- Schroedingersat 4y agoWater is the best option for being driven from a heat pump over a few days in most cases. Phase change materials like sodium acetate or thermochemical systems like NaOH + water seem to work well on paper for long term storage, but haven't received much attention for some reason.
- ulrikrasmussen 4y agoAs far as I understand: Water is best for heat pumps because it has a high heat capacity and the operating temperature is below boiling point. Rocks and salt is used for high temperature storage.
