Technology
Roughly 60% of global primary energy consumption is lost as waste heat. This represents a huge energy recovery potential: Transforming waste heat into useful energy could contribute to a smaller carbon footprint – and at the same time reduce the cost of useful energy.
Thermoelectric materials are a class of advanced materials producing electricity directly from heat. TEGMA develops systems for thermoelectric applications.

Applications
Thermoelectric generators (TEG) may be utilized in a variety of markets with large amounts of waste heat, including:
Automotive
Reduced CO2 emissionsTEGma is developing thermoelectric solutions suitable for integration in the exhaust systems of both personal cars and trucks.
Shipping
Reduced fuel consumptionTEGma has verified its patented TEG system technology through several pilot systems installed in ships in operation.
Process Industry
Increased energy efficiencyTEGma is currently developing and testing TEG systems with partners to recover waste heat from the process industry.
Sensor power
Battery-free wireless sensorsTEGma is in the process of developing a unique TEG system which can act as a “battery” for wireless sensor networks.
Our vision
TEGma will become a leading supplier of complete thermoelectric solutions
About TEGma
TEGma is established in a market characterized by a strong need for waste heat recovery solutions. TEGma has completed several pilot installations of TEG systems in industrial environments and is currently commercializing its products to meet the market needs.
Cooperation with leading research institutes and universities provides access to relevant competence and technology. Joint development with customers and suppliers ensures processes and systems suitable for large-scale industrialization, and applications that address key customer needs.
Thermoelectric modules are solid-state devices with many similarities with photovoltaic solar technology, both on the process and product side. TEGma is thus benefiting from the extensive photovoltaic experience and know-how in the Scatec group, the owner of TEGma.
Scatec is Alf Bjørseth’s company for developing new business ideas within the areas of renewable energy and environmentally friendly advanced materials.
