New phase change material storage concept including metal wool as heat transfer enhancement method for solar heat use in industry

Thermal energy storage is recognized as a key technology in the transition world facing today. But main technical barrier this has to achieve wider deployment low thermal conductivity of materials used, so-called phase change (PCM). This paper presents new concept for enhancement PCM tank using metal wool. Metal wool one least studied method enhance conductivity, while it high potential do so at cost. study shows experimental prototype that developed validation effective composite formed by NaNO3 salts and The used produced arranged ensure right porosity packaging increase 300% mixture. model validated confirms movement fluid during melting standardizes temperature molten material, increasing transference. also validates composite, with PCM, most promising be applications need heat stored around 280–300 °C. Such include use solar waste industry.
