Project Description

The Ohio State University (OSU) will team with WorleyParsons (WP) to continue development of its chemical looping gasification (CLG) technology—an advanced air separation process that can be applied to produce electricity via integrated gasification combined cycle (IGCC) while achieving greater than 90 percent carbon capture and/or to produce chemicals via traditional catalytic reforming processes. Researchers will validate the feasibility of applying CLG technology by demonstrating the CLG process at a sub-pilot scale and conducting a techno-economic analysis of its applications for IGCC. A cumulative demonstration of greater than 100 hours will be performed with the 15kWth sub-pilot test unit to confirm the reliability of the reactors (reducer and oxidizer) and non-mechanical devices for maintaining controlled solid circulation, gas sealing, and coal distribution in the reactor (reducer) as well as to confirm sustained syngas production performance. OSU—with the support of WP—will conduct a comprehensive techno-economic analysis of the CLG process for IGCC application and compare it to the DOE baseline IGCC report. A highly reactive and attrition-resistant oxygen carrier was confirmed for chemical looping gasification applications in a previous Department of Energy funded project, DE-FE0012136.

Project Benefits

The success of this OSU project will lead to the development of a scalable CLG process design and confirm the economic advantages of this advanced air separation technology, justifying further scale-up to a pilot- scale demonstration unit. If commercialized, the CLG process could improve IGCC processes by eliminating cost-intensive unit operations. The CLG-IGCC process could increase overall plant efficiency by three to four percent and reduce the yearly cost of electricity by $20 per megawatt hour compared to the conventional IGCC approach.
