Alstom Power, through prior U.S. DOE funding, has been developing a limestone-based chemical looping combustion technology. The selected project will continue this work by enabling the full analysis of the process through an engineering system and economic study along with the development of a screening tool for process improvements. Additional analyses include an evaluation of pressurizing the limestone chemical looping combustion process.
This project focuses on development of the limestone chemical looping combustion system. The low-cost limestone oxygen carrier along with less-expensive more-efficient reactors drives down capital and operating costs relative to conventional systems. Specifically, this project involves addressing technology gaps and generating data to support scale-up via continuous, stable operation of a 1-MWe prototype system.
