“…The Alkali-Metal Thermo-electrochemical Converter (AMTEC) is an electrochemical device which utilizes heat from a solar or a nuclear source or from combustion of fossil fuels to generate electricity and is an excellent technology for conversion of heat to electricity (Weber, 1974 ; Cole, 1983 ; Ryan, 1999 ; Lodhi and Daloglu, 2001 ; El-Genk and Tournier, 2004 ; Wu et al, 2009 ). The AMTEC is thermodynamically somewhat similar to the Rankine cycle with conversion efficiencies in the 20–40% range, similar to the Carnot cycle.…”

“…These materials are known to have high ionic conductivity with ionic transport number for Na + or K + close to unity (Badwal, 1994 ). The electrolyte separates the high pressure (>20 kPa) and HT (700–950°C) section of the device from the low pressure (~100 Pa), LT (100–350°C) side of the cell (Weber, 1974 ; Cole, 1983 ; Ryan, 1999 ; Lodhi and Daloglu, 2001 ; El-Genk and Tournier, 2004 ; Wu et al, 2009 ). A schematic of the AMTEC is described in Figure 9 for a system based on sodium as the working fluid.…”

Electrochemical cells and systems play a key role in a wide range of industry sectors. These devices are critical enabling technologies for renewable energy; energy management, conservation, and storage; pollution control/monitoring; and greenhouse gas reduction. A large number of electrochemical energy technologies have been developed in the past. These systems continue to be optimized in terms of cost, life time, and performance, leading to their continued expansion into existing and emerging market sectors. The more established technologies such as deep-cycle batteries and sensors are being joined by emerging technologies such as fuel cells, large format lithium-ion batteries, electrochemical reactors; ion transport membranes and supercapacitors. This growing demand (multi billion dollars) for electrochemical energy systems along with the increasing maturity of a number of technologies is having a significant effect on the global research and development effort which is increasing in both in size and depth. A number of new technologies, which will have substantial impact on the environment and the way we produce and utilize energy, are under development. This paper presents an overview of several emerging electrochemical energy technologies along with a discussion some of the key technical challenges.

“…Various sources of exergy dissipation or entropy generation are interrelated, which represents inherent power loss to the AMTEC. The efficiency of this final conversion is governed by various irreversible kinetic and transport processes occurring at the electrode interfaces, within the BASE material, internal impedance, and thermal conduction and radiation losses [4,87,113]. Therefore, minimizing cell exergy dissipation or entropy generation directly maximizes cell power generation and efficiency.…”

SUMMARYThe alkali metal thermal to electric converter (AMTEC) is one of the most promising technologies for direct conversion of thermal energy to electricity and has been receiving attention in the field of energy conversion and utilization in the past several decades. This paper aims to present a comprehensive review of the state of the art in the research and development of the AMTEC, including its working principles and types, historical development and applications, analytical models, working fluids, electrode materials, as well as the performance and efficiency improvement. The current two major problems encountered by the AMTEC, the time-dependent power degradation and relatively low efficiency compared to its theoretical value, are discussed in depth. In addition, a brief comparison of the AMTEC with other direct thermal to electric converters (DTECs), such as the thermoelectrics converter (TEC), thermionics converter, and thermophotovoltaics converter, is given, and combinations of different DTECs to further improve DTECs' power generation and overall conversion efficiency are demonstrated. Future research and development directions and the issues that need to be further investigated are also suggested. It is believed that this comprehensive review will be beneficial to the design, simulation, analysis, performance assessment, and applications of various types of AMTECs.
