Process simulation and analysis of a five-step copper–chlorine thermochemical water decomposition cycle for sustainable hydrogen production

  • An Aspen Plus simulation of a five-step Cu–Cl cycle is developed.
  • A more realistic user-defined electrolyzer model is simulated using Fortran.
  • The effect of production yields on reaction heats in each step is evaluated.
  • To achieve high CuO · CuCl2 yields, an excess amount of steam is needed.
  • Efficiency of the Cu–Cl cycle is calculated as 44% on the basis of the lower heating value of hydrogen.

Heat generation in high power prismatic Li-ion battery cell with LiMnNiCoO2 cathode material

The heat generation in a battery cell is calculated by measuring the overpotential resistances with four different methods and entropic heat generation in the cell. Calorimeter tests are carried out to compare the calculated and measured heat generation.

Evaluation of GTHTR300A nuclear power plant design with dry cooling

GTHTR300A is a high-temperature gas-cooled reactor power plant design with exclusive dry cooling. The reactor coolant is used to drive a direct-cycle gas turbine, and further dry systems are provided to meet the three general cooling requirements. By reliance on economic and safe dry cooling, the design succeeds in making inland construction feasible even without source of cooling water, and the resulting benefit to safety and environment is compelling as described in the article.

Latent heat energy storage characteristics of building composites of bentonite clay and pumice sand with different organic PCMs

In this study, six new kinds of BCPCMs, BC/PEG1000, PS/PEG1000, BC/octadecane, PS/octadecane, BC/CA–MA, and PS/CA–MA composites, were prepared. The BCPCMs were characterized by SEM, FT-IR, DSC, and TG techniques. The DSC measurements indicated that the LHTES properties make them promising BCPCMs for low temperature-passive TES applications in buildings. Thermal cycling test and TG analysis indicated that they have good thermal reliability, chemical stability, and thermal durability. In addition, the thermal conductivity of BCPCMs was enhanced considerably by addition of EG.
