a Sumitomo Corporation Group company, jointly demonstrated a new waste heat recovery system based on a thermoelectric generator (TEG), which generates electrical power via exhaust gas heat. The TEG unit was installed in the exhaust pipe at the downstream of the catalyst. The demonstration test was outsourced to FEV Europe GmbH.

The company also announced it will partner with Borla jointly to develop and to commercialize a next-generation-exhaust system incorporating PowerModules, with the goal of delivering significant fuel savings for commercial fleet truck fleets. Now, almost any owner of exhaust heat can generate valuable electricity. 2014.11.002.

Conceptual schematic of direct thermoelectric generator mounted in a vehicle’s exhaust stream. The exhaust energy content of Atkinson-cycle engines, which are used in many hybrid powertrains, is lower than conventional IC engines due to the cycle’s inherently higher thermal efficiency. Indirect configurations are also possible.

During deceleration and under braking, the electric motor acts as high-output generator to effect regenerative braking, optimizing energy management in the Lexus Hybrid Drive system by recovering kinetic energy (normally wasted as heat under braking and deceleration) as electrical energy for storage in the high performance battery.

The exhaust gas can reach temperatures greater than 900 °C, whereas the turbine upper functional limit is 850 °C. Considering that TIGERS is expected to harvest energy from the exhaust gas it is essential that it not only lives in this harsh environment it must also produce work with no impact on vehicle performance or fuel efficiency.

Researchers at the University of Manchester (UK) have developed a graphene-based nano-rectifier (“ballistic rectifier”) that can convert waste heat to electricity. Rectifying diodes let electrical current flow in only one direction; mainly used for power supply operation, they convert AC to DC current. —Song et al. Singh et al.
