RESCOLL involves in thermoelectric paints development in the frame of THERMOPRINT Eurostars project

THERMOelectric Paints for exterioR and Interior eNergy Transformation

Context

Heating and cooling are largely dominated by fossil fuels (> 80%). This sector is heavily responsible for the EU's GHG emissions, and it is heavily reliant on energy imports. Most work in renewables for residential installation has focused on harnessing solar power. While being an extremely promising technology, solar power suffers from several drawbacks: it only works during a limited time of the day, depends on roof orientation, is heavily influenced by climatic conditions, and can be expensive to install. This leaves consumers with a long return on investment -typically five to seven years.

THERMOPRINT Technology

Solid state thermoelectricity is a promising and complementary technology, which converts heat directly into
electricity through the Seebeck effect. Thermoelectric generator (TEG) devices are very durable, having no moving parts or working fluids. They are completely silent, extremely scalable, compact, and have low payback periods – often three years or less. They have been applied in the aerospace and automotive sectors for industrial waste heat recovery. TEGs can provide solutions for improved energy capture and conversion efficiencies which are complementary to other energy capture and conversion technologies.

The THERMOPRINT project will develop and market high-efficiency thermoelectric paints for heat capture and
transformation. THERMOPRINT paints should generate electricity 24 hours/day. They should not depend on roof orientation, conform to nonplanar geometries and unusual configurations. They should be extremely easy to apply and maintain, and have a low cost of ownership.

Expected results

The THERMOPRINT project will develop and market high-efficiency thermoelectric paints for heat capture and
transformation. It will do this through two specific types of new products, with functional prototypes at the end of the project, using RESCOLL's headquarters as a demo site:

Paints for application in interior panels (e.g. drywall, ceiling tiles) for interior energy capture

Pretreated roofing tiles for exterior energy capture

Consortium

CIDETE will develop and produce the thermoelectric powders

RESCOLL will develop specialized paint formulations for the powders

PANCO will develop and produce the control systems and electronics for the thermoelectric paint systems

This project has received funding from the Eurostars-2 joint programme with co-funding from the European Union Horizon 2020 research and innovation programme.
