Thermal battery with 6-8 times the energy density of lithium

Molten silicon. Grid-level storage, not for vehicles. They claim 60%-80% the cost of lithium.

I didn't see Rossi's picture in the article, but a thermal generator with only 3 moving parts? Suggests thermoelectric generator with efficiencies ranging from 6% to 15%, that doesn't seem like a very good deal to me.

If all they have done is increase the effective life an order of magnitude at constant outlay it seems quite significant.

Li-ion even at $100/kWh is 1-10 cents per kWh with a lifetime of 10,000-1,000 cycles. The bottom end of that range gives very expensive power. If they really can deliver 25 years of diurnal cycling, moving to the top end of the range, the cost of intermittency of renewables starts to look reasonable - provided annual maintenance for the (glowing red-hot) packages isn't too high....

FWIW 1.2 MWh in a shipping container is doesn't seem like 6-8 times Li-ion to me.

Climate Change Technologies, also known as CCT Energy Storage, has launched its TED (Thermal Energy Device) with a set of remarkable claims.

Remarkable claims require remarkable proof. I have yet to see either in this case.
Pumped hydro still remains the cheapest most economical way to store energy. IMHO
Sites abound but due to environmentalist and NIMBY (Not in my back yard) thinking this idea will never get off the ground.
Maybe we should start over and give the cockroaches a chance.
