Is there any constraint on what types of salt or salt compounds are usable for energy storage? Or does it not really matter for the most part?

- lawrenceyan 8y agoNot really, though a commonly used thermal salt is the eutectic mixture of 60% sodium nitrate and 40% potassium nitrate, which can be used as liquid between 260-550 °C. Table salt, or sodium chloride, has a melting point of around 800 °C. So it really depends on what attributes your looking for.
