Too much salt is not just bad for your health. It could also harm the likelihood of thermal energy storage (TES) cost reduction across the entire concentrated solar power (CSP) industry.
Right now, molten salt TES is seen as critical in justifying the high cost of CSP versus other renewable energy sources, such as solar PV or wind.
TES allows CSP, or solar thermal energy, to deliver stable, round-the-clock power, which is more valuable to grid operators than the intermittent generation provided by renewable alternatives.
But it is just possible that a growing preference for molten salt among CSP developers could hamper the chances of adopting more efficient and cost-effective types of TES.
