Not to knock a new & promising tech but I don’t see what the advantage of the magnesium-antimony battery over the sodium-sulfur
The Mg_Sb cell is twice as hot and at ~69% efficiency, is almost 20% less efficient than a NaS battery.
It may be less corrosive than NaS but that seems to be the only advantage.
It is interesting to see energy stored per $ going up all the time, across a range of techniques. These liquid metal batteries may provide a cheaper alternative than traditional deep-cycle batteries for off-grid dwellings, which bodes well for third-world economies.
Questions in my mind cover such matters as expected life, safety in the environment and energy density, although the latter looks pretty good if a shipping container could store enough energy for a small community.
It will be fascinating to see how this technology plays out commercially.
Would commenters to a post with a video please watch the video BEFORE commenting. “My” statement about storage was NOT “my” statement, rather a very simplified form of what Mr Sadoway had said during his presentation.
I would ask that commenters who post statements that are not their own opinion indicate this, as it’s really not difficult.
1) It’s seems that Mr Sadoway is implying that “No batteries = no wind + no solar”
2) So the speaker believes that wind & solar energy, without responsive storage, is impractical or problematic.
And it takes only a few words to make your own position quite clear.
“Sadoway thinks that wind & solar energy, without fast storage is useless | troublesome | unreliable” – followed by “I concur” or “I do not agree”
