Thermo-electrochemical Capacitor Device / Conversion of Low-grade Waste Heat into Electricity
(REF: S-0158) |
| Matched I&T Wish |
|
| Trial Project |
|
| Solution Feature |
- HPS team invented a Thermo-Electrochemical Capacitor (TEC) using asymmetric electrodes, a carbon base cathode and a polymer anode in iron redox electrolyte via isothermal heating operation without building thermal gradient or thermal cycle.
- The invented TEC achieved heat-to-electricity conversion efficiency (η) over 3.5% at low-grade heat regime below 90°C (>20% of Carnot efficiency ηc), surpassing all existing thermo-electrochemical and thermoelectric systems.
- When heated, TEC generates voltage via thermo-pseudocapacitive effect of cathode and then discharges continuously by the oxidation of anode and the simultaneous reduction of redox couple. The system can be self-regenerated when cooled down; this synergistic mechanism allows the cyclability of TEC.
- Energy conversion from primary energy carriers to the final energy of use is subject to considerable losses equivalent to about 72% of the global primary energy consumption. The major loss is identified as waste heat and 63% of them are regarded as low-grade heat below 100°C.
- As low-grade heat is abundantly available in industrial processes, environment, biological entities, solar-thermal and geothermal energy, we believe that this game-changing electrochemical technology will lead to new and practical applications for efficiently converting low-grade heat to electricity.
