Corrosion of steel alloys in molten NaCl + Na2SO4 at 700 °C for thermal energy storage

Design of new molten salt thermal energy storage material for solar thermal power plant

In order to obtain molten salt with lower melting point, higher thermal stability and reduced cost relative to previously available materials, a variety of molten salt mixtures of alkali nitrates are investigated by experimental methods. However, since measurements are generally expensive and time-consuming, it is of interest to be able to predict melting point and the component of multi-compon...

Electrochemical assessment of imidazole derivatives as corrosion inhibitors for mild steel in 3.5 NaCl solution

The corrosion inhibition efficiency of benzimidazole, 2-methylbenzimidazole and 2- aminobenzimidazole for mild steel immersed in 3.5 NaCl solution was investigated by electrochemical impedance spectroscopy EIS at concentration range from 10-5 to 10-2 M of imidazoles and temperature range from 30 to 50°C. In addition, DC polarization was examined to determine inhibition mechanism at concentratio...

Thermal Analysis of Solar Thermal Energy Storage in a Molten-Salt Thermocline

Cyclic Operation of Molten-Salt Thermal Energy Storage in Thermoclines for Solar Power Plants

High Temperature Phase Change Materials for Thermal Energy Storage Applications: Preprint

To store thermal energy, sensible and latent heat storage materials are widely used. Latent heat thermal energy storage (TES) systems using phase change materials (PCM) are useful because of their ability to charge and discharge a large amount of heat from a small mass at constant temperature during a phase transformation. Because high-melting-point PCMs have large energy densities, their use c...
