Renewable energy from industrial waste heat using thermoelectric generators.

The start-up

Thermoelectric generators have been developed that convert industry waste heat into electricity and which can be used directly for applications onsite, or re-injected into the grid. These waste heat recovery units can be installed at every chimney or pipe where heat is present, to create a modular, scalable and maintenance-free system.

The additional development of an industrial self-powered wireless sensor network system for industry 4.0 allows industries to install wireless self-powered sensors that monitor their processes.

The need

Industries are inefficient at using energy. More than 60% is wasted in the form of heat. Reducing the cost of the energy bill and lowering the environmental impact of energy are both essential.

At the same time, industries need to monitor their processes when installing sensor grids. Wiring is very expensive and wireless solutions require batteries to feed the sensors, which can also be costly.


The solution

An initial solution provided is sustainable and eco-friendly energy production using a by-product of the industrial process itself: heat. Converting waste into usable energy reduces energy bills and lessens the environmental impact made in industry, aligning it with the requirements of new environmental rules.

The additional provision of a self-powered sensor system, that can be installed everywhere where heat is present, makes installation easier and lowers costs, as well as providing a wireless sensor platform which matches industry 4.0 requirements.


Value proposition

In contrast to current waste heat recovery systems based on steam-powered machines, such as the organic rankine cycle systems which are huge, very expensive and have high maintenance needs and operation costs, the waste heat recovery system is a flexible solution which can be easily installed in every industry, as it can be attached to any pipe or chimney where heat is present. The system is scalable, modular and maintenance-free with an estimated operative life of over 20 years. The system can also be upgraded with new technologies for higher performance. Installation does not require complex re-engineering from industry processes; it is simply ‘plug and play’.

A solution has also been found to drastically reduce the cost of industrial monitoring, limiting wiring and eliminating the need for batteries in wireless sensor networks. Customers will be able to integrate collected data in a personal SCADA system or monitor it using a specific application treated in a Fiware big-data framework.


A close collaboration is already at play occurs with CIDETE, the Spanish TEG cells manufacturer, as technical partner and supplier. Collaboration agreements have also been made with the Autonomous University of Barcelona (Spain) as well as punctual technical collaborations planned with Harvard University, Boston, MA (USA).


In August 2016, a pilot waste heat recovery Unit was installed in the SEAT factor (Volkswagen group) in Martorell, Spain. Three more pilot projects will be conducted for Q1 2017, a project for REPSOL oil refinery – one of them a WHRU, and two, (INDUEYE) self-powered wireless sensor systems. Five other big multinational companies have also shown interest in testing proposed solutions in different sectors and industrial environments.
