Energy Conversion and Power Generation Using conductance, and (c) energy-conversion efficiency. The Nanofiuidics, Fig. 3 Ionic concentration (n ) effects parameters are same as those in Fig. 2 on (a) electric conductance, (b) hydrodynamic... 

In this entry or chapter, we introduce two kinds of typical energy-conversion and power-generation schemes using nanofluidics. We analyze the ion transport rules or mechanisms through one single nanochannel and obtain some interesting results, which may help to improve designs and optimizations of... 

Figure 1.1.17 The solar refinery as the conceptual contribution of chemistry by chemical energy conversion to the sustainable use of renewable energy. The upstream part (hydrogen generation) and the downstream parts need not to be colocalized in a practical realization. CSP stands for concentrated solar power. Green boxes indicate solar fuel products blue boxes stand for intermediate platform chemicals. The red arrows indicate flows of solar hydrogen to a storage and transport system for large-scale applications. The blue arrows show the major application lines for chemical production of solar fuels. The scheme also indicates the role of fertilizers from ammonia required in sustained use of biomass for energetic applications.

Development of collector electrode materials with lower work function ( 1.0 eV) is the most effective methods to improve energy conversion efficiency of a thermionic converter. At present refractory metals such as Mo, W, Nb with cesium adsorption are used as a collector with the work function values of about 1.7eV. It is suggested that metal oxide collectors can adsorb cesium more strongly and show lower values of work function. In the study, refractory metal oxides and AgO x were experimentally examined concerning the work function values and high temperature durability. A research thermionic converter of a W emitter and an AgO x collector was fabricated and power generation tested to examine the effectiveness of the AgO x collector. A new type of a FGM collector which integrates a... 

CHP modules nominally produce 1 and 3.5 kW, respectively. While the 166 model is comprised of one MEA stack of 65 cells, the 390 model uses three MEA stacks each with 89 cells. Both of these systems are able to tolerate fuel impurities up to 5% CO concentrations and 10 ppm H2S at 160°C. Because the excess energy can be used to heat up air or water, Serenergy claims that over 80% of the total heat and power generated can be used and that the system efficiency is as high as 57% (the efficiency data was not available). These systems can also be used as auxiliary energy conversion devices.
