I didn't see anything about round trip efficiency. I've heard that's a big downside so it might make energy storage a hard sell.
97% RTe from what I've heard.
That would be awesome, any idea where you heard that, I've read other sodium based technologies have ~65%

This article is saying 93% but I thought I'd seen 97 somewhere. Might have been marketing bullshit. Though this paper is 3 years old now, so there's been time for improvement. What hits the market right now may not be up to that number either, so I wouldn't disbelieve 65% either.
