NETL Advances Copper-Hybrid Oxygen Carrier for Chemical Looping
Back in February, we shared that DOE’s National Energy Technology Laboratory (NETL) researchers were exploring the potential of using copper in a process known as chemical looping to capture carbon dioxide (CO2) emissions from coal-fired power plants. Their research is bearing fruit as more than 40 hours of chemical looping operations have been conducted using copper —a new lab record. Read More!
DOE, Natural Resources Canada Announce Pilot Plant to Advance Oxy-Combustion Carbon Capture
The U.S. Department of Energy (DOE) and Canada’s Natural Resources Canada (NRCan) today announced the opening of a new 1 Megawatt Thermal (MWth) facility to test an advanced process to capture carbon dioxide (CO2) emissions from coal-fired power plants. The announcement was made during a ribbon-cutting ceremony at the facility in Ottawa. Read More!
REQUEST FOR INFORMATION: Topics for Advanced Combustion Systems of the Future Department of Energy National Energy Technology Laboratory
September 27, 20016 – The purpose of this Request for Information (RFI) is to seek input from industry, academia, research laboratories, government agencies, and other stakeholders on advanced combustion systems research areas that can improve existing power plants, lead to commercialization of innovative technologies and approaches applicable to power plants, advance marketable products and/or industrial coal use, and create advanced combustion systems of the future. Responses to this RFI could be used to inform topics for a National Energy Technology Laboratory (NETL)-hosted Advanced Combustion Systems Technology Workshop. This is solely a request for information and not a Funding Opportunity Announcement (FOA). U.S. DOE is not accepting applications. Read More!
| Advanced Combustion is an Alternative for Post-Combustion Carbon Capture…
Advanced Combustion technologies separate gases at the front end of the power generation process as a cost competitive alternative to post-combustion capture.
Advanced combustion power generation combusts fossil fuels in a high-oxygen (O2) concentration environment rather than air. This eliminates most, if not all, of the nitrogen (N2) found in air from the combustion process, resulting in flue gas composed of CO2, water (H2O), contaminants from the fuel (including coal ash), and other gases that infiltrated the combustion system. The high concentration of CO2 (≈70 percent) and absence of nitrogen simplify separation of CO2 from the flue gas for storage or beneficial use. Thus, oxygen-fired combustion is an alternative approach to post-combustion capture for carbon capture and storage (CCS) for coal-fired systems. However, the appeal of oxygen-fired combustion is tempered several challenges, namely capital cost, energy consumption, operational challenges of supplying O2 to the combustion system, air infiltration that dilutes the flue gas with N2, and excess O2 that must be removed from the concentrated CO2 stream. These factors mean oxygen-fired combustion systems are not affordable at their current level
of development. Advanced combustion system performance can be improved by two means: (1) by lowering the cost of oxygen supplied to the system and (2) by increasing the overall system efficiency. The Advanced Combustion Systems Program targets both of these possible improvements through sponsored cost-shared research into three key technologies: (1) Oxy-combustion, (2) Chemical Looping Combustion (CLC), and (3) Enabling Technologies/Innovative Concepts.
NETL is funding projects within each of the above-mentioned approaches. These R&D efforts are being performed both externally by industry, research organizations, and academic institutions, and internally through NETL’s Office of Research and Development (ORD).
