Storing heat energy seems like an incredibly inefficient way to store energy.
+90% efficiency. It drops when converting to electricity.
The article I read said they don’t currently have an efficient way to convert it back to electrical energy. Current tech is 30% efficiency.
Interesting idea but i think we’re many years from this being commercially viable.
While it can be used in localized electrical power generation, this isn't exactly best suited for just that. According to the video, the typical household uses 60% of their energy towards heating on average. This type of battery would already be storing thermal energy in the form that you need for this, so any conversion losses would already be accounted for; it would just be radiative losses while distributing the heat.
