An energy storage system based on solid‐solid phase transition of crosslinked polyethylene was constructed and tested. The energy storage unit consisted of a column packed with crosslinked polyethylene tubes. The solid‐solid phase transition enables heat transfer by direct contact between the form‐stable polymer and the hot (cold) fluid. A theoretical model for the simulation of this system was developed. The heating‐cooling characteristics of the energy storage system were simulated by the model, using measured thermodynamic properties of the crosslinked polyethylene. The potential of various crosslinked polyethylene materials for energy storage applications will depend on sufficient high‐temperature stability.
