OTE-POWER

Associated with many industrial and social activities of mankind, a large amount of thermal energy is available from the waste heat. Thermoelectric conversion offers a very promising method to convert waste heat directly into electricity, thus improves the energy efficiency and reduces the CO₂ emission. Here, we are working on the thermoelectric materials and modules which will be used at high temperature environments and composed of nontoxic, low-cost oxides.

The partners in the project consortium have outstanding international expertise within thermoelectric research and development. Our research groups represent five leading laboratories in Denmark, Japan and the US, while industry participation ensures strong links to both technology providers and end-users.

· Enhancement of the Thermoelectric Performance of p-Type Layered Oxide Ca₃Co₄O_9+δ Through Heavy Doping and Metallic Nanoinclusions

An effective way to improve the thermoelectric performance (ZT) of layered structured oxide materials by carefully choosing heavy ion doping and introducing metallic nanoinclusions is proposed. A p-type oxide material with remarkable highly improved ZT is successfully fabricated using this approach. Long-term durability at high temperature testing confirms this material is a very promising p-type material for high temperature power generation.
