Interesting stuff Art, if storage is the solution to negative prices midday, than this might help:
One of the companies bidding for a 100-megawatt storage plant in South Australia is standing by claims that its technology could beat lithium-ion. Adelaide-based 1414 Degrees, named after silicon’s melting point (and formerly known as Latent Heat Storage), claims to have developed a molten silicon thermal energy storage system (TESS) that can store 500 kilowatt-hours of energy within a 70-centimeter cube. This is 36 times the capacity of a 14-kilowatt-hour Tesla Powerwall 2 lithium-ion battery, the company claims. 1414 Degrees says it could build a 10 megawatt-hour plant for around AUD $700,000 (USD $528,000), or a tenth of the price of a Tesla battery-based project.
