One point in the video talks about that this is novel/interesting because it can handle much higher heat then other thermal storage systems. But at the end of the video it talks about the output being only a bit above 150 degrees. Isn't that completely contradictory? If I want to use this in a steel forge this isn't even remotely close enough.

Energy is extracted via a heat exchanger. The rate of heat flow in a heat exchanger is proportional to the temperature difference between the hot and cold sides. The closer they are to thermal equilibrium, the slower you can extract energy.

That's just for district heating, right? They can degrade the heat down to 150 F for that purpose. If they really wanted to, they could extract some power from the high grade heat and produce 150 F waste heat.
