Описание: Dr Mehdi Khatamifar (JCU) explored thermal energy storage - particularly ice-based and phase-change material (PCM) systems - as a tool to improve building energy efficiency in tropical climates. He outlined the growing Asia-Pacific market, Australia's renewable integration challenges, grid stability issues and the value of shifting peak loads via time-of-use tariffs. In humid tropical conditions, where latent heat (humidity) forms a large share of cooling demand, ice thermal storage offers better humidity control than conventional air conditioning. He described JCU's early-stage prototype using sealed aluminium cans as modular thermal cells with glycol as the heat-transfer fluid, reporting 30-45 % power savings and up to 14 hours of cooling in tests. Key future work includes flow optimisation, uniform charge/discharge control, modular packaging and hybrid/cascaded designs to reach manufacturing maturity suitable for household and small-building applications.
