• The Consortium discusses the development of technologies and businesses based on “Thermoelectric Conversion Modules” in order to contribute to the social environments of the future.


  • Under an Agreement of Confidentiality, the Consortium provides an opportunity for various industrial entities to exchange information. The Working Groups (WG) created within the Consortium are designed to enhance these merits.


  • The members of the Consortium include a broad range of companies, from ‘upstream’ companies that supply materials, to ‘downstream’ companies who provide modules or power sources. Each member company makes every effort to create practical applications for the technologies that they all possess.

What is the merit of using TEG for waste heat recovery system ??

In order to meet the requirements for a steady supply of energy and for prompt responses to the problems of global warming, improvements in energy efficiency are urgently required. The ratio of fossil fuels that are used as a primary energy source in Japan has reached 80%.

Furthermore, more than 70% of the energy derived from fossil fuels is eventually dissipated as waste heat. Converting this waste heat to value-added electrical energy and then utilizing it could improve the efficiency of fossil fuel use, resulting in a significant contribution to the reduction of CO2 emissions.

 In order to recycle waste heat, a method of generating electrical energy that encompasses scalability is required. To this end, we are focusing on the “solid state thermo-electric conversion method”. Thus, through our development of low-environmental load thermoelectric-converting materials, the modules and the power generating system, we are making efforts to reduce CO2 by following the philosophy that “wherever there is heat, there is a power station”. In the present energy systems that rely so heavily on fossil fuel energy, recycling waste heat to energy is extremely important to improve the efficiency of energy use.

An industry-academic joint research body, the Waste Heat Recovery Technology Consortium, was established to advance the development of ‘next generation’ low environmental-load thermo-electric conversion materials and modules, which we expect will enable high-conversion rates (more than 10%) and will be pro-environmental and bio-adaptive. The materials that we are using can convert waste heat at 300 – 500°C into usable electrical energy.
