Does this make sense? How the hell do you transfer that much energy in milliseconds? Especially with a battery that requires the flow of liquid?
If this is some sort of hybrid battery that could be possible... Super capacitors take the initial charge, pass it on to the flow battery. But as far as I know, absorbing or releasing a lot of energy quickly is just not what flow batteries do, it's their biggest limitation.
This article is complete bullshit. What they probably meant is that it can switch between energy input and output within milliseconds, which is realistic. Whoever wrote this lacks a basic understanding of the technology.
I mean, you COULD just have a massive membrane area. They won't, cause that'd be crazy, but you could.
From what I read, it does 800 MW max, which is still a lot.
1.2 GWh is just the capacity. And response time can indeed be quite fast as the system is always on standby, but I would guess it would still take a few seconds to go from zero to full power
But with 800 MW it takes an hour and a half to get to 1.2 GWh, and an hour is 3600 seconds or 3600000 ms. So "a few" is doing a lot of work in that quote.
The quote is obviously incorrect, perhaps the engineer meant to say "absorb 1.2 GWh and start providing power to the grid in a matter of milliseconds", and it was lost in translation.
