DOE to award $37M to four projects for carbon capture from coal power plants; targeting 90% removal with 35% max increase in electricity cost

15 August 2011

The US Department of Energy’s (DOE) Office of Fossil Energy (FE) has selected four projects aimed at reducing the energy and cost penalties of advanced carbon capture systems applied to power plants for further development.

Valued at approximately $67 million (including $15 million in non-federal cost sharing) over four years, 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. This would represent a significant improvement over projected increases in electricity costs using existing technologies.

Existing carbon capture systems currently require large amounts of energy for their operation, resulting in decreased efficiency and reduced net power output when compared to plants without carbon capture, utilization, and storage (CCUS) technology. These penalties can add as much as 80’ to the cost of electricity for a new pulverized coal plant.

The four projects focus on slipstream-scale development (0.5 to 5 MWe) and testing of advanced solvent-based post-combustion CO2 capture technologies. Post-combustion capture offers great near-term potential for reducing power sector CO2 emissions because it can be added to existing plants.

The projects, managed by FE’s National Energy Technology Laboratory include:

  • Linde LLC: Slipstream Pilot Scale Demonstration of a Novel Amine-Based Post-Combustion Process Technology for CO2 Capture from Coal-Fired Power Plant Flue Gas. The proposed project will use a post combustion capture technology incorporating BASF’s novel amine-based process at a 1 MWe equivalent slipstream pilot plant at the National Carbon Capture Center. This technology offers significant benefits as it aims to reduce the regeneration energy requirements using novel solvents that are stable under the coal-fired power plant feed gas conditions. The Department of Energy will contribute $15,000,000 to the project.

  • Neumann Systems Group, Inc.: Carbon Absorber Retrofit Equipment (CARE). This project, located at the Colorado Springs Drake #7 power plant, will design, construct, and test a patented NeuStream absorber. The absorber will use nozzle technology proven during a recently completed 20 MW NeuStream-S flue gas desulfurization pilot project, and an advanced solvent that efficiently captures CO2. This absorber technology is applicable to a variety of solvents and can be added to existing pulverized coal power plants with reduced cost and footprint. Because of the modularity of the NeuStream technology, it can be rapidly scaled to larger size systems and retrofitted into existing plants with little risk. The Department of Energy will contribute $7,165,423 to the project.

  • Southern Company: Development and Demonstration of Waste Heat Integration with Solvent Process for More Efficient CO2 Removal from Coal-Fired Flue Gas. Southern Company will develop viable heat integration methods for the capture of CO2 produced from pulverized coal combustion using a waste heat recovery technology, High Efficiency System. This technology will be integrated into an existing 25 megawatt pilot amine-based CO2 capture process (KM-CDR) at Southern Company’s Plant Barry. Modeling by Mitsubishi Heavy Industries America indicates that a fully heat integrated High Efficiency System will improve by 26’ the thermal energy performance of the integrated KM-CDR and plant operation. The Department of Energy will contribute $15,000,000 to the project.

  • University of Kentucky Research Foundation: Application of a Heat Integrated Post-Combustion CO2 Capture System with Hitachi Advanced Solvent into Existing Coal-Fired Power Plant. Researchers plan to use an innovative heat integration method that uses waste heat from a Hitachi H3-1 advanced solvent carbon capture system while improving steam turbine efficiency. The proposed process also implements a process concept (working with the heat integration method) that increases solvent capacity and capture rate in the CO2 scrubber. The novel concepts and advanced solvent used in this study will significantly improve the overall plant efficiency when integrated with CO2 capture systems, and can be applied to existing coal-fired power plants. The Department of Energy will contribute $14,502,144 to the project.

"35% max increase in electricity cost"

Holy recession; Is it 2000 again?
Do we have a budget surplus?

Will this be combined with the high cost of EV batteries and increased taxes so the economy will really bottom?

So it IS true you cannot improve until you hit bottom?

Now I understand; Obama is way ahead of us.

Let's hope if any of these little adventures actually work that DOE sells its interest to oilcos - who should be financing CCS. Nothing to do with environment - CO2 streams are revenue for EOR operations and they oilcos should be paying for it.
