Heat storage without degradation: why doesn’t a thermal buffer wear out?
Heat storage without degradation sounds like a marketing claim. It’s a direct consequence of the technology involved: a lithium battery returns less energy after ten years than on day one. A PCM that has melted and solidified hundreds of times loses part of its capacity to subcooling and phase segregation. A salt buffer that’s heated…

Overview of phase change materials: properties, advantages and limitations
Phase change materials: overview of PCMs for thermal storage Phase change materials, or PCMs, store heat during a phase transition. In practice, latent heat is only part of the story: sensible heat, thermal conductivity, cycling stability, corrosion, safety and cost are often just as important. This overview is intended as a technical selection map: temperature…
