This project will identify the most promising compositions of ferroelectric materials that can be used to make highly efficient thermoelectric devices for waste heat recovery in coal fired power and industrial plants. Combinatorial methods will be used to rapidly screen a broad composition range with high Curie temperatures, followed by an investigation of the thermoelectric properties. Processing approaches to making the materials will be also developed.
This project will explore a novel class of ‘n’ type thermoelectric oxides that are stable at high temperature in the coal-fired flue gas. The result will be highly efficient thermoelectric devices for waste heat recovery in coal fired power and industrial plants. Improvement to high-temperature advanced-materials will promote the development of advanced power plant designs that can operate at higher temperatures and pressures, leading to improvements in efficiency, operational flexibility, lower operating costs.
