Advanced Combustion Systems

Date January 21, 2016, Funding Opportunity Announcement DE-FOA-0001459 entitled “Pre-Project Planning for Advanced Combustion Pilot Plants.” Contract Specialist: Diane Franklin. Application Due Date 03/22/2016. Applications and/or instructions can be found with this Funding Opportunity Announcement on FedConnect. For more information click here.

Projects resulting from this Funding Opportunity Announcement will complete preliminary designs of pilot plants based on advanced combustion systems. Pilot plants will be designed including identification of basic technology elements, integration requirements, identification of a host site, and cost and schedule requirements associated with the construction and operation of the pilots. The pilots will be at least 10 Megawatts electrical in scale or equivalent and contain essential design features to be assessed at the pilot scale prior to subsequent commercial-scale demonstration. Additionally a techno-economic analysis will be conducted at the commercial scale to evaluate the ultimate cost and performance relative to Department of Energy goals.

Researchers Uncover Copper’s Potential for Reducing CO2 Emissions in Chemical Looping

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

Chemical Looping Combustion

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).
