWe) and testing of advanced solvent-based post-combustion CO2 capture technologies, DOE said.

According to DOE, the overall goal of the research is to develop CO2 capture and separation technologies that can achieve at least 90% CO2 removal at no more than a 35% increase in the cost of electricity.

Neumann Systems Group, Linde, Southern Company and University of Kentucky Research Foundation are receiving the federal funding for the carbon capture projects which are managed by the Office of Fossil Energy’s National Energy Technology Laboratory.
