Sustainable and Affordable Half-Heusler based Thermoelectric Converters for Utilization of Waste Heat into Electrical Power in Maritime Applications - MarTEnergy

Project summary

The main objective of the proposed research is to develop highly efficient half-Heusler (HH) based prototype thermoelectric (TE) converter consisting of non-volatile cost-effective elements for operating temperatures ranging up to 700oC (n-type ANiSn and p-type ACoSb (A=Ti, Zr, Hf)), covering most of the potential applications conditions, including maritime gasoline engines. Overall, the objectives of the MarTEnergy are: (a) Synthesis of cost-effective highly efficient HH based compositions (b) Development of highly durable, compatible and stable joining techniques between the TE semiconductors and the involved metallic joints (c) Integration of the entire components into practical devices (d) Finite element analysis on the prototype converter performance prediction in the maritime shipping industry to improve competitiveness and strengthen the maritime sector leadership. TRL levels start from 2 (technology concept formulated) to 4 (technology validation in lab).
