The US Department of Energy (DOE) has selected eight projects to develop enabling technologies for advanced combustion systems, including oxy-combustion and chemical looping–based power systems.
The total estimated federal investment in the eight projects exceeds US$10 million. Funding amounts may vary as negotiations progress.
By developing efficient and economically viable combustion systems that generate electricity with near-zero emissions, DOE’s Advanced Combustion Systems Program contributes to the Administration’s priority of addressing climate change by reducing greenhouse gas emissions. Central to the program are systems based on oxy-combustion, in which fuel is combusted with oxygen rather than air, and chemical looping combustion, in which oxygen is supplied to the fuel via a solid oxygen carrier. In both cases the resultant fluegas is a concentrated stream of carbon dioxide, enabling efficient and effective carbon capture.
The Energy Department is focused on driving down costs and collecting engineering data for scale-up of advanced coal-based power systems. The newly selected projects will improve the overall economics for these two technology pathways, ensuring that their technical performance and cost are substantially better than today’s baseline pulverised coal power plant with post-combustion capture. The projects will also support these technologies by addressing critical technology gaps and improving overall system performance.
The selected projects are in two topic areas: (1) research to improve the performance of pressurised oxy-combustion systems, and (2) research to improve performance of chemical looping combustion systems using coal-based solid fuels. Both topic areas aim to capture 90% of the CO2 produced in the targeted systems without the need for post-combustion capture systems.
All eight projects will be managed by the Office of Fossil Energy’s National Energy Technology Laboratory (NETL).
