D APPENDIX D: TECHNOLOGY SOLUTIONS FOR ENERGY RECOVERY E. Thermoionics Thermionics or Direct Energy Conversion is the process by which energy is converted from one form of energy to another form without the benefit of a prime mover. A study conducted at MIT in the mid-1990’s involved an investigation of using thermionics to eliminate the prime mover and enable a fully electric drive system. While this is the main function of thermionics, other applications may include energy storage and cooling. One of the primary drawbacks of thermionics at present is the fact that it is only effective at input temperature of 1000oC or above. At this temperature level, it could only be used at nuclear power plants or in the space program. The capability of this technology needs to be developed to fulfill requirements of advanced power electronics or waste heat conversion before this concept may be applied. Solid state thermionic devices could, however, capture waste heat energy and convert it into electricity without creating additional pollution. The technology also can be reversed to provide an efficient means of cooling. Current thermoelectric technology can convert only 10 percent of the heat it absorbs. However, new thermionic technology is capable of 35% conversion efficiency of the Carnot limit. MIT, with the Salt Lake City- based company ENECO, has developed a semiconductor technology that efficiently and affordably converts heat into electricity using solid state thermionics, a combination of thermoelectrics and thermionics. Recent interest in solid state thermionics has spurred ENECO scientists to combine the two sciences to produce a single, solid state device that exhibits the best features of both technologies, namely higher conversion efficiencies at lower operating temperatures than previously achieved by either technology. Utilizing InSb and HgCdTe based materials, recent technology advances have demonstrated high heat-to-electricity conversion from 100oC to 300oC, temperatures typical to waste heat. What is not known at the present time is the magnitude of the technology’s ability. Significantly higher efficiencies and operating temperatures are predicted as materials are optimized. ENECO’s device is a sandwich of three layers of semiconductor. One of the outer layers is heated and the other is kept at RT. The middle layer is an insulator that maintains the temperature difference. The heat causes electrons to eject, generating an electrical current. Originally developed under a DARPA grant in 2000, testing is being conducted under follow-on DARPA funding. The company claims the technology produces low acoustical and electrical signatures which, if proven true, may be useful for thermal management for future weapon systems. 115PDF Image | Analysis for Recovering Energy from Industrial Waste Heat
