It's clearly not ready for production yet, but storing energy as concentrated heat seems like one of the plausible proposed grid-scale storage solutions to me. I'm interested to see where this goes.
- diarrhea 5y agoConcentrated energy is not a technical term. But high-temperature internal energy storage (aka heat storage) is terrible because of the losses. For example, low temperature floor heating is very efficient. You don’t want high temperature deltas because of the associated exergy losses.
