Comparing water and paraffin PCM as storage mediums for thermal energy storage applications

PERFORMANCE OF PARAFFIN AS PCM SOLAR THERMAL ENERGY STORAGE K.Kavitha and S.Arumugam

The continuous increase in the level of greenhouse gas emissions and the rise in fuel prices are the main driving forces behind the efforts for more effectively utilize various sources of renewable energy. In many parts of the world direct solar radiation is considered to be one of the most prospective sources of energy. In this study, the thermal performance of a phase change thermal storage d...

Studies on Paraffin-Graphite-Cu PCM Composites for Solar Thermal Storage Applications

In this paper an experimental investigation on the thermal storage capacity for a typical composite mixture of paraffinGraphiteCu PCM composite has been studied. Paraffin wax was used as the base phase change material (PCM) and the paraffin has been mixed with Cu turnings in different ratios 10, 50, 70 and 90 weight percentages and considered as a composite. The thermal charge and discharge cap...

Pcm-graphite Composites for High Temperature Thermal Energy Storage

Numerical evaluation of multi-layered solid-PCM thermocline-like tanks as thermal energy storage systems for CSP applications

The two-tank system is the technology used for thermal energy storage (TES) in current concentrating solar power (CSP) plants. Thermocline storage concept has been considered for more than a decade as a possible solution to reduce the high cost of the storage system in these plants. In previous works, multi-layered solid-PCM (MLSPCM) thermocline-like storage tank configurations has been introdu...

Preparation and Characterization of Paraffin/palmitic Acid Eutectic Mixture in Thermal Energy Storage Applications

Thermal Energy Storage using phase change materials has become an interesting area of energy research because of its high energy storage density, isothermal nature of storage process and small volume changes. There are wide ranges of phase change materials available commercially. This work deals with paraffin and Palmitic acid eutectic mixture in three different proportions as phase change mate...
