Project Description:
The purpose of this project is to evaluate the technical feasibility of using the waste heat in the exhaust stacks of power generating equipment to decompose CO2 through the use of solid oxide membranes and to then mix the decomposed elements (CO and O2) into the fuel stream to augment combustion thereby increasing thermal efficiency.
Proposed Outcomes:
· Membrane technology that will be appropriate for the direct thermal decomposition of CO2.
· Quantification of the combustion characteristics of fuel blends of CH4/CO/CO2/O2/N2.
· Feasibility assessment based on prototype membrane and combustion testing.
Anticipated Benefits:
· Reduce the cost of power generation in systems that utilize combustion by using the waste heat to improve thermal efficiency or by selling the decomposed elements (CO and O2) to partially offset the cost of generation.
· Reduces CO2 emissions and would enable CO2 sequestration if desired.
