INTEGRAL

INTEGRAL is a 3 year collaborative project within the Call for Proposals (H2020-IND-CE-2016-17) of the PILOTS-01-2016. The aim of the INTEGRAL project is to upscale the second generation of thermoelectric material technology using existing pilot lines, in order to address mass markets (transport, process industries), and produce advanced functional materials with customized electrical and thermal conductivities.

 

- Total budget: 8.845.948 €

- Duration: 2016/12/01 - 2019/11/30

The project

Transport, notably automotive, and process industries, in particular metallurgy, glass and chemicals, are today responsible for a large amount of waste heat above 140°C, estimated to reach 5 000 GWh/year, worldwide. Directly generating electricity from waste heat by means of thermoelectric generators could therefore significantly reduce the global carbon footprint of these activities. However, thermoelectric materials have not yet found their way into mass markets due to lack of sustainable sources of materials for production, progress to be made on the required material performance and an industrial production capacity.

As a new generation of thermoelectric materials are attracting a growing interest for waste-heat recovery and autonomous temperature control in industry, pilot lines resulting from partnerships between public research institutes, industrial research teams and SMEs are emerging in Europe. The aim of the INTEGRAL project is to upscale this new generation of thermoelectric technology, using existing and growing pilot industry lines, in order to address mass markets (transport, process industries), and to produce advanced functional materials with customized electrical and thermal conductivities. The INTEGRAL project is unique since it gathers leading companies developing these materials in Europe. Furthermore, the large-scale manufacturing processes to be developed for producing nanostructured materials within the project cut across multiple sectors to find a wide range of applications outside thermoelectrics, i.e. where customization of electrical or thermal properties of sintered or casted materials is needed. Finally, a technology transfer will be performed towards the commercialization of a new generation of advanced multifunctional materials with a circular economy vision.

Our specific objectives are:

- To develop customized multifunctional new generation thermoelectric materials

- To upscale the new generation thermoelectric materials fabrication processes on existing pilot industrial lines

- To develop in-line real-time characterization of the materials and process control

- To demonstrate the performance stability and efficiency improvement of the functionalized new generation of thermoelectric materials

- Perform a technology transfer on the upgraded pilot lines

- Prepare the commercial deployment of new generation of advanced multifunctional materials with customized electrical and thermal properties with circular economy vision

Partnership

The consortium of the INTEGRAL project comprises 13 organisms from 8 European countries, gathered to bring up the best in the next generation of thermoelectric materials. We have industries, small enterprises, research centres with various expertise required for the success of the project:

- Experts in thermoelectric generators for automotive heat recovery from Valeo (France)

- Experts in thermoelectric generators for exhaust gas recirculation cooler, with Ricardo (United Kingdom) and heavy duty truck engine cooling with Titan X (Sweden)

- Experts in industry heat waste from Elkem (Norway) and autonomous temperature control in industry with ArcelorMittal (Spain)

- Nanostructured Material production by high energy ball milling with MBN Nanomateralia (Italy)

- Silicon thermoelectric ring design and production with Hotblock On Board (France)

- Cast silicon thermoelectric modules with strip-legs design and production with RGS Development (The Netherlands)

- Half-Heusler cubic-legs design and production with Isabellenhütte (Germany)

- Thermoelectric material customisation for thermal and electrical conductivity with Cidetec (Spain)

- Thermoelectric generators prototyping line, as well as material shaping and tuning, and in-line process control with the POUDR'INNOV 2.0 Powder Metallurgy Platform at CEA Liten (France)

- Sintering and off-line ageing and characterisation with Fraunhofer IKTS (Germany)

- New material life cycle analysis and cost targeting with Efficient Innovation (France)

Our role

The role of CIDETEC is to modify the surface of thermoelectric material powders by depositing nanocoatings. The surface modified powders will be used as key material for an innovative grain boundary engineering strategy to obtain bulk thermoelectric materials (i.e. by sintering) with customized thermal and electrical conductivities. Furthermore, Cidetec leads the dissemination an exploitation activities.
